English ivy is not native to the U.S. The ivy is prolific; is spread by birds; it wraps the trunk of a tree, reducing airflow to the trunk, and strangles the tree.
If you see ivy growing on your trees, please remove it. If you see ivy on someone else’s trees, please let them know of the danger. I have seen dead trees in Cambridge and Belmont and recently called Harvard to warn them of their dying trees on Garden Street along the Radcliffe Quad.
“What did the tree learn from the earth to be able to talk with the sky?”
Enjoy the holiday weekend!
