Lemon farming guide — Kenya

Soil requirements

Growing conditions for Lemon

Lemon does best with 600–1,500 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 Lemon in Kenya

To achieve maximum yields when farming lemon 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. Lemon 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 Three times per year), ensures high crop quality and protects your overall farm investment.

How to grow lemon in Kenya

1. 1
   Prepare the soil

   Ensure 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.
2. 2
   Plant at the right time

   Plant lemon during Long Rains (Transplanting & Basal–Flowering & Fruit Set) or Short Rains (Transplanting & Basal–Fruit Development), timed to the start of the rains.
3. 3
   Apply basal fertilizer

   Lemon needs high nitrogen, high phosphorus, and high potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
4. 4
   Top-dress

   At Three times per year, apply 0.6 bag(s) per acre of CAN. Split citrus feeding across the year. Foliar zinc and manganese keep leaves healthy.
5. 5
   Monitor and harvest

   Scout regularly for pests and disease. Expected yield is about 10,000 kg/acre at roughly KES 50/kg.

Planting calendar

Establishment timeline

Lemon is a perennial — it takes ~3 years to first harvest before your first crop, then yields for many years. Here is what each stage involves.

1. Year 0 — Planting

   Plant grafted trees 5–6 m in holes with manure + phosphate; stake and water.

2. Years 1–2 — Framework

   Formative prune, weed ring, irrigate, control greening and canker.

3. Year 3 — First fruit

   First flowering and light crop; apply NPK + micronutrients.

4. Years 4+ — Building yield

   Bears fruit through much of the year once established.
