Pinus thunbergii belongs to the genus Pinus, also known as Japanese black pine. This beautiful pine is characterized by delicate needle-like green leaves that always grow in pairs. In spring, Thunbergii produces small reddish flowers and later grows small brown cones. Black pine is one of the most hardy bonsai tree species because it can withstand almost any relentless, harsh environment. It has an irregularly shaped gray bark that turns black as the tree ages. Japanese black pines live best in full sun and high temperatures, but the roots may be burnt in bonsai pots. Therefore, it is advisable to protect the bowl from the hot summer sun. The color of the leaves is lighter green if the tree is grown in a sunny place, but deep green if it is grown in half or in full shade.The plant tolerates mild drought well, although it is better to keep Japanese black pine slightly moist. Excellent drainage should be provided to minimize the possibility of root rot, so Kiryuzuna + Akadama + Pumis planting medium mixed with a little activated carbon is recommended. The Japanese blackbird does not require fertilization in an unusual way. Nevertheless, the use of BioGold or a similar nutrient-rich preparation (e.g., fish emulsion) between mid-spring and early autumn is evaluated as a bonsai. Pruning the tree in late fall and early winter decided to perfect it to prevent or minimize “moisture bleeding,” moisture loss. After cutting, use wound dressing to treat exposed, open wounds. Black pine bonsai become stressful due to pruning, so it is necessary to keep them in the shade / diffused light for two weeks after pruning.
