Tarragon: Small Herb, Big Profits

Tarragon (Artemisia dracunculus), a perennial herb with a distinctive anise-like flavor, is a high-value crop for Kenyan farmers due to its growing demand in culinary, medicinal, and fragrance markets. Known for its use in French cuisine, vinegars, and herbal remedies for digestion and sleep, tarragon is increasingly popular in urban centers like Nairobi, Mombasa, and Kisumu, particularly among high-end restaurants and health-conscious consumers.

Its export potential to Europe, Australia, and the Middle East is significant, with Kenya exporting Ksh 6 million worth of tarragon from January to July 2021. The Kenyan herb and spice market, including tarragon, was valued at $13.8 million in 2023, with a 26% annual growth rate driven by global demand for premium herbs.

A single acre yields 600–1,000 kg of fresh tarragon leaves annually, fetching Ksh 400–600 per kg locally and Ksh 2,500–3,000 per kg for dried tarragon in export markets (2025 estimates). Tarragon’s suitability for greenhouse cultivation, pest resistance, and multiple harvests (every 20–25 days for three years) make it ideal for smallholder farmers and investors.

This guide provides a practical, investment-focused roadmap, highlighting tarragon’s unique flavor, greenhouse suitability, and Kenya’s culinary and export markets.

Suitable Regions & Climate in Kenya

Tarragon thrives in warm, temperate climates with well-drained soils. In Kenya, the following regions are ideal:

• Central Kenya: Thika, Kiambu, and Murang’a, with altitudes of 1,200–2,000 meters and temperatures of 18–25°C, are optimal. Farmers like Jane Kamau in Thika supply tarragon to export markets.
• Rift Valley: Nakuru and Eldoret, with rainfall of 600–1,200 mm annually, support greenhouse cultivation.
• Coastal Regions: Mombasa and Kilifi, with volcanic soils and irrigation, are suitable for controlled environments.
• Eastern Kenya: Embu and Meru, with moderate rainfall, are viable with proper drainage.

Tarragon prefers full sun to partial shade and well-drained loamy or volcanic soils (pH 6.0–7.5), as found near Mt. Kenya. It is sensitive to waterlogging but tolerates moderate drought, making greenhouses ideal for humid areas like Mombasa. Central Kenya’s stable climate and access to export markets make it a prime region.

Recommended Varieties

Selecting the right tarragon variety ensures high flavor quality and yields. The following varieties are recommended for Kenya:

• French Tarragon: Sweet, intense anise flavor, ideal for culinary and export markets (preferred by Taste Kenya Exporters).
• German Tarragon: Slightly milder, suited for local restaurants and teas.
• Russian Tarragon: Hardy but less flavorful, used in low-input farms in Nakuru.
• KALRO Hybrid: Locally adapted with pest resistance, popular in Thika.

Farmers in Thika prefer French Tarragon for its premium flavor, as per KALRO.

Source certified cuttings or seedlings (Ksh 30–60 each) from nurseries like Seedfarm (+254712075915) or Organicfarm for export-quality stock.

Step-by-Step Production Guide

1. Site Selection and Soil Preparation:
   • Choose a site with full sun to partial shade and well-drained loamy soil (pH 6.0–7.5). Test soil for 2–3% organic matter content.
   • Clear weeds and incorporate 5–7 tons of compost or manure per acre. Add rock phosphate (40 kg per acre) to support leaf growth.
   • Adjust pH with lime (if acidic) or gypsum (if alkaline).
2. Planting:
   • Use certified cuttings (Ksh 30–60 each) or seedlings, as tarragon rarely sets viable seeds. Cuttings ensure faster establishment.
   • Plant in rows with 30 cm between plants and 50 cm between rows (25,000–30,000 plants per acre).
   • Insert cuttings 5–10 cm deep or transplant seedlings. Water lightly after planting.
3. Irrigation:
   • Apply 1 inch of water weekly during establishment (first 6–8 weeks). Drip irrigation is ideal for semi-arid areas like Nakuru, saving 30% water.
   • Once established, water every 10–14 days. Mulch with straw to retain moisture and suppress weeds.
4. Greenhouse Cultivation:
   • Use greenhouses to control humidity and pests, as practiced by Premier Seed’s farmers in Nakuru.
   • Harvest leaves every 20–25 days for three years, allowing 10–12 cycles annually.
5. Monitoring and Maintenance:
   • Pinch back flower buds to prolong leaf production. Remove weeds regularly to reduce competition.

Fertilizer/Feeding Needs

Tarragon requires moderate nutrition for optimal leaf production and flavor:

• Organic Matter: Apply 5–7 tons of compost or manure per acre at planting and annually. Compost teas (10 liters per acre monthly) enhance soil microbes.
• Inorganic Fertilizers: Use NPK 15-15-15 at 80 kg per acre, split into two applications (post-planting and pre-harvest). Supplement with nitrogen (15 kg per acre) for leafy growth.
• Foliar Feeds: Apply calcium and magnesium sprays every 6 weeks to improve leaf quality and aroma.
• Timing: Fertilize during dry seasons to avoid leaching, as practiced in Thika.

Farmers in Nakuru report 20–25% yield increases using compost and drip irrigation, per Organic Farm’s recommendations.

Pest & Disease Control

Tarragon’s aromatic compounds deter many pests, and its pest resistance is noted as a key advantage. Monitoring is still needed:

• Common Pests:
  • Aphids: Use neem oil (5 ml per liter) or plant marigolds as a repellent.
  • Spider Mites: Apply sulfur sprays and maintain soil moisture.
  • Whiteflies: Deploy yellow sticky traps or insecticidal soap.
• Common Diseases:
  • Powdery Mildew: Apply sulfur sprays and ensure good air circulation in greenhouses.
  • Root Rot: Ensure well-drained soils and avoid overwatering.
  • Rust: Prune affected leaves and apply copper-based fungicides.

Farmers in Thika reduce pest costs by 25% using greenhouses, as per KALRO and Premier Seed’s practices.

Harvesting & Handling

• Timing: Harvest begins 45 days after planting, with peak yields from year 1. Cut leaves every 20–25 days for three years, typically April–June and October–December.
• Method: Use clean scissors to cut stems 5–10 cm above the base early in the morning to preserve flavor. Avoid over-harvesting to sustain regrowth.
• Post-Harvest: Wash fresh leaves for local markets or dry in a shaded, ventilated area for 5–7 days for export. Store dried leaves in airtight containers with moisture content below 10%. Proper post-harvest handling is critical to meet phytosanitary export standards.
• Yield: Expect 600–1,000 kg of fresh leaves per acre annually (180–300 kg dried).

Processors like Taste Kenya Exporters use solar dryers to ensure export-quality leaves, cutting drying time by 40%.
