Yeah, I said to get all the prep work done 1st. Kill all the existing weeds and make sure you core aerate/dethatch the hell out of lawn. That may take a weekend alone. Mid September will be fine to drop seed.
That's gonna be the case here. I already dealt with a smaller one a week ago on an overhang but that was tiny. This will have a shit ton of hornets in it. Bald-face ****ers too.
Closest to you.
