Here are the questions I usually ask when someone has a pomegranate that is not producing fruit
1. What variety do you have? Some varieties are ornamental & some fruit bearing.
2. How tall is your tree? My trees have typically grown 5' to 7' the first year except dwarf varieties.
3. How old is your tree? Should let tree start bearing 3-5 years. Pick blooms off first couple of years to encourage tree growth.
4. Does your tree bloom? If so, what type of bloom? Some are ornamental.
5. Have you done a soil test? I knew my soil was poor, so I sent soil samples to Auburn University to be tested. The tests revealed what my soil was lacking and give me the ph level I had.
6. What fertilizer do you use? It is important to feed your pomegranate trees the right food. I had to us lime to raise my ph in order for my trees to properly use the fertilizer I gave them.
7. Have you ever trimmed you tree? In the beginning trim your trees each year to create more branching for high fruit yields. Pomegranates will naturally grow many suckers. You can grow bush form or tree form. Bush form-recommended 4-6 main branches. Tree form-trim off all suckers except one. These are recommended, but I know people who have never done anything and they still produce.
8. Does your tree receive full sun, partial shade, or mostly shade? Pomegranate trees need full sun. The more shade they have the less they grow & fruit.
9. What soil conditions do you have? Such as, is your soil well drained or is it a wet soil type that holds water? Pomegranate trees need well drained soil or they won't grow big enough to produce fruit. If you don't have this you have to build a mound to create it above your soil that holds water.
10. What is your humidity like? Some varieties bloom during rainy season which affects fruit set. Some varieties are poor producers in high humidity.
Since your from Florida, I would contact Pom Natural. They have a high number of Florida heirloom pomegranate trees that are proven to produce in Florida.
