Do I spray the base of the poison Ivy or the entire vine as far as I can reach on the tree?
Yes, Roundup Pro Concentrate is a non-selective herbicide, so it will help to control the poison oak. You can cut the vine and apply the product to the fresh cut for best results. Please be sure to review the product label for more information and complete application instructions before use.
