The Best Way to Kill Bermuda Grass with Vinegar

Bermuda grass is a drought-tolerant turf that is used for lawns in many areas of the United States. However, it is also an invasive weed which spreads rapidly and invades other grass and landscaped areas. If you have patches of Bermuda grass you want to kill, try using natural vinegar instead of chemical-based herbicides. The vinegar will effectively eradicate the Bermuda grass, but it will also kill any surrounding vegetation as well.

Trash bags

Bricks

Garden sprayer

White vinegar

Dish soap

Lay trash bags on the ground around the clumps of Bermuda grass to protect the surrounding grass and vegetation from being killed. Weigh down the edges of the bags with bricks to keep them in place. If you do not care about killing the other vegetation, you can skip this step.

Fill a garden sprayer with 1 gallon of white vinegar and 1 oz. of liquid dish soap.

Place the top on the garden sprayer and rock it back-and-forth gently to mix the ingredients. Try not to create too many soap suds.

Point the nozzle of the garden sprayer at the area of Bermuda grass and spray the vinegar mixture onto the blades until it drips off. Repeat the process to spray any additional areas of Bermuda grass.

Remove the trash bags, if applicable, to allow sunlight to reach the surrounding grass. Wait three to five days and examine the areas of Bermuda grass for signs of new green growth near the base.

Reapply the vinegar solution to the green areas of growth and then pour 1 to 2 cups of the solution into the soil directly under the Bermuda grass to kill the roots.

Once the Bermuda grass is completely dead, you can spread top soil and grass seed on top of the areas to grow grass in the bare spots.
