A: Could be a combination of things. The other trees are shading the one in the middle. It may have contracted a fungus. I would take samples to an independent garden center or nursery along with photos. Your county horticulture agent may also be helpful. A certified arborist is another source of diagnosiip codes. Go to and enter your zip code to find one in your area. Good Luck, Nancy and Happy Yardening.
