How to Get Rid of Crabgrass
Prevent Crabgrass in the Spring!
Crabgrass can be prevented in the spring so they don't become a problem in the summer. Applying a pre-emergent weed killer, like Scotts® Turf Builder® Halts® Crabgrass Preventer with Lawn Food or Scotts® Halts® Crabgrass & Grassy Weed Preventer in the spring, stops the weed seeds before they germinate.
Crabgrass gets its name because it sprawls from a central root low across the ground. It can become a problem quickly during the summer because it is able to grow vigorously in hot, dry conditions. Before dying in the fall, a single weed can distribute thousands of seeds that will be ready to germinate the following spring. You can take care of crabgrass in your lawn easily with our plan.
Prevention and Maintenance
Mow at The Proper Height
You can discourage crabgrass by mowing at the proper height for your grass type. Higher mowing, usually at one of the top two setting on your mower, encourages lawn grasses to shade soil which helps prevent the germination of crabgrass seeds. A thick, full lawn seldom contains much crabgrass.
Deep Water Your Lawn
Weeds are better adapted to adverse growing conditions than most lawn grasses. Shallow and infrequent watering will only weaken the roots of your grass, while allowing the crabgrass to thrive and take over. Water lawns deeply and less frequently. When you water, wet the soil to a depth of 4-6 inches. This usually requires the equivalent of ½-1 inch of rainfall.
