Bermuda grass (Cynodon dactylon) is an excellent meadow grass, but it can turn your yard into pastureland if not controlled. It is a drought-resistant turf that can withstand heavy foot traffic. Hence, it is the best choice for parks, playgrounds, and gardens that see a lot of foot traffic.

However, Bermuda grass has absolutely no respect for borders and can quickly become out of control and take over your entire garden. In such a scenario killing Bermuda Grass is the only option left.

Bermuda grass can be killed in several ways, including choking, solarization, treating with selective herbicides, etc. However, depending on the severity of the Bermuda grass infestation, you should choose the most appropriate eradication method.


In this post, we will shed light on all the possible ways that can be employed to get rid of Bermuda grass. However, before you apply any treatments to kill Bermuda grass, you must remember that “Bermuda grass is evil and will tend to come back even after applying the toughest herbicide.”

Let us shed some light on understanding what exactly Bermuda grass is.

Bermuda grass, also known as Cynodon dactylon, is a warm-weather turf grass native to Africa. Because of its tenacity and ability to withstand heavy foot traffic, it could be seen all over the United States. This characteristic, however, works in favor of this grass when trampling it. You can be confident that its dogged roots are strong enough to support this grass’s rapid growth.

Bermuda grass thrives in every corner of your yard, recovering at an incredible rate and invading even your sidewalks and parking lots. As a result, Bermuda grass in your yard could be as scary as possible.

Killing Bermuda Grass: 6 Best Ways

Bermuda grass has a nice image. However, its lush appearance can be deceiving because, if not controlled, it can take on the characteristics of an invasive weed. So, here are our top recommendations for killing Bermuda grass in your yard. We have provided both natural and chemical solutions for your convenience. Depending on the infestation, surrounding vegetation, climate, and resources, you can use any method you want.

Solarization

Solarization is the first step to be mentioned. It is a technique for killing Bermuda grass by heating it. But isn’t Bermuda grass tolerant to heat? Yes, it is, but only for moderate heat. So, as a result, if you could create an extremely hot environment, you could effectively kill this lush invasive grass.

It is a simple method, although time-consuming, where you would simply cover your grass area with a plastic sheet and secure the sides with rocks. This method uses solar energy to heat and burns the Bermuda grass, including the stolon that helps the grass spread.

This is a safe method unless you have your grass grown with vegetation at the center. So, solarization is not a good idea in a densely planted area.

Note: Solarization is only possible during the hotter months when the sun is shining brightly without any barriers. In tropical areas, a white plastic cover is preferable to allow sunlight to pass through to the ground. In colder climates, black plastic covers are useful for trapping the sun’s heat for an extended period.

Pro-Tip: Mow the grass before covering it with the plastic sheet.

Choking

Choke to death the grass! Doesn’t that sound cruel? However, it is effective when dealing with a Bermuda grass invasion in your yard.

The best way to kill this grass is to prevent it from photosynthesizing, limiting its ability to grow and spread. Covering Bermuda grass with mulch is one of the most effective methods to choke it. This can be accomplished in two ways: covering the area with landscaping fabric or using cardboard pieces.

Landscape Fabric

  • Spread landscape fabric over the infested grass area.
  • Make a few holes to allow your cultivated grass to grow through.
  • Pour a layer of mulch, such as wood chips, wood bark, sand, or even gravel, over the fabric to keep it in place and press it against the ground.
  • Secure the landscape fabric’s edges so that no Bermuda grass escapes and spreads in the surrounding area.

Note: Mulching would help the desired grass and plants thrive and obtain nutrition. Mow your lawn before laying down landscape fabric. And you should keep the covering on for at least 2-3 months to prevent Bermuda grass from growing.

Using Cardboard

  • Mow the lawn as short as possible.
  • Remove any remaining taproot, tubers, or reeds.
  • Spread at least half-inch layer of compost over the entire area.
  • Deflate and pile cardboard boxes to create a two-layer thick structure.
  • Cover the entire area with cardboard, interlocking the flattened box edges.
  • Use sod staples to secure the entire arrangement to the ground.
  • Make the cardboard pieces wet.
  • Cover the cardboard with at least 3 inches of mulch.
  • Weed it back to prevent Bermuda grass from growing on the mulch.
  • Maintain the arrangement for 4-6 months.

Note: If you use this method in an already cultivated area, remove the existing plants first. This will eliminate the possibility of Bermuda grass growing at the bottom of the existing plants.

Cultivation

The good news is that Bermuda grass does not tolerate high temperatures. As a result, cultivating Bermuda grass during the warmer months could be an excellent way to prevent its spread. Digging out your yard to a depth of about four to six inches is required for this method.

Cultivating Bermuda grass aids in the removal of its roots and stolons, allowing them to dry out and die. Repeat the process every 15 days until all Bermuda grassroots and stolon have been eliminated.

Manually Removal

If you don’t want to wait months to get the results of Bermuda grass removal methods, consider manually removing them. It is time-consuming, but the results are immediate. However, this method is only feasible if there is a low level of infestation in a smaller area.

Dig out the area where there is Bermuda grass with a shovel. You can also pull the grass out with your hands. Bermuda grass grows horizontally into the soil rather than vertically. As a result, uprooting them is relatively simple. This method is most effective after the rainfall when the soil is still moist.

Chemical/ Artificial Ways to Kill Bermuda Grass

Consider adopting chemical or artificial weed removal methods if you have an intensified Bermuda grass infestation.

1. Bermuda Grass Killer

The best and most effective way to deter Bermuda grass aggression is to spray a chemical herbicide over the infested area. Herbicides are available in different formulations. However, to get the best results, it is always a good idea to use a systematic herbicide.

Roundup is one of the best formulas to use because it contains an active ingredient- glyphosate- a potent weed killer. However, the roundup is a broad-spectrum herbicide that is strong enough to kill the surrounding plants. To put it in other words, this is a non-selective weed killer that should only be used if there are no healthy plants or vegetation nearby.

Still, to get the best results, apply this broad-spectrum herbicide between spring and fall.

2. Using Vinegar

Vinegar is available in almost every household that has a kitchen!

This chemical can be used to prevent the spread of Bermuda grass. However, vinegar, like non-selective herbicides, is likely to kill the surrounding plants and the grass. So, use it as a spot treatment or if you don’t want to save any of your healthy plants.

Combine 1 gallon of vinegar and 1 oz. of liquid dishwashing soap in a spray bottle. Rock the bottle to mix the ingredients thoroughly. Spray the mixture into the infected area. Aim for the blades rather than the roots.

Reapply the vinegar solution generously to the green areas. You can also pour 1 to 2 cups of the solution into the soil directly to kill the grassroots.

Before delving into the various methods for eliminating Bermuda grass, let us first look at the factors that influence the best eradication method. Getting rid of invading Bermuda grass once and for all is every gardener’s dream project. However, you can only expect the killing approach to work under certain conditions. So let’s take a look at them.

1. Level of Infestation

Your killing approach should highly depend on your yard’s level of infestation. Not all methods work perfectly in every scenario. Certain intensified methods work best with maximum infestation while working best on the minimum spread.

2. Surrounding Plants

You wouldn’t want to harm the nearby plants and vegetation while trying to eradicate Bermuda grass. Using unhealthy methods may cause more harm than good. If the infestation is near healthy plant beds, you should impose some restrictions. Never use a herbicide (like Compare-N-Save Herbicide) that works erratically and may kill your plants and Bermuda grass.

3. Next Batch of Planting

Before using any grass-killing method, make some long-term plans. You would not want to contaminate the soil and render it infertile for your next crop of plants.

4. Resources Available

This could be at the root of everything. First, you must understand that killing Bermuda grass is not a one-time event. Methods need to be applied and reapplied to ensure the complete eradication of Bermuda grass weed from your yard. Hence, you should calculate the time and money you need to kill Bermuda grass.

Bermuda grass is a survivor. It persists even after intensive herbicide applications and is likely to reappear even after 5 years of complete eradication. This brings up the question, is it even possible to eradicate Bermuda grass once and for all?

The answer to this question is dependent on several factors-

  • The magnitude of the infestation
  • The grass growth zone
  • Time and effort were put into its abolition
  • Crops grown on the spot later, and so on.

If you’re trying to get rid of this grass in your yard, keep the following tips in mind:

  • It is extremely difficult to eradicate Bermuda grass weed.
  • You must be watchful.
  • It takes longer than you might think to eradicate this invasive weed.
  • In severe infestations, it may be IMPOSSIBLE to eradicate Bermuda grass.
