There Are Orange Balls On Arborvitae

Question From: PENNSYLVANIA
Q: there are orange round balls on my arborvitae trees - is this a fungus and will it kill the tree

A: My guess is you have a fungal disease known as rust. It will eventually kill the tree if not treated. I would get an on-site inspection from a certified arborist for an accurate ID and treatment.
