I don't know what I'm going to do. I read this thread earlier today, and I believe I may have a rust issue. http://www.lawnsite.com/showthread.php?t=387172
I'm considering top dressing, but I'm not sure there would be any point if I don't aerate along with the topdress. If I do topdress, maybe I would be better off using their blended compost, or their garden amendment.
I guess if I'm going to do anything at all, I need to get on it.
