Bermuda grass is a thick growing perennial, commonly used for turf grass, according to the Texas Cooperative Extension. When not used for turf, Bermuda grass is a serious weed, invading gardens and crops. Bermuda grass grows by seed, so when it is mowed it quickly spreads. A combination of cultivation techniques combined with chemical control will help control this difficult lawn weed. If you are against the use of chemicals, a persistent cultivation control will kill the Bermuda grass eventually.
Starve the Bermuda grass of water in areas where this will not affect the health of other landscape plants and grass, recommends the University of California, Davis. Bermuda grass is only slightly drought-tolerant. Rhizomes of the plant will dry out without water for an extended period.
Rake dried rhizomes from the dehydrated Bermuda grass to remove the weed, advises the University of California, Davis.
Mow the Bermuda grass and water it, then place black plastic mulch over the area, recommends the University of California, Davis. Plastic blocks sunlight from reaching the Bermuda grass and kills it. Leave the plastic for six to eight weeks.
Apply a post-emergent herbicide to the Bermuda grass if cultivation controls are not effective. Post-emergent herbicides such as fenoxaprop-p-ethyl products work well with Bermuda grass, according to the Colorado State University Extension. Apply to the Bermuda grass according to the label instructions.
