Hi, I was hoping to get some help with my weeping blue atlas. I live in Southern New Jersey. It was planted by professionals a year ago. It does not get direct sun but gets plenty of water. It has been losing its needles for the past 3 months and they are not brown. A large percentage of them have fallen to the group, I would say over 50% are off of the tree currently. The tree appears to be healthy, I don't see any insects and the bark is good. I am afraid I am going to lose the tree and was looking for some help on what maybe causing the issue. Thank you for any help.
