It's Moss Control, not Weed & Feed. I use the Weed & Feed also, but with this summer heat, my lawn wasn't as bright, healthy green as I like. So the guy as Home Depot said to use this. He said it's got lots of iron and the iron kills the moss and makes the grass green. I told him I don't have a moss problem. He said then it will just make your grass green! I said but why would anyone buy this if they don't have a moss problem...he said, "that's the secret!"
