Carpet grass is a warm-season, rapid-growth grass type found primarily throughout the southern United States. Because carpet grass grows rapidly, it requires constant mowing and is a less desirable landscaping choice than lower-maintenance varieties such as centipede grass (also found throughout the southern United States). Fortunately, controlling carpet grass is possible in a few weeks with a few inexpensive materials. Eliminating carpet grass from your centipede lawn does not require special landscaping or gardening skills.
Hand-pull patches of carpet grass from your centipede lawn. Throw the grass patches into a plastic trash bag or compost bin.
Cover remaining carpet grass patches with old newspaper and weigh the newspaper down with bricks or heavy weights. Leave the newspaper in place for two weeks.
Remove the newspaper from your lawn and spot-check the area to ensure no new carpet grass has grown in the patches. Hand-pull any new carpet grass growth and dispose of it in a trash bag or compost bin.
Inspect the area on a weekly basis to make sure the carpet grass hasn't returned.
