Crabgrass is a common weed in many lawns. Crabgrass is an annual, warm-season grass that begins to germinate when soil temperatures reach 60 F. Germination usually begins about mid-April in southern Iowa, early May in northern parts of the state. Crabgrass continues to germinate over several weeks from spring into summer.
