Smooth Crabgrass and Hairy Crabgrass
Digitaria Ischaemum and D. Sanguinalis

Annual, grassy

RANGE: Throughout the United States.

APPEARANCE: Smooth and hairy crabgrass have a prostrate growth habit with coarse, light green blades. The blades are short, pointed, and hairy.

GROWTH: This vigorous, warm-season annual grass grows rapidly from early spring until seed heads form in late summer to early fall. It grows especially well in lawns that are watered lightly, underfertilized, poorly drained, and growing thinly. The plant spreads by seed, and to a lesser extent, by rooting from the lower swollen nodes of stems.
