I'd like some help figuring out what the cause of my unhealthy tree is in addition to suggestions on how to fix it.
The tree is at least 3 years old; I've lived in the house 2 years and each year it looks the same. Its leaves are droopy, bark peeling, and the leaves never reach the top of the branches.
I've watered regularly, treated it with root stimulant, pruned dead branches, pruned leaves sprouting from the base of the trunk and nothing seems to work.
I appreciate any help!
EDIT
Also, the tree gets full sun everyday in Dallas, Texas.
