Crabgrass, hairy crabgrass, summer grass
There are two principal species of crabgrass this article will cover large crabgrass versus smooth crabgrass. Large Crabgrass may be distinguished from Smooth Crabgrass by its larger, hairy leaves. Mature crabgrass may be laying flat along the ground or upright, depending on the growing conditions and in regularly mowed turf they adapt with lower stems. Stems may be as long as 15-30 inches, and are branched at the base and tend to be thin and weak. Leaves are light green and up to about 4-7 inches long. The edges of the leaf blades are covered with fairly long hairs. The flower head is are umbrella-like, consisting of from 3 to 11 slender branches that may be up to 7 inches long. The branches grow from separate and very close points at the end, and a few may grow from the same point. Flowers are arranged on one side of each branch.
Crabgrass is a summer annual grass weed, found in virtually any situation – row crops, roadsides, landscape, and turf. Seeds germinate from very early spring throughout the summer months, and plants mature from late spring through the summer into early fall. Lower joints of the stems also tend to be extended roots where they make contact to the ground, and the plants will spread laterally in this manner.
