My tree is approximately 8 -10 years old and is about 25 -30 feet high, it gets full sun until around 6pm in the summer. We water the yard periodically and I feel it is probably getting enough water. The past two years the tree sprouts new green leaves and flowers. Soon after most of the leaves turn reddish as if it is going into fall. I really didn't think it would come back after last year. The leaves are still on the tree, but are red. Any suggestions? Thank you.
