I am a homeowner and have some problems. I live in NC and have tall fescue grass on lawn. I have some weed that I want to treat and at the same time I want to put down some fertilizer to give the grass a boost since it was looking kinda of brown. Wanted to give it a good green up with the fertilizer. The weeds are also nagging to look at. Which one should I do first - Weed or fertilize? Can I do Both or is it just one or the other? Is there any brand of weed killer or fertilizer you recommend? Thanks.
