hairy crabgrass
Quick Summary
Hairy crabgrass (Digitaria sanguinalis) is a species of grass belonging to the genus Digitaria. It is considered a troublesome weed, particularly in lawns and cultivated areas, due to its decumbent stems that root at the joints, forming dense patches.12
Crabgrasses are typically annuals or perennials that spread through seeds and vegetative growth. Eradicating weedy crabgrass species can be challenging. While herbicides can be used before the seeds germinate, a healthy, dense lawn is often the most effective method for smothering crabgrass seedlings.1
