My cousins yard was a disaster, lots of weeds everywhere so I sprayed it last fall with roundup and killed everything so we could start over with tall fescue. I areated and overseed along with starter fertilizer around the first of october. Well he didn't do too good of a job watering it and there some bare spots still in it that he wants me to fix. The rest of the yard is looking good. What should I do... should I aerate it agin and put more seed in the bare spots and then wait how long to start mowing??? Waiting to fall to overseed is the last choice.
