Cauliflower farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow cauliflower in Kenya, aim for soil pH 6–7.5 (loam soils); the best-suited counties are Uasin Gishu, Nairobi, Nakuru, Elgeyo Marakwet, Narok. Apply DAP or NPK at planting and top-dress with CAN at Week 3 and 6 after transplanting. A well-managed crop yields about 10,000 kg/acre (~KES 600,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing cauliflower, 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 Cauliflower
Cauliflower does best with 700–1,500 mm of rainfall a year at 1,200–2,800 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 Cauliflower in Kenya
To achieve maximum yields when farming cauliflower 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. Cauliflower has a high nitrogen requirement, high 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 3 and 6 after transplanting), ensures high crop quality and protects your overall farm investment.
How to grow cauliflower 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 timePlant cauliflower during Long Rains (Nursery & Transplanting & Basal DAP–Head Formation & Harvest) or Short Rains (Nursery & Transplanting & Basal–Curd Development & Harvest), timed to the start of the rains.
- 3Apply basal fertilizerCauliflower needs high nitrogen, high phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 3 and 6 after transplanting, apply 0.5 bag(s) per acre of CAN. Apply boron foliar at 4 weeks to prevent hollow stem. Avoid excess nitrogen after curd set.
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 10,000 kg/acre at roughly KES 60/kg.

Frequently asked questions about cauliflower farming in Kenya
What soil pH is best for growing cauliflower in Kenya?
Cauliflower 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 cauliflower farming in Kenya?
By soil suitability, the top counties for cauliflower are Uasin Gishu, Nairobi, Nakuru, Elgeyo Marakwet, Narok. A full ranking of all 47 counties, each with a suitability score, is shown above.
What fertilizer does cauliflower need?
Cauliflower has high nitrogen, high phosphorus, and high 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 3 and 6 after transplanting.
When should I plant cauliflower in Kenya?
Plant cauliflower during Long Rains (Nursery & Transplanting & Basal DAP to Head Formation & Harvest) or Short Rains (Nursery & Transplanting & Basal to Curd Development & Harvest), timed to the start of the rains in your area.
How much can I earn from cauliflower per acre in Kenya?
Cauliflower yields about 10,000 kg per acre. At a market price of roughly KES 60/kg, that is around KES 600,000 per acre in gross revenue, before input and labour costs.
