Q.Norfolk Island Pine Tree
Norfolk Island Pine Tree: My tree is loosing individual green “leaves” off branches. We recently moved and my pine tree is not getting direct light anymore, but is in a well lit room. It is also near a heat/ac register but I have a deflector so the air doesn’t blow on the tree. Why would individual green “leaves” fall off?
Thanks,
Trish

Yes, light change and lack of humidity can cause leaf drop.
