We just moved into a new construction home, which is surrounded by many evergreen trees (spruces, I believe). It is obvious that some of the trees were damaged during construction. I removed branches that were broken, but now I am noticing that some of the "good" branches are turning brown. Is this normal, or is it related to damage? I'm not sure if I should trim more branches, or just leave it alone and let the tree heal itself.

Thanks.
