Question
How do I get rid of a poison ivy vine up my tree? This vine won't pull off and is about as thick as your arm. It has climbed pretty high on the tree.

Answer
You can kill the vine with a herbicide called Roundup.
IF you can reach the leaves spray them with Roundup and the plant will transport the herbicide to the roots killing the vine. OR if you can not reach the vines leaves, cut the vine and apply Roundup to the lower cut and this will kill the vine. IF you cut the vine I would wear gloves since the juices in the vine will cause one to break out as if they touched the leaves.

Poison ivy is difficult but not impossible to eradicate. The chief difficulty lies in the chances of becoming poisoned when trying to remove it. Wear protective clothing, including gloves, whenever you are working near it. Pulling and grubbing are effective means of removal, though they necessitate close contact and will probably need to be repeated once or twice for complete control. If time is not an object, the vines can be smothered by completely covering them with black plastic for several months. Do not mow the plants as this will spew bits and pieces of poisonous material over the area. When removing poison ivy, take frequent breaks to change clothes and scrub thoroughly with a strong soap. Wash contaminated clothing separately. DO NOT BURN any plants that you physically remove. The resulting smoke can cause severe lung damage if inhaled.

Herbicides are effective and allow you to control the plant without getting too close to it. Several commercial products are available. Check labels to find one that will control poison ivy, and apply it as directed. Many of the herbicides for poison ivy control contain glyphosate. This chemical is systemic. It is absorbed by leaves and transferred to stems and roots, and slowly causes the death of the entire plant. It must be applied to an actively growing plant for this process to take place; do not apply it during a drought when even poison ivy will not be growing. Glyphosate, like most herbicides labelled for poison ivy removal, is nonselective and will kill any other plants it contacts.
