Pineapple farming guide — Kenya

Soil requirements

Growing conditions for Pineapple

Pineapple does best with 1,000–1,500 mm of rainfall a year at 0–1,800 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 Pineapple in Kenya

To achieve maximum yields when farming pineapple in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 4.5 to 6.5. 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. Pineapple has a medium nitrogen requirement, low 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 Months 3, 6 and 9 after planting), ensures high crop quality and protects your overall farm investment.

How to grow pineapple in Kenya

1. 1
   Prepare the soil

   Ensure soil pH is between 4.5 and 6.5. Preferred texture: Sandy Loam. Apply agricultural lime if your pH is below 4.5, ideally 30 days before planting.
2. 2
   Plant at the right time

   Plant pineapple during Long Rains (Ratoon sucker planting & Basal NPK–Fruit Development Monitoring) or Short Rains (Top Dressing & Weed Control–Fruit Fill & Disease Scouting) or Dry Season (Harvesting & Ratoon Management–New Sucker Selection & Planting), timed to the start of the rains.
3. 3
   Apply basal fertilizer

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

   At Months 3, 6 and 9 after planting, apply 1 bag(s) per acre of CAN. Split-apply at the leaf axils; add Sulphate of Potash (not MOP — pineapple is chloride-sensitive)
5. 5
   Monitor and harvest

   Scout regularly for pests and disease. Expected yield is about 25,000 kg/acre at roughly KES 35/kg.

Planting calendar

Establishment timeline

Pineapple is a perennial — it takes ~1.5 years to first harvest before your first crop, then yields for many years. Here is what each stage involves.

1. Month 0 — Planting

   Plant suckers or slips at 30 × 60 cm on beds with basal NPK; mulch.

2. Months 1–10 — Vegetative

   Weed, foliar feed, and top-dress to build leaf mass.

3. Months 10–12 — Flower induction

   Force flowering (ethephon/ethylene) for a uniform, plannable crop.

4. Months 15–18 — First harvest

   First fruit matures; a ratoon crop follows from the same plant.
