The cudweeds (Gnaphalium) are comprised of many different species that are similar in growth habits and control measures. In general, the cudweeds have basal rosettes and the leaves and seedheads are covered in distinct fine, white "wooly" fibers. Some cudweeds only have this hair on the undersides of the leaves, and other cudweeds have this hair on all surfaces. Cudweeds overwinter as small basal rosettes, but in the spring usually grow an upright stem.

Proper turf management is important for biennial broadleaf weed control. 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 biennial broadleaf weed in spring or fall, if actively growing at these times.
