Soursop fruit farming

Soursop is a tropical evergreen tree that produces fruit with a prickly yellow-green skin. Also referred to as graviola, all its parts from the root to leaves are edible or has medicinal value. It is a fast growing tree that starts producing fruit in the third year. The soursop fruit is sold in some of the major markets in Nairobi that include; Ngara, city and wakulima. There is no documentation on any commercial soursop plantations in Kenya but a few plants have been spotted in coast, Nyanza and central regions. Soursop (annona muricata) is often mistaken for or referred to as custard apple (annona reticulata) , they belong to the same family- annona, but they are two different fruits. We will explore Custard apple in our next article.

Soursop grows in a wide array of soils as long as the soil is well drained. A soil PH of between 5 and 6.5 is ideal. The soursop tree is small in size and may serve as an intercrop between large fruit trees. Soursop can be propagated from seed or cuttings. Plant well developed seedlings and ensure they are mulched to suppress weeds and to improve moisture retention in the soil. Soursop trees prefer warm and humid conditions to thrive, they are very susceptible to low temperatures. On maturity fruit may emerge anywhere on the tree ; trunk, branches or twigs. The tree will require adequate fertilizing of which we recommend organic compost and mulching using organic material. Young trees can be supported using bamboo sticks.

Flowering Stage

The tree starts to flower and eventually fruit in the third year, fruits are harvested when they are fully developed but still green. Thereafter it takes 2-4 days to ripen. A single tree can produce 60-70 fruits in a year. The fruit should be handled with care when harvesting to avoid bruising it. After harvest prune slightly as you eliminate dead wood. Soursop may be directly consumed when ripe or processed into ice cream, syrup, smoothies, juice, pulp etc. The fruit has a white fleshy and fibrous pulp with a sweet sour flavor and is rich in vitamin B and C.

There are various pest and diseases that attack the soursop tree. Locally it is more vulnerable to the fruit fly and aphids. Plant disease free seedlings and monitor your plants for any pests and diseases. In case of any attacks consult your extension officer; we do also assist farmers by offering them professional advice concerning the same. We have stocked a few soursop plants that are ready for planting, feel free to visit our demonstration project at kariobangi north primary or our main nursery at Thome, Kasarani. Happy gardening and make sure you plant a fruit tree.
