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 Answer: It is generally recommended to wait until your new grass has had 4 mowings. So you are almost there! Be sure that your grass is wet before you put the weed and feed down---so that the weed killer part of it will stick to the weeds.You should probably see wilting on the weeds within 18-24 hours, and they will be dead within a week. Don't put the weed and feed down, if rain is expected within 36 hours.The fertilizer part of it does need to be watered in....so water the whole lawn area very well after the weeds begin to wilt. 2 days after application is probably the best time.est Answer: It is generally recommended to wait until your new grass has had 4 mowings.
