• Buffalo grass is a warm season perennial that grows to a mature height of 8 to 10 inches. The grass spreads from stolons, runners and seeds. Buffalo grass has a light blue-green color and creates a thick, fine-textured turf. It displays a high tolerance to heat and extended drought. The grass does not fare well in areas of heavy traffic or overgrazing. It is simple to remove buffalo grass when it appears in lawns and flowerbeds, since it is readily overtaken by other forms of cultivation. There are a number of ways to kill unwanted buffalo grass appearing in the garden.
  
  

Glyphosate

• Glyphosate is effective for killing any green and newly emerging buffalo grass in lawns when the chemical is applied heavily and allowed to soak into the roots of the grass. Glyphosate is a non-selective, systemic herbicide sold under various trade names. Products containing glyphosate as the active ingredient can be used on a wide range of perennial and annual plants, including sedges, woody plants and grasses. Glyphosate is easily absorbed by most soils, especially soils that are rich in organic matter.
  
  

Vinegar

• Vinegar is an effective organic solution to getting rid of unwanted buffalo grass. Using white or pickling vinegar is a safe alternative to using environmentally unsafe chemicals for the removal of unwanted plants. It is best to use the vinegar on buffalo grass on extremely hot days. To use vinegar, saturate the area of unwanted grass and continue for a few days until the grass is killed. Use full-strength vinegar without dilution. Do not use vinegar near desired plants, as the vinegar will harm any plant with which it comes into contact.
  
  

Plastic Sheets

• Unwanted buffalo grass can be killed by smothering with black plastic sheets that are available at garden and home stores. Black plastic is more effective than white as it blocks out light better than white plastic. Before applying plastic, cut the grass short and then cover the area of unwanted grass with the plastic. Using large rocks, secure the edges of the plastic sheet and allow to remain in place for three or more weeks. After grass is killed, you can either remove the plastic or leave it in place, securing it with mulch and cutting out holes for any new plants.
