Spinach farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow spinach in Kenya, aim for soil pH 6–7.5 (loam soils); the best-suited counties are Nairobi, Uasin Gishu, Nakuru, Elgeyo Marakwet, Baringo. Apply DAP or NPK at planting and top-dress with CAN at Week 2-3 after transplanting. A well-managed crop yields about 8,000 kg/acre (~KES 200,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing spinach, 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 Spinach
Spinach does best with 600–1,400 mm of rainfall a year at 0–2,500 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 Spinach in Kenya
To achieve maximum yields when farming spinach in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 6 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. Spinach has a high nitrogen requirement, medium phosphorus requirement, and medium 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 2-3 after transplanting), ensures high crop quality and protects your overall farm investment.
How to grow spinach in Kenya
- 1Prepare the soilEnsure soil pH is between 6 and 7.5. Preferred texture: Loam. Apply agricultural lime if your pH is below 6, ideally 30 days before planting.
- 2Plant at the right timeSelect certified spinach seed varieties suited to your altitude zone and plant at the onset of the rains.
- 3Apply basal fertilizerSpinach needs high nitrogen, medium phosphorus, and medium potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 2-3 after transplanting, apply 0.5 bag(s) per acre of CAN. Apply when plants are established. Spinach is a leafy crop and needs nitrogen for continuous harvest.
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 8,000 kg/acre at roughly KES 25/kg.

Frequently asked questions about spinach farming in Kenya
What soil pH is best for growing spinach in Kenya?
Spinach grows best in soil with a pH of 6 to 7.5. If your soil is more acidic than pH 6, apply agricultural lime about 30 days before planting to raise the pH and free up nutrients. The preferred soil texture is loam.
Which counties are best for spinach farming in Kenya?
By soil suitability, the top counties for spinach are Nairobi, Uasin Gishu, Nakuru, Elgeyo Marakwet, Baringo. A full ranking of all 47 counties, each with a suitability score, is shown above.
What fertilizer does spinach need?
Spinach has high nitrogen, medium phosphorus, and medium potassium requirements. Apply a balanced basal fertilizer such as DAP or NPK at planting, then top-dress with 0.5 bag(s) per acre of CAN at Week 2-3 after transplanting.
How much can I earn from spinach per acre in Kenya?
Spinach yields about 8,000 kg per acre. At a market price of roughly KES 25/kg, that is around KES 200,000 per acre in gross revenue, before input and labour costs.
