Section 2: Optimal Growing Conditions
Climate Requirements
| Factor | Ideal Condition |
|---|---|
| Temperature | 15-20°C (tolerates 5-30°C) |
| Altitude | 800-2,200m above sea level |
| Rainfall | 600-1,000mm annually |
| Sunlight | 6-8 hours daily |
Pro Tip: Light frost enhances sweetness, while temperatures above 25°C cause bitter leaves.
Soil Preparation
- Test soil pH (Ideal: 6.0-7.0)
- Till to 18-inch depth
- Amend with organic matter (20kg compost per sqm)
- Create raised beds (Improves drainage)
Common Mistake: 78% of Kenyan kale farmers skip soil testing, resulting in 40% lower yields.

| Winterbor | Frost-resistant, long harvest | 35kg/plant | Cold highlands |
2024 Recommendation: Hybrid varieties like Green Dream F1 offer 40% higher yields than traditional seeds.
Section 4: Step-by-Step Planting Guide
1. Seedbed Preparation
- Spacing: 30cm between plants, 60cm between rows
- Sowing Depth: 1cm
- Germination: 5-7 days
Cost-Saving Hack: 1kg seeds plants 1 acre (vs. 3kg for traditional varieties)
2. Fertilization Schedule
| Growth Stage | Fertilizer Type | Application Rate |
|---|---|---|
| Planting | DAP (18:46:0) | 50g per planting hole |
| 2 Weeks | CAN (26% N) | 10g per plant |
| Monthly | Organic compost | 5kg per sqm |
Organic Option: Safi Biozyme increases yields by 25% (Tested by KALRO)
3. Irrigation Management
- 💧 Drip irrigation (Saves 60% water vs. flooding)
- ⏲️ Watering schedule:
- Dry season: 3 times weekly
- Rainy season: Only when soil dries
Section 5: Pest & Disease Control
Major Threats
| Pest/Disease | Symptoms | Organic Control |
|---|---|---|
| Aphids | Curled leaves | Neem oil spray |
| Diamondback Moth | Holes in leaves | Bt spray |
| Black Rot | Yellow V-shaped lesions | Crop rotation |
Prevention Strategy: Intercrop with onions/garlic to repel pests naturally.
Section 6: Harvesting & Post-Harvest
Optimal Harvesting
- ✂️ First pick: 4-6 weeks after planting
- Method: “Cut-and-come-again” (Harvest outer leaves)
- Best Time: Early morning (Higher moisture content)
Post-Harvest Handling
- Cool immediately (Reduces wilting)
- Bundle in 1kg packs (Market preference)
- Store at 4°C (Lasts 2 weeks)
Value-Addition Idea: Process into kale powder (Sells for KSh 800/100g)
Section 7: Marketing Strategies
Where to Sell
| Market | Price Range (per kg) | Advantage |
|---|---|---|
| Local markets | KSh 20-40 | Daily sales |
