What Is the Best Crabgrass Killer?

The best crabgrass killer depends on your grass type, the growth stage of the crabgrass, the treatment area, and other weeds you may need to control. For crabgrass that is already growing, choose a post-emergent herbicide labeled for crabgrass and your specific turf or treatment area.

 

How Do You Kill Crabgrass That's Already Growing?

To kill crabgrass that is already growing, apply a post-emergent herbicide labeled for crabgrass and your specific grass or treatment area. Crabgrass is generally easier to control when plants are young and actively growing, so identify and treat it early and always follow the herbicide label.

Be sure to read the product labels carefully to select one that’s best for your job and checkout our step-by-step guide for advice on how to get rid of crabgrass in your lawn.
