Waiting to Plant Seed. When you spread an herbicide over your lawn and then decide to patch bare spots, overseed or change your grass type to grow a new species from seed, you should wait at least a month with most pre-emergent weed killers.f you used a crabgrass preventer, that time frame might extend to four months. Check the herbicide manufacturer's label to confirm how long you must wait, as it can differ between herbicide products. The pre-emergent herbicides stop weed seeds from germinating, but they can stop grass seeds as well.
You DO NOT WANT TO USE WEED KILLER ANYWHERE NEAR THE TIME YOU SOW GRASS SEED. The killer doesn't know the difference in grass seed that you want to grow and the weed seeds. There are two types of weeds. 1. Grassy weed (like crab grass) and 2. broadleaf weeds. The best time for killing the crabgrass is EARLY spring.
