Kaffir Lime (Citrus hystrix)

This species of Indonesian lime has highly aromatic leaves which, along with the rind, are essential ingredients for creating the authentic flavour of Thai cuisine. Kaffir limes have curious, 'double' leaves and strong spines. The heavily dimpled fruit, which ripen to a yellow colour, aren't quite as juicy as most citrus. While some describe their tart juice as strongly flavoured, others find it ideal for flavouring food and drinks.

Plant Care

• Soil: Prefers well-draining, fertile soil with a pH between 6.0 and 7.0.
• Watering: Water deeply and regularly, allowing the soil to dry slightly between waterings.
• Temperature: Thrives in temperatures between 15°C and 30°C. Protect from frost.
• Light: Full sun is essential for optimal growth and fruit production.
• Fertilising: Use a citrus-specific NPK fertilizer with micronutrients, typically a ratio like 6-3-3, every four to six weeks during the growing season.
• Pruning: Prune to shape, improve airflow, and remove dead or diseased branches in late winter or early spring.
• Mulching: Apply a layer of organic mulch around the base to help retain moisture and suppress weeds, but keep it away from the trunk.
• Pest Control: Monitor for citrus pests such as scale, mites, and citrus leaf miner. Treat with appropriate insecticides or natural remedies.
• Flowering and Fruiting: Blooms in spring with fruit development continuing through summer and into fall, depending on the variety.
• Potting: Suitable for container growing, especially dwarf varieties. Ensure containers have good drainage.
• Feeding Regime: Increase feeding frequency during peak growing and fruiting periods.
