Camphor prefers fertile sandy soil. It will tolerate a pH anywhere in the range of 4.3 to 8. The roots are very sensitive to disturbance. They may extend far from the trunk of the tree, and can readily be identified by their characteristic odor.
Light: Camphor will grow in full sun or partial shade.
Moisture: Camphor tree does not do well in wet soils. Established trees are tolerant of drought.
Hardiness: USDA Zones 8 - 10. Hardened off camphor trees can survive freezes down to 10-15ºF (-12 - -9ºC), but new growth will suffer freeze burn when the temperature drops below 32ºF (0ºC) and branches will die back from temperatures in the low twenties.
Propagation: Camphor seed does not remain viable for long and should be planted in the greenhouse as soon as it ripens. Remove the fruit pulp first. At 68ºF (20ºC), germination will take 1-6 months. Cuttings of semiripe side shoots can be rooted in a warm humid place in midsummer. Pieces 2-3 in (5.1-7.6 cm) long with a heel work best.
