In the native countries, the camphor tree exceeds 40 meters in height while at different latitudes, in full vegetative development, it reaches a maximum of 20-30 meters.

In fact, in centuries-old trees, the aerial roots, as large as branches, form wonderful sculptures.

Exposure

She loves the heat, therefore, to obtain abundant flowering and abundant berries. If planted in partial or total shade, it slows down growth, produces few flowers and few berries. Adult trees do not fear low temperatures even if they persist for long periods in fact they tolerate temperatures below -10 ° C and short frosts very well. The foliage of young specimens is conspicuously ruined with late frosts.

Ground

It is a perennial and evergreen plant that grows in any type of soil even if it prefers soft, loose, well-drained ones with an acid pH. A compact and not very water permeable soil could cause root rot especially if the specimen is young.

Watering

It is also tolerant to drought. Generally, the well-rooted and planted camphor tree is satisfied with the rains and we intervene with an abundant supply of water in summer or during the flowering period if the climate is particularly dry. Regular and frequent watering should be practiced only if the plant is still young or has recently been planted in order to favor a more rapid rooting of the root system in the new home. Irrigation must be suspended in the autumn-winter period.

Fertilization

In the first years of the plant it needs an organic fertilizer buried in the well-worked soil. Subsequently, biennial or triennial fertilizations with a fertilizer for green plants are sufficient, every 2-3 years during autumn or at the end of winter.

Propagation by cuttings

Semi-woody cuttings taken from young branches with well-sharpened and disinfected shears are used. They are rooted in a mixture of sand and peat sand kept constantly humid until rooting has taken place.
Either way, if planted in optimal soil, growth is very fast.

Propagation by sucker

The camphor tree emits numerous well-rooted suckers on its feet that can be taken from the ground with the roots and immediately replanted in a sunny and spacious area. The best time for this method is late spring.

Planting or planting

Cinnamomum camphora settle permanently in spring or autumn. The soil intended to accommodate the plant must be lightened with peat, pumice or sand and enriched with mature organic fertilizer. Since the root system of this plant develops vigorously even on the surface, planting it near homes, pipes or tiled areas is not recommended.

Pruning

The camphor tree does not need frastic pruning. In general, only dry branches are pruned, those that are too low and those broken by the wind are shortened a little.
