Nimblewill weed is a warm season, highly aggressive weed readily resembling Bermuda grass.  However, unlike Bermuda grass which grows with rhizomes, it produces stolons that run along the surface of the soil.  This extremely invasive weed easily spreads vegetatively by seeds if the plant is allowed to flower, and are then commonly transported by birds, water and lawn equipment.

Typically, nimblewill weed favors moist shady areas but will tolerate sunshine and appears as brown fuzzy patches throughout the lawn.  It is difficult to get rid of because there are no selective herbicides available to effectively manage it.
