Crabgrass is a pesky weed that eludes lawn care professionals all over the country. Once native to Europe and Eurasia, crabgrass was introduced to the United States in 1946 as a forage crop. Now, crabgrass is found almost everywhere on all kinds of turf but thrives in lawns.

Crabgrass appears in early summer. Because of its hardiness and ability to evade lawn mowers, crabgrass is especially difficult to manage. In addition to being tough, crabgrass has a short dormancy period, and a single plant can produce up to 150,000 seeds. When soil temperatures hit 55 degrees Fahrenheit for at least a week, crabgrass enters the germination stage. 

Managing Crabgrass 

Crabgrass is best managed during the germination stage. Once soil temperatures reach 55 degrees Fahrenheit, an application of a pre-emergent herbicide can keep crabgrass under control. Even with a pre-emergent application, crabgrass can still appear in the summer. An application of post-emergent herbicide will kill crabgrass growth.
