Black pine seedlings are commonly propagated by sowing seeds and cuttings. Sow the seeds, sow them immediately after picking them in a month, and germinate in about a day. Cuttings are carried out in spring and autumn. Dormant branches are selected in spring and semi-lignified twigs are selected in autumn. The best time to transplant is in spring. Small seedlings need to be brought with soil, and large seedlings with soil balls. They can also be planted in pots. Water thoroughly after planting. Keep the soil moist during the growing season. In the high temperature season of midsummer, it needs to be placed in a semi-shady place for maintenance. Fertilize once a month. In winter, pay attention to cold protection for potted plants. The pots can be buried in the soil and watering should be reduced.
