How to make preserved plum bonsai? Cultivation techniques of preserved plum bonsai

In winter, many flowers have withered, but only plum blossoms can blossom alone in the cold wind. Lamei is an ideal flower for flower appreciation in winter, which can be used not only for courtyard planting, but also for ancient pile bonsai, flower arrangement and plastic arts. Next, let's talk about the production methods and cultivation techniques of preserved plum bonsai.

Basin soil selection

Because the bonsai of Wintersweet is resistant to drought and waterlogging, whether it is new piles or shaped bonsai, pots with poor permeability such as porcelain should be avoided as far as possible. Should choose antique, good permeability of dark purple or ochre red, cyan black purple sand basin or tile soil basin, set off the golden flowers of wax plum, strong contrast, in order to enhance the ornamental effect.

Chimonanthus praecox is not strict on the soil substrate, but as a flowering bonsai, it is particularly important to select the soil substrate. If Chimonanthus chinensis grows in the basin soil with poor soil and poor permeability, it can not meet the needs of plant growth and development, let alone accumulate nutrients for flower bud differentiation, resulting in few or no flower buds of Chimonanthus praecox plants, resulting in rare or non-flowering of Chimonanthus praecox bonsai. Wax plum likes light, is not afraid of cold, likes warm, moist, loose, fertile and permeable sandy loam, or grows well and blossoms more in neutral fertile soil rich in humus. When selecting the bonsai substrate of Chimonanthus mume, the fertile sandy loam with loose and fertile and good permeability must be selected to lay a good foundation for the bonsai to blossom with many flowers, large flowers, colorful and strong fragrance.

Water and fertilizer management

Proper watering of Chimonanthus bonsai should be placed in a sunny dry place, and watering should grasp the principle of "dryness and re-watering". In the peak growing season of Chimonanthus praecox from April to May, according to the need of its growth potential, when the new shoot grows to 10cm, the intermittent water treatment should be carried out in time, and the flower bud should not be watered normally until the middle and late June. During this period, the branches and leaves that wilted the new shoots of the buckle plant can spray appropriate amount of water on the crown to prevent excessive water loss from causing damage to the plant. It is necessary to keep the soil moist and reduce the amount of water in autumn. Appropriate amount of water should be watered before and after flowering, too little watering leads to different florescence and poor ornamental effect. Watering too much is easy to drop buds and flowers, but also shorten the viewing period of Chimonanthus bonsai flowers, and fail to achieve the desired ornamental effect.

Reasonable fertilization and timely fertilization can not only promote the normal growth of bonsai branches and leaves, but also promote flower bud differentiation and more flowering. Generally, leaf spreading fertilizer was applied once in spring, and rotten liquid cake fertilizer was applied once in the middle and last ten days of May ~ June. High temperature in summer is the period of flower bud differentiation of Chimonanthus mume, and it is also the stage of vigorous growth of new roots of Chimonanthus mume. 0.25% potassium dihydrogen phosphate can be sprayed outside the root for about 5 times to promote flower bud differentiation, and then apply once rotten liquid cake fertilizer after autumn to accelerate the filling and rapid expansion of flower buds. The whole fertilizer based on phosphorus and potash fertilizer was applied once at the beginning of winter, and only scientific and reasonable fertilization according to the growth characteristics of Chimonanthus mume could meet the need of bonsai flowering. However, fertilization is not allowed during the flowering period, otherwise it will shorten the viewing period of wax plum blossoms.

Pruning and shaping

The pruning and shaping of Chimonanthus bonsai is mainly divided into three stages.

After flower shedding, before sprouting, combined with changing soil and basin, pruning, cutting off all kinds of branches that affect the tree shape, such as dead branches, disease and insect branches, overgrowing branches, overlapping branches, overdense branches, and so on, and for the annual branches to be retained, according to the needs of the shape of their respective parts, generally leave 1 ~ 3 pairs of buds for short pruning, so as to promote new shoots, symmetrical and plump trees, thick nodal branches and dense flower buds.

Because of the strong sprouting ability of Chimonanthus chinensis, in order to reduce the nutrient consumption and make the retained branches grow strong, it is necessary to cut off the useless branches such as sprouting shoots, over-dense branches and slender mediocre branches in time. When the branches grow 8 pairs of leaves, leave 6 ~ 8 pairs of leaves (10cm length) for tip cutting or coring, and usually grow secondary and tertiary shoots. Cutting with the same method can remove their apical growth potential, in order to promote the development of new branches and concentrate nutrients to promote flower bud differentiation.

In early winter, the flower bud on the branches of Chimonanthus mume has been expanded and colored, so it is necessary to cut off 2 ~ 3 shoots growing on all leaves and some branches in time, and for the accessory shoots with few or no buds, combined with the need of bonsai shape of Chimonanthus mume, cut off this part of branches, reduce over-dense branches and non-flowering branches, fully highlight its branches with less flowers and more flowers, and the ornamental effect is obvious.

Maintenance of preserved plum bonsai production

On the production and maintenance of Lamei bonsai, first of all, let's talk about the process of making Lamei bonsai.

I. material collection and cultivation measures (source of tree stump)

1. Artificial propagation. The propagation of Chimonanthus chinensis is generally based on grafting, and it can also be divided, sown, cut and striped. Grafting is mainly cut grafting, lean grafting and bud grafting can also be used. [sowing] the sowing time of preserved plum is collected in June, and it is best to sow along with picking. Soaking seeds before sowing for 24 hours to ensure early germination of seedlings. The seedlings sprouted in 10 days, the height of the seedlings was 10-20 cm, and the general seedlings did not blossom until 3-4 years. [crimping] after the root is stripped around in spring, it can also be pressed at high altitude in the rainy season (from late June to mid-July). [cutting] most of the grafting takes place from March to April, and the grafting is most likely to survive when the leaf buds sprout with the size of wheat grains. If the bud is too big, it is difficult to survive. One month before cutting, the sturdy and longer annual branches should be selected from the strong mother tree, and the top shoots should be cut off so that nutrients are concentrated in the middle of the branches, which is beneficial to the survival of grafting. The scion is about 6-7 cm long, and the rootstock can be used [dog fly Chimonanthus] or 4-5-year-old [Chimonanthus chinensis seedlings]. The cut of the rootstock can be slightly longer, reaching as deep as the xylem. The cut after binding should be coated with mud and then blocked up with soil. After that, about a month later, the sealed soil can be opened to check for survival. Chimonanthus chinensis, which is propagated by cutting method, grows vigorously and can be as high as 40cm to 60cm in that year.

Using red plum seedlings or ramet seedlings as rootstocks, the sunshine seedling net suggests cutting, leaning or budding, and the most frequently used is splicing. The cutting is carried out from the leaf buds in March to the big and small leaves of wheat grains, and the best grafting is between May and June at the turn of spring and summer, and the bud grafting is carried out from July to August. The cutting time is about the middle of March, and it is best to go when the leaf buds have just germinated to the size of the rice grain. If you miss the time, it is not easy to survive when the leaf buds are too big or have been sent out leaves. The seedlings of Prunus mume are usually used as rootstocks and precious varieties such as Suxin or Chukou Prunus as scions. The scion should select the sturdy and longer branches of the year in advance and cut off its top tip, so that nutrients can be concentrated on the buds in the middle of the branch. The scion is about 7-8 cm long, leaving 1-2 pairs of buds. Do not cut the scion too deep, whichever is slightly exposed xylem. The rootstock stake is cut from 5-6 cm above the ground, cut down from 1 cm of the diameter of the rootstock, split 4-5 cm, insert the scion into the incision of the rootstock, align it with the cambium, bind it firmly with soft hemp skin, and then seal the rootstock and the scion with loose soil until the top of the scion is covered. Keep the soil moist after that. A month later, loosen the seal to check whether it has survived, and if it has survived, wipe out other new buds on the rootstock to promote bud growth. Then cover the loose soil so that the fresh buds will not die by the wind and the sun. After another month, gradually remove the soil, let the buds gradually accept the sun. The preserved plum propagated by this method grows exuberantly and can grow to about 50 cm in that year.

The propagation is mostly carried out around May, and the rootstock is often used for several years [Chimonanthus praecox seedlings]. First, the rootstock seedlings are cultured in a pot to survive, move them to the vicinity of the mother branch used as a scion, select the branches on the mother branch that are the same thickness as the rootstock seedlings, and cut into a fusiform incision in the appropriate part, about 3-5 cm long, reaching to the xylem. The cutting should be flat, and the cutting length and size of the rootstock and scion should be the same, then lean them together so that the surrounding cambium is aligned with each other and tightly tied together with plastic tape from the bottom to the top. After the grafting survived, first cut the scion under the interface, and then cut off the branches and tips of the rootstock above the cut. The propagation of bud grafting should be from late May to late June. The hidden buds on the branches of the first year should be selected for bud grafting, and the survival rate is higher than that of the new buds on the branches of the same year, and the "x" grafting method can be adopted.

[ramets] ramet propagation is generally carried out when the leaf buds have not yet sprouted from February to March in spring. When dividing the plant, first dig up the soil on one side of the root of the mother plant, and cut off the daughter plant from the mother root with a sterilized knife to form a new plant. Then plant, after planting, pay attention to shade, keep the soil moist, wait until after the summer day, apply liquid fertilizer every half a month, the branches and leaves can grow vigorously in that year, and blossom after 2-3 years. Using this method to propagate, it is simple and easy, the survival rate is high, the seedling time is short, and the flower is quick.

2. Mountain mining: it is cultivated under the old root pile of wild Chimonanthus praecox in the mountain area to make the ancient pile of Chimonanthus mume, which is more common and has a quick effect. Select the old stump that has been cut down for many years, and prune the branches after digging back to protect the root system. Choose the place with moderate light, loose soil and good drainage to "raise the embryo", and then move it to the basin after survival. If it is an old pile of dog flies and plums, you can choose [plain heart Chimonanthus] for grafting and can be processed and modeled as needed after survival.

Type and style of bonsai

Wintersweet has many excellent characteristics suitable for making bonsai, and various types of bonsai can be made, such as: straight dry, oblique dry, lying dry, curved dry, withered, split dry, double dry, multi-dry, cliff, hanging branch, stone attached, co-planted, overhanging branch and so on. According to the size of the stump, it can be made into large, medium and small bonsai, as well as miniature bonsai (bonsai below 10cm). Wintersweet is also suitable to work with southern bamboo to make bonsai, yellow flowers and red fruits. The excavation of wild stakes.

Third, the process of potting.

1. Select the basin. Wax plum should use purple sand pottery basin, can also use glazed pottery basin. General seedlings Chimonanthus chinensis mostly use round basin, square basin, hexagonal basin, etc.; Wintersweet old pile can use medium-deep dregs basin or crabapple basin; cliff type often choose thousand-cylinder basin. Dark purple or ochre red is better in color to set off waxy yellow flowers and increase their ornamental effect. 2. Use soil. Chimonanthus praecox is not strict on soil, but it is better to use sandy loam with good drainage. Pots commonly used mature pastoral soil or rotten leaf soil mixed with 20% [rice chaff ash] as culture soil. 3. Planting. The transplanting of Chimonanthus praecox is mostly carried out in early spring, and it is suitable before and after the new bud germination of flower stem in the first ten days of March. It is generally appropriate to plant in an oblique way, which is easy to take advantage of when modeling. A plastic trim can be carried out before planting. Sufficient base fertilizer can be applied to the bottom of the basin when it is put on.

IV. Orthopedic techniques

The type of bonsai: wintersweet has many excellent characteristics suitable for making bonsai, and various types of bonsai can be made, such as: straight dry, oblique dry, lying dry, curved dry, withered, split dry, double dry, multi-dry, cliff, hanging branch, stone attached, co-planting, overhanging branch and so on. According to the size of the stump, it can be made into large, medium and small bonsai, as well as miniature bonsai (bonsai below 10cm). Wintersweet is also suitable to work with southern bamboo to make bonsai, yellow flowers and red fruits. The excavation of wild stakes. There are about four ways to shape the branches. (1) the upper branch type, also known as the deer horn type. The main branches and branchlets are mainly bent upward, growing from less to more, and the form is more natural, mainly by pruning and coring. (2) Transverse branch type, the main branch and branch grow nearly horizontally, the branchlet can be slightly upward, and it is formed comprehensively by flat binding, pruning and coring. (3) drooping branch type, the main branch is curved, the branches and twigs are all downward, and the branches are mainly formed by flat binding and knife cutting. (4) in the flat curve type, the main branches and branches are bent, and the branchlets can be bent and straight. There can be banding, folding and shaping, as well as pruning and heart-picking molding, giving people a sense of ancient wonder and beauty.

Shape:

1. The knife cuts and breaks the branches. According to the habit of brittle wound healing, easy to break and not easy to tie, the modeling design can be carried out in the growing period, but it is best when the bud just sprouts and does not spread the leaves. When the knife is cut off, it has an angle of 45 °with the longitudinal axis of the branch, and the depth can reach 2/3 of the diameter. Generally, according to the size of the broken branch angle, the small angle can be shallow, and the large angle can be deep, so that the branch can reach the desired shape without breaking it. After folding, it can be fixed with iron wire, the incision can be bandaged with plastic tape, and the incision can be removed only after the incision is healed. two。 Panza. During the growing period, you can use a knife to cut and break the branches, or you can tie them after the gram of water. Generally, after banding with iron wire, the requirements are met one by one. 3. Trim. Generally in the late flowering stage, combined with pruning modeling. Cut off the branches that are not compatible with the shaping of the main branch and cut them at an oblique angle of 45 °in front of the leaf axil of 0.5-1cm. Special attention should be paid to the bud direction of leaf axils. 4. Pick the heart. This is an important modeling method, there are generally 2 to 3 pairs of leaves, you can pick the heart, or a pair of leaves if necessary. The core can be removed 2 or 4 times a year to make the main branch rapid prototyping. 4. Processing. The styling and styling of Chimonanthus is mainly pruning and budding, supplemented by climbing. Xiyaojia Village, Yanling County, Henan Province is known as "Yiling Wax Plum Crown in the World". Its traditional plastic arts include "screen fan plum", "pimple plum", "hanging plum" and so on. In particular, Pingfan plum is the most popular, and its modeling process is as follows: during the period from March to April, the main branch should be twisted and spirally raised by "hob method" and "dragon knife method". When the bud is just sprouting, it will be cut obliquely at the place to be bent, and the knife edge is oblique, and the depth is up to 2x3 in the diameter of the branch. Bend carefully so that the upper part of the cracked xylem is supported on the lower section, use a pole to support the newly bent trunk, and tie it up with a rope. And then make all the top tips of the branches downward. The incision should be coated with mud within 1 month, and can not be removed, and should be filled up as it falls. After the formation of the basic skeleton, we should pay attention to pruning and pick the heart in time to maintain the shape of the screen fan. 5. Tree shape. Although Chimonanthus and Plum blossom do not belong to the same family, but their florescence is similar, and their flowers and aroma are also similar. Wax plum is fragrant and fragrant, and does not reduce red plum, so we can learn from the modeling principles of plum blossoms: "plum is beautiful with qu, straight is without appearance; plum is beautiful, regular without scenery; sparse is beautiful, dense is stateless"; "plum is rare but not expensive and complex; expensive old is not expensive and tender; expensive thin is not expensive fat; Guihe is not expensive to open" and so on. Therefore, the trunk should be oblique and horizontal, the branches and leaves should be sparse, and the pile is old and vigorous. In addition to the traditional modeling, in addition to the "screen fan type", "pimple type" and "hanging branch type", there are also "downwind type", "hanging branch type", "swimming dragon type" and so on. Now, the tree shape is mainly [oblique dry type] and [natural type].

IV. Maintenance and management

1. Place. Chimonanthus bonsai should be placed in a place to avoid the wind and the sun, avoid the cold wind, slightly shade in summer, potted plants in winter should be moved to indoor overwintering when the temperature is less than 1 ℃. 2. Watering. Chimonanthus is more resistant to drought and is known as "immortal Chimonanthus", but it should not be too dry. Usually the basin soil can be slightly drier, watering should be "dry and wet", if it is not watered, it will be watered thoroughly. Summer is the period of flower bud formation, which can not be short of water, so it should be watered once in the morning and evening. When the leaves fall in autumn, the pot soil can be drier and watered every 5-7 days. 3. Fertilization. Chimonanthus przewalskii is so fertile that cake fertilizer and water should be applied every 10 days in the early stage of flower bud formation from April to June. From the end of June to before ambush, the thin fertilizer and water with the combination of nitrogen and phosphorus was applied once a week to promote the formation of flower buds. The fertilizer should be thin when topdressing for 1 or 2 times in summer. Apply it again after autumn. When changing the basin, you can apply sufficient basic fertilizer such as bone meal and bean cake at the bottom of the basin. 4. Pruning. Pruning and sprouting are very important to make Wintersweet blossom year after year. [pruning is usually between March and June] and stops after August. The old flower branches should be truncated immediately after flowering each year, leaving a maximum length of only 15cm to 20cm. After the new branch grows 2-3 pairs of buds, the terminal bud is removed, and soon the side branch grows again. After growing to 10 cm, the bud is picked again and repeatedly several times until the flower bud is basically formed. It is also necessary to prune all kinds of cross branches, parallel branches, overlapping branches, opposite branches, long branches, and overdense and thin branches that affect the appearance of the tree. It is said that there is no shortage of branches in the flower proverb, so the wax plum can be re-cut. 5. Turn the basin. The bonsai of Chimonanthus mume should be turned over every 1-2 years, and it is better to turn the pot at the end of winter and the beginning of spring. The germinated buds can be removed before turning the basin, and then transplanted when the hidden buds sprout and expand after about 5 days. When turning the basin, get rid of the old soil, cut off the rotten and withered roots, and trim the overlong old roots. Instead of frozen crisp pond soil or humus-rich rotten leaf soil, mixed with appropriate amount of rice chaff ash and sandy soil. 6. Prevention and cure. Wintersweet bonsai is usually placed in a ventilated and transparent place, resulting in fewer diseases and insect pests. Branch blight and leaf spot disease may occur due to over-dense placement, weak light and poor ventilation, which can be controlled by spraying 500 times of carbendazim and Dysen zinc wettable powder. Individual plants will have a small amount of red spiders, shell insects, whitefly and other insect pests, generally with scale and other acaricidal agents to control. Wax plum has strong resistance to diseases and insect pests, and occasionally has pests such as diamondback moth, large coir moth, aphids, shell insects and so on, which can be controlled by [1500 dichlorvos solution] or [crystal trichlorfon] and [1000-1500 times liquid spraying]. 7. The flower buds of potash plum bonsai with additional application of phosphorus and potassium fertilizer are mostly pregnant on the spring shoots and twigs born in the same year. Generally, the new shoots are lignified and later enter the stage of human flower bud differentiation in June every year. The flower bud differentiation ends and develops completely from July to September, and the summer and autumn shoots cannot form flower buds. Therefore, it is appropriate to apply potassium dihydrogen phosphate or boric acid every half a month in summer. Foliar spraying or pot soil application can greatly increase the bud pregnancy rate and accelerate the growth and development of flower buds of potted Wintersweet. 8. Daily maintenance of Chimonanthus praecox bonsai before sprouting combined with changing pot soil, shaping and pruning, cutting off dead (root) branches, disease and insect branches, overdense (root) branches and other branches that affect the tree shape. And for all the annual branches to be left, 1 to 3 pairs of buds are generally left for short cutting according to the morphological needs of their respective parts. only in this way can the new shoots grow normally, the tree shape is plump, the branches are thick, and the flower buds are dense. to lay a good foundation for the late bonsai of Chimonanthus praecox with more pregnant buds and dense flowering.

The making of Prunus mume Bonsai the maintenance method of Lamei Bonsai

All kinds of bonsai will appear in different places, radish and green vegetables have their own preferences. Today our theme is preserved plum bonsai, wax plum blossoms in winter, a very beautiful flower, do you want to keep it? When you see it, do you think it is very beautiful? this is when it just bloomed. It was opened after the test of severe winter. In such cold weather as winter, it can still open so beautifully. Let's take a look at how to raise the preserved plum bonsai.

Introduction of preserved plum bonsai

Chimonanthus is a traditional bonsai plant in China, with graceful trees, quaint roots, bright and brilliant flowers on the sloping branches, and its fragrance is intoxicating, especially warm in the cold winter. Chimonanthus chinensis is a deciduous shrub of Chimonaceae and Chimonanthus. It has many varieties, such as pure yellow, golden yellow, light yellow, ink yellow, yellow white, light white, silver white, etc., and the stamens are red, purple, reddish brown, pure white and so on. The more famous varieties are traditional varieties such as vegetarian Chimonanthus, sandalwood Chimonanthus, Chimonanthus hukou, Chimonanthus giganteum, as well as famous varieties such as Queen Chimonanthus, Tiger hoof Red Chimonanthus, Jinpanyu Chimonanthus, Yinzhong Chimonanthus, Bailianwenmei and Jianhongwenmei.

In the "hometown of Chimonanthus", Henan Province, the traditional bonsai forms of Chimonanthus include single plum, dragon plum, pimple plum, single hanging plum, double hanging plum, round hanging plum, Pingfan plum, pearl rolling curtain and so on. It can not only be modeled with young trees, but also use old and simple ancient piles of Chimonanthus praecox as rootstock, grafting fine varieties such as Chimonanthus praecox, Chimonanthus untold, whose roots are dilated and in the shape of a pimple, which is called "pimple plum".

As the branches of Chimonanthus are brittle and easy to break, it is not suitable for large-scale bending modeling, generally only brown silk will be used to slightly hang the trunk or branches, and then trim the twigs slightly, generally from May to August, this is because the branches are soft at this time, and attention should be paid to watering before operation to further soften the branches and facilitate modeling operation.

Second, the production of preserved plum bonsai

The first step, material selection and cultivation

The old root pile of wild Chimonanthus praecox in mountainous area is cultivated in the ground, and the ancient pile of Chimonanthus praecox is made, which is more common and has a quick effect. The method is to select the old stump that has been cut down for many years, and after digging it back, pay attention to protecting the root system and pruning the branches. Choose the place with moderate light, loose soil and good drainage to "raise the embryo", and then move it to the basin after survival. If it is an old pile of dog flies and plums, it can be grafted with plain heart wintersweet, and it can be processed and modeled as needed after survival.

The second step, the process of potting.

Wax plum should use purple sand pottery basin, can also use glazed pottery basin. General seedlings Chimonanthus chinensis mostly use round basin, square basin, hexagonal basin and so on. Wintersweet old pile can use medium-deep dregs basin or crabapple basin, cliff type more choose thousand-cylinder basin. Dark purple or ochre red is better in color to set off waxy yellow flowers and increase their ornamental effect. Chimonanthus praecox is not strict on soil, but it is better to use sandy loam with good drainage. The commonly used mature pastoral soil or rotten leaf soil mixed with 20% bran ash was used as culture soil. The transplanting of Chimonanthus praecox is mostly carried out in early spring, and it is suitable before and after the new bud germination of flower stem in the first ten days of March. It is generally appropriate to plant in an oblique way, which is easy to take advantage of when modeling. A plastic trim can be carried out before planting. Sufficient base fertilizer can be applied to the bottom of the basin when it is put on.

The third step, pose modeling

Although Chimonanthus and Plum blossom do not belong to the same family, but their florescence is similar, and their flowers and aroma are also similar. Wax plum is fragrant and fragrant, and does not reduce red plum, so we can learn from the modeling principles of plum blossoms: "plum is beautiful with qu, straight is without appearance; plum is beautiful with sparse, regular without scenery; sparse is beautiful, secret is stateless", "plum is rare but not expensive and complex; expensive old is not expensive and tender; expensive thin is not expensive fat; Guihe is not expensive to open" and so on. Therefore, the trunk should be oblique and horizontal, the branches and leaves should be sparse, and the pile is old and vigorous. In addition to the "screen fan type", "pimple type" and "hanging branch type" of Yiling, Henan Province, there are also "downwind type", "hanging branch type", "swimming dragon type" and so on.

Third, the maintenance methods of preserved plum bonsai

Place: Chimonanthus bonsai should be placed in a place to avoid the wind and the sun, avoid cold wind, slightly shade in summer, pot plants in winter should be moved to indoor overwintering when the temperature is less than 1 ℃.

Watering: wax plum is more drought-tolerant, it is known as "immortal wax plum", but it can not be too dry. Usually the basin soil can be slightly drier, watering should be "dry and wet", if it is not watered, it will be watered thoroughly. Summer is the flower bud formation period, can not be short of water, should be watered in the morning and evening, after autumn leaves, the basin soil can be dry, watering every 5-7 days.

Fertilization: wax plum is very fertile, so it is appropriate to apply cake fertilizer and water every 10 days in the early stage of flower bud formation from April to June. From the end of June to before ambush, the thin fertilizer and water with the combination of nitrogen and phosphorus was applied once a week to promote the formation of flower buds. The fertilizer should be thin when topdressing for 1 or 2 times in summer. Apply it again after autumn. When changing the basin, you can apply sufficient basic fertilizer such as bone meal and bean cake at the bottom of the basin.

Pruning: pruning and sprouting are very important to make Wintersweet blossom year after year. Pruning usually takes place from March to June and stops after August. The old flower branches should be truncated immediately after flowering each year, leaving a maximum length of only 15cm to 20cm. After the new branch grows 2-3 pairs of buds, the terminal bud is removed, and soon the side branch grows again. After growing to 10 cm, the bud is picked again and repeatedly several times until the flower bud is basically formed. It is also necessary to prune all kinds of cross branches, parallel branches, overlapping branches, opposite branches, long branches, and overdense and thin branches that affect the appearance of the tree. It is said that there is no shortage of branches in the flower proverb, so the wax plum can be re-cut.

Pest control: wax plum has strong resistance to diseases and insect pests, and occasionally has pests such as diamondback moth, big coir moth, aphids, shell insects, etc., which can be sprayed with 1500 times of dichlorvos or 1500 times of crystal trichlorfon.

Finally, I would like to tell you that the old mountain wild Chimonanthus root pile is cultivated under the ground to make the ancient Wintersweet pile, which is more common and has a quick effect.
