Cucumber farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow cucumber in Kenya, aim for soil pH 5.8–7 (loam soils); the best-suited counties are Nakuru, Narok, Baringo, Elgeyo Marakwet, West Pokot. Apply DAP or NPK at planting and top-dress with CAN at Week 3 and 5 then at flowering. A well-managed crop yields about 12,000 kg/acre (~KES 480,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing cucumber, 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 Cucumber
Cucumber does best with 500–1,200 mm of rainfall a year at 0–2,000 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 Cucumber in Kenya
To achieve maximum yields when farming cucumber in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5.8 to 7. 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. Cucumber has a high 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 3 and 5 then at flowering), ensures high crop quality and protects your overall farm investment.
How to grow cucumber in Kenya
- 1Prepare the soilEnsure soil pH is between 5.8 and 7. Preferred texture: Loam. Apply agricultural lime if your pH is below 5.8, ideally 30 days before planting.
- 2Plant at the right timePlant cucumber during Long Rains (Direct Sowing & Basal–Fruit Development & Harvest) or Short Rains (Direct Sowing & Basal–Harvest), timed to the start of the rains.
- 3Apply basal fertilizerCucumber needs high nitrogen, medium phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 3 and 5 then at flowering, apply 0.4 bag(s) per acre of CAN. Add foliar potassium at fruiting for fruit size and quality.
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 12,000 kg/acre at roughly KES 40/kg.

Frequently asked questions about cucumber farming in Kenya
What soil pH is best for growing cucumber in Kenya?
Cucumber grows best in soil with a pH of 5.8 to 7. If your soil is more acidic than pH 5.8, 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 cucumber farming in Kenya?
By soil suitability, the top counties for cucumber are Nakuru, Narok, Baringo, Elgeyo Marakwet, West Pokot. A full ranking of all 47 counties, each with a suitability score, is shown above.
What fertilizer does cucumber need?
Cucumber has high 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 3 and 5 then at flowering.
When should I plant cucumber in Kenya?
Plant cucumber during Long Rains (Direct Sowing & Basal to Fruit Development & Harvest) or Short Rains (Direct Sowing & Basal to Harvest), timed to the start of the rains in your area.
How much can I earn from cucumber per acre in Kenya?
Cucumber yields about 12,000 kg per acre. At a market price of roughly KES 40/kg, that is around KES 480,000 per acre in gross revenue, before input and labour costs.
