My Tabebuia avellande is in the same class at the moment. It is growing madly, but puts out only a few blossoms. In Europe fruit growers sometimes partially girdle branches to stimulate fruiting, but I think this is a bit radical. A. Loquats are edible and considered quite good. The Cooperative Extension Office should have a loquat brochure available.
Loquats get fireblight once in a while.
The branch tips will die back. The best thing to do is prune out the dead wood. Loquat is otherwise pretty pest free. Q. I purchased a breadfruit tree in the Keys. A. Breadfruit is a very tender tropical tree that can be grown in Key West and the Lower Keys.
