Question Asked: Hello, I wanted to submit a few photos of this tree like ivy that is taking over a tree next to my home. The branches are extended from one massive vine that starts at the base of the tree and runs about 25 feet up the tree. It has the "leaves of three" and some small berries very similar to what I have seen on your site. The only thing that seems unusual is that the branches are six to eight feet long and very woody like an actual tree branch. I hope it is something else, but if it is poison ivy, the whole tree is coming down! I included a picture of the vine and as you can see it has the small fibrous hairs all over it and the vine itself is close to 3 inches in diameter. I live in Southwest Missouri and this area is plagued by poison ivy!! Thanks for your help, Jason

Answer: Jason - well if you read the synopsis you know the verdict. yeah - that's poison ivy. I've seen limbs from the main vine easily 10' to 12' long. One of the characteristics of poison ivy is the woody vine / branches. The "hairy" you see on the tree are the aerial rootlets. I've seen vines so "hairy" that you couldn't see the vine and then others where the "hair" was difficult to see but definitely there. You could kill the vine BUT prying all of that off the tree is not much fun. If the tree doesn't mean much to you, I'd just take it down. Be sure to dig up the poison ivy root otherwise you may see it coming up again next year.
