About Smooth crabgrass
Digitaria bicornis, commonly known as 'Asian Crabgrass', is a warm-season annual grass that forms clumps, characterized by its prostrate or ascending stems and lanceolate leaves. Its distinctive inflorescences, with digitate spikes resembling fingers, are its most recognizable feature. Although often considered a weed in lawns and crops, it can have ecological value as forage or for erosion control in certain regions.

Care tips
