I own a tree service in North Carolina and we see that all the time especially with wisteria. I'm sure it's a beautiful thing to see and I have a lot of customers who love the ivy on their trees but as this article stated these ivy plants can be extremely invasive and that 25 ft tree you're talking about, hopefully it's not too close to your house or within a distance that if it fell it would reach your house. When ivy of any kind grows around a tree, it's like a python wrapping around its victim. The IV completely surrounds the outside of the tree and will attach into the bark and grow into the heart of the tree and it starts to suck the nutrients out of it like a leech and after a while it will actually drain the tree of all of its nutrients and then completely suffocated from getting any sunlight. We always recommend removing ivy off of a tree because over time it will kill that tree. Just some advice in case it's a tree that's close to you and you don't want it to die and fall in your house, I highly recommend removing the ivy off of it and moving it to something else that it can climb without being detrimental to it. You can get some lattice and attach it to your house and let it grow on it. My grandfather did that and then as it grew he kept it trimmed and made it look like a heart and ended up doing two hearts intertwined and it looked amazing.
