Seedling
4-8 weeksSmall sprouting with 2-4 cotyledons and first true leaves appearing
Keep soil consistently moist but not waterlogged. Provide bright indirect light. Protect from temperature fluctuations below 50°F.
Juvenile Growth
2-3 yearsYoung tree establishing root system with rapid stem elongation and increasing canopy coverage
Water regularly during growing season. Install support stake for wind protection. Begin light pruning to shape form. Fertilize monthly during warm season.
Establishment
3-5 yearsTree developing strong trunk, branching structure, and becoming more self-sufficient
Reduce watering frequency as drought tolerance increases. Prune to maintain shape and remove dead wood. Continue light feeding during growing season.
Maturity
10+ yearsFully developed canopy producing fragrant foliage, small white flowers in spring, and small blue-black berries
Minimal watering except during drought. Pruning mainly for maintenance and shape. Harvest leaves or wood for camphor extraction if desired.
Oil Production
Ongoing throughout tree's lifeMature tree with high concentration of camphor compounds in wood and leaves
Avoid over-harvesting which can stress the tree. Allow recovery between harvest seasons. Selective harvesting of branches does not significantly reduce vigor.

Harvest Tips
Camphor is traditionally harvested from mature trees (10+ years old) by felling and distilling the wood and leaves, though this is a commercial-scale operation. Home gardeners can harvest fresh leaves year-round for aromatic use. Cut branches for distillation ideally in late spring. Leaves can be dried and used fresh for their camphor scent.
Fun Facts
- 🌱 Camphor trees can live for 200-500 years or longer, with some specimens in Asia documented to be over 1000 years old. Some individual trees are considered sacred and protected monuments.
- 🌱 The tree's strong fragrance naturally repels many insects and microorganisms, which is why camphor wood resists decay and has been used for centuries in traditional shipbuilding in Asia.
- 🌱 Japan's national tree (at least ceremonially recognized in some regions), the camphor tree is so emblematic that several cities in Japan—including Nagasaki and Kakegawa—feature ancient camphor trees as landmark attractions.
