Crabgrass dies on its own each year in fall. If you can wait it out, the weed will be gone by winter, and crabgrass won't return if you apply a pre-emergent next spring.

What do you do with crabgrass in the fall?

Crabgrass plants will be killed by frost in the fall, leaving behind bare spots. Don't panic! All you need to do is repair the bare spots to help keep new weeds out. Fill the spots with a patching product, like Scotts® EZ Seed® Patch & Repair, and keep it watered until the new grass is established.

Should I pull crabgrass in the fall?

Crabgrass will die on its own in the fall, usually after first frost. However, if you don't remove it before it disperses its seeds, you will have to deal with the pesky weed again the following year. The best way to get rid of crabgrass is to remove the weedy clumps as you see them.
