[align=left]Late October I seeded for a new lawn.* I sprayed my old lawn with a total vegitation killer then I added about 6-12 inches of topsoil*and seeded.* The seed is starting to germinate however I am getting patches of these wild scallions.* The areas are about 6-8 inches in diameter and are rooted in the orginal dirt, they grow up through the new*topsoil.* I have been digging them up but it is getting*to be a little much.* Since the seed is so new I can't imagine I can use any type of weed and feed.* What can I do to prevent them from growing?*[/align]
