Citrus hystrix

Seedling
6-8 weeksYoung tree develops true leaves with the characteristic double-lobed shape; still tender and establishing root system
Keep soil consistently moist but not waterlogged. Provide bright indirect light initially before transitioning to full sun. Protect from wind and temperature fluctuations.
Juvenile Vegetative
1-3 yearsTree grows upright with increasingly dark green foliage; developing strong branch structure but no flowers yet
Allow full sun exposure. Prune to encourage bushy shape if desired. Feed with balanced citrus fertilizer monthly during growing season. Tree may take 2-3 years to flower.
Flowering
3-6 weeksSmall white or pale pink fragrant flowers appear, typically in spring; flowers may occur in clusters along branches
Ensure consistent watering during flowering. Apply citrus-specific fertilizer higher in potassium to support fruit set. Avoid moving the tree or major pruning during bloom.
Fruiting & Development
4-6 monthsSmall green bumpy fruits develop and gradually increase in size; fruits take several months to mature, turning yellow-green when ripe
Thin fruit if overcrowded to encourage larger specimens. Maintain regular watering and feeding. Fruits are ready when fragrant and slightly soft when squeezed.
Harvest & Rest
OngoingRipe fruits harvested; tree continues to produce new leaves throughout the year in warm climates
Harvest ripe fruits regularly to encourage continued production. Reduce watering and feeding slightly in winter months. Prune dead or crossing branches.

Harvest Tips
Harvest leaves year-round by pinching or cutting the aromatic double-lobed leaflets; younger leaves are more tender and fragrant. For fruit, wait until they are yellow-green and fragrant, typically 4-6 months after flowering. Pick fruit when slightly soft to pressure; unripe fruit is very acidic. Fruit does not continue to ripen after harvest, so allow full maturation on tree.
Fun Facts
- 🌱 Makrut lime is sometimes called 'kaffir lime,' though 'kaffir' is considered offensive in some regions; Southeast Asian cooks prefer the term 'makrut,' derived from the Thai name.
- 🌱 The intensely aromatic leaves contain more volatile oils than the fruit itself and are more commonly used in cooking than the actual citrus fruit.
- 🌱 Makrut lime trees can live 50+ years in ideal conditions and become quite large (15-20 feet), making them long-term garden investments in warm climates.
