How to Get Rid of Bahia Grass in a Centipede Grass Lawn

Bahia grass is a warm-season grass that grows throughout Florida, Texas, Louisiana and elsewhere in the southern United States. Because bahia grass is rapidly growing, it is considered high-maintenance and is less desirable than lower-maintenance grass such as centipede grass. Eliminating bahia grass from your lawn or garden is a simple process that should take just a few weeks. Getting rid of bahia grass in a centipede grass lawn does not require specialized landscaping skills.

Hand-pull patches of bahia grass from your centipede lawn.

Dispose of bahia grass into a plastic trash bag or compost bin.

Pull clumps of bahia grass until it is at an even height (no higher than 5 inches). It is important that the bahia grass be even and flat, as this will ensure that the grass will be eliminated when newspaper is spread over the patches.

  • Bahia grass is a warm-season grass that grows throughout Florida, Texas, Louisiana and elsewhere in the southern United States.
  • Getting rid of bahia grass in a centipede grass lawn does not require specialized landscaping skills.

Spread old newspaper over all pulled patches of bahia grass in your centipede lawn. Ensure that the newspaper is lying as flat as possible.

Place bricks or heavy weights on top of the newspaper and leave in place for two weeks.

Remove the newspaper after two weeks and check the bahia grass patches to ensure that no new growth has formed. If necessary, pull any new growth and dispose of in trash bag or compost bin.

Kill Bahia Grass

Bahia grass (Paspalum notatum) is a warm-season grass native to South America. In areas where choicer grasses are common, bahia grass is a tenacious weed sometimes known as "highway grass" because it thrives in sun-baked, unkept roadways. Bahia grass control is a serious challenge, because once it takes hold in an area it’s difficult to kill completely. You may need to take a two-pronged approach, using both manual and chemical methods. The type to choose depends on the variety of turfgrass you are growing. Imazaquin herbicides, on the other hand, are safe on zoysia, centipede and St. Augustine, but will harm tall fescue grass. Fill the bare spots left after you dig out the Bahia grass or after you kill it with herbicide with plugs or sprigs of the same variety of grass that is currently growing. Water the area slowly, to a depth of 10 inches, the day before weeding. Ensure that you remove as much of the root system as possible. Moisten six to eight sheets of newspaper and spread it out over the treated area.

  • Spread old newspaper over all pulled patches of bahia grass in your centipede lawn.
  • Remove the newspaper after two weeks and check the bahia grass patches to ensure that no new growth has formed.

Tip

Spot-check on a weekly basis to ensure that your lawn has been cleared of bahia grass.
