🌱 A Complete Guide to Planting SL Coffee Seedlings in Kenya

By Kenya Coffee School & Barista Mtaani

Kenya’s famous SL varieties (SL28 & SL34) are globally prized for their cup quality—but achieving that excellence starts with proper planting and care from day one.

This guide walks you through what to do immediately after planting and how to manage your coffee all year round for maximum yield and quality.

☕ 1. Before You Plant (Preparation is Everything)

✔ Choose well-drained, fertile soil (slightly acidic pH 5.5–6.5)
✔ Dig planting holes: 2 ft x 2 ft x 2 ft
✔ Mix topsoil with:

• Well-decomposed manure (20–30 kg per hole)
• Phosphate fertilizer (DAP or TSP)

✔ Spacing:

• 2m x 2m (intensive farming)
• 2.5m x 2.5m (recommended for airflow & disease control)

✔ Plant at the onset of rains (March–May or Oct–Dec)

🌿 2. What To Do Immediately After Planting

💧 Watering

• Water immediately after planting
• Continue watering 2–3 times per week if rains are insufficient

🌱 Mulching

• Apply dry grass or leaves around the base
• Helps retain moisture and control weeds

🌳 Shade Management

• Provide temporary shade (banana leaves or shade nets)
• Protects young seedlings from heat stress

🚫 Pest Prevention (Early Stage)

• Spray preventive fungicide (e.g., copper-based)
• Monitor for leaf miners and aphids

🪴 Staking & Protection

• Use sticks to support seedlings against wind
• Fence or protect from livestock

🌾 3. First 3–6 Months (Establishment Phase)

✔ Weed regularly (every 2–3 weeks)
✔ Maintain mulch cover
✔ Light pruning—remove dead or weak shoots

Fertilizer (Early Feeding)

• Apply CAN (Calcium Ammonium Nitrate) after 3 months
• Small amounts: ~50g per plant
• Apply in a ring around the plant (not touching stem)

🌳 4. Year-Round Coffee Management Calendar

🌦️ Rainy Season (March–May / Oct–Dec)

🌱 Fertilization

• Apply:
  • NPK (17:17:17 or 20:10:10) for growth
  • Organic manure to improve soil health

🌿 Weed Control

• Keep field clean—reduce competition for nutrients

🦠 Disease Control
