Q.Can this tree be saved?
See picture. Once two identical trees next to the building. Building superintendent went crazy with a saw on his own. Question: is the damaged tree going to die? If not, will it ever grow back to look like the other one?
A second picture shows the needles in detail [I don’t know what kind of tree it is].
Thanks so much. We need to decide what to do with the results of this inappropriate action, remove and plant another tree, try to save it?.
Asked for an email, but have no objection to you using the question.

Yews are very forgiving so I would wait this out till next summer and see how it does. You might show him this article, though, before he trims the other one.
