The Ultimate Guide to Coriander (Dhania) Farming in Kenya

With the rising demand for aromatic foods in Kenya, many farmers are moving away from traditional crops and embracing spicy herbs like coriander (Dhania), lemongrass, and hibiscus. Among these, coriander has emerged as a popular and profitable choice, both for home consumption and for local urban markets.

Coriander herb

Coriander is a versatile herb with tender leaves, fragrant seeds, and a host of health benefits. Its unique features—white flowers, aromatic leaves, and pungent seeds- make it a favorite for gardeners and chefs alike. Additionally, coriander attracts birds and butterflies, is deer-resistant, and is easy to grow, making it an ideal herb for both small-scale and commercial farming.

Why Grow Coriander?

Coriander farming offers several advantages:

• Quick returns: Coriander matures in as little as 45 days, making it a high-turnover crop.

• High profitability: A small garden measuring 3 x 5 meters can generate around KSh 15,000 in just 1.5 months.

• Dual use: Leaves are used fresh in cooking, while seeds are processed into spices and curry powders.

• Easy to grow: Requires minimal inputs and is adaptable to different soils.

Requirements for Coriander Farming

To successfully cultivate coriander, you will need:

• Soil: Well-drained alluvial or light sandy loam, rich in organic matter

• Seeds: High-quality coriander seeds

• Water: Regular irrigation

• Sunlight: Full sun exposure for optimal growth

• Tools: Knife, trowel, garden hoe, and watering can

Ideal Growing Conditions

Coriander thrives in mild, warm-to-cool climates. It prefers well-drained soil enriched with organic matter. Avoid waterlogging, as excess moisture can harm the plants.

How to Plant Coriander

1. Sowing: Plant seeds in drills 30cm apart for leaf production and 50cm apart for seed production.

2. Depth: Sow seeds 2.5–3.5cm deep.

3. Germination: Seeds typically emerge within 10 days.

4. Thinning: Thin seedlings when they are 5–7cm tall to maintain spacing of 10–15cm.

5. Watering: Ensure even distribution of moisture throughout the growing season, particularly for leaf production.

Harvesting Coriander

• For leaves: Harvest the largest plants first to encourage growth of smaller ones for later harvests.

• For seeds: Wait about three months until flowers have dried. Cut stems, pile them in the field for further ripening, then thresh to collect seeds.

Common Pests and Diseases

1. Bacterial leaf spot: Water-soaked spots on leaves turning dark brown/black.

2. Soft rot: Brown, soft lesions near the base of leaves.

3. Powdery mildew: White powdery growth on leaves and stems.

4. Damping-off: Seedlings rot before or shortly after emergence.

5. Carrot motley dwarf (CMD): Yellow/red leaves and stunted growth.

6. Root knot nematode: Galls on roots cause yellowing and reduced vigor.

7. Armyworm: Holes in foliage; larvae feed heavily at night.

8. Cutworms: Stem damage near the soil line; active at night.

9. Aphids: Sticky honeydew and stunted or yellow leaves.
