The Q&A Archives: poison oak/ivy

Question: any chemicals on the market to kill poison ivy/oat by trees with out killing the trees?

Answer: You can work at this by cutting the stem of the poison ivy at the base near the ground. Then paint the cut end of the stem with an herbicide containing glyphosate. If it resprouts from the root, repeat the treatment. The cut portion will die off and eventually break apart and fall out of the tree. Handle the dead parts with care as they will still contain the irritant and can cause allergic reactions.
