Characteristics
Fast growing evergreen tree with a very cracked dark gray bark. Flowers in bunches facing up.
Location
Tolerates constant exposure to wind and is resistant to cold, although it can only develop properly in a warm climate; that is to say that it can tolerate night frosts only if the temperature rises significantly during the day.
Watering
Water abundantly in summer, letting it dry between waterings. In autumn and winter, water enough so that the soil does not dry completely.
Fertilization
During spring and summer.
Re-potting
Every 2 years, in early spring.
Substrate
A mixture of 6 parts of Akadama, with 4 parts of volcanic gravel can be used; otherwise Mistral Bonsai TERRABONSAI can also be used.
After transplanting it is convenient to water with a solution of VITABONSAI from Mistral Bonsai, to accelerate the recovery of the tree.
Pruning and pinching
Pruning
Perform pruning shortly after transplanting in spring, before vegetative growth begins.
Pinching
Throughout the growing season, we can pinch slightly.
Wiring
During spring
