Pumpkin farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow pumpkin in Kenya, aim for soil pH 5.8–7.5 (sandy loam soils); the best-suited counties are Nairobi, Kajiado, Uasin Gishu, Nakuru, Elgeyo Marakwet. Apply DAP or NPK at planting and top-dress with CAN at Week 4 and at vine-run. A well-managed crop yields about 10,000 kg/acre (~KES 300,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing pumpkin, certified seed varieties, seasonal fertilizer guidelines, and a detailed per-acre production budget to set you up for a successful harvest.
Soil requirements
Growing conditions for Pumpkin
Pumpkin does best with 500–1,200 mm of rainfall a year at 0–2,100 m above sea level. In drier areas, irrigation or water harvesting closes the gap; outside the altitude band, growth and yields drop.
Optimizing soil and fertilizers for Pumpkin in Kenya
To achieve maximum yields when farming pumpkin in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5.8 to 7.5. Soils that fall outside this range can lock out essential macro and micro-nutrients, leading to stunted growth or crop failure. For acidic soils, applying dolomitic or calcitic agricultural lime is recommended at least 30 days before planting to normalize acidity.
Fertilizer application should be calibrated based on the crop’s nutrient demands. Pumpkin has a medium nitrogen requirement, medium phosphorus requirement, and high potassium demand. Using certified seed varieties suited for your specific altitude and rainfall pattern, combined with a precise basal and top-dressing program (such as applying CAN at Week 4 and at vine-run), ensures high crop quality and protects your overall farm investment.
How to grow pumpkin in Kenya
- 1Prepare the soilEnsure soil pH is between 5.8 and 7.5. Preferred texture: Sandy Loam. Apply agricultural lime if your pH is below 5.8, ideally 30 days before planting.
- 2Plant at the right timePlant pumpkin during Long Rains (Direct Sowing & Basal–Fruit Development & Harvest) or Short Rains (Direct Sowing & Basal–Fruit Development & Harvest), timed to the start of the rains.
- 3Apply basal fertilizerPumpkin needs medium nitrogen, medium phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 4 and at vine-run, apply 0.4 bag(s) per acre of CAN. Top-dress when vines begin to run. Add potassium at fruit set.
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 10,000 kg/acre at roughly KES 30/kg.

What fertilizer does pumpkin need?
Pumpkin has medium nitrogen, medium phosphorus, and high potassium requirements. Apply a balanced basal fertilizer such as DAP or NPK at planting, then top-dress with 0.4 bag(s) per acre of CAN at Week 4 and at vine-run.
When should I plant pumpkin in Kenya?
Plant pumpkin during Long Rains (Direct Sowing & Basal to Fruit Development & Harvest) or Short Rains (Direct Sowing & Basal to Fruit Development & Harvest), timed to the start of the rains in your area.
