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.
They prefer full sun but in the warm areas of the country will handle some shade.
Need watering regularly especially during summer. Water newly planted trees once or twice per week deeply.
To ensure successful fruiting, plant in well-drained fertile soil. Incorporate a good compost and keep mulched.
Citrus are heavy nutrient feeders, use a high nitrogen NPK fertiliser. Apply 200g at the drip line (2/3 in spring and 1/3 in summer) increasing this by 200g per year until you are applying 2kg. Apply manure in the autumn spread under the tree with mulch.
Not very wind tolerant but reasonably tolerant to salty marine conditions.
Cold tolerant to - 5°C. More hardy once established.

Citrus are not trained to any particular shape, some varieties do not need any shaping at all. Prune to shape if necessary and any dead or diseased branches. They will tolerate heavy cutting back. Also remove any sucker growth.
