In order to control the shape of black pine bonsai, it is best not to apply fertilizer at will, which will easily lead to overgrowth. Generally, more fertilizer should be applied when pruning new buds, and it is best to fertilize first and then prune new buds, so as not to affect their germination again.

Cut a cutting with a length of 8 ~ 10 cm from the mother plant, preferably with 3 ~ 5 buds on it, and then insert it into the culture soil with a depth of about 4 ~ 6 cm. If the environment is not good enough, it can be covered with plastic film to keep warm and moisturize, and it will take root and sprout after a period of time.

Soak the seeds of plants in warm water overnight, then sow them on a suitable seedbed, then spread a thin layer of soil on the seeds, and then pour some water on them. Generally, it will germinate in about 20 ~ 30 days.

After black pine suffers from dead branch disease, it will cause the leaves of the plant to turn yellow, or even wither and die directly. After the disease is found, the diseased branches and leaves should be removed in time, and then thiophanate-methyl solution should be sprayed for control.

2. Pine aphid

After the black pine is invaded by pine aphid, it will suck the juice from the tender parts of the plant, and the overall growth will become worse.
