Can I use this over the top of my ground covers?
Yes, Hi-Yield Grass Killer is labeled for both minor and major vinca ground covers. Mix 1 fluid ounce of this product plus 1 fluid ounce oil concentrate per gallon water; spray to just wet the unwanted weedy grasses. One gallon of spray will treat 1,800 square feet.
