I don't know where you are, but in Arkansas when we lived there, the garden
man would come on TV and answer peoples questions. He always advised adding
a "super phosphate" for trees and flowers that didn't bloom or set on fruit.

Here, in western Kansas, the soil has plenty of phosphate. You might do a
soil test and if the phosphate is low or marginal try that. He always
recommended a 0 - 46 - 0 rated fertilizer to get the "super phosphate".
Follow the directions on the bag.
