How to Choose the Best Weed Killer for Bermuda Grass

Attempting to kill off Bermuda grass is a tricky endeavor and you’ll need to be armed with the right weed killer in order to be successful.

Below you’ll find things you need to be looking out for when it comes to purchasing the best liquid weed killer for Bermuda grass.

Pre/Post Emergent Herbicides

Herbicides fall into a number of different categories – which I will explain here.

A pre-emergent herbicide will attack and kill weeds as they germinate from their seeds. It will do nothing to existing growth.

It does this by effectively putting a barrier in the soil to stop the seeds from sprouting. However, should this barrier be broken in any way (such as digging up the soil) then the effectiveness of the herbicide could be diminished.

A post-emergent herbicide is for use on weeds that already exist on and around your property. While they are lethal to existing growth, they will do nothing to prevent new weeds from sprouting.

There are some products that attempt to combine the two – with varying degrees of success – but for the most part you should be selecting the right one for the job.

Selective/Non-selective Herbicides

Weed killers also fall into either being selective or non-selective. Knowing the difference is especially important when treating weeds in and around desirable plants, trees, grasses, and crops.

Selective herbicides will only kill certain plants and leave others alone. Check to see which species will be affected with this type of product before making your purchase.

You’ll find that selective herbicides are mostly used for spot-treating weeds in lawn care – where you want to kill the weed, but not the surrounding lawn.

Top tip – if you want to kill lawn weeds without harsh chemicals – check out that article for more information.

Non-selective herbicides will kill or damage any plant life they come into contact with. They’re utilized more for large areas where no vegetation of any kind is desired.

For Bermuda grass, you’ll find both categories are available, and it will depend on where the problem grass is located that will determine which product you choose.

Systemic/Contact Herbicides

Two more categories that weed killers fall into.

Contact herbicides will start to kill the weed as soon as the product is applied to the area that requires treating. They will only kill the sprayed part of the plant – and not to the root. The weed is likely to grow back eventually.

The advantage here is that they’re very fast-acting and you’ll see quick results.

Systemic herbicides are fully absorbed by the plant and will travel into the root system via the leaves – totally killing it stone dead. The weed won’t grow back, but it might take a bit more time to perish.

For Bermuda grass, ideally, you want a systemic herbicide as it’s a tough sucker that will keep coming back unless you’re particularly harsh on it.

You want to kill Bermuda grass right to the root – otherwise, you’ll never get rid of it.


There’s a lot of commotion (certainly in the US) in the horticultural world at present with the potential banning of glyphosate – the active ingredient many leading brand herbicides, and perhaps the most popular chemical formula when it comes to eradicating weeds.

It’s still widely available – but for how long remains unclear. Certainly, in many places in Europe, it is outlawed.

So, it’s up to you if you swear by it and want to keep using the stuff – it is still one of the most effective ways to control weeds.

Having said that, non-toxic weed killers are improving all the time and there are excellent alternatives out there.

Consider where you’re going to be using the herbicide, if you have children and/or pets around, and if you really do need to get rid of your weeds with harsh chemicals.

Personally, I’d always lean towards the environmentally friendly option if it can be helped at all.

Quantity and Application

Of course, you should also understand just how much of the stuff you’re going to need to get the job done – and how it’s going to be applied.

Ready-to-apply products usually come with a trigger applicator, or with a spray system as part of the product bottle.

In other cases – such as with concentrated formulas – you need to mix with water and apply with a pump tank or similar spray dispenser.

Just make sure you have the right quantity and applicator – you don’t want to overdo it, or risk getting herbicides anywhere they’re unwanted.

Top tip – as obvious as it sounds, thoroughly checking a herbicide label is essential to achieving the best results in the safest way possible.

Know the ingredients, understand what they’re used for, understand what they’re not used for, and the type of weed killer it is.

Trust me – you’ll save yourself time, effort, money, and a big headache.

What is Bermuda grass?

Cynodon dactylon, to give it its scientific name, is more commonly known as Bermuda grass (amongst other monikers – including crabgrass).

A native to the eastern hemisphere, it’s known for its aggressive nature, ability to withstand heat, and deep root system.

It’s difficult to eradicate and harm, is fast-growing, and is to be found thriving in hotter climates. As such, it can often be used on golf courses or on other sports playing surfaces.

However, it’s not wanted by everyone – hence the reason behind this article.

What is the best herbicide to kill Bermuda grass?

It depends on a lot of variables, most of which have been covered above in the buyer’s guide.

How aggressive is the grass? How much area does it cover? Is it located near desired plants and/or crops?

The best herbicide for killing Bermuda grass can vary – but sometimes it can just come down to trial and error trying out different types of weed killers.

How deep are the roots of Bermuda grass?

Deep. Bermuda grass roots can grow to a depth of six feet – and possibly more – depending on the soil and conditions.

Most of the root system is found in the top six-inches of soil, (around 80% of the weed) and the grass is a creeper, staying close to the ground like a dense, grassy mat.

It thrives in sun, but regresses in shade.

Will vinegar kill Bermuda grass?

If you use industrial-strength vinegar there’s a very good chance it will kill Bermuda grass.

You can make a solution at home (recipes all over the internet) but it’s just not going to be anywhere near as strong as a professionally-concocted formula.

Remember – the vinegar in such a weed killer is going to be many times stronger than the stuff you find in your kitchen at home – and as a non-selective, it will also kill any plant life it comes into contact with – so use with caution.

However, depending on the product – it might not kill right to the root – so take that into consideration.

Does pre-emergent herbicide kill Bermuda grass?

If you find a pre-emergent herbicide that controls crabgrass then yes, you will be able to kill Bermuda grass with this method.

Apply through September, October and November on your soil for the best results.

Will baking soda kill Bermuda grass?

Baking soda isn’t the best weed killing alternative out there and it has mixed results. It may or may not kill your Bermuda grass, and it may or may not kill desired plants and the lawn you actually want to protect.

The best way to use baking soda is to form a protective barrier along flower beds or the lawn edge.

Having said that, you might find good results, especially if used in tandem with a vinegar solution. It keeps the use of harsh chemicals down, too.

Will Roundup kill Bermuda grass?

It most certainly will – and anything else it comes into contact with.

Glyphosate is the active ingredient in Roundup – which is why you might have seen the brand name in the news.

This stuff will certainly destroy all the weeds you need it to – but it’s a very harsh chemical and should be treated with great care.

And don’t forget to wear a pair of good-quality gardening gloves when you’re doing any kind of manual work in your garden or yard – especially when handling chemicals.


Bermuda grass can be both an effective, durable lawn, and a challenging, aggressive weed. How you view it really depends on your location and needs.

If you’re looking for the best weed killer for Bermuda grass, however, you’ve come to the right place. Let me know which method you would like to try and why.

I would personally start with a non-toxic vinegar compound and work my way to a harsher chemical formula if absolutely necessary.

Or try one of these best commercial weed eaters if you just want to trim the stuff back and keep toxins out of your soil and watercourses.

It is our duty to protect our environment, so we can continue to enjoy it (even if you’re killing some weeds in the process).

Good luck!
