Is black pine easy to care for?

Question 1: How to maintain bonsai black pine. First of all, black pine likes an environment with sufficient sunshine and air circulation, and is resistant to cold and drought. Black pine is resistant to barrenness and does not like heavy fertilizers. Autumn is the season when pine buds grow and branches thicken. You can apply decomposed thin cake fertilizer several times to make it grow robustly. The germination power of black pine is not that strong, so it should not be pruned too much. The needles of black pine are longer. In order to shorten them, in addition to controlling water and fertilizer when new leaves grow in spring, the Japanese bonsai community also created the short-leaf method, which includes cutting young branches, thinning buds, and picking old leaves. Specifically, The operation is as follows: from July to August, cut off all the new branches that grew in the current year. Since plants have the ability to self-recover from injuries and find balance, new shoots will grow on the branches from August to September. They can be From September to October, thin out excess buds, leaving only two buds on both sides of the branches or in the horizontal direction. Later, as the climate gradually cooled, the growth of new buds and leaves was inhibited. The remaining old leaves were cut off from November to December, so that the plant was left with the second round of short needles. At this time, it was a black pine bonsai. The best viewing period.

In winter, move it to a cold room to overwinter, just keep the soil from freezing. If the temperature is too high, it will be detrimental to the growth of the second year. You can also bury the pot outdoors in a sheltered and sunny place to overwinter. Repot the plant before germination every 2 to 3 years. When repotting, remove 1/3 to 1/2 of the original soil and add some new soil. The pot soil must be loose, breathable, and have good drainage.

Question 2: How to grow potted black pine. Pine trees are especially sensitive to excess water, so one day when we want to do work on black pine, we must constantly touch its branches and leaves during the work. Please be careful when doing this because if there is too much water in its body at this time, you will see it begin to drop leaves continuously after the work is completed. Therefore, it is often necessary to drain the water for several days before moving the pine tree to allow its body to The excess water evaporates.

The so-called watering is to reduce the water accumulated in the tree. This method is very simple, which is to control and reduce the amount of watering.

Wildland The leaves of black pine are quite long, which seems to have some flaws in imitating the microcosm of nature. In order to shorten the length of black pine leaves, people in the Japanese bonsai industry experimented and introduced the short-leaf method of black pine. However, in various types of black pine in China, There is no detailed explanation of it in reference books. Moreover, due to the differences in climate and environment between the two countries, this method is used in Taiwan, our country, and cannot be accepted in full. Here we use our own narrative method. Let me explain to you in detail!

Characteristics of black pine:

This unit is represented by black pine. The growth characteristics and control methods of other tree species in the same family of Pinaceae are similar.

Black pine is an evergreen coniferous tree. If the overall leaf area of ​​pine and cypress plants, both of which are evergreen conifers, is suddenly reduced by half, the growth of the tree will immediately shrink and stop. , severe cases may even lead to the risk of death, and on any single branch of a coniferous tree, if there are no leaves at all, the survival rate of the branch will be very slim, and it can almost be regarded as dead. This is to deal with a large number of coniferous trees. The important thing to pay attention to when planting plants is that no matter we want to make any changes to it, remember that it is safe to maintain its leaf area at more than 60% of the original size. Pine and cypress cannot be removed like weeds, they can only be thinned out. Leaves to control their growth

(Defoliation in bonsai terminology refers to removing all the leaves on the branches. However, among specific coniferous tree species, defoliation will cause partial or comprehensive defoliation of the coniferous trees. Therefore, in coniferous trees, their physiology can only be controlled by leaf thinning. Leaf thinning means reducing the number of leaves to a certain proportion of the original, and the proportion is preferably greater than 60% of the original)

For example As shown on the right side of Figure 1, two needle-like green sticks are considered a leaf of black pine. The leaves grow in whorls along the periphery of the branch. At the junction where the branch intersects with the bottom of the two needle sticks, There is a growth point of a leaf bud. The growth point of a leaf bud must mature before it has the ability to breed and reproduce new branches and leaves. Nature has decreed that this growth point will not mature until one year after the leaves appear. Moreover, this leaf bud point When the leaves are manually pulled out, they will fall off or be damaged. Therefore, retaining an appropriate amount of old leaves and retaining more mature leaf buds is also a technique used to prevent accidents and preserve the vitality of the tree.

Spring buds and autumn buds:

Spring buds: (called Chunhong in Taiwanese in the industry)

In the wild, when black pine branches and leaves grow normally, At the center of the black pine leaf cluster, you can see the brown leaf stamens as shown in the second picture on the right. Normally, it is responsible for absorbing and accumulating nutrients, and nurturing the young pine leaves hidden in its leaf stamens waiting to grow. Gradually become longer and thicker. When the growing season comes, the young pine leaves in the stamens will start to penetrate the stamens from the bottom and grow outward, and the stamens will also quickly grow upward at the same time. Most of the time, there is only one single stamen at the center point of each branch. If it appears to be bifurcated, it means that it will develop additional new branches, and this form of stamens The growth is most obvious and rapid in spring every year, so the leaf stamens are called spring buds. The growth form of this kind of spring buds is the mainstream growth mode of black pine in nature

Black pine After the growth of a leaf bud is completed, under normal circumstances it does not have any special function. Only when its main spring bud growth pattern is destroyed by external forces and stops, the leaf bud will receive the sudden nowhere transmission. It is activated by nutrients, and then new leaves grow from the leaf bud points. Since it inherits the growth of spring buds, its growth is also different from the growth method of spring buds, so we call it secondary buds (autumn buds). buds), the secondary buds will first grow into clusters of needle-shaped fetal leaves as shown in Figure 3. The fetal leaves protect the young pine leaves gestating inside them. After the young leaves are incubated and the fetal leaves open, the young leaves will It just started to grow from between the fetal leaves. At the beginning, there were no brown stamens like spring buds in the center of the leaf cluster.

After seasonal growth and cultivation, the brown leaf stamens like spring buds will slowly grow from the center of the pine leaf cluster. At the same time, the life form will gradually transform into spring bud-like growth. The above-mentioned replacement is mainly in spring. The secondary growth mode in which buds grow and burst out, we call it...>>

Question 3: Can black pine be grown at home? Yes, as long as your indoor area is large

After inhibited growth, the shape is curved, majestic and majestic. Both have great ornamental value. Black pine bonsai has strong adaptability to the environment and can be cultivated in courtyards and balconies.

In foreign countries, there are also high hedges that are densely planted in rows and neatly trimmed, surrounding the outside of buildings or residences, which not only beautifies but also protects them.

Question 5: Planting and maintenance of black pine? Cultivation techniques:

First, when digging, expand the mining surface and pay attention to bringing as much soil as possible. Because black pine grows in hillside gravel soil, there is less soil, and the weather is dry in winter, the soil contains less water and has poor viscosity, so the soil at the roots should be protected as much as possible when digging. Because the root soil is rich in root fungi, which are black pine fungi, they are extremely conducive to root growth. After excavation, simple wrapping with plastic bags should be done promptly to prevent soil loss during transportation and facilitate transplantation.

Second, when digging, pay attention to protecting the root system of the black pine. You should start digging a little further away from the pine tree. First, hollow out the surrounding soil, retain as much of the main root as possible, and cut off the root incisions. It should be smoothed, the rotten roots should be cut off, and the root system should be avoided as much as possible. Especially the lateral roots and fibrous roots of black pine rooted in sand and gravel have weak root systems. They should be kept as long as possible and should be protected during excavation.

Third, the excavated black pine must be put into the soil in time. The sooner, the better. Over time, the roots will lose water and dry up, affecting their survival. In order to prevent the roots from being buried too deep, you can plant them high or shallow, and then cover them with soil. If you cannot cultivate them in the ground, they should be potted in time.

Fourth, the upper pot of black pine is very important. Before planting, the bottom of the pot should be lined with gravel and tiles to facilitate ventilation and drainage, and then the surroundings should be filled with soil. If the gaps in the soil are too large, it is easy to cause frozen roots. Cover the pot with a straw curtain to prevent freezing.

Fifth, the original soil on the mountain is the best soil, or a mixed soil made of coarse yellow sand, coal ash, and yellow mud can be used, with a ratio of 0.5:0.25:0.25.

Sixth, pruning must be carried out in time after potting. Too many branches and leaves will affect the root system's insufficient water supply and consume a lot of water and nutrients.

Question 6: How to maintain this kind of bonsai? Black pine 15 points (1) Maintenance and management Placement: Black pine is suitable for growing in a sunny, humid and ventilated environment, but small bonsai should not be exposed to strong light when the temperature is high in midsummer. It can be placed outdoors in winter. It is best to bury the pot in a sunny and leeward ground with only the branches exposed above the soil. If it is placed indoors for the winter, the indoor temperature should not be too high, and it must be left before the Qingming Festival. Watering: Black pine likes dryness. Do not water too much. It should be completely dry before watering. However, spraying water on the leaves frequently is beneficial to growth. Proper watering in spring and summer can make new branches low and needles short. Fertilization: Black pine does not like fertilizer. It can be applied with thin decomposed cake fertilizer and water twice every spring during the peak growth period, and fermented cake crumbs can be applied again in autumn. Pruning: Pruning of black pine is mainly done by picking buds. It is carried out between March and April every year when the new buds are elongating but the needles have not yet emerged. Generally, about 1B2 of each terminal bud is removed. If the bonsai does not need to grow branches, all the terminal buds can be removed. In addition, branches and leaves that affect the appearance of the tree can be pruned during the winter dormancy period. Repotting: Repotting of black pine can be done every 3 to 5 years, preferably between February and March, but also after autumn. When repotting, remove about 1B2 of old soil, cut off dead and rotten roots, and shorten some long roots. It is best to prune the branches and leaves at the same time. Pest and disease control: The main diseases of black pine include leaf rust, needle disease, branch disease and pine burr disease. Common pests include aphids, scale insects, red spider mites, and pine borers. Pine needle rust and pine tuber disease can be prevented and controlled by spraying 300 times of 65% wettable ferric thiram or zinc thiram; needle drop disease can be prevented by spraying Baume 0.5 degree lime sulfur mixture. Pests such as pine stem borer and red spider mites can be controlled by spraying 50% borer-killing EC 1000-1500 times or 40% dimethoate EC 2000 times. (2) Appreciation: The branches of black pine are spread horizontally, the crown is like an umbrella canopy, the needles are dark green all year round, and the winter buds are silvery white. They can be displayed and viewed all year round. Black pine is a positive tree and requires sufficient light. During the growth period, especially during the budding and leafing stage, it cannot be left indoors for long periods of time for viewing. The black pine bonsai that has been cultivated for many years has a strange appearance like a dragon, a pan, and a phoenix. The old stems are vigorous and the roots are twisted, showing perseverance and vitality. The pines in the forest are hundreds of feet long, and their scales are gray with age. This is a poem by Su Dongpo, a writer in the Song Dynasty, praising the posture of pine trees.

Question 7: Is it good to raise black pine at home in Feng Shui? People from the Northeast generally raise longevity pine, golden pine, and podocarpus in Feng Shui. There seems to be no mention of black pine!

The above three pines can be placed according to the Xuanwu position, which can bring wealth and prosperity.

Some plants have strong Yin energy, such as vines and ferns, and it is best not to plant them at home.

Question 8: How should black pine bonsai be maintained? Are they strict about lighting in Zhejiang? 5 points: Black pine bonsai has strong adaptability to the environment and can be cultivated in courtyards and balconies. Its branches spread horizontally, its crown is like an umbrella canopy, its needles are dark green, it is evergreen all year round, and its quaint appearance can be enjoyed all year round. During the growth period, it should be placed outdoors in a place with sufficient sunlight and air flow. It should not be placed indoors for a long time. The pine tree stump scene that has been cultivated for many years, with its vigorous and twisted trunks and intertwined roots, expresses the dragon cricket's strange appearance and perseverance in vitality. It is a good product for family cultivation and appreciation. The pine branches spread horizontally, the crown is like an umbrella cover, the needles are dark green all year round, and the winter buds are silvery white. They can be displayed and viewed all year round. Black pine is a positive tree and requires sufficient light. During the growth period, especially during the budding and leafing stage, it cannot be left indoors for long periods of time for viewing. The black pine bonsai that has been cultivated for many years has a strange appearance like a dragon, a pan, and a phoenix. The old stems are vigorous and the roots are twisted, showing perseverance and vitality. "The pines in the forest are hundreds of feet long, and their scales are wrinkled with age." This is a poem by Su Dongpo, a writer in the Song Dynasty, praising the posture of pine trees.

In order to meet the needs of making bonsai, when cultivating in the open field, you should choose a place with sufficient light and relatively poor soil, control the supply of water and nutrients, and make the main root thick and short, the lateral roots developed, and the stem short and buckling. , the branches and leaves are dense and clustered, the posture is simple and elegant, and it can be potted and processed when it is good. The main trunk of the stump is relatively thick and can be appropriately cut and processed, and then the remaining side branches can be climbed into a straight or drooping shape. When selecting side branches, care should be taken to avoid leaving parallel branches or symmetrical branches. It is better to have a layered branch. The reshaping process of black pine should be carried out during the dormant period, when the sap flows slowly, and the branches will be pruned without risk of rosin leakage. During the growth period, you can only climb it to shape it, or pick buds to control the growth, but you cannot prune it for shape.

Black pine likes an environment with plenty of sunshine and air circulation, and is resistant to cold and drought. It can be placed on the terrace, balcony or platform in the courtyard all year round, where there is sufficient light and air flow.

However, small bonsai should not be exposed to strong light in midsummer. In winter, it can be overwintered in the open. It is best to bury it in a pot in a sunny and leeward place. If you overwinter indoors, the room temperature should not be too high, and you can move it outdoors during Qingming Festival. There is a flower proverb that says "dry pines and wet cypresses", so it is advisable to keep the pot soil dry, do not water it when it is dry, and water it thoroughly to avoid water accumulation. Especially in spring, when the leaves sprout and grow, the water should not be too large to prevent branches and branches from growing. The leaves grow long. In summer and early autumn, the temperature is high and the air is dry. You should keep the soil moist and avoid pouring water that is "wet on top and dry on the bottom". You can also spray water on the leaves in the morning and evening to increase the air humidity and make the leaves beautiful. Pay attention to drainage and waterlogging to avoid root rot due to water accumulation in the pot soil. Black pine small bonsai should not be exposed to strong light during high temperatures in midsummer. It can be placed outdoors in winter. It is best to bury the pot in a sunny and leeward ground with only the branches exposed above the soil. If it is placed indoors for the winter, the indoor temperature should not be too high and it must be left before the Qingming Festival.

The germination power of black pine is not that strong, so it should not be pruned too much. However, in order to maintain the graceful shape of the tree, buds can be picked from March to April every year. The method is that when the buds of black pine gradually When the buds swell and turn green and are about to sprout leaves, remove one-half to one-third or even more of the buds. The buds must be picked comprehensively. Strong buds should be picked first, followed by weak buds, in order to balance the tree's potential and make the branches and leaves more balanced. Or a neat crown.

Question 9: How to grow black pine bonsai? First of all, lodgepole pine likes an environment with plenty of sunshine and air circulation, and is resistant to cold and drought. Black pine is resistant to barrenness and does not like heavy fertilizers. Autumn is the season when pine buds grow and branches thicken. You can apply decomposed thin cake fertilizer several times to make it grow robustly. The germination power of black pine is not that strong, so it should not be pruned too much.

From September to October, thin out excess buds, leaving only two buds on both sides of the branches or in the horizontal direction. Later, as the climate gradually cooled, the growth of new buds and leaves was inhibited. The remaining old leaves were cut off from November to December, so that the plant was left with the second round of short needles. At this time, it was a black pine bonsai. The best viewing period.

In winter, move it to a cold room to overwinter, just keep the soil from freezing. If the temperature is too high, it will be detrimental to the growth of the second year. You can also bury the pot outdoors in a sheltered and sunny place to overwinter. Repot the pot once every 2 to 3 years before germination in spring. When repotting, remove 1/3 to 1/2 of the original soil and add some new soil. The pot soil must be loose, breathable, and have good drainage

< p> Question 10: Is it good to raise black pine at home in Feng Shui? In fact, Northeastern people don’t say much about what kind of support they have. That kind of turtle is very simple and has few things. Silver Arowana, many people call it Feng Shui fish, in fact, what I see is superstition, Silver Arowana is difficult to raise, more things, but good-looking, and at the same time improves the fun of raising turtles more than Silver Dragon.
