Blue Spruce dropping needles
My blue spruce is dropping needles in an isolated spot about half way up the tree - about 5' off the ground. The needles turn brown and then drop off the branch. Any clue as to what could be causing this and how to stop it? I've read about the fungal diseases that could cause needle shedding, but they seem to start at the base of the tree and work their way up - not what I have.
