I have some poison ivy to kill, and some of it is climbing my trees. Can I spray Roundup on this stuff or will it hurt the trees? Trees are a variety - oak, cedar, sycamore, elm. A few Virginia pines, too.
TreeCo said:Roundup can do a lot of damage to young trees. On young trees the outer bark is still alive and roundup can kill it. On older trees the outer bark is not alive and roundup does no damage.
