How soon can I sow seed after applying a weed control product?
In this case, it is essential to check information on the bag. Because weed killers vary in their ability to linger and prevent seed from coming up, the answer will depend on the product. Always follow the label directions. Crabgrass Preventer: Do not sow seed within 4 months of applying crabgrass preventer. By fall, which is the best time to sow seed of cool-season grasses anyway, you should get good results from seeding. You can plant sod in areas treated with Crabgrass Preventer after 1 month. Weed and Feed: You will get better germination if you do not use Weed and Feed for at least four weeks prior to planting seed.
