I have a young, 3yrs, Orange tree and although it blooms beautifully the small fruit show up but fall when they reach the size of a pea.

I do spray a bug spray about every two weeks, the ground is sandy and seems to drain well. I fertilize as suggested on the package: March to Oct/Nov.

I have bunches of palms that grow great and have no problems, also some coconut trees that produce well.
