Its been about a week since I used Sedge Hammer, and I'm happy :) to report that the sections sprayed appear to be "dying off". The nutsedge is turning yellow, but more importantly, its no longer
growing. That alone truly saves on mowing costs.
Since I only got enough to make one gallon, I still have many areas of the "flourishing" weed in my lawn. But at least now I have something to battle it next spring (I don't think I'll try to spray more this year since the season is winding down).
So for those of you w/lawns inflicted with nutsedge, I highly recommend trying Sedge Hammer. :)
