What should we pay attention to when maintaining and styling black pine? What are the processes? Are there any detailed steps?

Black pine is a traditional tree species used for making bonsai. Not only is it powerful, upright and full of masculinity, it has always been called the "man's pine". Black pine is an evergreen tree of the Pinaceae family. Different growth environments make the growth of black pine very different. In places with suitable environment and fertile soil, black pine can reach a height of tens of meters. But when it grows in places with harsh environment and poor soil, it is no taller than a foot. I would like to share with you some tips on the propagation, maintenance, pruning and pruning of black pine.

Planting

There are many black pine propagation bases now, and they generally use the seed sowing method. The only limitation of this method is that it takes too long, but it has many benefits. , still needs to be promoted. Another method is to process black pine from green seedlings. Choose stakes for bonsai that have thicker branches and branches at the bottom. They have been cultivated through stem cutting.

Excavate before the budding period in early spring. If conditions permit, keep the original soil of the tree roots, wrap them with wrappers, and apply mud to moisturize them. Before transportation, make a short cut of the roots, trunks, and branches, and cut off all the branches that do not need to be retained. It should be noted here that needles must be left on the retained branches, otherwise, there is a high probability that they will die later. Apply a healing agent to the wound to prevent sap loss and wound infection.

Before planting, conduct careful pruning to reduce the scope of the crown and rhizomes as much as possible to facilitate potting later. When curing, it is best to choose a sunny and well-ventilated place for curing. After about 2 years of growth and maintenance, it will basically be ready for shape. I believe that after these two years of curing and maintenance, the styling concept must have been quite mature.

Shaping

The newly sprouted branches of the black pine are soft, which is a good time for pruning. According to the idea, bonsais can be made into different styles such as curved stems, waterfronts, and stone-attached bonsais. . If it is an old black pine stump, it must be made according to the shape of the tree stump. You cannot forcefully destroy the shape of the tree stump on a large scale to achieve your own creative effect. In the end, it will only end up being a piece of cake.

The correct method is to take advantage of the situation, adapt the material to the shape, and use a combination of pruning and pruning. Naturally, you can create a naturally beautiful, vigorous and simple black pine bonsai. No matter what form of black pine bonsai we make, we cannot violate the growth laws of nature. Only by observing the natural growth form of black pine can we create a bonsai of higher value.

The modeling time of black pine bonsai is from January to March. During this period, the sap of black pine flows slowly. When treating the wounds on the branches, there is basically no sap flowing out, which will not have any major impact on future growth. Influence. However, it should be noted that the germination ability of black pine is weak, so be careful when pruning and keep branches as much as possible. However, the black pine has a well-developed root system and can be made into a very popular root-lifting shape, adding to its ancient charm.

Environment

The growth characteristics of black pine are that it likes a sunny and well-ventilated environment, and is cold-resistant and drought-resistant. It is suitable for outdoor maintenance, choose an environment with sufficient light and good ventilation, keep the pot soil dry, water it until it is dry or water it thoroughly, and do not give too much water. One is to prevent water accumulation, and the other is water. It is easy to cause branches and leaves to grow excessively.

In summer and autumn, attention should be paid to watering. At this time, the temperature is higher and the weather is dry. Watering must be thorough, keep the pot soil moist properly, and do not water half. Spray water in the morning and evening to maintain the humidity of the environment. Special attention should be paid to drainage and waterlogging prevention during the rainy season to avoid water accumulation and hardening in the pot soil.

Black pine leaves are relatively resistant to barrenness and do not like fertilizer too much. During the growth period, you do not need to apply too much fertilizer. You only need to apply some organic cake fertilizer to help the growth. Applying too much fertilizer will cause the branches and leaves to grow. If the growth is too vigorous, it will affect the beauty of the shape and may cause fertilizer damage. Try to use as little fertilizer as possible. During the growth period in autumn, you can apply some organic cake fertilizer to help supply nutrients and make it grow stronger, so as to achieve the growth of pine buds and thickening of branches.

In winter, just ensure that the pot soil does not freeze. If the temperature is too high, it will affect its growth in the second year. It is best to bury the pot together in a sunny and sheltered place to overwinter. Repot and replace the soil every 2-3 years, retaining half of the original soil to protect the root system from damage and resume growth as soon as possible.

Pruning

The germination of black pine is not strong, so it is not advisable to prune too much. Black pine can be bud-picked between March and April every year. When the buds turn green and swell and are about to sprout leaves, remove half or more of the buds and remove all the spores to ensure a balanced tree vigor and a neat crown.

The needles of black pine are longer, but to shorten them, in addition to good water and fertilizer management when new leaves sprout, you also need to use methods such as cutting young branches, thinning buds, and removing old leaves. . Between July and August every year, cut off all the new branches of the current year and wait for new buds to sprout. They will sprout around August to September. Then remove the excess buds, leaving only the sides or horizontal sides of the branches. direction of the two buds. As the temperature gradually drops, the growth of new shoots and leaves can be inhibited. In November, the remaining old leaves can be cut off, so that only the new short leaves in September are left. It is also the best viewing period for black pine bonsai.

Pests and diseases

Prevention of diseases and insect pests of black pine is the key. The key is to be strong yourself so that you will be less likely to get sick. Only when the tree is weak will the occurrence of pests and diseases occur.

Branch blight, which causes branches and leaves to wither and turn yellow, is caused by climate abnormalities. Drought, floods, strong winds, high temperatures and humidity, frost damage, etc., or growth weakness caused by malnutrition and other reasons will cause the occurrence of pests and diseases.

When pests and diseases occur, one is to spray pesticides in time to treat them, and the other is to increase fertilizers. Organic fertilizers can be applied in holes to provide nutrients and help restore the tree's vigor. Only when the tree grows strong can we stay away from the harm of pests and diseases. In the season of high incidence of pests and diseases, spraying pesticides can be effective.
