Orange blossoms fall before oranges can grow
I have had an in-ground dwarf orange tree in my backyard for 3, if not 4 years now. When it was purchased and planted it already had several wonderful oranges on it. The years following, have not produced a single orange. I have observed that while the tree seems to be thriving and the blooms are in abundance, the blooms along with the tiny green balls that would be future oranges at their bases, fall completely to the ground before oranges get a chance to grow. What is going on and how can I prevent it from happening? I still have some blooms on the tree as of right now, but hundreds have already fallen to the ground. Would like to save a few this year, if possible.
