What's Wrong with my Arborvitae?
We have an arborvitae (I think) that has been growing in the same spot for many years. It was already very large when we bought our house in 2002. Nothing has changed in recent years except that our neighbors cut down a very big spruce tree about 30 feet away last summer. The tree is on the NE corner of our garage, the closest tree to it is a black walnut tree about 15 feet away (to the south). This winter, the arborvitae has started looking very "scraggly" with many "leaves" falling off and now we've noticed that the tree just looks kind of wilted. The bark has developed some streaking that we have never noticed before (more on the north side of the tree). We have another arborvitae on the other side of the garage that looks healthy. I'm worried that it is just getting old. Thank you!! I've read that deer and rabbits can cause this type of damage, but we live in downtown Buffalo so no deer and the damage is too high to be from rabbits. We do have a lot of squirrels.
