How to kill crabgrass on your garden lawn – two steps to keep the weeds from coming back


Crabgrass appears as a coarse, light green clump of grass that typically grows on lawns. The weed gets its name from its low-lying, sprawling, crab-like elements. Although it can be pulled out, this annual weed can become a headache for gardeners who return year after year.

There are a few types of crabgrass to watch out for, including hairy and smooth crabgrass.

Hairy crabgrass is also sometimes called long crabgrass and tends to grow a bit longer than smooth crabgrass.

Hairy weed (Digitaria sanguinalis) is named for the tiny hairs or fibers that grow on its leaves and stems. This form of crabgrass is coarser and has wider blades.

Smooth crabgrass (Digitaria ischaemum) has no hairs around the sheath or leaves. Sometimes called crabgrass, this weed can grow up to six inches, but is often shorter than its hairy counterpart.
