Q.Why my pomegrante tree won’t bear fruit. Very gorgeous flowers, but no fruit.
It has been over ten years and my pomegranate tree produces abundant blooms, but at a certain point they all fall off. Year after year. I have numerous fruit and nut trees which all produce. Is there such a thing as a non-bearing pomegranate tree? I bought one that was a self-pollinator not needing another tree to bear fruit. Was I sold a bill of goods? If I need another tree to promise fruit what should I look for? I bought the tree at Armstrong nursery.
