Carpetgrass

Description

Carpetgrass is a slow-growing, medium-green (and sometimes greenish yellow), coarsely textured turfgrass that is adapted to low-maintenance, general-purpose turf. It prefers full sun to moderate shade and performs well in wet, shady, acidic soils where other grasses may not. Carpetgrass looks very similar to centipedegrass except that it produces a crabgrass-like seedhead, and centipedegrass has hairs along the edges of the leaves.

lawn Maintenance for June - August

Disease Control

Watch for Brown (Large) Patch Disease, which shows up as circular patches of brown grass up to several feet in diameter.

Fertilization

Fertilize with ½ pound of nitrogen per 1,000 square feet in mid-June. A second application in mid-August may enhance your lawn if you live along the coast. Use a slow-release fertilizer to help reduce or prevent Brown (Large) Patch Disease. You need to apply pound of nitrogen square feet, but how much fertilizer do you need to buy? Divide 50 by the FIRST number on the fertilizer bag. For example, if you've got a 5-5-15 fertilizer, you divide 50 by 5 and you get 10. That means you need to buy 10 pounds of fertilizer for every 1,000 square feet of lawn.

Insect Control

Check for white grubs, mole crickets, armyworms. On dry, well-drained soils, also check for nematodes. If you suspect nematode damage, ask your Cooperative Extension agent how to submit a sample for analysis.

Irrigation

Make sure your lawn gets 1 inch of water each week. If it doesn't rain enough, you may need to water. In dry, sandy soils, you may need to water ½ inch every third or fourth day. Proper irrigation helps prevent or reduce problems in the summer.

Mowing

Mow grass to 1½ inches with a rotary mower, every 10 to 14 days, or before grass grows above 2¼ inches tall.

Weed Control

Unless your Cooperative Extension agent suggests otherwise, do not make a broadcast application of herbicide. Carpetgrass is sensitive to most herbicides, and most herbicides are not labeled for use on carpetgrass. Manage weeds by hand pulling and mowing.
