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.
