I have 2 trees that I do nothing too except trim lower limbs. I never fertilize or water. They produce 100's of the best satsumas I have ever eaten. The trees are 20 years old. It took 3 years for them to produce the first fruit. Have you trimmed the tree? It won't produce fruit on first year growth only 2 year old and older branches. Did you have bees when it bloomed?
