How to Choose the Best Weed Killer for Driveways

Weeds in driveway

With almost as many weed killer products flooding the market as there are weeds taking over your driveway, it can be a real challenge choosing the right one.

Read on for more information about what to look for when selecting the best weed killer for your needs.

Active Ingredients and Brand Names

Depending on the type of weed or plant you want to kill or target, herbicides come with different active ingredients to get the job done.

Before making your purchase of weed killer, you should know what the product contains, and if it will be successful in destroying the particular species of weed you’re trying to deal with.

Or in destroying everything else.

To help with the jargon-busting, all these scientific-sounding chemicals have brand names, and you should familiarize yourself with the commercially available versions so you know which is which.

While it would take several pages to include them all, take a look at this very useful document that lists the main herbicides, their trade names, and target weed species.

Note that the list isn’t exhaustive.

Selectivity

The ingredient’s selectivity is also very important to take into consideration, so you understand which plants it will or will not affect.

This could be the difference between leaving a rampant patch of crabgrass totally unscathed while murdering your prized cauliflowers.

Selective herbicides control certain plants without having any impact on others. These herbicides are best used when you need to target foliage close to desired vegetation.

Non-selective herbicides will attack any plant life they come into contact with. They are more suitable for clearing larger areas where you don’t need to be so precise.

Method of Application

You should also be considering how the weed killer is going to be applied and then purchase the correct product as a result.

You’ll have a series of options that I’ve outlined below.

Ready-to-use trigger applicator – a gun-style spray bottle that contains weed killer that doesn’t need to be mixed, and can be applied directly onto the leaf.

Ready-to-use battery-powered spray – the bottle comes with its own spray attachment that contains batteries. You remove a plastic guard to activate the power cells to use the product.

Ready-to-use pump applicator – a larger container for wider coverage that you manually pump to spray the liquid where required.

Concentrate – a more potent concoction of the weed killer that can be used neat for extra strength, or diluted with water for larger areas and more coverage.

Granules – weed killer in powder or granule form that can be applied directly and/or then activated by dousing the area in water.

Special applicators are sold separately, so you can simply purchase a refill bottle of product for use with a separate applicator.

How and when you apply a weed killer will greatly affect how successful it will be.

Timing of Application/Emergence

Hands with gloves holding weeds

Herbicides can generally be applied at three distinct times throughout the emergence of unwanted vegetation.

Preplant herbicides are applied to the soil before planting any desirable crop. They are non-selective and designed to kill weeds before they grow. Prevention is better than cure, but not always possible with existing paved driveways.

Pre-emergent herbicides are applied before germination – before the weed seedlings appear through the soil surface. They’re designed to kill weeds as they grow.

Post-emergent herbicides are applied directly to the leaves of the unwanted vegetation after they have appeared through the soil. They make their way through the plant to kill it at the root.

The type weed killer you select when it comes to emergence will depend on the type of weeds you’re dealing with and where.

For the most part, the best weed killers for driveways will be post-emergent herbicides, as the weeds will likely already have sprouted through the cracks.

Quantity

Driveways are usually quite large areas, so depending on the size of your weed problem, you should purchase the right quantity of weed killer to do the job.

If you just have one or two growths peaking up through the surface, consider a ready-to-use trigger product for quick and easy, targeted application.

Whereas if you’re being overrun by nature, look into getting a concentrate, so you can mix it with water for large coverage.

Remember that there is a high chance weeds will come back, so it’s well worth having a stock of weed killing products available as and when it’s required.

Persistence/Residual Activity

Another important factor to consider when selecting your chosen weed killer is its persistence – how long it’s going to remain active for in the soil.

A herbicide that has low residual activity (if it is neutralized within a few months) is ideal if you would like to eventually plant a desired crop in the area, or encourage wanted growth.

Herbicides with high residual activity (long-lasting formulas designed to keep the area vegetation-free for up to a year) are more suitable for areas where you don’t want anything coming back.

For driveways, therefore, herbicides with a high residual activity/persistence are recommended.

However, be careful if you have a gravel driveway, as herbicides with a high persistence can easily get washed into areas of desired plants when it rains.

FAQs

Frequently asked questions

What is a weed killer?

In this context, a weed killer is a commercially available herbicide that is designed to destroy unwanted plant growth on and around your home.

They vary in strength, persistence, and application timing – so these factors should be taking into consideration before choosing the product that’s right for you.

How do I permanently get rid of weeds on my driveway?

There are a number of ways to accomplish this, and it’s often best to try several tactics for the best results.

Treating the area with herbicides, manually pulling up the weeds, and filling in any gaps or cracks will all help in your battle to control weeds in your driveway.

Check out the video below for some great advice on how to keep weeds from returning in sidewalks and driveway cracks.

Will straight vinegar kill weeds?

Unless it’s a specially formulated concentrated vinegar – no, it won’t kill weeds. They will just end up shriveling a little.

For better results, you need to use something stronger.

Will bleach kill weeds in my driveway?

Perhaps smaller weeds, yes, but for anything particularly intrusive or larger, invasive species its effect will be negligible and you will quite literally be pouring money down the drain.

How do I get rid of weeds in my gravel driveway?

You need a fast-acting weed killer that contains glyphosate to attack the weed at the root – but with a shorter persistence (it doesn’t remain in the soil for longer than a couple of months).

Alternately, if you don’t want to use a chemical, you can weed the area by hand – just make sure you dig them right up from the roots.

Or, you could resort to using one of the best commercial weed eaters – if you’re happy just trimming them back every so often.

And check out this post on edgers vs trimmers to see which one might be right for you in the battle to keep nature at bay.

How do I get rid of weeds in my driveway naturally?

As mentioned above, you could weed the area by hand – which is really the only effective natural way to get rid of weeds on your driveway.

You might try any one of the several concoctions of household items that are out there (recipes are plentiful on the internet) and they all have varying degrees of success – but by and large, they don’t work and manual removal is the best way.

You might find some more advice in this article on lawn care without chemicals if you’re dead set on not using anything harsh on your driveway.

How often do I need to apply the weed killer for driveways?

It depends on the type of weed killer and the weeds you’re trying to kill.

Some can be particularly stubborn and require repeat applications. It will also depend on how potent you make your weed killer if you’re mixing it with water.

Always refer to the manufacturer’s instructions to get the best possible result in the shortest amount of time with the fewest applications.

And research the type of weeds if you really want to arm yourself with the best knowledge in how to defeat them.

Check out this article if you’re struggling with Bermuda grass for example – which can be a real nuisance around the home where it’s unwanted.

What safety precautions should I take for using weed killers?

Grass with weeds

Whenever using chemicals of any kind you should always take safety precautions. This is especially true when dispensing herbicides.

First, never apply the weed killer during windy or rainy weather. Always wait for a warm, clear day to avoid the chemical from traveling to unwanted areas.

I would recommend wearing good quality gloves for the project. You could try a pair of these great landscaping gloves which are ideal for multi-use gardening purposes around your property.

However, for stronger chemicals, it might be wise to look at more heavy-duty protection.

Keep yourself covered up with a long-sleeved shirt and pants. Wear close-toed shoes when using any chemicals.

I would seriously consider eye and respiratory protection, too. While it might seem like overkill for spraying a lone dandelion, if you’re using a tank system or covering large areas it’s better to be safe than sorry.

Especially if you’re using anything that’s particularly potent, and at the end of the day – the smell can be awful.

Finally, always make sure children and pets are kept well away for the whole weed-killing process.

What is the best weed killer for stone driveways?

I would say that all the weed killers in this review are perfectly suitable for use on your stone driveway, but finding the best one might be down to a bit of trial and error.

It will come down to the type of weeds you’re trying to kill and the area you’re covering. In some cases, the best weed killer might simply be yourself with a weeding trowel or hook.

Read through the reviews carefully, and you should find the perfect solution for you.

Summary

I hope this article has gone some way to helping you find the best weed killer for driveways that will suit your needs.

It’s certainly a saturated market and choosing the right one isn’t a straightforward as you might think.

Personally, I’d like to try the Green Gobbler. For weeds, that is.

I like the fact that it’s non-toxic and safe to use, it’s value for money and appears to have a lot of solid reviews confirming that it works.

And it’s certainly a nice alternative to anything that could turn into a potential lawsuit.

Let me know which product you would choose and why.

Happy weed killing!
