Crabgrass (Digitaria Sangualis)
Crabgrass is an annual weed that grows from seeds produced last year. The most effective way to treat crabgrass is to prevent the seeds from germinating. That's why our first lawn care application is a granular fertilizer with a pre-emergent for crabgrass control. This helps the lawn grow and prevents the grassy weeds like crabgrass, quack grass, and barnyard grass.
Interesting Facts About Crabgrass:
- Crabgrass seeds are dormant for a short period of time after they shed from plants.
- When the soil temperature at the surface reaches 55°F for four or five consecutive days, crabgrass begins to germinate.
- Purplish seed heads form until frost kills the plants.
- Plants that emerge early in the season and have a long period of vegetative growth are much larger and more competitive than plants that germinate late in the season.
Generally April and May is the ideal time to apply pre-emergent fertilizers to prevent crabgrass. The active ingredient for pre-emergent crabgrass control in fertilizer is prodiamine, and works best before the crabgrass has emerged. Crabgrass can also be treated with a post-emergent weed control product. The most effective way to get rid of crabgrass is to promote thick turfgrass to cover the ground. Make sure to wait at least a few days after the application for it to be able to dry and take effect.
