Carpetweed (Mollugo verticillata) is a small weed that can cover large patches of ground in a very small time. This summer annual weed has smooth stems and leaves, and white flowers in the joint between leaf and stem. Carpetweed flowers from July to September.

Maintain a dense, actively growing turf through proper mowing, fertilizing, and watering practices. Mow at the proper height for your selected adapted turfgrass. Coring and traffic control reduce compaction and encourage desirable turfgrass competition. It is best to control this summer annual broadleaf weed in late spring or early summer because it is easier to control at this time and the turf will have a greater chance of recovering the areas previously occupied by weeds.
