Answer: Cherimoya, or sugar apple, should be easy to grow in Florida. Sugar apple trees produce flowers on -1 to 2-year-old wood and newly emerging shoots. Natural fruit set ranges from near zero to about 3% and fruit production may be severely limited by poor fruit set and fruit shape. This is due in part to the absence of their natural Nitidulid beetle pollinators in some areas and/or a lack of sufficient pollination during flowering. Misshapen fruit is caused by incomplete pollination.

Sugar apple have complete flowers, however, the male and female flower parts are functional at different times of the day. Sugar apple flowers first open during the day and the female parts are receptive to pollen (female stage); early the next morning the flowers open wider and shed pollen (male stage). Subsequently, in the late afternoon and early evening, the male flowering stage occurs and the anthers release pollen.

There's not much you can do to encourage better fruit set except to keep your trees healthy and flowering. Eventually you'll get some fruit. When you do, I know you'll enjoy!
