Hairy vetch is a winter annual, biennial, or summer annual weed that forms large mats of vegetation. 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.
