Soursop Farming Made Easy

Soursop, also called Graviola, is one of those fruits you may have seen at a roadside market but ignored, not knowing its value.

What makes it special? First, it’s packed with medicinal properties and is believed to help with boosting immunity, managing infections, and even used in natural remedies for serious diseases.

Second, it’s rare in Kenya, which means the demand far outweighs supply. Farmers who have ventured into it are enjoying premium prices, especially from health-conscious buyers and juice processors.

With seedlings going for about KSh300, this fruit tree offers a golden chance for farmers and small investors to tap into a niche but rapidly growing market.

Getting Started: The Right Conditions for Soursop

Soursop does best in warm, humid areas. Counties along the coast like Kilifi, Kwale, and Mombasa are naturally perfect, but it also thrives in parts of Western Kenya, Nyanza, and areas around Murang’a and Meru with moderate rainfall.

• Soil needs: Well-drained sandy loam or loamy soils. Avoid waterlogged areas, as the roots are sensitive to excess water.
• pH range: 5.0 to 6.5 (slightly acidic to neutral).
• Temperature: Thrives between 24°C and 30°C. Too much cold or frost damages the young plants.

If your area can grow mangoes and pawpaws well, chances are soursop will also thrive.

Planting Your Soursop Seedlings

Get your seedlings @KSh300 per seedling from Organicfarm Kenya (+254 712 075 915 | oxfarmorganic@gmail.com), you don’t need a huge investment to start.

Here’s a simple step-by-step approach:

• Land preparation – Clear the land and dig holes about 60 cm x 60 cm x 60 cm.
• Spacing – Plant at a spacing of 5m x 5m. This allows each tree to spread well without competition. An acre can accommodate about 150–160 trees.
• Manure application – Mix the topsoil with well-decomposed manure before planting. This boosts root development.
• Planting – Place the seedling in the hole and cover gently without burying the stem too deep.
• Watering – Water immediately after planting, then regularly until the plant establishes itself.
  Plant at the start of the rains — March–May or October–November.

Caring for Your Orchard

Soursop trees are hardy but still need care, especially in the first two years.

• Watering: Regular watering during dry seasons is important, especially when the plant is young. Drip irrigation is the best if available.
• Mulching: Use dry grass or banana leaves around the base to retain moisture.
• Weeding: Keep the area weed-free to avoid competition for nutrients and water.
• Pruning: Light pruning helps shape the tree and encourage more fruiting branches.
• Fertilizer: Apply farmyard manure twice a year. For extra boost, a little NPK 20:20:20 can be used, but avoid overuse.

Expect to spend about KSh 30,000–50,000 per acre annually on maintenance.

Challenges to Watch Out For

Like any crop, soursop farming comes with its share of challenges:

• Pests: Fruit borers and mealybugs may attack. Use organic sprays like neem oil.
• Diseases: Root rot can occur in poorly drained soils. Always plant on raised beds in wet areas.
• Perishability: The fruits spoil quickly after harvest, so having ready buyers is crucial.
  Control tips:
• Use neem sprays (KSh 500/litre) or traps.
• Spray copper-based fungicides (KSh 1,200/pack) if necessary.
• Maintain orchard hygiene.

Farmers can overcome these challenges by organizing into groups, working with cooperatives, and targeting contract buyers. Farmers in Kilifi report cutting losses by over 70% with grafted seedlings and integrated pest management.

Harvesting: When Patience Pays

Soursop takes about 3–4 years to start bearing fruits. Patience is needed, but the returns make up for it.

• A single mature tree can produce 50–100 fruits per year.
• Each fruit weighs between 2–5 kg.
• Harvest when fruits turn light green to yellowish and feel slightly soft to the touch.
• Storage: At 5–7°C with 85–90% humidity, fresh fruits last 1–2 weeks. Processing into juice or extracts extends shelf life significantly.

Market Opportunities for Soursop in Kenya

Right now, soursop has more demand than supply. Some of the key markets include:

• Local consumers – Especially in towns and urban centers where people are health-conscious.
• Juice makers – Soursop juice is gaining popularity in hotels and supermarkets.
• Export market – Countries like the UAE and parts of Europe are buying African soursop at very high prices.
• Pharmaceutical and herbal industries – Known for its medicinal properties, soursop extracts are highly sought after.

The beauty of soursop farming is that you’re not competing with too many farmers, so prices remain attractive. At the market, a kilo goes for KSh200–400, depending on the season.

Do the math, even 50 fruits at an average of 3 kg each gives you 150 kg per tree. At KSh250/kg, that’s KSh37,500 per tree per year. Multiply by 150 trees in an acre, and you’re looking at over KSh5 million annually once mature.
