I took a look at the other answer. It seems that the links take you to places that show the requirements of the tree. If they are met, then flower drop will not occur. I took the liberty of extracting all of the very useful information.
It boils down to pH, soil nutrients, moisture level, temperature, and nutrient content of soils.
You will need to test your soils.
