Crabgrass gets its name because it sprawls from a central root low across the ground. It can become a problem quickly because it is able to grow vigorously in hot, dry conditions. Before dying in the fall, a single weed can distribute thousands of seeds which will be ready to germinate in spring. Crabgrass is a problem, but you can take care of these weeds in your lawn easily with our plan.
Apply a lawn food that contains a pre-emergent, such as Scotts® Turf Builder® with Halts® Crabgrass Preventer in early spring (before temperatures reach 65°F). It will feed your grass while providing a barrier that prevents crabgrass seeds from germinating.
If in spite of all your efforts crabgrass shows up in your lawn, fight back. Apply Ortho® Weed-B-Gon MAX® Plus Crabgrass Control. Mature crabgrass may require a second treatment 2 weeks later. Also, be careful with newly seeded lawns. Don't apply until you've cut your new grass at least 3 times.
