How to Grow and Care for Crabgrasses

Hairy crabgrass (Digitaria sanguinalis) is a plant species that is known worldwide as a common weed. In certain circumstances, hairy crabgrass is used as animal fodder. This grass species is extremely hardy and almost always requires a detailed control plan, as any chemicals used to eliminate it may also harm surrounding grasses.

Southern crabgrass (Digitaria ciliaris) is an aggressive grass that likely originated in Asia but is now found throughout the world. It is hardy and adaptable to different soil types, and is often considered an invasive weed, especially in North America and China. If not in an area that threatens crops, however, southern crabgrass can be utilized to stabilize and protect the soil.

Smooth crabgrass is a weed commonly found in yards and other turf. This low-growing grass typically reproduces from seed. Although commonly found in lawns, this species of crabgrass is not as aggressive as other types.

Violet crabgrass (Digitaria violascens) is a very widespread grass that has spread across much of the world. It is therefore considered an invasive species in parts of the USA. The scientific name violascens and the common name Violet crabgrass both draw attention to the upper lemma of the plant's flower heads, which are purple.

Trailing crabgrass is a grass species typically embracing warm climates where its slender stems and flat, linear leaves thrive. It forms a mat-like structure, spreading efficiently through its fibrous root system. The plant's small seeds cluster on spikelets, making it robust in propagation. Its growth habit allows trailing crabgrass to withstand moderate trampling, a testament to its resilience.
