How to Rid Yard of Centipede Grass
- 1). Dig out any patches of centipede grass found in garden beds. Pull out the grass by hand, and use a hand spade to remove any stubborn roots left in the soil. Deposit the grass clumps in a trash bag.
- 2). Dig up clumps of centipede grass in a lawn with a shovel. Loosen any accumulated thatch by driving the tip of the shovel into the grass repeatedly. Work the tip of the shovel into the ground, then pry up a clump of grass. Make sure to remove all the centipede grass, its roots, and from 2 to 4 inches of soil from any area covered with centipede grass. Deposit the grass clumps in a trash bag.
- 3). Kill large patches of centipede grass using a glyphosate-based herbicide. Mix a batch together following all warnings and directions on the product labeling. Apply the herbicide using a wick or pad applicator, or by careful spraying. Avoid getting herbicide on any desired grass or plants, as glyphosate is non-selective and kills indiscriminately. Wait for the grass to wither and die. Dig it up and dispose of it in a trash bag.
- 4). Reseed lawn areas with your desired grass type as soon as possible after digging up the centipede grass to prevent more undesired grass or weeds from taking over the spot. Read the label on herbicide containers to determine how you have to wait to reseed after application.
