Cultural Practices:
The soursop can be propagated readily from seeds and by budding. It is the most tropical of the annonas.

Blooming Habits:
The large flowers are produced on short stems on the branches and, often, directly on the trunk of the tree. The exterior, cream-colored petals of the flower are thick and fleshy. Hand-pollination greatly improves fruit set, as the stigma of each flower is not receptive until after the pollen has been shed.

Fruiting Habits:
The large dark-green fruits are often irregular in shape but most frequently are ovoid or oblong-conical. The surface of the fruit is covered with numerous, recurved fleshy spines. The flesh is white, slightly subacid, and has a distinctive, pleasant taste. Fruiting is continuous throughout the year, the main crop being produced between June and November. The pulp is sometimes eaten as a dessert fruit after adding a little sugar. It is more commonly used to make a refreshing drink and for flavoring sherbets and ice creams. Jelly and preserves also can be made from the pulp. Care should be taken to remove the unpleasant- tasting skin when the fruit is prepared for consumption. The pulp is a good source of vitamins B and C, and of the mineral phosphorus.
