Just checking in to see who uses this stuff later in the summer or for "cleanup" before overseeding. I'm going to give it a shot for my late June and early August application. Just wanted to see some opinions and what your results were after using it. Like visible response time from the crabgrass, response time for sedges and broadleaves and did you ever have to reapply or did it do its job after the first app? I'm moving away from the Q4 plus and am giving this a shot.
