What is Crabgrass?

Crabgrass is a common and invasive weed that can quickly take over your lawn if left untreated. It belongs to the Digitaria genus and is classified as an annual weed, meaning it completes its life cycle within one year. As its name suggests, crabgrass gets its name from its distinctive growth pattern, which resembles the shape of a crab. The stems of crabgrass spread out and root freely, allowing it to grow horizontally and form dense mats of vegetation.

There are several types of crabgrass, but the most prevalent species is known as smooth crabgrass (Digitaria ischaemum). This type of crabgrass has light green to yellowish-green leaves with a smooth texture. Another common type is large crabgrass (Digitaria sanguinalis), which has broader leaves and a coarser texture compared to smooth crabgrass.

Crabgrass is a resilient weed that can thrive in various conditions. It prefers areas with full sun exposure and moist soil, but it can also tolerate drought and poor soil quality. Crabgrass seeds can lay dormant in the soil for several years, waiting for the right conditions to germinate and grow. It can quickly invade your lawn, competing with desirable turf grass for nutrients, water, and space.

Understanding the nature of crabgrass and its growth habits is essential in developing effective strategies for control and prevention. In the following sections, we will explore how crabgrass grows, how to identify it, and the best methods for preventing and controlling its spread.

How Does Crabgrass Grow?

Understanding the growth cycle of crabgrass is essential for effective control and prevention. Crabgrass seeds germinate when soil temperatures reach between 55 and 60 degrees Fahrenheit. It thrives throughout the spring and summer months, taking advantage of warm weather and ample sunlight. As the season progresses, crabgrass plants develop tall seed heads, releasing more seeds into the soil for future growth. These seeds are hardy and can remain viable for several years, making crabgrass a persistent and challenging weed to eliminate. Knowing when and how crabgrass grows can help you develop a targeted strategy to combat its invasion.
