I want to fertilize the lawn. Its been 4 weeks since the Billy Goat set the seed down. I have heard that you should use weed control seperate from your fertilizer. I don't want to spray. The real question is if a weed and feed to be used. what one? If I do use a weed control what one? If I do use a separate fertilizer what one? All products will come from my local lesco dealer here in CT. Thanks......(as always)!
