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.
Grass seed can be sown 14 days after the last application of Weed-B-Gon. Before planting grass seed, add a starter fertilizer to give the grass seed the nutrients needed to grow after they germinate. If you don't want to use a fertilizer, amend the soil with compost to give the soil the rich nutrients needed.o not walk on the grass while it is wet with the weed killer. Keep pets and children off the grass until the spray has dried. Once the grass dries after an application of Weed-B-Gon, anyone including pets can walk on the grass. The grass can be mowed 24 hours after applying the weed killer.
