Crabgrass is a warm-season annual that is easy to establish. Stands of crabgrass can last almost indefinitely if managed to encourage volunteer reseeding. Although often considered a weed, crabgrass is a high-quality forage that can produce 6,000 to 10,000 lb/acre of dry matter annually. The majority of the dry matter is produced from mid-June to August. Crabgrass is adapted statewide and tolerates poorly drained soils well but is not cold hardy. It responds well to split applications of nitrogen at establishment and then again after the first grazing.
