Is it going to work? Will it kill what you want it to? Is it going to harm anything else?

And a common question, particularly when it comes to using weed killers on lawns, is will grass grow back after Roundup?

Read on to find out, complete with essential tips and advice on how to save and regrow a damaged lawn if necessary.

Will Grass Grow Back After Weed Killer? Too Long, Didn’t Read

If you’re panicking because you think you’ve just sprayed a potent chemical where you shouldn’t, then here’s the answer up front:

It depends on the type of weed killer used, how much the grass has been exposed to, and the climate conditions, when it comes to whether the plant will bounce back or not.

But as a general rule of thumb, if you’ve not seen an improvement in your lawn or “dead grass” area after two weeks, then you can probably bet it’s not going to come back anytime soon.

If that’s the case, we’ve got some top tips coming up on how to return your lawn to its former glory, so you can stop hitting your head off a brick wall.

What is Roundup?

Roundup is the brand name of one of the most popular vegetation control products on the market, manufactured by Monsanto, which in turn was acquired by Bayer Pharmaceuticals in 2018.

Its most (infamous) ingredient is glyphosate, which is never too far away from the news, given that there’s evidence it is carcinogenic to us humans (when used in large quantities/incorrectly).

It’s a systemic, broad-spectrum herbicide, which basically means it attacks the system of a wide variety of plant life.

And it’s very potent at what it does.

Take a look at this article if you are looking for the best weed killers for driveways.

Top tip: There are many other branded weed killers that also use glyphosate as their active ingredient – not just Roundup. You should always make sure you know exactly what you’re spraying beforehand.

While this article uses the Roundup brand name, the same advice can be more or less said when using other glyphosate-based herbicides, or non-selective herbicide use on the lawn in general.

Selective and Non-Selective Herbicides

Without going into too much detail here, weed killers like Roundup are available in two distinct types – selective and non-selective herbicides.

Selective herbicides will only attack specific weeds – usually as noted on the product’s packaging or specifications.

Non-selective herbicides will damage or destroy pretty much any vegetation they touch – including desirable plant life, such as vegetables, flower beds, and – of course – grass.

(Check out this review of the best commercial-grade weed killers – most of which will be of the potent, non-selective variety.)

Why is this information important?

If you’ve sprayed a selective herbicide on your lawn – that has been specifically designed to tackle lawn weeds and leave the grass alone – then you shouldn’t have anything to worry about.

And Roundup manufactures a product that does just that – Roundup for Lawns. If using this particular weed killer, then grass will grow back, because it hasn’t been damaged in the first place.

However, if you’ve made a glaring error and accidentally sprayed a non-selective herbicide on your lawn, (such as the vast majority of Roundup’s other products), then you should keep reading to find out how to deal with it.

For more specific help, this article on the best weed killers for flower beds will advise you on what to lay down around desirable plants.

And this piece on pre-emergent herbicides is ideal if you need help preventing a weed problem before it’s begun.

Roundup and Grass – What You Need to Know

So, you’ve either chosen the wrong herbicide, or you’ve accidentally sprayed in the wrong place, or maybe you’ve been applying the weed killer during windy weather, and it’s dispersed from its intended location.

Either way, you suspect your lawn has taken a dose of a non-selective herbicide, and you’re panicking that you’ve killed it off.

Your immediate response should be to douse the area with a liberal spray from the hose – as watering the Roundup down will help to reduce its potency, and give your grass a better chance of recovery.

If, however, you were unaware that the herbicide has traveled, your lawn might only start to show signs of “burning,” several hours, or a few days after application.

Yellowing, brown, discolored grass patches begin to appear – a tell-tale sign of herbicide damage.

Why is this happening? It’s time for a brief lesson from grade nine biology.

Non-selective herbicides, such as glyphosate, work by inhibiting a plant’s ability to use photosynthesis – the process in which they use sunlight to help create food from carbon dioxide and water.

Take this ability away, and the plant will start to die.

The green pigment in a plant – chlorophyll – begins to turn color, which is unsightly and often concerning appearance we’re greeted with when looking at grass that has been damaged by chemicals.

But the key question is –  is this damage permanent?

It depends on how extensive it is, how much weed killer has been absorbed, how hot the climate is, and how long the plant has been exposed to the herbicide.

There’s nothing much more you can do at this point but to watch and wait.

The grass could well bounce back in a few days – that attractive green hue will start to return, and the crisis is averted.

But if you still have brown or yellow patches on your lawn for 14 days after application, then it’s going to be bad news, I’m afraid. There’s a strong chance the grass has been killed to the root and is gone for good.

In which case, you should read on to discover the next steps for lawn recovery.

How to Remove Dead Grass After Roundup

The worst-case scenario has occurred, and you have no chance of salvaging sections of your lawn. The deed is done, the grass is dead.

Long live the grass.

The good news is that all is not lost. Follow the steps below, and with a bit of hard work and the right conditions, a thriving, green, healthy lawn will soon return.

First, the dead material needs to be removed in order to establish a blank canvas. There are several ways in which to do this, and the type you choose will depend on the extent of the damage.

You might be able to use some good, old-fashioned elbow grease, get down on your knees and use your hands to strip the layers of dead vegetation away.

For tougher, more extensive spots, a dethatching rake should be implemented. Just be careful not to hack away at any desired, living material.

This article on the best dethatchers should help get you started.

And this article might offer additional help if you’ve discovered some unsightly yellow patches on your lawn.

But if your lawn is a total write-off, and/or the area is simply too large to do by hand, then you might want to look into using a sod cutter to lift the dead material away and start totally from scratch.

Either way, before attempting to regrow areas of dead grass, you should be down to the bare soil before a single seed is sown.

How to Regrow Grass After Roundup

Once the dead grass has been removed, and you’ve exposed the soil, you’re ready to start reestablishing your lawn.

This is where the hard work really begins.

But you actually don’t want to rush in – especially after the damage has been done by initially spraying herbicides.

How long you wait before applying grass seed will depend on the chemical that’s been applied in the first place. Check with the particular product you’ve used.

For the most part, you’re looking at a minimum of three days before new seeds can be applied.

Next, (if you have any lawn left) you should mow the grass down to the lowest setting on your lawnmower. This article on the different types of lawnmowers will help make sure you’re using the right one.

Then, simply follow the advice in the video below, which offers a great visual guide on how to regrow areas of your lawn that have died.

But perhaps one of the most important steps when it comes to growing a healthy lawn, is how best to water it. Too much is just as bad as too little, which is particularly critical when it comes to new growth.

This in-depth article on how to water your lawn should tell you everything you need to know.

Final Thoughts

Here at Yardthyme we always try to promote organic ways to care for your lawn and garden. This article on how to get rid of dandelions naturally is a good example.

This piece on pet-safe weed killers is another.

But we recognize that sometimes a powerful chemical herbicide is the only thing that will do.

That said, always take the greatest of care when choosing this course of action, and only as a last resort if you can help it.

Unfortunately, such potent herbicides are often a necessary evil for achieving the landscape of our dreams. In the end, Mother Nature always wins.

FAQs

Is Roundup safe to use?

Yes and no. It’s a bone of contention in the agricultural community, as there is maybe some evidence to suggest it’s harmful if used in large quantities, and it’s certainly harmful if used improperly.

And there’s no denying it’s not safe for the plants it’s used on.

For residential use, caution is advised – particularly when spraying near desirables, in windy or rainy conditions, and/or if you have children/pets.

If you are genuinely concerned about its usage, you can take a look at this article on the best alternatives to Roundup.

However, at the time of writing, the US Environmental Protection Agency has found no evidence that there is any detriment to human health from the use of glyphosate.

And Bayer, the pharmaceutical company that manufactures this particular brand, has stated that they will be offering weed killer products under the Roundup name that contain alternative ingredients.

How long will Roundup stay in the soil?

Roundup can stay in the soil anywhere from three days to over a year – it just depends on the type of product you’ve used, and how much has been applied.

It can also depend upon the climate and type of soil it’s in.

When in doubt, check directly with the manufacturer of the specific glyphosate-based product you’ve used.

How long after spraying Roundup can you sow grass seed?

Depending on the type of Roundup, it is recommended that you wait a minimum of three days before attempting to sow any new grass seed.

Will Roundup kill Bermuda grass?

Provided you’re using a non-selective version of Roundup, then there’s a strong chance it will kill Bermuda grass.

However, as this plant can be a particular nuisance when it’s not wanted, it’s highly recommended that you take a look at something that specifically targets the golf-course favorite grass.

Can check out this review of the best weed killers for Bermuda grass on the market.

Summary

Will grass grow back after Roundup? It depends on a number of factors, but so long as the plant hasn’t been exposed to too much of the chemical, and it’s given a chance to return, then you might get lucky.

Follow the advice and the steps above, and you won’t go too far wrong. Remember – it might look bleak, but with the right conditions, nature will find a way.

Let me know your lawn and herbicide experience in the comments, stay safe out there, and happy gardening!

Green and healthy grass can seem like a dream out of reach for most gardeners and trust me, I’ve been there: you’re sick to death of those sneaky weeds that infiltrate your garden, popping up to say “hello” at the worst of times!

Before treating these bad boys, you need to be able to identify them as you need to find the right weedkiller – or organic method – that can tackle the job once and for all!

But how do we identify them, I hear you ask?

And how do we get rid of them?

Worry not my friends, because if you read on, you’ll find the most common lawn weeds that you probably find in your garden as well as how to treat them!

What are Weeds?

People don’t like to admit they have a weed problem in their garden, I know I don’t but the first step to combatting this issue is by admitting it and identifying them.

So, what is are weeds then?

There are three key terms used to identify the behavior and type of weed, these include the generic term: Common Weed, as well as other, more specific terms, Noxious Weed, and Invasive Weed.

Common Weed: “A wild plant growing where it is not wanted and in competition with cultivated plants.”

The keyword I take from that definition is “competition”.

Weeds are unwanted and pesky, and they can drain the life out of your other wanted plants, causing them to be a massive issue in the health and longevity of your garden!

Noxious Weed: “A weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock.”

Invasive Weed: “An alien species of plant that shows a tendency to spread out of control. The label “invasive” is generally reserved for plants that have been introduced from other regions and spread like wildfire in their new habitats.”

What Causes Weeds?

Weeds are opportunists, they grow when the conditions are right such as in moist or dry turf, and varying temperature levels. Many weeds are the product of poor lawn care and can thrive on this negligence.

When your garden is suffering from lawn disease, this causes dry and thin turf areas in which the weeds can take advantage of, if you want to prevent weeds you need to prevent lawn disease and there are many types that can affect the health of your grass.

Lawn disease is a factor that can create dry grass; however, weeds can also grow in the moist and warm grass, especially in those which have been overwatered creating a fungus and moss infliction.

Moss is desirable in the right setting; it is definitely not desirable on your lawn which can attract certain weeds as well as spread itself – not ideal!

You can easily get rid of moss in your lawn naturally with the right methods that will preserve the health of your grass.

Most Common Lawn Weeds in the USA

There are many species of weeds that can be found globally, however, for the purpose of this blog, I will be talking about the most common weeds that can be found in the USA.

These most popular weed species can be categorized into noxious weeds or invasive weeds, and common weeds.

Noxious Weeds

Noxious weeds are destructive and can pose a risk in your garden. These weeds are remarkably hard to get rid of when using regular weed killing methods.

These weeds, as stated above, can be injurious to agriculture, so imagine how they can impact your regular garden!

Field Bindweed

Field bindweed is a perennial vine that dies down only once a year and can be found throughout the US except for the most southern regions. It has many names allocated such as wild-morning glory; not to be confused with the ornamental ‘morning glory’ which is an annual plant.

Originating from Eurasia, field bindweed is of the hardiest and difficult to combat weeds. It can spread from roots as well as from seeds. These weeds’ roots are found to reach depths of 14 feet!

A single field bindweed plant can spread its roots more than 10 feet in a single growing season!

The leaves of this plant can be identified by their spiral arrangement and arrowhead shape. The flowers are a deep trumpet shape with colors of white and pale pink. These flowers blossom in the mid-to-late summer and produce fruits with two seeds in each, these seeds can be eaten by birds or can lay dormant in the soil for decades.

The feature that causes this weed to be considered ‘noxious’ is the way in which it spreads and survives.

The deep roots make it hard to kill completely meaning whilst on surface-level weed killer might do the job, the roots far extension means it can survive as well as reproduce in a matter of time!

Moreover, above ground level, the stems of this plant can twist around the stems of other plants, climbing in a counterclockwise direction. This can suffocate your beloved plants as it is essentially choking them!

How to Prevent and Kill Field Bindweed

This notorious weed is unfortunately fearless to many tilling and cultivation methods as this can sometimes cause it to spread even further! Leaving even an inch of the root can mean it will most likely resprout and surprise you next season.

On top of this, field bindweed is drought-resistant, and once established, commercial weed killers are not enough to get rid of these weeds.

The best way in which you can stop these plants is through early prevention.

Many weeds are tackled through this method and are known to be very effective if started at the right time. This method is very reliant on proper lawn care such as watering and using the right tools.

In partnership with this, you’ll need to extract the seedlings when they’re about 3-4 weeks old, as soon after that the buds start to form and it’s pretty much downhill from there.

A long-term prevention method that you can use is light exclusion.

Bindweed grows well in mulches through the loose gaps; therefore, you need to close these gaps by placing a landscaping fabric over the top of the soil and then apply mulch on top.

After around three years, this light exclusion method will be the most effective way of getting rid of bindweed but be aware that the roots and seeds can lay dormant for decades, so you’ll need to keep an eye out for early sprouts!

Ragweed

Ragweed is known to be the cause of hay fever during springtime. This noxious weed can be found in every state of America except Alaska and has even been introduced to Hawaii, however, the main environment where ragweed truly thrives is in the Midwest and Northeast regions.

This weed has an abundance of different variants and all of which are super annoying! These variants can grow in fields and even between cracks of pavement.

Ragweed season peaks in mid-September, however, the plants start pollinating as early as July. Every single plant during pollination can produce over one billion pollen grains causing some major hay fever as well as worsen asthma in the spring.

The behavior of this plant is what makes it noxious, its roots are called taproots and are extremely strong and hardy; if any of these roots are left behind in the soil it poses a risk of resprouting.

Alongside this, the seeds offer the biggest risk as they can spread like wildfire and can travel through bodies of water as well as wind.

This weed can be distinguished by its leaf shape with its spear-shaped blades that protrude outwardly into lobes. The flowers of this weed are stamens with white and purple florets. These florets contain seeds and are wind-pollinated.

How to Prevent Ragweed

Once spotted, ragweed can be killed with a broadleaf weed killer or other general commercial weed killers. For this to be effective, it needs to be done when the seedlings are young, and the roots aren’t established enough as that will cause the response to the weed killer to be better.

Another progressive preventative method is by mowing your lawn regularly. Mowing will aid against the ragweed sprouting flowers and spreading seeds.

If you want a more natural approach to killing weeds, ragweed is one of the more responsive to this method than other noxious weeds. Again, this needs to be done as early as possible to prevent further spread. These natural methods include using vinegar as well as boiling water.

Quack Grass

Quack grass is a creeping perennial weed that resembles closely to ryegrass and crabgrass, however, can be easily noticed through its thick stem and taller blades.

The areas in which this weed is most common include the northern portion of America and is extremely prominent in Ohio. It thrives mostly in crop fields, gardens, and roadsides.

This weed forms a heavy and matted formation that allows roots to spread and cultivate further, causing this plant to be considered invasive and noxious.

How to Kill and Prevent Quack Grass

Quack grass can be killed using a non-selective herbicide with the active ingredient being Glyphosate. This, however, can also kill traditional garden grass as well as ornamental plants so take care to only place it directly on the quack grass.

If you want pet-safe weed killers for your garden and weed problems, be sure to visit that post for more information!

Another way in which you can prevent and kill quack grass is by pulling it at the roots. You need to ensure that you do this effectively and with the right method so you don’t leave any of the roots leftover that could cause regrowth!

If you do use this method, you need to dispose of the plant in a waste bin as if you put it on a compost heap it can re-root and grow there.

Dandelion

Aaah the common dandelion.

This weed is dreaded in all gardens due to its deep taproot that extends over 15 feet! The puffball seed-head means that with and a gust of wind, the seeds will blow and germinate in any garden it lands in.

Dandelions grow in all areas of America; they don’t discriminate as they can thrive in pretty much all settings.

How to Prevent and Kill Dandelions

The most effective way to prevent dandelions from future sprouting is proper lawn care. Dandelions grow in loose and unrooted grass areas; many people experience dandelions growing in newly laid grass that has a weak root system.

To prevent this, you need to create a dense and healthy lawn through regular watering and mowing, as well as reseeding dry areas. This will be a long-term preventative method that you can use to extend the health of your lawn!

Aside from long-term methods, you can use weedkillers that are most suited for deep root extermination.

For more ways that you can use to get rid of dandelions, read my article here!

Pigweed

Pretty much every farmer in North America has had their struggle with pigweed. It wins the title as one of THE most troublesome common weed types that can affect basically any garden.

This weed thrives in summer and can be an exhausting issue throughout all of America – as well as globally! The pigweed name is actually a term that has several species attached, and all of which are a pain to get rid of.

These weeds love the summer heat. They emerge after spring and wreak havoc all summer in many gardens and crop fields, only to die in fall.

They can be distinguished by their leaf shape being broad and rounded with a pointed tip. Their flowers are similar to that of ragweed and carry seeds within their flowers.

How to Kill and Prevent Pigweed

Word of advice when dealing with this plant: pull it out before it flowers!

Another method that is tried and true in preventing the spread of pigweed is by applying a layer of winter mulch to your garden. The seeds of this weed need sunlight to germinate, so by covering this weed with mulch you are starving it of the nutrients it requires!

Purslane

Whilst purslane is considered noxious in one US state, it is actually a more common weed.

This weed can be identified through its succulent nature with rounded green and red leaves.

Why is this plant such a headache?

This plant is an issue due to its high spreadable nature for each plant can produce 2 million seeds!

Once these seeds have spread, this plant can flourish and grow in pretty much all environments. Aside from this, purslane can also grow through its leaves spreading the growth even further.

Purslane, due to its succulent-type behavior can survive in dry conditions, however, prefers moist soil and warm weather.

How to Prevent and Kill Purslane

Purslane can be eradicated through simple weed pulling. Unfortunately, purslane is most responsive to preventative measures rather than herbicide.

This plant can live in your soil for long periods of time and little seedlings can pop up unexpectedly, so the minute you see one pull it out ASAP!

Regular mulching and aeration of the soil will also prevent this weed from growing as it makes it hard to establish a deep root system. Using synthetic mulches will also help to filter out light, hence draining the plant of its nutrient source.

Summary

Weeds are a common issue that so many people face and can drive you to the brink of crazy – I’ve been there.

Now that you know the most common weeds, noxious and common, and how to identify them, you’ll be able to protect your garden from their future invasion!

Whilst they can be unavoidable, weeds are can be contained, so let me know in the comments if you’ve had any success with tackling your garden weed problem, and feel free to share this article with anyone suffering too!

One thing is clear – as there are many types of diseases and weeds, there are also a lot of weed killer types and disease treatments available.

Fighting more than just weeds in your lawn and old stumps are in the way to the perfect lawn? We have reviewed some of the best stump killers that will help you with this problem.

So, it’s understandable that keeping them out of your garden is preferable.

Unfortunately, snails are often unfairly lumped in with slugs and seen as something that should be eradicated. In reality, the damage they cause is usually fairly minimal.

But do they provide any benefits? Should we be rethinking how we see these little critters?

Read on to find out!

Benefits of Snails in the Garden

The primary benefits of snails in the garden, center around the fact that they are part of the natural ecosystem and have a role to play in keeping everything in balance.

Us humans are pretty arrogant when it comes to deciding what should be allowed to live, and what should be designated a pest and eradicated.

Often our efforts to ‘control’ one species, leads to an imbalance in the numbers of other species. This chain reaction can result in other animals becoming labeled as pests while others become threatened.

The best policy is always to try and support the natural balance of the environment and its ecosystems. And snails are a natural part of that ecosystem.

Benefits of Snails in the Garden Include:

Though they’re definitely less attractive and more damaging, slugs also play a role in the ecosystem. The benefits of slugs in the garden are actually very similar to snails.

They provide a food source for many animals higher up the food chain and they help to decompose decaying organic matter, creating fertilizer.

But, unlike slugs, snails don’t actually cause much damage.

The benefits may not blow you away, but snails are certainly not a cause for concern the way slugs might be, and there should be no reason to control their numbers unless something is very wrong in the balance of your garden’s ecosystem.

So, let’s talk about how to support that balance.

Supporting the Natural Balance of Your Garden

In the world of permaculture, there is no such thing as ‘too many slugs’, just ‘not enough ducks’ to eat them.

While keeping ducks in your garden as a means of slug and snail control is likely not a viable option, this sentiment highlights the fact that an abundance of slugs and snails represents an imbalance in your garden ecosystem.

Ironically, this imbalance could, in part, be caused by pest management strategies such as slug pellets which are also fatal to the very animals who feed on slugs and snails and would otherwise be helping to keep their numbers down.

Interestingly, the presence of snails may be seen differently in different places. In some parts of the world, for example, Germany, you can mail order certain species of snails to deliberately introduce into your garden for the benefits they bring.

So, What Can You Do to Keep the Peace?

Encourage Predatory Animals to Your Garden

This is a surefire way of keeping slugs and snails in check.

Building a small wildlife pond and putting out bird feeders are ways of doing this that help to support these animals when conditions are tough in the winter as well.

Keep Things Tidy, but Not Too Tidy

f you’re of the opinion that a well-maintained garden looks like you’ve gone over the lawn with a vacuum cleaner, you might be in for some trouble.

Fallen leaves break down to feed the soil as well as snails (meaning less work for you as you won’t need to fertilize!). A little bit of debris also creates homes for wildlife such as snails, insects, and the predatory animals that will eat said snails and insects.

Having a garden that is too perfectly manicured means there are limited places for animals to form their homes and find food sources.

On the other hand, a completely overgrown garden will provide ample places to call home and find food so may not be the best option if you’re trying to limit slug and snail numbers. So again, it comes down to balance.

Keep Things Light, Airy and Not Too Wet

Snails love dark and wet. As with the above point, you want to keep some snail-friendly habitat, but you can easily avoid their numbers growing if you keep your garden from getting too soggy.

Using drip feed irrigation rather than a sprinkler might help to target water where you want it without wetting a large area of foliage (which snails would prefer). Using a soaker hose is the best way of doing this.

Practice Companion Planting

Snails have a preference for some plants (lettuces, brassicas, cabbages, dahlias, hostas and marigolds) while disliking others (lavender, rosemary, hydrangeas, geraniums). Planting things that snails don’t like next to the things that they do can help prevent them from getting too excited.

There are also natural methods that you can use to discourage snails from vulnerable plants and avoid having to use toxic slug pellets.

Handpick After Dark

Snails are nocturnal, so going outside with your torch after dark and hand removing any snails that you find is the most favored management technique by many experienced gardeners.

You’ll probably want to wear garden gloves, especially if you’re going after slugs at the same time. Just be sure to toss them more than 40m away to overcome their homing instinct!

(If you’re not sure where to toss them, you could always add them to your compost heap – they’ll help with the decomposing and there’ll be plenty there to eat. If you don’t have a compost yet, have a read of this guide to the best compost tumblers to get started.)

Create a Barrier

Things like coffee grounds, crushed eggshells, diatomaceous earth, and ash can help to deter snails from a certain area as they’ll find it hard to slither over that surface.

Keeping plants that are popular with snails in raised beds or large plant pots is also a good option as it’s further for them to travel and easier to catch them in the act.

Set Up a Beer Trap

Snails and slugs love the smell of beer so setting up a beer trap is a great way to lure them away from your precious plants. Set a dish of beer in the soil, deep enough that once they fall in, they’ll drown.

Slug Pellets as a Last Resort

Slug pellets should only be an absolute last resort, if you have a serious, serious infestation, which, let’s face it, is unlikely. If you just don’t like the look of a few snails in your garden, then create an environment that doesn’t attract them rather than resorting to toxic pesticides.

The main ingredient in conventional slug pellets, Metaldehyde, is currently being banned in the UK due to the harmful impact it has on wildlife. Metaldehyde has also been found in drinking water supplies. If you absolutely have to use slug pellets, look for versions that don’t contain Metaldehyde and that list themselves as safe for pets.

Just getting into gardening? Top Tip: One of the most useful but surprising items that you could set yourself up with is a garden kneeler. Save your knees and garden in comfort!

Summary

So, are snails good for the garden?

While the benefits listed don’t translate directly into benefits that you’ll see in terms of flourishing plants, in this day and age, with so many natural balances drastically upset by humans, keeping a bit more of a balance in your garden by allowing snails to cohabitate in reasonable numbers can only be a good thing.

So, I’m going to say yes. Snails are good for your garden. They have their place in the ecosystem, and removing them will definitely cause more harm than good.

What’s your experience?

Designed for organic use, this concentrated herbicide is a post-emergent weed killer and safe to use around people and pets.

Pros

Cons

RM43 Glyphosate Plus Weed Preventer

Here we have a classic example of a commercial total vegetation control product, that incorporates a powerful weed killer and preventer.

A persistent herbicide, RM43 will not only destroy all vegetation it comes into contact with, but it will keep any treated site weed-free for up to one year.

You’re guaranteed excellent coverage, too, as one gallon is capable of 17,297 square feet of weed control.

Ideal for use along fence rows, and around farm buildings and barns, this is an industrial-style herbicide that you can use in the home – just make sure you take great care when and where you dispense it.

Prodiamine 65 is a pre-emergent herbicide to provide you with excellent grass and broadleaf weed control. Ideal for use in both spring and fall, you can achieve season-long protection against crabgrass and other undesirable weeds in your desirable turfgrass.

A professional product, it’s best for use around nurseries, trees, established perennials, and wildflower plantings, and any non-crop region you wish to control annual bluegrass (poa annua), henbit, knotweed, chickweed, spurge, foxtail, and goosegrass.

One of the best commercial weed killers for lawns there is, and a solid alternative to more well-known brand names.

Pros

Cons

Round Up Pro Concentrate Systemic Herbicide

Now, this is interesting. This particular product is called Roundup Pro, and at 50.2% it has one of the highest amounts of glyphosate as the active ingredient in any commercially available weed killer (with Roundup Quik Pro being the only one higher).

However, it’s manufactured by Monsanto, a company that is actually no more, and one that has something of a checkered past – including controversies surrounding Roundup itself.

It seems this very potent, post-emergent herbicide is still readily available, so it’s up to you to decide if you’re happy using it on and around your property with a clear conscience.

Pros

Cons

Tenacity Turf Herbicide

Although this looks like it comes in such a small quantity (a syringe is included), this eight-ounce bottle is actually deceptively potent and will make up to 96 gallons of herbicide with 1/2 a teaspoon per gallon of water.

It should last you a long time with correct use.

Designed as both a pre-emergent and post-emergent herbicide for the selective contact and residual control of weeds in turf grasses, it will tackle over 46 nuisance broadleaf and grass species.

Tenacity’s active ingredient is 40% mesotrione, which is a naturally occurring compound – so you’re not using any harsh chemicals here. Very highly rated, this is a professional-grade product that will help you achieve excellent results for your lawns.

Pros

Cons

Milestone Specialty Herbicide

Milestone is another broad-spectrum weed killer for use on noxious and invasive species that appear in your lawn.

Best used to attack broadleaf weeds, like the Tenacity, it kills by both a post and pre-emergent effect, offering a super-fast knockdown within 24 hours, and long-lasting, residual control so weeds don’t come back.

No mixing is required, and it’s selective on most warm and cool-season grasses. Designed for commercial and agricultural use, it’s a potent weed killer that will also kill trees and shrubs should you require it to do that.

Another highly rated herbicide that will do the job it’s supposed to do – and then some. Just be careful you’re not spraying it on a windy day.

Pros

Cons

How to Choose the Best Commercial Weed Killer

There’s a lot to consider before you add your chosen commercial weed killer to the cart. Below, you’ll find a buyer’s guide that explains everything you should be looking out for.

Strength/Active Ingredients

Since we’re talking about commercial weed killers, perhaps the most important thing to consider is just how strong the product is.

Commercial herbicides are designed to be used by farmers, landscape professionals, around industrial and commercial sites, and at sport and leisure facilities – such as golf courses.

And these folks aren’t messing around – they want this nuisance vegetation dead.

With that in mind, you’ll find these products often contain some of the harshest chemicals and compounds – including the infamous glyphosate – which has been making headlines around the world in recent years.

There’s no doubt its ability to kill plants, but it’s the potential effects on humans and animals that are causing a stir.

When choosing a commercial herbicide for use around your home, check the active ingredients and their potency, and take great care when applying products of this strength.

Take into consideration water run-off, where you’re applying these chemicals, and if you have children or pets running around.

And if you prefer something a little milder, check out this review of the best pet-safe weed killers on the market.

For more information, and a short, crash-course in herbicide basics (including a word on the strength) check out the video below.

Selectivity

Another of the most important factors to consider when choosing a weed killer is in understanding what it is actually going to kill.

A selective weed killer will only attack certain plants and vegetation while leaving other species alone.

For residential purposes, perhaps the best use of a selective herbicide is on your lawn – where you certainly don’t want to kill off the desired grass, but you want to rid yourself of an invasive weed.

Of course, if you prefer not to use anything potentially harsh on your lawn, have a read of this article on how to remove weeds from your lawn without chemicals.

A non-selective weed killer will eliminate just about everything green that it comes into contact with.

They are the most potent of herbicides and should be used with great care, particularly around plants and vegetation that you want to keep.

Non-selective herbicides are ideal for use over larger areas where you simply want everything dead, and you’re not risking killing off anything desirable.

Aside from understanding selectivity, it’s also worth noting if the weed killer you’re interested in actually kills the species you want to remove.

Checking the label, reading online reviews, and listening to feedback from people who have actually been successful/unsuccessful with the product is an excellent way to figure out if it’s right for you.

For example, nettles can be an obnoxious, nuisance weed that are difficult to eradicate, so check out this dedicated article on how to get rid of nettles for more in-depth advice.

Pre/Post-Emergent

The life of a weed also needs to be understood (at least by the boffins in the chemical biology labs) in order to know how best to kill it.

With this in mind, three types of herbicides are readily available and are explained below.

Pre-plant herbicides will be used well before any weeds have had the chance to germinate, and in areas where a desirable crop is to be planted in the future.

Pre-emergent herbicides will kill the weed growth before germination, or before you see any vegetation breaking through the soil.

Post-emergent herbicides are specifically designed to destroy any existing and visible weeds that have sprouted and taken hold.

It should also be noted that post-emergent herbicides will either be ‘contact’ or ‘systemic.’ A contact herbicide will only kill what it touches, whereas a systemic herbicide will make its way through the plant and kill it from the root.

All commercial weed killers will fall under one of these categories, and it’s up to you to decide which you think will work best for your situation.

Persistence

When talking about the persistence of a weed killer, it’s simply referring to the length of time it will stay active in the soil after application. You will notice there are two types.

Persistent herbicides will prevent weeds from regrowing over a set period of time. This can vary from a few days or months, to up to a year and possibly more – depending on the strength.

Also called residual weed killers, they reside in the soil and are generally used in areas you want to keep clear of all plant life for as long as possible – without the need for further chemical application. Clearing weeds from driveways is a good example.

Non-persistent herbicides are exactly the opposite. They do not prevent any future regrowth, so plant life will come back to the treated area eventually.

While this might seem disadvantageous for weed killing, it’s more so that future crops can be planted in that soil.

Which type you choose will depend on what you want to achieve in certain areas around your garden over time.

Quantity

Commercial herbicides usually come in large quantities as more often than not they’re required to cover enormous areas.

Having said that, you can still purchase these formulas in smaller amounts, in spray or trigger guns, for example, to spot-treat, particularly stubborn weeds.

Remember, purchasing larger quantities will be more cost-effective in the long-run, but always choose the amount that suits your property and weed murdering requirements.

Application Methods

As well as coming in a variety of quantities, commercial weed killers are available in a variety of states and require suitable application methods to dispense destruction.

For smaller areas, trigger or spray guns will be suitable – especially if you just need to spot-treat one or two weeds.

If you need a step up from this, larger bottles are available that often come with their own spray applicator nozzle.

When treating lawns, granular weed killers are more common and are dispensed by using a lawn or seed spreader. They can also be useful around flower beds.

For larger areas, tank or backpack sprayers work best, usually with some kind of concentrate liquid herbicide that you need to dilute with water before applying.

And some herbicides require (or work best with) a surfactant – which changes the surface tension of the liquid and the target area it’s being applied to. This greatly helps it to penetrate the surface for more successful results.

A Note on Brand Names

If you were to ask anyone to name a weed killer, the chances are they would respond with “Roundup.”

While it’s the most famous brand name herbicide (certainly in the US and Canada), does it necessarily make a difference when it comes to actual results?

The answer is no.

Being the most well-known doesn’t always equate to being the best.

Having said that, there’s no doubting Roundup’s pedigree for weed massacre, it’s just that similar weed killers with almost identical ingredients also exist.

This is especially true after the glyphosate patent expired back in 2000 – and anyone can use that chemical formula in their weed killer products should they so wish.

In short, in the weed-killing world, although the brand name products have established themselves a loyal customer base – what works for one gardener might not work for you.

It might be worth a bit of trial and error – and you could end up discovering something that provides excellent results at a fraction of the cost.

Summary

Choosing the right herbicide for your needs isn’t as straightforward as you might think, as there are all kinds of products and formulas on the market, as the multiple gardening situations and scenarios that they cover.

But if you really just want to kill those pesky plants stone dead, then you need to add the best commercial weed killer to your ranks.

I hope this article has helped you discover the one that’s right for you, and let me know in the comments which product you have chosen and why.

Ground hornets are almost impossible to miss since they have large bodies. Their physique helps them catch other bugs, and they have a very predatory nature. If you notice these imposing bees flying around your home, it is best to learn how to get rid of ground hornets in case they are living close by.

The Basics of Ground Hornets

Hornets are larger than ground bees and have a more dangerous sting. There is no difference between ground hornets and tree hornets when it comes to size. They choose a different place to build their nest, and that’s it.

Ground hornets can inhabit walls as well as old tree stumps. However, their favorite place is dry or loose soil.

Just like every animal that digs holes in the yard, hornets don’t like obstacles. They could also live in flowerbeds. Considering their nests are underground, the removal is a bit tricky but not impossible.

If you want to know when are ground hornets least active so you could remove the nest, the answer is at night. They have poor sight and usually don’t come out after dark.

Of course, wearing protective gear such as thick landscaping gloves is recommended because some hornets might get out of the nest and try to deal with the attacker, and that’s you. Seek immediate ground hornets sting treatment in case of an allergy.

How to Get Rid of Ground Hornets: 3 Methods

Soap and Water Mixture

If you ever had to deal with ground wasps, you already know that soap and water mixture is the easiest way to get rid of them. The same method can be applied to ground hornets.

First, you need to locate the nest and cover the entrance with a fabric. Secure it in place, so it doesn’t move. Then pour the mixture of soap and water into the hole.

Water should drown the hornets that are in the nest as the fabric prevents them from swarming out. Soap will immobilize their wings and make flying impossible. Leave the nest overnight with the covering and remove it in the morning.

A DIY Hornet Trap

You haven’t located the nest yet, but hornets are making you uncomfortable? A DIY trap might be the best solution. It is the most effective way of minimizing the number of hornets in your vicinity without applying insecticides.

Pet owners and people who don’t like using chemicals in their yard often choose this method.

You will need a soda bottle for this, the larger, the better. Cut it at the neck and put some olive oil or something sweet on the inside. Pour some water in as well. Turn the piece you have just cut off, remove the cap, and place it back into the bottle.

You could also make holes on the side if you plan to hang the trap.

Hornets will be attracted to whatever you choose to put inside. Don’t neglect the trap and empty it as often as possible. You could also add a couple of drops of soap if you are worried that ground hornets might not drown right away.

Insecticide Dust

Insecticide dust is the best way to get rid of ground hornets around plants. Contrary to popular belief, these chemicals will not affect flowers in your garden.

When you purchase the insecticide dust, make sure you get the additional equipment as well. It includes a duster with a long pole that will help you spray the nest without getting too close.

You also need to use insecticide dust at a specific time. Ground hornets should be in the nest when you spray, so do it during the night or before dawn. The dust should be applied directly into the opening.

After that, wait for two to three days before getting close to the nest to inspect the results.

The Prevention

Now that you have removed the colony from your garden, it might be the perfect time to learn how to prevent ground hornets from building nests again.

If you have used poison or any other chemical, hornets will know that returning to their previous nest is out of the question, especially if the queen is dead.

You can also make your yard unliveable for them. This is quite simple because hornets love dry and quiet places. So take good care of your lawn by mowing it regularly and keeping the ground moist. Focus on flowerbeds as well.

FAQs

Is it safe to mow the yard if I have ground hornets?

Ground hornets are not aggressive unless they sense danger. Coming super close to their nest with a lawnmower is considered a threat, and the chances are you will be attacked.

The entrance to the nest is small and almost invisible so you might bump into it by accident. Those of you who have noticed a lot of hornets flying around your garden lately should locate the nest first. Then mow the lawn and keep a safe distance from the hornets.

Are ground hornets aggressive?

Hornets are overly protective but will not sting a human without being provoked. Guarding the nest is their number one priority, and anyone who comes close to it could be attacked by these bees.

Each nest has a “team” that stays close to the entrance of the nest. Once they sense something is up, the guards will alert the rest of the colony. It is also important to mention that hornets can sting several times since their stinger doesn’t fall off.

Does killing a hornet attract more?

The short answer is yes. If you kill a hornet close to its nest, the chances are you will summon the entire colony to come after you. A dead hornet releases a pheromone that immediately attracts other nearby hornets.

Remember that a couple of stings may not be deadly, but if a colony attacks you, the aftermath could be horrible.

Where do hornets go when their nest is destroyed?

Do you want to learn how to destroy an in-ground hornets’ nest, but curious about where they will go afterward?

Some hornets will return to the site and hang around for a couple of days, trying to communicate with other surviving members of the colony.

They could try to rebuild it in another location if the queen is alive. If not, hornets will try to get accepted to another nest or die on their own.

What smells do hornets hate?

Both wasps and hornets are repulsed by the smell of peppermint. You can keep them away from your garden by planting some peppermint in the flowerbeds.

Optionally, use peppermint oil and spray your yard now and then. It is completely natural and pet-safe.

They are also not fond of wormwood, citronella, eucalyptus, and spearmint.

Summary

Learning how to kill ground hornets can come in handy if you want to spend a lot of time in your yard without constantly thinking you might get stung. Ground hornets are not solitary bees, and they create large colonies.

There are several methods you could use against them, and some require things you already have in the household, such as water and soap.

If you want to know what kills ground hornets most effectively, the answer would be insecticide dust because it is a type of poison. It works quickly and can destroy an entire colony without putting you and your family at risk.

But whatever option you choose, make sure you are well protected when you go out there to deal with ground hornets.

The problem is, we’re not alone in enjoying this climate, as unsightly, unwanted visitors start to return in an attempt to ruin everything.

I am, of course, talking about weeds.

And if your property is on the larger side, then they can be even more of a nuisance to eradicate.

So, in a series of articles dedicated to destroying problematic vegetation, let’s first take a look at the best weed killers for large areas.

A buyer’s guide with helpful tips and tricks will follow.

How to Choose the Best Weed Killer for Large Areas

Below, you’ll find an informative buyer’s guide to help you choose the right product for you and your property.

Size of Area/Quantity

First, you’ll want to find out just how much area you need to cover, and then you can ascertain the quantity of the product you require. If you’re reading this page at all, it’s likely you need something that will cover larger spaces.

This is where concentrated weed killer products are king. Simply mix with the right amount of water for weed control over thousands of square feet.

Each weed killer is different though – so be sure to read the directions thoroughly in order to create the perfect concoction.

This might take some trial and error, too – as many users report that the given mixing instructions aren’t always the best depending on site and situation.

Be ready to adapt and create the right water to product ratio that will work for you.

Type of Area

When faced with so many options of weed killers, it might be overwhelming at first when it comes to choosing the right one.

But if you take a deep breath, and stop to check each product, you’ll discover that they all have different uses – and can be used in different areas.

So, as well as ascertaining just how large your weed-killing area needs to be, you also need to pay attention to the type.

Do you need to kill weeds on your lawn, among flower beds, around trees and shrubs, through the decking, along fences, in vegetable patches, on patios, driveways, and walkways…?

The list of places where weeds can spring up is seemingly endless, so too the list of products that will kill them.

Make sure you select the right weed-killer for the type of area you’re going to cover – it’s not one-size-fits-all, and using the wrong formula in the wrong area could have seriously negative results.

Emergence

Herbicides are available in a variety of forms and can be applied at three different times in the life-cycle of weeds and plant life.

Choosing the correct type will make your life much easier and give you the results you’re looking for.

Persistence and Selectivity

How long do you want the herbicide to keep working on your property, and what type of vegetation do you want it to attack?

A weed killer that keeps plants away for a long period of time is great if you want an area of your garden completely devoid of life – but useless if you want to cultivate desirable plants or vegetables.

Likewise, using a fast-acting weed killer that doesn’t last long in the soil will be ineffective at keeping weeds at bay through the season.

You should also consider if the herbicide is selective or non-selective.

Selective herbicides are designed to specifically destroy certain types of plant life, whereas non-selective will kill just about anything.

Active Ingredients

There are many compounds, formulas, and mixes that will attack and kill plant life. Some of them are also dangerous to humans and animals, others less so.

Keeping that in mind, it’s worth considering the main (active) ingredient in a weed killer – especially if you’re conscientious of where you’re going to be using it, and whether you have children or pets.

Glyphosate in particular has attracted a lot of media attention in recent years and is banned in some states and many countries around the world.

A broad-spectrum systemic herbicide and crop desiccant, it’s highly potent and effective at eliminating weeds, but the jury is out on how dangerous it is to humans.

That’s just one, high-profile example, but you should always take the time to consider what is in any weed killer you choose to purchase.

Application Method

Another often confusing factor about herbicides is just how they are applied. They come in a variety of forms and formulas, and the application instructions regularly lead people to scratch their heads.

Herbicides can be scattered on the ground in granule form, or they can be water-soluble granules and dissolved to make a potent concoction. They can be applied neatly in a spray bottle, or they can be diluted and dispensed from a tank, or attached to a hose and distributed that way.

The latter two application methods are more common for larger areas.

Make sure you understand how your chosen product is dispensed before purchasing – and that you have the necessary equipment to use it. Tank sprayers and granule spreaders are sold separately – and a good one can be expensive.

Check out the video below for advice on how to use a tank sprayer.

Brand Names

Do they matter? Some say yes, but when it comes to herbicides, it’s a case of six of one, half a dozen of the other that a brand-name product will perform any better than a budget version that has exactly the same ingredients.

Roundup is perhaps the most famous weed killer on the market, but you’ll find it’s not always the best, particularly if you want to stay away from harsh chemicals.

There are many more options out there, some branded, some not, all claiming to be effective at the job they’ve been designed to do.

Do your research, check reviews for similar weed-killer environments to yours, and go with your gut.

And if you’re still in doubt, try a few options and see which one works best for you.

Keep in mind that for larger areas, you might want to be looking at some of the best commercial weed killers, that will certainly do the job.

It’s definitely good to learn more about the available options as there are so many types of weed killers available on market.

Cost

When choosing the best weed killer for large overgrown areas, it’s important to take into consideration the cost of the product.

This is where you need to weigh up the value for money when it comes to quantity and longevity, and you’ll need to do a little math to figure out the best product to go for.

It’s best to strike a nice, cost-effective balance between how much you’re initially paying, the area it will cover, and how long it will last.

Summary

If you’re in any way unfamiliar with what’s available, the world of weed killing can be a daunting and complex environment.

That’s why taking a bit of time to examine each product can really help you focus on finding the best weed killer for large areas, and I hope this article has helped in some small way.

Personally, I prefer to stay away from the harsher chemicals, but I realize that might not always be possible – especially if you’ve got a lot of land and simply want to destroy everything as fast as possible.

To that end, I think the RM43 is hard to beat.

The 11 Best Pre-Emergent Weed Killers in 2026

Scotts Halts Crabgrass & Grassy Weed Preventer

It’s a surface-applied herbicide used for the control of many annual kinds of grass and broadleaf weeds in ornamental plantings, rock gardens, bulbs, and ground covers.

Just one gallon can treat between 40 and 80 thousand square feet. Best applied with a pump-sprayer and mixed with the right amount of water, this will keep just about anything unwanted from sprouting up wherever it’s applied.

Pros

Cons

RM43 Glyphosate Plus Weed Preventer

You might be wondering what RM43 is doing on this review of pre-emergent weed killers, and that’s because it works as a weed preventer as well as a spot treatment for existing growth. ANY growth – including murdering nettles.

After application, this will keep any area vegetation-free for up to one year, as well as destroying existing weeds in the process. As such, bear in mind it will kill anything green that it comes into contact with, so care should be taken around your desirable blooms.

Still, there’s not much out there that’s as potent or effective for keeping an area barren of plant life should you so choose. One gallon can treat up to 17,297 square feet, so you have a professional herbicide that is ideal if you need to control larger areas.

Pros

Cons

Tenacity Turf Herbicide

Like the RM43, Tenacity is a pre and post-emergent herbicide – which is why it’s justified its inclusion here. However, that is where the similarities end, as this is a selective herbicide that is safe for use on your turf lawns for getting rid of nuisance weeds only.

Very cost-effective, it’s used for residual control of undesirable plants in turf grasses, and will keep over 46 different broadleaf and grassy weeds away, with an active ingredient that is actually a naturally occurring compound.

It can be applied in both spring and fall for season-long control and inhibition of crabgrass and broadleaf weeds, and a little goes a very long way with this five-pound bottle.

Pros

Cons

Dimension 2EW Dithiopyr Pre-Emergent Herbicide

This specialty, professional-grade herbicide provides pre-emergent and early post-emergent control of crabgrass, as well as 45 other nuisance weedy grasses and broadleafs.

In order to achieve post-emergent control, you should be looking at using two pints of the product per acre.

How to Choose the Best Pre-Emergent Weed Killer

In this next section, you’ll find further information and advice for choosing the right pre-emergent weed killer for you.

How Pre-Emergent Herbicides Work

Pre-emergent herbicides are most often used well before plant life has germinated – either in early spring or late fall.

They work by inhibiting a key enzyme that provides an invisible barrier through which seed growth cannot pass. Effectively, a pre-emergent herbicide neutralizes a plant before it has the chance to germinate.

Some products will also contain a fertilizer to feed desirable plants or an established turfgrass at the same time.

Any seedlings that have big ideas for seeing the light of day will be terminated by this invisible film in the soil, created when a pre-emergent herbicide has been applied correctly and watered to activate.

Quantity/Coverage

How much pre-emergent herbicide you need will obviously be determined by how much land you need to cover.

As mentioned, a pre-emergent herbicide is specifically designed for distribution over a wide area, so getting the coverage you need isn’t that challenging.

Again, just make sure you’re referring to the instructions when mixing liquid formulas – as achieving the right balance of water (and surfactant – if required) can often be the trickiest part of the process.

Liquid or Granules?

Pre-emergent herbicides are available in granular or liquid form. So it comes down to choosing one of these types of weed killers.

Granules are much easier to use and usually come with a scoop of some kind to assist with their application.

However, using a dedicated spreader is better if you have a larger area to cover – but they’re always sold separately. If you don’t have access to such a device, I would recommend picking one up second-hand to save a bit of cash.

While granular pre-emergent herbicides are usually cheaper than liquid versions, you’ll get much better coverage with a liquid.

And when it comes to the effectiveness of a pre-emergent – accurate and extensive distribution is key – which is where liquid herbicides excel.

Still, it can be a bit of a challenge to get mixing quantities right – especially if you’re using a surfactant (an additional liquid product that breaks surface tension and improves herbicide absorbency).

And liquids need the right kind of applicator to do the job, usually in the form of a tank or backpack sprayer. This I would recommend purchasing brand new – so you know that no other chemical has been used in it and you’re not risking any kind of cross-contamination.

Once both versions have been applied, you need to add water to activate. This is where liquid has another advantage, in that it will take less hosing or rainfall for the herbicide to begin working its magic in the soil.

Whichever version you choose, diligently read and understand the instructions before use.

Selectivity/Targeted Weeds

When choosing any kind of weed killer or preventer, you need to be aware of its selectivity.

Herbicides can be selective, or non-selective. Selective means that they will only treat certain types of plant life. Non-selective means they will attack anything.

When it comes to pre-emergent herbicides, it’s important to learn what the chemical is going to kill, and what it’s going to leave alone – if anything.

This is particularly true if you want to apply a herbicide to your lawn. You need to make sure it’s not going to harm existing, desirable plants and grasses.

This is where having an understanding of weed types is highly beneficial. Check out the video below for an excellent guide.

Advantages and Disadvantages of Pre-Emergent Herbicides

The Pros

Naturally, as with all such chemicals, a pre-emergent herbicide comes with its pros and cons. Let’s start with the good news.

Pre-emergents stop weeds in their tracks, meaning that with proper application and at the right time, you might not see a single weed in a treated area for the length of the season.

And speaking of time, a good pre-emergent will be effective for up to one year, and no less than three months – depending on quality.

Finally, the coverage square footage of a pre-emergent herbicide is a very attractive proposition for anyone with larger yards and gardens. Applying this solution is usually much easier and faster than a post-emergent weed killer.

Once again – prevention is much better than cure. For more information, have a look at this article on when to apply weed control.

The Cons

Now for the bad news. Post-emergent herbicides are useless on already established weeds and grasses – and you’d be surprised at just how many people get this wrong and complain when it has had no effect.

(There are one or two products that incorporate both types of herbicide, however, and will kill existing weeds and then keep the treated area plant-free. Still, standard pre-emergent weed killers do not kill visible weeds.)

Also, the timing and temperature of applying pre-emergent needs to be just-so – especially for the effective treatment of crabgrass.

If you’re too late or too early in spring or fall then you won’t have effective results. Whichever product you decide to try, make sure you adhere to the directions completely.

Last but certainly not least, pre-emergent weed killers are rarely pet-friendly. It’s highly advisable you keep children and animals inside – at least until the product has been watered into the soil, and has had a chance to dry.

FAQs

What month do you put down pre-emergent?

Always refer to a particular product’s directions (as they can vary from brand to brand) for the best month to apply the formula. By and large, you’ll want to be putting down a pre-emergent in the early spring or fall.

Certain pre-emergents can be applied throughout the season, but for the most part, the barrier should be down before weeds have a chance to grow – so get in early.

It will also depend on what weed you want to target, so again, make sure you know thy enemy before charging into battle.

Choosing the right product and using it at the right time is essential for your success.

What is the best time to apply a pre-emergent weed killer?

Again, it depends on the type of weed you’re looking to control, and the pre-emergent you’re using. Always read the label.

Check out the excellent video below for advice on using a pre-emergent in the spring – which is when most gardeners will be keen to block forthcoming weeds.

What is the best soil temperature for applying a pre-emergent weed killer?

For best results, you should be applying a pre-emergent herbicide BEFORE the soil has been at a temperature of 55 degrees or above for between 36 and 72 hours.

55 degrees is like DEFCON 1. When the soil temperature goes above that number for a sustained period of time, that’s when seeds begin to germinate, weeds start to become a problem, and then you’re at war.

You can use a soil thermometer, or you can contact your local county extension service for agricultural advice and soil readings in your area.

Alternatively, use this excellent soil temperature map and locate your area.

However, you’ll find that the soil will be around this temperature from March to April for the spring application of pre-emergents.

How long does pre-emergent last?

The residual effects of a pre-emergent herbicide will depend on the particular product you’re purchasing.

Generally speaking, you’ll find they last between 3-12 months. Check the label or specifications for further details before adding to the cart.

Can you put down too much pre-emergent?

Yes – and it can be a seriously grave error if you do with potentially disastrous results.

ALWAYS make sure you adhere to the guidelines on the product label – and like any drug or medicine you might take – never exceed the stated dose.

Also, be aware that the misuse of chemicals in and around your home and property can land you in serious trouble with the law. So, be sure to read that label thoroughly.

How soon can I seed after pre-emergent?

Depending on the pre-emergent (some products you won’t be able to seed at all) you should be waiting between 7-10 days before attempting any new work.

Can I put down pre-emergent and fertilizer at the same time?

Yes, and there are products that contain both – particularly in the Preen and Scotts ranges.

Just make sure you water them both down into the soil well.

Should you mow before pre-emergent?

You don’t have to, but it is recommended that your lawn isn’t a jungle when you apply a pre-emergent herbicide. You want the product to be watered into the soil, and that will be easier to accomplish if the grass isn’t too high.

Don’t mow your lawn for a few days after application though, so you can allow the stuff to take hold.

Will rain wash away pre-emergent?

No – in fact, quite the opposite.

Unlike a post-emergent weed killer, you want it to rain after you apply a pre-emergent, because it will save you from having to water the area you’ve treated, and activate the herbicide defense barrier in the soil.

Can you put pre-emergent on wet grass?

No. It won’t be as effective.

Apply the herbicide before it’s due to rain on dry grass and soil, and then water it yourself if no rain is forecast.

Should you water after using a pre-emergent?

Yes! That is how you allow the chemical to activate and get to work protecting your soil and preventing weeds from germinating.

It’s best to add around 1/4-inch of water to the treated area once you’ve applied the herbicide.

Does pre-emergent kill existing weeds?

It depends on the product. Certain pre-emergent weed preventers also incorporate post-emergent weed killers – so they’ll kill anything they come into contact with and keep that area totally plant free for the foreseeable future.

However, by and large, pre-emergent herbicides are useless for killing already established weeds – particularly if they’re already visible through the soil or concrete.

Check out this article for the best weed killers for driveways if you need a post-emergent product that will destroy unwanted plant life where it shouldn’t be growing in the first place.

Summary

The world of herbicides is a complex one, and finding the right product and figuring out the right time for application can be a real headache.

I hope this article and review has helped you choose the best pre-emergent weed killer for your garden project, and that you have much success in keeping weeds at bay as a result.

For my lawn, I would choose the Tenacity product, and possibly the Preen Weed Preventer with plant food for around desirable foliage in landscape beds.

Happy weeding!

Just when you thought you have gotten rid of them, there they are again springing back up and bringing terror to your lawn.

And that’s not all…

It’s so hard to get rid of them because there are a lot of different kinds that vary treatment.

One of the most common ones is the dollar weed., and nope, it’s not as glamorous as having real dollars. They are pesky little weeds that can take over your lawn!

I know you don’t want that to happen, so we’re here to help you get rid of Dollar weeds that are growing on your lawn. We whipped up a complete guide so that you can identify, remove, and prevent dollar weeds from your lawn.

Let’s begin!

What is Dollar Weed?

Dollar weed, also known as pennywort, is a member of the parsley family which originated from Asia. They have rounded, bright green leaves with wavy edges and has white flowers that bloom from July up to August.

The name Dollar weed was based on its shape. Its glossy and round leaves resemble a silver dollar. They grow in moist and shady portions of the lawn, garden, or even unplanted areas.

This weed can float even on the water so they are very difficult to deal with when left uncontrolled.

They thrive in warm climates so if you’re from the southern part of the US and other temperate regions, beware!

How to Identify a Dollar Weed?

If you spot weeds in your lawn, you don’t wanna act on it just yet.

Why?

Because you want to make sure that you use the treatment or method for that specific type of weed. Some can require different treatment so you have to identify the species first.

So you already know about Dollar weeds being common to warmer regions and have a silver dollar-like appearance, but here are additional indicators to identify Dollar weeds:

Got it?

These descriptions can help you make sure that you are dealing with the right Dollar weeds. But if you’re still unsure and skeptical, you can avail yourself professional help in identifying and actually exterminating those pesky weeds.

Why are There Dollar Weeds in My Lawn?

If you found out there are dollar weeds growing in your lawn, the main culprit is too much water. And this can be caused by a number of things like over-watering, too much rain, the poor-draining quality of the soil, or the layer of grass being thin.

From these situations, dollar weeds can expect to grow rapidly and take over your lawn if you don’t act fast. This grass spreads via seeds or from the underground roots.

This means that if you want to remove them, you have to be precise in killing them all to prevent them from coming back.

Is Dollar Weed an Enemy or a Friend?

Simply put…

Dollar weeds are one of your lawn’s mortal enemies.

Just like any other weed that has ever existed, they do not pose a benefit to gardens and lawns, aside from their ability to produce oxygen. But then again, we’re talking about yards here!

If you want to make your lawn look the best it can be, with bright and healthy grass that is distributed evenly, you have to get rid of those dollar weeds!

They are very damaging to your lawn because they compete with the water and nutrients that are supposed to be for your intended plants. They decrease the yield of your plants and impede the growth of grasses.

May it is a garden of any sort of plants or a field of beautiful grass, Dollar weeds can take over space if left uncontrolled.

You don’t want that, do you?

What Kills Dollar Weeds?

Technically, weeds can be pulled by hand. You can get rid of Dollar weeds through that method, but you have to be extra precise when doing it. You have to pull it all out especially the roots because it will keep growing back.

You can do this for a small number of dollar weeds growing in your lawn but if you are dealing with a large area, this is very tedious, time-consuming, and may not even be possible executing perfectly.

During this moment, you can rely on various remedies to get rid of your dollar weeds. Not only they are easier but more efficient in killing and even preventing the weeds from coming back.

Chemical Treatment

Chemical applications are the most efficient way of dealing with weeds because they are scientifically designed for that purpose.

There are a lot of weed killers available on the market today. They are mostly grass and pet safe, so you don’t have to worry about it affecting things around you.

For only a few dollar weeds or a small patch of them, you can spot treat them using ready-to-use dollar weed killers like Roundup® For Lawns Southern Formula Ready-To-Use. These are effective in killing to the roots, so the weeds won’t grow back.

For bigger areas crawling with Dollar weeds, you can use Weed & Feed products or Herbicides.

Weed and Feed products are used to treat larger dollar weed problems. These products kill weeds, including dollar weeds of course, yet providing the lawn with nutrients, hence the feeding part. You can see these in the market are specifically labeled as weed-and-feed.

Examples of these that kill Dollar weeds are Scotts Turf Builder Bonus S Southern Weed & Feed and Scotts Turf Builder Southern Triple Action. Just read and follow the instructions written and you’re good to go!

Herbicides, on the other hand, are more specific in killing the weeds and they are widely used for this purpose.

To kill Dollar weeds fast and easily, you can use herbicides such as MSM Turf herbicide or Fahrenheit herbicide. MSM turf herbicide, when applied to your lawn, will only do its job to the weeds and will not affect your grass. It can be applied through a hand pump, hose, or backpack sprayer and can cover up to one acre of the lawn.

Meanwhile, Fahrenheit herbicide is a composition of water-soluble granules also used to kill Dollar weeds. It can also be used in large volume and area treatment, and it offers a wider variety in terms of application.

Other herbicides that are proven to get rid of Dollar weeds are Atrizine, Image (Imazaquin), 2,4-D, Blade, Manor, and Monument.

They are all safe for use in various types of grasses like Zoysia, St. Augustine, Bermuda, and Centipede grasses.

It’s only a question of choosing one of the many weed killer types available.

Here’s a simple procedure on how you can apply chemical herbicides to get rid of Dollar weeds.

Step #1: Measure the Treatment Area

Calculate the square footage where you will apply the herbicides. You can do this by multiplying the length and width of the designated space. This can help you determine the right amount of product that you should apply to the lawn.

Step #2: Mix the Herbicide Solution

Herbicides that are available in the market have their recommended mixing proportion. For example, MSM Turf Herbicide recommends .125 ounces mixed with 1 ounce of water per acre of land that will be treated. Given that you have a 1,000 square foot area, you would mix 1 oz. of MSM turf herbicide with 32 ounces of water in a hose-end sprayer.

For average applications, a 1-gallon pump would be great to easily apply the treatment.

Step #3: Apply Solution to Dollar weeds

After filling up your sprayer, you can not apply the solution to the area you want to treat. People use fan nozzles to get even coverage to the area.

Don’t water the lawn for a day to let the solution soak in and be absorbed by the weeds. You should see the changes after 14 days and in some cases, you should reapply after 3 weeks.

Things to remember:

Organic Treatment

We know that some people are very conscious of what they apply to their gardens and lawns and that’s not bad at all.

Though chemical applications are proven effective for the job, they are composed of inorganic chemicals that contribute to land and water pollution. Thus, there is a great reason for people who want natural options.

And we have just the tips for you!

These alternatives can help you get rid of Dollar weeds on your lawn without leaving traces of the chemicals. Just take note that these may or may not be effective for everyone but these are worth trying before resorting to chemicals.

There are a lot of ways to get rid of weeds without chemicals. You can always try them and see what works for you.

Can Dollar Weeds Grow Back?

Let’s say you’ve managed to get rid of Dollar weeds this time, should you still worry about them?

Well, if you’re confident that you got them all, then you shouldn’t worry about it in the near future. However, it doesn’t mean that you will not deal with them forever.

So, we also have tips for you to prevent Dollar weeds from growing back. Here are some points to remember to protect your turf from Dollar weeds.

Feed Your Lawn Properly

Feeding your lawn with the right fertilizers can make the grass grow thick and strong. This can help overtake weeds if there are a few that are starting to spring up. Feed your lawns 2 to 4 times a year to provide the right amount of nutrients.

Water Less

If Dollar weeds are your main concern, then lessening your irrigation can help you get rid of them. Since Dollar weeds are water-loving plants, you should never overwater the lawn.

Thus, you should limit your lawn’s irrigation to only an inch of water per week. This allows the soil to dry out and prevents Dollar weeds from growing and spreading further.

You can also improve the drainage of your soil by aerating it. Aerating the soil lessens water retention.

Mow High

Mowing at the right height for your specific grass helps its leaves to grow thicker and its root system to grow deeper.

To get rid of Dollar weeds in St. Augustine grass or Floratam grass, we would advise mowing the grass to about 3 to 4 inches. Mow Zoysia and Centipede grass to 2 to 3 inches while 1.5 to 2 inches for Bermuda grass.

FAQs

Why do I have so much dollar on my lawn?

One main reason as to why you have Dollar weeds on your lawn is overwatering and saturation of the soil.

Should I ask for professional help?

For a small Dollar weed problem, spot treatment can be easily done on your own.

Summary

Now you learned how to get rid of Dollar weeds. You can now identify them and plan out the best solution for your weed problem.

How to Choose the Best Post-Emergent Herbicide

Below you’ll find plenty of tips and advice to assist you in choosing the right post-emergent herbicide for you.

How Post-Emergent Herbicides Work

The clue is in the name for post-emergent herbicides, and they’re designed to work after a plant has established itself and broken through the soil.

Post-emergent herbicides work best when the unwanted vegetation is actually growing.

How it does this depends on the individual product and the active ingredient it contains. It’s not one size fits all, and there is a huge variety of herbicides that attack weeds in different ways.

Post-emergents will contain a number of different chemicals or ingredients that are designed to inhibit plants and exterminate them. For more information, read this excellent, in-depth article on how herbicides work.

Advantages and Disadvantages of Post-Emergent Herbicides

The pros and cons of post-emergent herbicides are well documented, but let’s just briefly touch on them here for simplicity’s sake.

Their greatest asset is that they are very effective at what they do – particularly when it comes to the more potent weed-killing chemicals – such as glyphosate.

Certain products will burn down a problem weed in a matter of hours, and in a couple of days, it will be stone dead. For others, it might take a few weeks – but you should still get good results eventually.

Aside from this, they are very easy to use, with a variety of application methods available depending on where, what, and how much you’re treating.

Unfortunately, that’s where the advantages stop. Post-emergent herbicides are, with some exceptions, dangerous, toxic chemicals.

These formulas can cause a detrimental impact on the environment, not to mention to the people who use them, their children, and pets.

And unintentional spread can be difficult to control – especially when treating larger areas with a tank or backpack sprayer. Even the slightest breeze or misdirected application can cause a non-selective herbicide to come into contact with desirable vegetables, plants, and blooms.

Often a necessary evil, weed killers should be handled with great caution – and by people who know exactly what they’re doing.

But have a look at this article for how to get rid of weeds in a lawn without using chemicals. I always try to encourage more natural ways whenever possible.

Quantity/Coverage

As with all weed killers, the amount you purchase will depend on how much land you need to cover, or how large your weed problem is.

If you’re treating one or two weeds, you can use a spot treatment with a trigger or weed wand. This herbicide will likely come in a ready-to-use bottle.

For larger areas, a tank/compression sprayer or hose applicator might be called for. Often, a herbicide that is distributed in this manner will come as a concentrate – and require diluting with water.

A surfactant might be required – which is an additional liquid that is added to help break the surface tension between the weed killer and the target. Surfactants help the herbicide go further and be absorbed faster.

Either way, try to purchase quantities that you know you’re going to use. Herbicides have a shelf-life – and will become ineffective and wasteful if surplus to requirements.

Application Method

As previously mentioned, post-emergent herbicides can be dispensed in a variety of ways, and they come in the form of either liquid or granules.

Granular post-emergent weed killers are applied either with a dedicated spreader or by simply shaking the bag or box of product where you require.

The best liquid post-emergent weed killers are applied either with a trigger gun, a weed wand, a hose applicator, or a tank/backpack sprayer.

The method you choose will depend on the area you’re covering, the results you’re trying to achieve, and the type of weeds you’re attempting to treat.

Selectivity/Targeted Weeds

Like pre-emergent weed killers, their post-emergent counterparts can either be selective or non-selective when it comes to the plants they are designed to target.

Selective weed killers will only attack certain plant life. They’re best used in lawn care where you don’t want a herbicide to damage your existing turf grasses, but you do need it to clear undesirable weeds.

Non-selective weed killers will go after just about anything that’s green. They’re best used when you want an area completely devoid of any kind of vegetation.

Before making your purchase, you should know the types of weeds your preferred product is or is not going to kill. All too often mistakes are made and the wrong kind of herbicide is purchased for the wrong job. And keep in mind there are many weed killer types to choose from so it’s good to know more about them.

When in doubt, check the label. All herbicides should list the plants that they will attack, so you know if you’re purchasing the right product for your needs.

And I’ve yet to see a better video than the one below to help you with weed identification.

Rainproofing and Persistence

Apart from the timing of application, perhaps the most notable difference between a pre and post-emergent herbicide is to do with how long it lasts in the soil.

It’s not always the case, but generally, a pre-emergent herbicide will last several weeks/months longer than a post-emergent.

While there are post-emergent herbicides that have lengthy residual times in the soil, for the most part, they don’t hang around. This is so you can be free to plant desirable foliage and flowers within a few days of application.

Aside from that, pre-emergent herbicides require water to be activated, whereas post-emergent herbicides will not be effective if they’re washed off their target plants.

There’s also a risk that surface run-off will carry potentially dangerous chemicals into water courses and unwanted areas.

Post-emergent weed killers, therefore, come with guidelines on when the formula will be rainproof, which could be anywhere between ten minutes to over two hours.

Either way, it’s a good idea not to apply a post-emergent herbicide if rain is forecast – just to be on the safe side.

Additionally, both pre and post-emergent weed killers need to be fully dry before they stand any chance of being pet and human friendly, so keep animals and children away until that happens.

Active Ingredients

It’s important to know and understand the active ingredient of a weed killer. This will basically inform you what is actually doing the killing – and how that killing will take place.

Different chemicals, compounds, and formulas will attack weed and plant life in different ways. Some might be root inhibitors, others might prevent the protection of chlorophyll, or affect cell membrane production.

Understand the active ingredient will also help you understand which plants the herbicide will or will not attack.

From a safety perspective, some active ingredients are more harmful to us humans than others – so care must be taken with their use.

FAQs

Is Roundup a post-emergent?

It depends on which Roundup product you’re talking about as their range is extensive and it can be a challenge to choose the right one.

While most Roundup products are post-emergent herbicides, the brand also manufactures some pre-emergent weed preventers, too.

Check to see when the product is applied for confirmation.

When should I apply post-emergent?

Again, it depends on the particular product.

Some post-emergent herbicides are best applied at a certain time of year, or in certain temperatures and soil conditions.

But they will nearly all be most effective when applied in early spring when the weed is young and growing.

Having said that, a post-emergent herbicide is designed to attack and kill weeds that have already grown and are established – so feel free to unleash the liquid death whenever you see weeds protruding from the soil.

What is the strongest post-emergent weed killer?

There are a few contenders for the crown of strongest post-emergent weed killer, but it’s really all speculative and can depend on where and what you’re treating.

Anything with a high concentration of the active ingredient is going to be pretty deadly – toxic or otherwise.

The Southern Ag, RM43, Roundup, Monterey, and Spectracide brands all have products that are extremely potent – but so do the lesser-known versions.

Head on over to this article on the best commercial weed killers if you’d like to know who the pros use, and then you can make your own mind up which is the strongest.

Sometimes, trial and error is the only way to know for sure.

Does post-emergent kill grass?

It certainly will if it’s non-selective.

Selective post-emergent herbicides are available that only attack certain weeds, thus keeping your prized lawn intact while literally weeding out the invaders.

However, the vast majority of post-emergent weed killers are non-selective and are designed to simply destroy everything green that they touch.

Double-check your labels – and always dispense with great care, regardless of what category a particular herbicide falls under.

Can I apply pre-emergent and post-emergent at the same time?

You can – there’re no restrictions placed on the timing of application between a pre or post-emergent herbicide.

However, pre-emergents are most effective when laid in the early spring, fall, or early winter, whereas post-emergents thrive from late spring to mid-fall.

Not to mention the fact that you could well be trying to use a bunch of different chemicals that can treat some weeds but not others – which would prove a waste of time and money in the long run.

Certain products are useful as both pre and post-emergent herbicides, so when treating an area you not only kill existing weeds but it will remain clear of vegetation for a given period of time after application.

I would suggest trying them before attempting to concoct your own, crazy mix.

Furthermore, depending on the chemicals involved, there are likely application limits set by law, and mixing high concentrations of pre and post-emergent weed killers might be in breach of that – depending on your state’s regulations.

For more information, have a root around on the herbicides page of the United States Environmental Protection Agency.

In short, it’s best to err on the side of caution and only use one product at a time – and when it is recommended to do so.

Again, always refer to the labels – because they are literally the law.

What is the difference between pre-emergent and post-emergent?

A pre-emergent herbicide is designed to stop weeds from germinating. It is usually applied before the temperature of the soil reaches 55 degrees in spring, but it can also be used in the fall and early winter to prevent certain grasses or weeds from arriving the following year.

A post-emergent herbicide is for when the weeds have already broken through the soil, they’re visible, invasive, and growing. Post-emergent herbicides can be applied throughout the season to spot or blanket treat nuisance weeds and vegetation.

What herbicide will kill everything?

If you absolutely, positively, want to kill everything green, then choose a non-selective herbicide with a high concentration of its active ingredient.

This is most likely to be glyphosate – the world’s most popular weed killer.

It does not discriminate –  a high percentage of this stuff will pretty much destroy any plant life in your yard or garden.

However, it’s at your own risk. Glyphosate products have been on the receiving end of some seriously negative press over the past few years.

Summary

Herbicides are a controversial topic, but many gardeners the world over still swear by them for keeping their lawns and landscapes weed-free.

While prevention is better than cure (and good garden practices can help) the best post-emergent herbicides are often a necessary evil.

I would always choose the more organic, natural option if I had to use one – in this case, the Green Gobbler product.

But to each their own – let me know which product you would choose and why. Whatever you decide, always make sure to apply it safely, with care, and in accordance with the instructions.

Best of luck and happy weeding!

You’ve heard about overseeding but you’re skeptical. And that’s fair enough!

No one wants to waste a bunch of seed, time and effort if it might not work, right?

I’m going to tell you a bit more about overseeding a lawn with weeds, whether it works and how to do it if you decide that it’s right for you.

Let’s get into it!

Key Points

What is Overseeding?

Overseeding is the practice of adding seed to an already established lawn, but one that has a few too many bare patches and/or weeds present.

Usually, you will also add a layer of compost and fertilizer at the same time to give the seeds the best possible shot.

Does Overseeding a Weedy Lawn Work?

Yes!

Overseeding a lawn with weeds does work, but there are some caveats to this. Some lawns will respond better to overseeding than others, and there are right and wrong ways to go about overseeding a weedy lawn.

It helps to understand a little about why lawns get weedy in the first place and how overseeding helps.

All plants, including both grass and weed species, need space and light to survive. A healthy lawn will be so lush and dense with the grass species that you want, that there won’t be much opportunity for weeds to arrive and establish themselves.

But, as soon as your lawn gets a little overgrown and/or bald spots appear, any weeds that might be present get an opportunity to go to seed, and any seeds arriving on the wind have an easier time finding space to get established.

What does this mean for us?

So, with this in mind, you might be wondering, will overseeding kill weeds?

Overseeding a weedy lawn doesn’t directly kill the weeds that are already present. But, if done at the right time of year, the growth of enough healthy grass will outcompete the weeds by starving them of light, space and water, and prevent more weeds from growing.

Exceptions to the Rule

While re-seeding a moderately weedy lawn with bare patches works really well most of the time, there are some weeds that are so stubborn and relentless that outcompeting probably won’t work.

A good example is crabgrass. You may have to apply some other management tactics to control your crabgrass if you have a lot of it. Luckily, there are natural ways to manage crabgrass that are a lot safer, and sometimes more effective, than relying on herbicides.

Other weeds that may require some specific attention are dollar weed and Bermuda grass (in some parts of the world, Bermuda grass is the lawn species of choice, but if its growing where you don’t want it to then it becomes a weed).

When Should I Overseed my Lawn?

The timing of overseeding can be the deciding factor in how successful it is.

Both grass and weed species have a period of the year where they are dormant and periods where they are growing.

The trick is to time your overseeding project for when grass growth is at its peak and most weed species are dormant. This may not always be completely possible as there will be some overlap, but some times of the year are definitely more optimum than others.

For most regions, late summer or early spring are the best times. However, if you have applied any non-organic fertilizers or selective herbicides designed to prevent seed germination, you’ll need to wait a while until those chemicals are no longer present.

Tips for Successfully Overseeding Your Lawn

Carry Out Some Prep Work

Rather than just jumping in and overseeding straight away. Taking a few steps beforehand can make your overseeding much more successful.

Hand pulling any really large and obvious weeds is probably a no-brainer but worth mentioning all the same. You want to create conditions that will maximize the chances of the grass seed being more successful than the weeds. So, give it a fighting chance by removing what weeds you can first.

Giving your lawn a good watering (enough to reach 6 or so inches down into the soil) a couple of days before overseeding is also good practice. If you water too much immediately after overseeding you may just drown the seeds.

Mowing your lawn really short before overseeding also gives the new seeds a good chance of success without being shaded out by existing grass. But be sure to remove the grass clippings. While leaving a fine sprinkling of grass clippings is a good practice most of the time (read this article to find out why), you don’t want any grass clippings on your lawn before overseeding.

Removing thatch is important for similar reasons. New seeds won’t have much of a chance if they have to fight through thatch first. If you’re new to dethatching, I have a how-to guide here.

Choose the Right Grass Seed

Did you know that there are many different species of grass that can make up a lawn seed mix? The species you choose will play a large role in how successful your overseeding project is.

You can also exercise some preferences depending on whether you want thin or thick blades of grass, hard-wearing for lots of foot traffic or less hard-wearing but more aesthetically pleasing, and low maintenance that doesn’t need mowing as often, or faster-growing that does require regular mowing.

In saying that, if you already have some grass seed left over, then by all means use it. There is no sense in letting it go to waste. Chances are it will still be fine to use as well. If you’re not sure, I’ve explained how to work out if grass seed is bad in this article.

How to Overseed

Last but not least, let’s explore how to actually reseed a lawn with weeds.

Assuming you’ve carried out the preparatory steps above, the main steps to overseeding are spreading compost and fertilizer, spreading the seeds, and then watering.

Applying around ½ ich of compost over your lawn will provide an easy growing medium for your seed to germinate in. There’s a chance you may have some success without doing this but your germination rate will be much lower.

Applying your own homemade compost is an excellent choice here as you can save money and you know exactly what you’re putting on your garden which is a must if you have kids and pets.

It’s also helpful to fertilize in order to make sure that all of the nutrients required for healthy grass growth are present. Organic fertilizers are superior in the long run when it comes to soil health but a one-off application of synthetic fertilizer when you overseed is not going to do any major harm.

If you’d like to learn more about the world of fertilizer,  I have some helpful articles on when and how often to fertilize, the difference between liquid and granular fertilizer, and the shelf life of different kinds of fertilizer.

The next step is to sprinkle a fine layer of seeds over your lawn. You want around 15-20 seeds per square inch and this can be made easier with the right equipment. A handheld broadcast spreader is best for regular size lawns but if you have a big area to reseed, you might choose a tow behind spreader instead.

After applying the seed, rake it into the compost a little bit and ensure its evenly spread.

Finally, give your thirsty lawn a drink with a sprinkler (or some of your own harvested rainwater if you’ve got your collection tanks set up), and then wait for the magic!

Summary

Hopefully, you’re feeling pretty knowledgeable when it comes to the ins and outs of overseeding lawn with weeds.

It’s actually not super complicated and it’s definitely the best solution to managing a weedy lawn. Simply get the timing right and with the right seed, your lawn should be well on its way to being lush and weed-free.
