One suggestion I got was to round up the entire area and reseed after it wears off. I really wasn't all that enamored of the idea of putting that kind of poison on a large area of the yard.
Haven't seen any seed heads, and am going to keep it mowed low for the rest of the season.
What about aerating to assist new growth in the fall? Will that give the overseeding a boost?
