Edible Plants of the World

Soursop

Soursop

A tropical plant. It grows in tropical lowland areas below 1200 m altitude. In Colombia it grows between 100-2,000 m above sea level. It can tolerate quite poor soils and a humid climate. It cannot tolerate frost. The trees can withstand temperatures down to freezing (0°C) for a short time but salt laden winds from the sea can kill the trees. They need a well drained soil and cannot tolerate water-logging. The trees continue to grow and produce satisfactorily in fairly poor compact soil. But improving the fertility increases the amount of fruit. They can grow well in hot humid areas but a fungus disease called Blossom blight can cause flowers to fall off. In XTBG Yunnan. It suits hardiness zones 10-12.

Growing Soursop

Cultivation: Trees are grown either as seedling trees or grafted plants. They can be grown from cuttings or air layering. Trees are easy to grow and maintain. Plants can easily be grown from seeds. Seeds can be planted fresh or stored. Seeds grow in about 15 to 20 days. Trees grown from seeds vary in the quality of the fruit. Seedlings are transferred to polythene bags when 15 cm tall. Trees can also be grown from cuttings or by grafting. This allows better trees to be selected and produced. Seedlings are suitable for grafting after 6 months. Trees need to be about 5m apart. Flowers are pollinated by insects. Hand pollination of flowers can increase the number of fruit that are produced. Fruit are soft and fleshy and difficult to transport.

Edible Uses: Fruit can be eaten fresh or used in ice-cream and for drinks. Young fruit can be cooked as a vegetable. Leaves are edible cooked. They are used for tea. CAUTION The seeds are toxic, so should be removed before processing.

Production: Trees grow quickly. Trees commence bearing by the third year. It bears fruit almost continually throughout the year, but there is normally one season when more fruit are getting ripe. Fruit can weigh up to 4-5 kg each. A tree can produce 12-24 fruit in a year. The fruit contain 11-14% sugars.
