I have poison ivy growing around some mature trees, both oak and pines. Is it safe to spray around those trees?
TZone SE Herbicide is labeled for poison ivy. TZone SE Herbicide is not labeled to harm trees and doesn't make any specific call-outs for caution on the label except for regarding crops/fruit trees. We know, however, some of the ingredients in the product could harm trees or shrubs if it's applied to the tree directly or gets into the root system, so we advise trying to avoid using it within the dripline of trees, especially any that are young or sensitive. If the ground ivy is within the drip line, spot treat with Roundup QuikPRO - 5 x 1.5 oz. packs instead.
