Soursop fruit, with its sweet flesh and distinctive flavor, is grown commercially to make juice, candy, sorbet and ice cream.
It's also is purported to have medicinal qualities, with claims across the Internet that soursop extract can slow the spread of cancer or make traditional cancer therapies work better.
Experts warn against using the fruit to treat cancer. While research suggests soursop can fight cancer, it has not been studied in humans. As a result, there is no evidence of its safety or efficacy.

Grafting soursop is not commonly practiced but seems to be making a comeback. We now have several grafted trees but they won't be available for sale for many years. Grafting assures you that you get the same fruit with all the characteristics of the parent. Grafted trees produce much quicker but since soursop seeds grow faster it's often better to just purchase a seed grown tree.

Your tree will grow best when grown in well-drained sandy to sandy loam type soils. The important thing to remember is that the soil drains well and the trees roots get a shower and not ever end up in a bathtub. Soursops do not like wet feet! Soursop trees will tolerate a wide range of soil types including well drained loamy clay soils. Soursop trees grow within a pH range of 5 - 6.5.
