Bermuda grass is a type of drought-resistant grass that is often referred to as turf grass. However, some gardeners might prefer a different type of grass in their yard and need to kill the existing Bermuda grass. Bermuda grass grows in full sunlight without much rain. Bermuda grass is typically grown for golf courses and sporting fields, but Bermuda grass seed might travel into your yard and need to be eliminated. The grass will begin turning brown during the first decline in temperature, which is why it is usually grown the Southern regions of the United States.
Let the Bermuda grass get as dry as possible. Bermuda grass cannot survive without water, but it helps to make sure that it's especially dry before you begin to kill it. Try to start the process during a hot and dry period during the middle of summer.
Kill the grass naturally by tilling the land no more than 4 inches deep. Make sure that you uproot the rhizomes, or roots, of the Bermuda grass. Make sure that no moisture comes into contact with the Bermuda grass during this time.
Reduce the temperature around the Bermuda grass by putting a black plastic sheet over the grass. You can purchase such black tarps at your local garden store. Make sure you secure the tarp using plastic stakes so that you keep all of the grass covered.
Use post-emergent herbicide if the grass has not completely died or rotted out. The herbicide should contain sethoxydim, fluazifop or clethodim. Apply the herbicide all around the grass without affecting garden flowers or vegetables.
Apply pre-emergent herbicide the next year as soon as early spring to keep treating the grass so it is fully eliminated. After one week of applying the herbicide you should start planting your new grass seeds for new grass to begin to grow.
