Capsicum Farming in Kenya: Hoho, Bell Peppers, Colours and Export

Capsicum farming in Kenya — known locally as hoho — has become one of the most attractive high-value vegetable enterprises, especially as demand grows for coloured bell peppers from supermarkets, hotels, and exporters. Whether grown as green hoho for the local market or as premium red and yellow peppers under greenhouse, capsicum rewards good agronomy with strong margins. This guide covers open-field and greenhouse production, variety and colour choice, pests, harvesting, and where to sell.

Where capsicum grows in Kenya

Capsicum is a warm-season crop that does best at moderate altitudes with temperatures of 18–30°C, plenty of sunshine, and protection from extreme heat and cold. It is grown across many counties, including:

• Central Kenya — Kiambu, Murang'a, Kirinyaga, and Nyeri, often under greenhouse.
• Rift Valley — Nakuru, Kajiado, and Narok with irrigation.
• Eastern — Meru, Embu, and Machakos.
• Western and Nyanza — around Kisii, Kakamega, and Kisumu.

Capsicum needs deep, fertile, well-drained loam at pH 5.5–6.8 and consistent moisture. It is sensitive to both drought and waterlogging, so irrigation — usually drip — is strongly recommended for reliable quality and yield.

Varieties and the colour premium

The biggest profit lever in capsicum is colour. Green hoho is the immature stage; left on the plant, most varieties ripen to red, yellow, or orange, becoming sweeter and far more valuable.

Variety	Type	Colour at ripeness	Best for
California Wonder	Open-pollinated	Green to red	Local green hoho, open field
Yolo Wonder	Open-pollinated	Green to red	Reliable field variety
Admiral F1	Hybrid	Red	Greenhouse, premium/export
Commandant F1	Hybrid	Green	High yield, uniform hoho
Golden hybrids	Hybrid	Yellow	Premium coloured market

Coloured peppers can fetch two to four times the price of green, but they occupy the plant longer and demand better disease control. If you have a greenhouse and buyers, coloured hybrids pay best; for a quick, lower-cost local crop, green hoho from California Wonder or Commandant F1 works well.

Open field versus greenhouse

• Open field — cheaper to enter, suits green hoho, higher exposure to pests, weather, and disease.
• Greenhouse — higher establishment cost but far higher yields per square metre, cleaner and more uniform fruit, better pest and disease control, dependable coloured peppers, and export-grade quality. A greenhouse also extends the season and shelters the crop from hail and heavy rain.

A common path is to start open-field, learn the crop and market, then reinvest into a greenhouse to chase the coloured and export premium.

Nursery, planting and crop care

Sow seed in trays or a raised nursery bed under shade netting to exclude aphids, whiteflies, and thrips that carry viruses. Transplant sturdy seedlings with 4–6 true leaves after 5–7 weeks. Space at 45–60cm between plants and 60–75cm between rows, on raised beds with driplines laid.

• Incorporate manure and apply a basal DAP or planting fertiliser (soil test first).
• Keep soil evenly moist — capsicum hates both drought and waterlogging.
• Top-dress with CAN and feed potassium and calcium through the drip as fruit sets; calcium prevents blossom end rot.
• Stake or trellis plants — heavy coloured fruit left to ripen will snap unsupported branches.
• Remove the first few flowers to build a strong frame, and prune for airflow in greenhouses.

Pests and diseases

• Aphids, thrips, and whiteflies — sap feeders that also spread viruses; control early and use screened nurseries.
• Spider mites — worse in hot, dry conditions; look for stippling and webbing.
• Bollworm / fruit borer — larvae bore into fruit; scout and spray at first sign, rotating chemistry.
• Bacterial wilt — no cure; use clean seed, rotate away from tomatoes, potatoes, and peppers, and rogue infected plants.
• Powdery mildew and damping off — manage with airflow, clean nursery media, and preventive fungicides.
• Blossom end rot — a calcium and moisture-stress disorder, not a pest; fix with steady watering and calcium.

Harvesting and post-harvest

Green hoho is ready about 2.5–3 months after transplanting, once fruit are full-sized, firm, and glossy. For red or yellow peppers, leave fruit to ripen on the plant — it takes longer but earns far more. Cut fruit with a short stalk, handle gently to avoid bruising, and keep it cool and shaded. Grade by size and colour into clean crates; uniform, well-coloured fruit reaches supermarkets, hotels, and exporters who pay premium prices. A healthy crop keeps producing for several months, so harvest repeatedly.

Yields and economics

A healthy open-field capsicum crop yields roughly 10–20 tonnes per acre, while a well-run greenhouse can far exceed that per unit area because plants are more productive and the season is longer. Green hoho farm-gate prices commonly range from KES 30 to KES 90 per kg, while red and yellow peppers can reach KES 120–250 per kg or more in tight supply, which is why the colour premium dominates the economics. Input costs — seedlings, manure, fertiliser, staking, irrigation, and a disciplined spray programme — are moderate for open field and higher for greenhouse, but the repeated harvests over several months spread those costs across a long earning window. The keys to profit are keeping the plants disease-free so they keep producing, and grading fruit so the best reaches premium buyers.

Markets for capsicum in Kenya

• Local wholesale and retail markets — steady demand for green hoho.
• Supermarkets, hotels, and restaurants — reliable buyers of graded green and coloured peppers.
• Exporters — coloured bell peppers are exported to regional and overseas markets by certified growers; meet the buyer's quality and traceability standards.
• Agrisoko marketplace — list your capsicum to reach bulk buyers and traders across Kenya.

Because capsicum trades alongside other vegetables, it pays to watch the wider market. Compare demand on the Agrisoko market intelligence dashboard and related vegetable price signals such as the tomato price page before you commit a load, so you sell when prices favour you.

Key takeaways

• Colour is the profit lever — red and yellow peppers earn far more than green hoho.
• Greenhouses deliver higher yields, cleaner fruit, and export-grade coloured capsicum; open field suits green hoho.
• Use screened nurseries, clean seed, and rotated chemistry to keep viruses and pests out.
• Grade by size and colour, and time sales to strong-demand windows.
