Smooth crabgrass is a low-growing annual grass that thrives in full sun to part shade and requires minimal care once established. It tolerates a range of soil conditions and spreads readily, making it more of a lawn weed than a cultivated plant. Most gardeners focus on control rather than cultivation.
