Lime Kaffir

• Native to Southeast Asia, particularly Thailand, Indonesia, and Malaysia, where it's been cultivated for centuries. The scientific name reflects its Indonesian origins.
• Produces distinctive double-lobed leaves that release intense citrus fragrance when crushed or torn. The bumpy, dark green limes are primarily grown for zest rather than juice.
• Slow-growing evergreen tree that can reach 3-5 metres in ideal conditions. Thorny branches and glossy leaves make it an attractive ornamental as well as culinary plant.
• Highly valued by chefs and home cooks for authentic Thai, Indonesian, and Malaysian cuisine. Both fresh and dried leaves are used in cooking.

• Water when top 2cm of soil is dry, typically every 2-3 days in summer and weekly in winter. Check soil moisture regularly rather than following strict schedules.
• Position in full sun location receiving 6+ hours direct sunlight daily. Protect from strong afternoon sun in extremely hot climates.
• Plant in well-draining citrus potting mix or add compost and sand to heavy soils. Ensure pH stays between 6.0-7.5 for optimal nutrient uptake.
• Feed with citrus fertiliser every 6-8 weeks during growing season (spring to autumn). Apply organic compost annually in early spring.
• Prune lightly after harvest to maintain shape and remove dead or crossing branches. Pinch growing tips to encourage bushy growth.
• Protect from frost and temperatures below 10°C by moving containers indoors or using frost cloth.

• Provide full sun for at least 6 hours daily for best leaf production and fruit development. Morning sun with afternoon protection works well in hot climates.
• Water deeply when top 2cm of soil feels dry, more frequently in summer and less in winter. Maintain consistent moisture but never waterlogged conditions.
• Use well-draining citrus potting mix or sandy loam soil with good organic content. Ensure containers have adequate drainage holes.
• Maintain humidity around 50-60% and protect from strong winds and frost. Ideal temperature range is 15-30°C year-round.

• Scale insects and aphids can attack new growth - spray with horticultural oil or insecticidal soap. Check regularly under leaves and on stems.
• Citrus canker causes brown spots on leaves and fruit - remove affected parts immediately and avoid overhead watering. Ensure good air circulation around the plant.
• Root rot from overwatering causes yellowing leaves and stunted growth - improve drainage and reduce watering frequency. Repot in well-draining citrus potting mix if severe.
• Citrus leaf miner creates silvery trails in leaves - prune affected growth and apply sticky traps during warm months.
