Q.care for junipers with drought damage
How do I care for well established junipers that have recent drought damage? There’s a row of tall (20′?) junipers bordering my property. They belong to my neighbor but he doesn’t take care of them. This past summer we had a particularly brutal hot and dry few weeks, and now some of these trees are turning brown, starting from their tops. I’m fairly certain this really is drought damage, not mites or blight. One is almost half brown. Can they be rescued? How? Do we cut away all the brown stuff down to the trunk? Cut the entire top off?
I appreciate your help! I did try to figure this out on my own but sifted through tons of blight and mite info without finding the answer to my actual question.

Though drought is certainly a possibility for the trees condition, it very well could be a number of diseases that the Juniper would be vulnerable to.
Most of the conditions do not really have treatment due to the fact that the diseases are generally fatal to the trees by the time the symptoms are visible.
A professional Arborist can be called to make a specific diagnosis.
