Crabgrass in the Lawn
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.
What To Do if Crabgrass Has Taken Root
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.
