Nimblewill is a dense perennial weed of turfgrass. It is often found at field edges and in forest openings, especially in shaded areas with adequate moisture. Nimblewill grows in a very dense mat, and will root at the nodes. It has very slender, thin leaves, which can be confused with bermudagrass. However, nimblewill has a membranous ligule, which can be distinguished from the hairy ligule of bermudagrass.
Perennial grass weeds are not desirable as turfgrass species under any conditions. Therefore, every effort should be made to prevent these weedy grasses from becoming established in turf, as selective control measures are usually difficult. Selection of adapted turfgrass species and cultivars and the use of cultural practices are important in minimizing weedy grass encroachment and competition. Management practices include (1) mowing at the recommended height for the selected turfgrass and removing clippings when seedheads of grassy weeds are present; (2) applying the proper amount of nitrogen at the correct time according to the turfgrass present; and (3) using soil tests to determine needed nutrients and lime.
