When watering the black pine, we must follow the principle of dry and thorough watering. Black pine doesn't like too wet soil, so it usually waits until the soil is dry before watering. Although spring and summer are the peak season for the growth of Pinus thunbergii, it is necessary to reduce the amount of watering appropriately to avoid growing too high.

2. Proper lighting

When breeding black pine, keep enough light. If the light is insufficient, the branches and leaves will grow in vain, and the shape of the whole black pine bonsai will become unsightly. Except the strong light in summer, all sunshine can be accepted in other seasons, so that the black pine bonsai will grow better.

The suitable temperature for the growth of Pinus thunbergii is about 65438 02 ~ 28℃. When the temperature is too high in summer, the black pine bonsai should be moved to a cool and ventilated place to escape the heat. The temperature in winter can't be below zero, so it is better to move indoors for the winter.

4. Rational fertilization

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. Fertilizers are mainly nitrogen, phosphorus and potassium fertilizer.

5, timely pruning

Pruning is very important in the maintenance method of black pine bonsai. Every winter, the bonsai of black pine can be pruned again, the shape of the bonsai can be adjusted appropriately, all the weak branches can be cut off, and buds can be picked once in March-April in spring, which is more conducive to the growth of plants. Usually branches that are too dense and too long will be cut off, which will affect the shape of bonsai.

Second, the propagation method of Pinus thunbergii 1, cutting propagation

Cutting propagation of black pine is very difficult. Generally, the cutting method is adopted. 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.

3, sowing and breeding

At present, the method of sowing is generally used to breed black pine in a large area. 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.

Three, common pest control 1, black pine dead branch disease

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. After the pests are found, they need to be killed manually in time, but this is generally a temporary solution, and Bordeaux mixture needs to be sprayed for prevention and control.
