The Q&A Archives: poison ivy

Question: The full grown evergreen in our front yard has poison ivy growing under it and up the center and through the branches. Because of its size, treatments seem impossible. Any suggestions?

Answer: I would start at ground level, cutting off all the stems and vines of the poison ivy and then pulling them out of the tree. Once they are cut off at ground level the vines will not continue to grow but will die in the tree. You will probably be pulling them out for years to come. After cutting the stems and vines, paint the stubs of the poison ivy with full strength Round Up or Brush B Gone. Take care not to spill it on the soil or get it on the tree trunk or any above ground roots. The Round Up will move down into the roots of the poison ivy and kill them off. You may have to make repeat applications. Used with caution and only on the poison ivy, Round Up will not affect your evergreen. It does not move into the soil, it remains in the poison ivy stems and roots until it degrades naturally. Good luck with your project.
