Bahia grass was developed for use in drought-prone sandy pastures of the Southeastern U.S. It was introduced in the U.S. in the 1930s as a grass for cattle. It spreads by seed and underground rhizomes. The lightweight seeds are produced over the entire growing season, so even if the grass is not growing it can show up in ornamental flower beds in Pensacola, Fla. A combination of methods are needed to keep Bahia grass under control in ornamental flower beds in Pensacola.
Add moisture to the area where the Bahia grass is to make it easier to remove from the soil.
Dig straight down, using a shovel, 6 to 8 inches deep around the roots of the Bahia grass about 4 inches from the plant. Move the shovel back and forth to loosen the root system of the Bahia grass clump. Be careful not to damage the root systems of any desirable plant nearby.
Pull the Bahia grass clump from the ground while wearing a pair of garden gloves. Shake off the loose soil from the root system. Dispose of the Bahia grass clump.
Cover the area where the Bahia grass was growing with a 2-inch layer of mulch to prevent it from regenerating from leftover roots. Treat any remaining Bahia grass by pulling it up by hand or spraying with a weed-killer containing glyphosate, which will kill anything it touches.
