Jen from Chicago, Il writes
I have weeds in rocks, have sprayed, but reading how it should be used for weeds in grass.
Tenacity Herbicide is only labeled to be used in turfgrasses for weed control. If there are no desirable plants in the area where you have rock areas, it should not be an issue to just spot treat the weeds there directly, but usually something like RoundUp QuikPro is more used in this case.
