This article explores the key aspects of lemongrass farming in Kenya, including suitable growing areas, varieties grown, cultivation practices, and the lucrative market for this versatile crop.
Ideal Lemongrass Growing Areas in Kenya
Lemongrass thrives in warm and humid climates with adequate rainfall. In Kenya, the following regions provide ideal conditions for lemongrass farming:
- Western Region: Known for its fertile soils and moderate climate, counties like Kakamega, Bungoma, and Busia are excellent for lemongrass cultivation.
- Coastal Region: The warm and humid conditions in counties like Kilifi and Kwale make them ideal for lemongrass farming.
- Central Region: Counties like Murang’a, Kiambu, and Nyeri are favorable for lemongrass due to their well-drained soils and consistent rainfall.
- Rift Valley: Parts of the Rift Valley, especially in Kericho, Nakuru, and Bomet, offer optimal climatic conditions for growing lemongrass.
Varieties of Lemongrass Grown in Kenya
There are several varieties of lemongrass cultivated in Kenya, each with distinct characteristics and uses. The most commonly grown varieties include:
- East African Cymbopogon Citratus: Popular in Kenya, this variety is used for essential oil production and as a spice.
- Cymbopogon Martini: Known for its high oil content, it is widely used in the cosmetic and pharmaceutical industries.
- Cymbopogon Winterianus: A fast-growing variety that thrives in tropical climates, often used in the production of citronella oil.
- Cymbopogon Flexuosus: This variety is valued for its high yield and resilience, making it a favorite among farmers.
- West Indian Cymbopogon Citratus: A variety known for its intense citrus flavor and commonly used in the food industry.
Ecological Requirements for Lemongrass Farming
For successful lemongrass farming, certain ecological conditions must be met:
- Soil: Lemongrass prefers well-drained, slightly acidic soil with a pH range of 5.5 to 7.5. Sandy loam soils are ideal for its growth.
- Climate: A warm and humid climate with temperatures between 20°C and 35°C is necessary for optimal growth.
- Rainfall: Adequate rainfall or a reliable irrigation system is required to ensure the healthy growth of lemongrass.
Land Preparation
Before planting, the land must be prepared by clearing weeds and tilling to a fine texture. Proper land preparation helps improve soil structure and nutrient availability. Adding well-decomposed organic manure during this stage is essential to enhance soil fertility and structure.
Planting Lemongrass
Lemongrass can be propagated either through seeds or stem cuttings, with the latter being more popular among Kenyan farmers. Here’s a brief guide to planting lemongrass:
- Stem Cuttings: Prepare rows in the field with a spacing of 60cm between rows and 30cm between plants. Plant the cuttings in well-prepared soil.
- Seeds: Sow seeds directly in the field and cover them with a thin layer of soil. Water them regularly, and germination will begin within 14 days.
Pests and Diseases
While lemongrass is relatively hardy, it is still susceptible to certain pests and diseases. Common pests include aphids, mites, and grasshoppers, while leaf rust and fungal infections are the most prevalent diseases. To prevent and control these issues, farmers are encouraged to:
- Use recommended pesticides and fungicides.
- Plant pest- and disease-resistant varieties.
- Maintain proper field sanitation by regularly clearing weeds and debris.
Harvesting Lemongrass
Lemongrass takes about 6 to 8 weeks to mature, depending on the variety and growing conditions. Harvesting involves cutting the stalks at the base using sharp tools. With proper care, farmers can harvest between 5 to 10 tons of lemongrass per acre, depending on the variety and soil fertility.
