custard apple tree
I grew a Custard apple tree from seed. It flowers but the tiny, tiny fruit dries up and drops off. Can you please tell me why?

Poor pollination, especially if humidity is low. If the flower is not pollinated, it dies and does not make fruit or the tiny fruit does not develop and thus falls off. You can try hand pollinating to see if this helps. Collect opened flowers and store in a paper bag overnight. They will shed their pollen which can then be brushed onto newly opened flowers using a small artist's brush.
