Killing Buttercups

I poured 2 oz Crossbow into each gal of water and sprayed small buttercup plants until wet. I see no change three days later. Why can't I spray again? Thanks


Crossbow Herbicide  can take to two weeks to burn down. Please allow for more time. To increase the kill time, we recommend to mix in a surfactant.
