Garlic farming guide — Kenya
Soil requirements, top counties, seed varieties, fertilizer plan & economics
To grow garlic in Kenya, aim for soil pH 6–7.5 (sandy loam soils); the best-suited counties are Nairobi, Nakuru, Kajiado, Baringo, Narok. Apply DAP or NPK at planting and top-dress with CAN at Week 3-4 after planting. A well-managed crop yields about 3,000 kg/acre (~KES 825,000 gross per acre).

This comprehensive guide maps out the optimal soil requirements (such as target pH ranges), the most suitable counties for growing garlic, 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 Garlic
Garlic does best with 500–900 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 Garlic in Kenya
To achieve maximum yields when farming garlic 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. Garlic 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 3-4 after planting), ensures high crop quality and protects your overall farm investment.
How to grow garlic in Kenya
- 1Prepare the soilEnsure soil pH is between 6 and 7.5. Preferred texture: Sandy Loam. Apply agricultural lime if your pH is below 6, ideally 30 days before planting.
- 2Plant at the right timeSelect certified garlic seed varieties suited to your altitude zone and plant at the onset of the rains.
- 3Apply basal fertilizerGarlic needs high nitrogen, medium phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
- 4Top-dressAt Week 3-4 after planting, apply 0.5 bag(s) per acre of CAN. Apply when shoots are 15cm tall. Stop nitrogen applications once bulbing begins.
- 5Monitor and harvestScout regularly for pests and disease. Expected yield is about 3,000 kg/acre at roughly KES 275/kg.
