Well, it has only been about 36 hours but the yellow patch I had in the backyard (about 3' squared) is starting to green up a bit after putting some more fertilizer on it. I need to cut it tonight but I am going to cut it about 3/4" higher than I normally do, and see what that does after a month or so. I hate waiting for the little seeded areas to start coming up, but I am watering them daily so we'll see how that goes also.
