How To Get Fruit From Sour Sop Tree

Question

Do I need two trees to get pollination and fruit

Answer 1

No, you don't need two, however, even though soursop tree flowers have both male and female organs, the male part matures sooner and sheds its pollen before the female part is receptive, making pollination by beetles difficult. You may need to hand pollinate the flowers.
