Tea farming guide — Kenya

Soil requirements

Growing conditions for Tea

Tea does best with 1,100–2,500 mm of rainfall a year at 1,500–3,000 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 Tea in Kenya

To achieve maximum yields when farming tea in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 4.5 to 6. 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. Tea has a high nitrogen requirement, medium phosphorus requirement, and medium 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 NPK 26:5:5 at Continuous (every 3 months)), ensures high crop quality and protects your overall farm investment.

How to grow tea in Kenya

1. 1
   Prepare the soil

   Ensure soil pH is between 4.5 and 6. Preferred texture: Clay. Apply agricultural lime if your pH is below 4.5, ideally 30 days before planting.
2. 2
   Plant at the right time

   Plant tea during Long Rains (Plucking & NPK Fertilizer Application–Pest Monitoring & Top Dressing) or Short Rains (Plucking & Top Dressing–Fertilizer Application) or Dry Season (Pruning & Canopy Management–Recovery Plucking), timed to the start of the rains.
3. 3
   Apply basal fertilizer

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

   At Continuous (every 3 months), apply 1 bag(s) per acre of NPK 26:5:5. Apply evenly around root zone. Avoid lime — tea prefers acidic soil.
5. 5
   Monitor and harvest

   Scout regularly for pests and disease. Expected yield is about 2,200 kg/acre at roughly KES 25/kg.

Planting calendar

Establishment timeline

Tea is a perennial — it takes ~4 years to first harvest before your first crop, then yields for many years. Here is what each stage involves.

1. Year 0 — Planting · Long rains

   Plant VP cuttings at 1.2 × 0.6 m into well-prepared holes with phosphate; provide shade and mulch.

2. Years 1–2 — Frame formation

   Formative pruning / pegging to build a spreading plucking table; weed and apply NPK 25:5:5. Do not pluck yet.

3. Year 3 — Tipping-in

   Bring bushes up to plucking-table height; take a first light pluck.

4. Year 4 — First full plucking

   Regular 7–14 day plucking rounds begin; full fertilizer programme.
