Crabgrass

Crabgrass gets it name from the leaves, which form a tight, crab-like circle. This annual weed tends to appear in weak or bare areas of a lawn. Both over and under watering favor its growth, as does consistently mowing the lawn too short. Treat crabgrass in spring with a pre-emergence herbicide to keep seeds from sprouting. Timing is tricky. In regions with forsythia, aim to get the herbicide down as forsythia starts to bloom. Check with your local extension office or a reputable garden center to fine-tune timing in your region.
