this tree looks like it has two main growing areas instead of one. arent they usually grafted trees? my daughters bought it from a nursery in houston, tx. not sure how to care for it or prune it or what. seems to have some kind of pest problem. leaves are curlying and some insect seems to be making trails in the leaves. i tried to show how trunk is growing . you notice the roots are at ground level. hmmm. . can anybody tell me if this tree is growing right and what i should do to take care of it?
