Description

Crabgrass is a weedy summer annual that can spread quickly and form colonies. It develops several branching stems at the base with the lower branches tending to sprawl across the ground, while their upper branches are more erect. It prefers full sun to part sun in moist to dry clay loams but is very adaptable to poor soils. It has spread to nearly every state in the country.
