No, this one isn’t about Poison Ivy, but one that is irritating in a different way.
English Ivy, a non-native invasive species, was introduced to the United States for ornamental purposes. It will quickly and aggressively engulf any structure around it, such as arches and fence-lines. This along with its attractive leaf coloration made it very popular.
However, these qualities also make it easy for English Ivy to quickly engulf and strangle trees, even very large ones. The best approach is to remove the Ivy as soon as it is detected on the trunk of a tree.
If it is already established in a tree, it is best to not rip it out as this can damage the bark. Simply cut the Ivy at its base, it will eventually die off from lack of water and nutrients.
