Bermuda grass can be a blessing or a curse. It is beneficial for low-maintenance grassy areas such as golf courses or parks, but on regular landscapes some homeowners see it as a weed that is difficult to control and eliminate. Bermuda grass can be killed either manually or with chemical sprays; choose the manual method if you do not want to risk harming your soil.
Increase the shade over the Bermuda grass. Cover the area with a black polyethylene tarp or mow the grass at three to four inches so the blades shade themselves. The tarp is more distracting but absorbs the energy from the sun, causing the Bermuda grass roots to decay.
Tturn off your irrigation systems or cease watering for two to three weeks.
Loosen up the top six inches of soil where the Bermuda grass is growing, using a tiller. This will uproot the rhizomes, drying them out on the surface. Repeatedly sift and turn the soil to remove all rocks, grass clumps and roots. Use a rake for a finer way to sift through the soil.
Separate the loose soil from any of the grass as best you can so you can keep the same soil in your yard.
