Overspray or spray drift of Remedy Ultra Herbicide can harm desired plants. While a light overspray won't be enough to kill a fully matured tree, it can certainly kill the leaves it has contacted. We recommend that you trim back the ivy and then treat the fresh cuts directly with the herbicide so that you are not spraying herbicide over the desirable tree.
