Bermuda grass (Cynodon dactylon), native to Africa, adapts well to hot, dry regions. Bermuda grass goes dormant as soon as temperatures dip in the fall, and doesn't green up again until the following spring. For this reason, many homeowners decide to remove their Bermuda grass lawn and plant something that will remain green all year. Removing Bermuda grass is challenging; it sends out runners and seeds readily. Non-specific herbicides will do the trick but it may take several applications. Apply the herbicide in spring or summer.
Care for the Bermuda grass as if you were going to keep it. Water it as you normally do and apply 1 lb. of nitrogen for every 1,000 square feet of Bermuda grass. The grass should be healthy and growing prior to applying the herbicide.
Spray the grass with the herbicide, following package directions, until it is completely saturated. Do not water the Bermuda grass after application.
Water the Bermuda grass, to a depth of 4 inches, the day after the herbicide application and water normally for 10 days.
Reapply the herbicide in the same manner as you did previously. Wait until the following day to water and then do not water again. The grass should be dead within one week, but allow three weeks to transpire prior to replanting the area. If new Bermuda grass appears during that time, repeat the herbicide application a third time.
