Pick-up of five-needle pine is generally carried out in April and MayIt is best to take the buds when extracting 2 cm to 3 cm. If the bud is too short, it is not only inconvenient to operate, but also easy to hurt the base of the bud; The buds are too long and often have begun to form lignification, which is not easy to handle.

The cones mature in the autumn of the following year, and the scales split to scatter the seeds, which have thin wings. The umbilicus of the scales has short spines. It is native to the southern coast of Japan and Korea.

It is mainly reproduced sexually, but it can also be reproduced with vegetative reproduction. Among them, branch cuttings and coniferous bunching cuttings can be successful, but the difficulty is relatively large, and the production is still dominated by sowing and raising seedlings. Seedbed sowing and container seedling applications are common.

Cultivation environment: Black pine is drought tolerant, and can be stored all year round in the courtyard on the slope and balcony, on the platform, where there is sufficient sunlight and air flow. However, small bonsai should not be exposed to strong light in midsummer.

During the leaf picking period, it is necessary to remove the old needles on the bud point of the plant, which can save the nutrients of Paikai for the plant, enhance the air permeability of the branch, expand the growth space of the bud point, and help the bud point germinate and grow in the spring of the next year.
