Will Vinegar Kill Bermuda Grass?

Bermuda grass is a turf that can withstand drought and is used for lawns around the country. But it is also a weed that spreads quickly and takes over other grassy and groomed places. Instead of utilizing chemical-based herbicides, consider using natural vinegar to destroy Bermuda grass spots. Bermuda grass will be successfully eliminated by the vinegar, but any nearby vegetation will also perish.

To prevent the grass and other vegetation around the Bermuda grass clumps from dying, spread trash bags on the ground. To keep the bags in place, weigh down the bag edges with bricks. You can skip this step if you don’t care about harming the surrounding plants.

  • Bermuda grass is a turf that can withstand drought and is used for lawns around the country.
  • To prevent the grass and other vegetation around the Bermuda grass clumps from dying, spread trash bags on the ground.

One gallon of white vinegar and one ounce of liquid dish soap should be put in a garden sprayer.

To combine the ingredients, put the top on the garden sprayer and gently shake it back and forth. Avoid making too many soap suds.

Spray the vinegar mixture onto the Bermuda grass blades with the garden sprayer’s nozzle until it drips off. Spray any more patches of Bermuda grass by repeating the procedure.

If necessary, take away the trash bags to let sunshine reach the nearby vegetation. Wait three to five days before checking the Bermuda grass patches for evidence of recent green growth close to the base.

  • 1 gallon of white vinegar and 1 oz. should be put in a garden sprayer.
  • To combine the ingredients, put the top on the garden sprayer and gently shake it back and forth.

Pour 1 to 2 cups of the vinegar solution into the soil just beneath the Bermuda grass to kill the roots, and then reapply it to the green areas of growth.

After the Bermuda grass has completely died, you can cover the bare regions with top soil and grass seed to encourage the growth of new vegetation.

What causes Bermuda grass to die forever?

There are several strong reasons why Bermuda grass (Cynodon dactylon) is a preferred lawn grass in the drier parts of the West. It enjoys the heat, is incredibly durable, and, in terms of turf, is relatively drought tolerant.

But if you choose to replace this turf with anything different, its commendable energy also makes it difficult to remove. Bermuda grass (Cynodon dactylon) spreads via aboveground runners and underground stems (rhizomes) (stolons). It also seeds rather aggressively.

Most experts and homeowners use a herbicide (often glyphosate) to kill it because it is so hardy and persistent.

They spray, remove fading sod, irrigate to encourage growth of any rhizomes that have survived, and repeat the procedure at least once (one treatment rarely kills a Bermuda lawn).

However, there are alternatives if you don’t want to use glyphosate and the herbicide is not as safe as first thought. Three experts offer their opinions.

1. Owen Dell, a Santa Barbara-based landscaper and the author of Sustainable Landscaping for Dummies

All types of lawn, including Bermuda, can be removed using this procedure, according to Dell. The soil beneath the grass is removed, three layers of cardboard are placed over it, and then four to five inches of mulch are placed on top. He then leaves the entire area sit for six months.

But he issues a warning: Don’t think your job is done once you’ve gotten rid of the Bermuda.”

He claims that Bermuda seeds are in the air. “They’ll return, whether it takes a year or five. so watch out.

2. Cheryl Wilen, UC Statewide Integrated Pest Management Program area advisor for Los Angeles, Orange, and San Diego Counties

Not willing to wait the full six months? After removing the grass using a grass scraper, lay down strong landscaping fabric. Next, make fabric holes. If possible, keep it tiny and put it where you desire.

According to her, this approach does not work for annual and vegetable beds that are constantly changed out, but rather for plantings that are permanent such as shrub and perennial borders.

Mulch should be placed over the cloth to prevent fading from the sun. If possible, use drip irrigation to water only the regions that are planted. The remainder of your yard should remain weed-free, but you’ll need to keep an eye out for Bermuda encroachment in the cut-out sections. (The roots simply stop developing in the sections of soil that are covered.)

If you live inland, Wilen claims that covering Bermuda with clear plastic and letting the sun bake it to death can be highly effective in the summer. However, it is ineffective if you live near the shore where the summers are frequently chilly. It is also ineffective in shaded locations.

Alternatively, you may first cease watering the grass and let it turn brown. After that, cut it as short as you can and rake the clippings up. Once the turf has received one irrigation, it should be covered with thick, clear plastic and left in place for four to six weeks.

3. Karen Contreras of Urban Plantations, a San Diego-based company that specializes in ornamental edible gardens

Bermuda grass is easier for Contreras to remove when the weather has cooled and some rain has poured. She breaks up the soil by digging 4 to 6 inches. She then divides the clusters and manually pulls out the roots in order to save as much topsoil as possible. Put sod and roots on a tarp afterward to allow them dry out for a few days, then shake off the extra soil, advises Contreras, if you want to conserve even more soil.

What causes Bermuda grass to die naturally?

Using vinegar to kill weeds in bermudagrass is a natural method that works well. Use a 10% vinegar solution to spray on the weeds to get rid of them naturally.

The return of grass after vinegar?

Can Grass Regrow After Vinegar Treatment? Yes, barring grass seedlings that are younger than two weeks old. In that situation, the roots are not sufficiently established to produce new blades. The roots of broadleaf grasses will still produce new leaf blades even though they are more prone to die back to the soil.

Can vinegar compete with Roundup?

Rain produces grain. is a proverb that has been around for years that you might hear whenever two or more farmers are together and a midsummer shower appears. Although that proverb may be accurate, it’s also a fact that rain causes weeds.

Due to this year’s record-breaking rains, the landscape is full of highly robust, quickly spreading weeds. Homeowners are calling in to ask for “safe” ways to control those weeds as well. Vinegar is one product that is usually recommended for weed control in landscaping. A simple inquiry about vinegar frequently leads to a discussion on pesticides, toxins, the legality of its use, and what exactly “safer” implies.

Let’s start by stating that vinegar does, in fact, have some weed-controlling capabilities. In Ohio, there are currently three vinegar products with labels. The fact that they are labeled indicates that using them to manage pests is allowed, but only one of the three in Ohio is classified as a herbicide. Common household vinegar is neither “labeled” nor “authorized for use as a herbicide in Ohio,” which may be difficult for some people to comprehend.

In any case, when we see what happens to weeds when vinegar is applied, we see that the acetic acid in the vinegar “burns” through the wax coating on the surface of the leaves and kills those leaves. Annual weeds like foxtail, crabgrass, and ragweed may only require one application of the specified 20% acetic acid vinegar to eradicate them if they are little at the time of application. In contrast, household vinegar contains only 5% acetic acid. It can require more than one application if the annuals get larger before the treatment. It should be noted that when vinegar is sprayed on perpetual weeds like ground ivy, the leaves may burn and the plant will probably develop new leaves. Although vinegar can ‘manage’ perennial weeds, it seldom kills them.

We have already discussed vinegar’s acetic “acid” and the plants it “kills” in previous discussions. It’s vital to note that a product certainly has harmful effects if it kills a plant—in this example, what some would term a “natural” herbicide like vinegar! So, is it safe, or can it be “safer” than a commercial herbicide made from synthetic materials? I’ll let you make that decision as we go.

We must comprehend toxicity while we reflect on that query. The Environmental Protection Agency (EPA) undertakes research to ascertain the toxicity, or Lethal Dosage (LD50) Values, of all pesticides and many other goods we frequently use, including what many people prefer to refer to as “natural” things like vinegar. The benchmark test for acute toxicity used to compare all the evaluated goods is called an LD50. The LD50 is expressed as the individual dose necessary to kill 50% of a population of test animals and is expressed in milligrams (mg) of pesticide per kilogram (kg) of body weight (e.g., rats, fish, mice, cockroaches).

Most people who inquire about using vinegar as a herbicide want to know how it compares to glyphosate, which is frequently marketed under the trade name Roundup. EPA tested glyphosate, just like it does with all pesticides, and assigned it an LD50 value. Similarly, the EPA tested and assigned an LD50 to acetic acid, which is exactly the same as the acid found in vinegar. The LD50 values for glyphosate and acetic acid, respectively, were 5600 and 3310 when rats were the test subjects.

An LD50 figure tells us how much of an individual dose is needed to kill 50% of the test population, and the lower the number, the more deadly the substance is. In a lab test, acetic acid killed rats more quickly than glyphosate did when administered orally in identical amounts. Even common vinegar was more hazardous than Roundup due of its acetic acid content.

Going one step further, it is irrelevant to compare application rates in this situation. Most annual weeds indicated on the label can be killed with a 1% solution of glyphosate, as can most perennial weeds. The annual weeds we find in the landscape may require more than one application of a 20% acetic acid product in order to completely eradicate them.

This discussion does not imply that vinegar is a bad herbicide. The goal is to raise awareness that a substance is toxic whether it is considered “natural” or synthetically produced, as long as it has the power to kill plants or insects. Each poison should be handled carefully, used for the intended purpose specified on the label, and applied at the rate deemed to be acceptable. Both organic and synthetic herbicides can be secure and efficient when handled appropriately.

Will vinegar truly kill grass forever?

Apply a liberal amount of salt-and-vinegar weed killer just to the weeds’ leaves. Due to the saturation of the soil, neither weeds nor anything else will be able to grow there as the addition of acid and salt to the soil around the plants would kill the nutrients necessary for plant life. Consider hand weeding or hiring a professional if you find yourself continually spraying the same patch of a garden.

Use a spray bottle with an adjustable nozzle that sprays a steady stream instead of a mist.

Since vinegar and salt are nonselective desiccants, they are unable to determine which plants should be killed or preserved. Concrete and various metals can both become discolored or eroded by this solution. Applying vinegar as a weed killer is best done with a spray bottle set to a stream rather than a broad spray so that the solution lands exactly where you want it to. Many bottles have a nozzle that can be adjusted to sharpen the stream, making it simpler to spray leaves (rather than dirt) or squeeze between pavers. To avoid the solution blowing in the wrong direction, schedule the application for a day when there won’t be any wind.

Always spray your weeds on a sunny day; any rain will flush out the solution, and you will have to reapply the solution to the weed growth.

The acid’s potency will be increased by the sun and heat, and the salt’s dehydrating effects will be amplified. It will work more quickly if you apply this weed killer early on a day that is expected to be warm and sunny. While many commercial weed killers make the claim that they will remain on weeds even in the presence of rain, a vinegar-and-salt solution lacks the additional chemicals and will be washed away by rain. Therefore, if a surprise shower occurs, prepare to reapply the solution after it rains.

The vinegar-and-salt solution likely won’t prevent weeds from growing as it doesn’t reach the weed’s roots.

Although vinegar alone is not a permanent cure for all weed regeneration, vinegar works better when combined with salt to inhibit weed regrowth. Regrowth may eventually happen even with the salt applied because the foliage will probably perish before the root system dries out completely. Even with commercial weed killers, the soil is full with weed seeds that can only be completely eliminated by soaking the soil in the solution, which damages the soil’s ability to support future growth. If weeds are destroying your garden and this do-it-yourself solution isn’t working, a professional will be able to solve the problem and help you keep your garden looking lovely.

Is Bermuda grass something that can be gotten rid of?

Herbicide spraying is one of the quickest and most hazardous techniques to eradicate Bermuda grass. Use a herbicide containing glyphosate for the best outcomes because it often leaves the fewest residual effects, which is crucial if you wish to grow plants there. Wait until the Bermuda grass is about 6 inches tall so that it has adequate surface area to readily absorb the herbicide. After watering the grass as usual, spray it with a herbicide in accordance with the manufacturer’s instructions as each brand’s toxicity and potency is different. As an illustration, combine 3 ounces of the herbicide with 1 gallon of water when using Scotts’ Roundup Weed & Grass Killer Concentrate Plus, which contains the chemical glyphosate. Spray it evenly on all of the exposed grass’s surfaces after that until it is damp but not dripping.

How do you get rid of Bermuda grass in the wild?

Cover the grass with a barrier to keep it from completing photosynthesis. Bermuda grass cannot be effectively suppressed by simple mulch. I successfully employed sheet mulching in my yard with the long-term goal of finishing my entire yard gradually.


  • The grass should be cut as short as possible, ideally to the ground, or (better yet) weed-eaten. Rake up any grass, rhizomes, or stolons after that.
  • Place a layer of compost a half-inch thick over the entire area. The biological process will be stimulated.
  • Boxes should be flattened and kept together so that they are two layers thick. Boxes for appliances work well.
  • Cover the entire area with cardboard, making sure to overlap the box sides by at least 6 inches to prevent grass from growing through.
  • To help stop grass from penetrating the cardboard, secure it with a lot of Sod Staples.
  • It’s crucial to completely soak the cardboard throughout.
  • Add three inches of mulch to the area.
  • Bermuda grass should not be allowed to grow on top of mulch. Eat it back with weed.
  • For planting purposes, do not cut holes in cardboard since Bermuda grass may grow there.
  • If a sprout emerges, pull it out right away.
  • Be sure to wait at least 46 months before you disturb the area.
  • Consider transplanting already-planted plants to a temporary bed while doing this to sections that have already been planted. If not, Bermuda grass will probably flourish at the base of the current plants and spread back into your garden bed.
