Black pine stumps are mainly excavated from mountainous areas. The stumps growing on the sandy slopes of flat and barren cliffs should preferably have old trunks, short and curved stems and bare roots. The excavation time should be between slight cold and severe cold. When digging, the roots should be intact and muddy, so that it is easy to survive. Newly dug trees should be planted in cultivation pots, cultivated for 1 year, and then planted in ornamental pots. The decorative basin can be of medium-deep type. Loose, neutral or slightly acidic topsoil, such as mountain soil and humus soil, mixed with a small amount of coarse sand, should be used as basin soil. Rotten pond soil is very suitable for planting black pine after being crushed by selenium. Newly dug stumps have been cultivated for 1 year. When changing pots, the stumps should be dug out of the original pots, and 2/3 of the old soil should be removed, so as to promote the stumps to take root and make them flourish. Roots that are too long, old, rotten and diseased should be cut off when turning over the old pot, and the pot should be turned over 23 months before the branches germinate. When potted, you can cut the pine branches with needles in half and cut off the roots that are too long. When serving, the roots should be stretched tightly, and the roots should not be hugged together. After planting, water it and place it in a cool and ventilated place. Modeling is mainly based on climbing, supplemented by scissors. The lower branches of the trunk Dozza into drooping branches, ups and downs, or tied into flat branches. The branches of the trunk are wheel-shaped, so the thick branches of 1 should be selected, and the upper and lower branches should be staggered to avoid parallel branches. Climbing and pruning are mostly carried out during the dormant period. Pruning during growth period can easily lead to turpentine flowing out of the wound and affect growth.
