I'd stay away from the patchmaster. I don't remember exactly what's in it, but I think it has a fair amount of annual rye, which germinates in a hurry, but won't last. If I were you, I'd use a good quality seed and cover it with some kind of mulch to get the same effects as you get from the patchmaster.

How large are the bare spots? KBG will fill in bare spots as log as they aren't too big. Technically, they'll fill in the big ones, also, but it will take longer.

Well, what I am planning to do in about 3 weeks which I think should be enough time to get the Dimension down is soil, is to dig out dirt in that area (area is about 3 inches wide but 8 inches long on a slope)then put some KBJ (this area of yard is sunny)then put Patchmaster on top of it for staying power. Has anyone ever done this after using pre-emergent?
