Crabgrass is just as icky as it sounds. It’s an annual grassy weed that spreads thousands of seeds during its lifespan. Annual grassy weeds are tough, aggressive plants that thrive on stressed areas of your yard. Dried-out lawns, thin patches, and sun-scorched areas are inviting spots for crabgrass. It only lives for one growing season, so it spreads fast. Over time, crabgrass can overrun your yard if you don’t treat it.
DE-CRAB YOUR LAWN: 3 STEPS TO STOP IT
-
No vacancies
Make crabgrass feel unwelcome by keeping your lawn thick and healthy. If you cut your grass at a high setting on your mower, water deeply and feed regularly, you’ll do a lot to help keep weeds out of your yard.
-
Bring in backup
Apply Roundup® For Lawns in the late spring. For the best results, treat when crabgrass emerges or before the crabgrass is 3 to 4 inches in height. Generally, this period begins or corresponds with the first time that you can see crabgrass in your lawn.
-
Repeat
Use two applications at the same rate with a 14-day interval for dense populations.
