Dollarweed

Dollarweed is a constant pest weed in warm season lawns. Dollarweed thrives under overly moist, clay soils, but it also invades lawns in loamy compacted soils. Managing soil tilth and moisture are the best defenses against Dollarweed, and a program of regular fertilization combined with high mowing eventually renders it harmless. If your lawn is infested with Dollarweed, mow it high, aerate and topdress, and make sure the lawn is fertilized properly. Once the grass is healthy, treat the lawn using a product containing Atrazine.
