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.
Best results are achieved when applied on a sunny day when the temperature is between 45 degrees and 85 degrees F. Long weeds should be trimmed down before application. Weeds will yellow and wilt within 10 hours. They will be dead in one to two weeks and should not grow back for one year.ost weeds will show signs of wilting or yellowing of new growth within 24 hours of application. Necrosis will spread, turning weeds brown and killing them within 14 to 28 days. If seeds were fully developed before the weeds die, they will still be viable, however.
