Hibiscus Hibiscus, also known as Zhu Jin, is a strong positive plant, which likes warm and humid, needs plenty of sunshine, and is intolerant of shade, cold and drought. Only potted plants can be planted in the Yangtze River valley and northern China, and they can overwinter in greenhouses or other protected areas at 12℃- 15℃. When the room temperature is lower than 5℃, the leaves turn yellow and fall off, and when it is lower than 0℃, they are frozen. Pruning resistance and strong branching ability. It has a wide adaptability to soil, but the slightly acidic loam with rich organic matter and pH 6.5-7 grows best.
Breeding mode
Cutting propagation method
In May -65438+ 10, the greenhouse overwinters, but the survival rate is high in rainy season. The annual semi-lignified cuttings are the best, the length is 10 cm, the lower leaves are cut off and the upper leaves are left, the incision should be flat, the cuttings should be inserted in the sand bed, and the air humidity should be high. Room temperature 18-2 1℃, cuttings take root after 20-25 days. Treating the cutting base 1-2 seconds with 0.3%-0.4% indolebutyric acid can shorten the rooting period. When the roots grow to 3-4 cm, transplant them into a pot.
transplant
In spring and autumn. It is mostly used for hibiscus varieties with difficult cutting or slow rooting, especially for double-petal varieties with low cutting survival rate. Branch grafting or bud grafting can be used, and single-petal hibiscus flower is used as the rootstock. Grafted seedlings bloom in the same year.
cultivation techniques
Changing pots and pruning
The soil for potted plants should be loose and fertile sandy loam, and the pots should be changed before moving in early spring and April every year.
There are three things to do when changing pots: first, put in new culture soil; The second is to cut off some fibrous roots that are too dense and curly; The third is to apply plantar fertilizer and slightly add phosphate fertilizer to the pelvic floor. In order to maintain a beautiful tree shape and a large number of flowers, according to the characteristics of strong germination ability of hibiscus, pruning and shaping can be carried out before and after leaving the house in early spring. Except for 2-3 buds at the base, all the upper branches were cut off. Pruning can promote the new branches to grow more vigorously and the plant shape is beautiful. Water and fertilizer should be properly controlled after pruning, because the consumption of aboveground parts is reduced.
maintenance management
Zhu Jin is a positive tree species and should be moved outdoors in early May and placed in a sunny place. At this time, it is also the growing season of Fusang, so we should strengthen the management of fertilizing water, loosening soil and pulling weeds. Apply dilute liquid fertilizer every 7- 10 days, and water it according to the wet and dry conditions of the basin soil. Too dry or too wet will affect flowering.
Insufficient light, buds are easy to fall off, flowers shrink, and the sunshine should not be less than 8 hours a day. Fusang has a great demand for fertilizer, so it should be replenished in time when it is cultivated. Potted hibiscus usually leaves the house in April. Before going out, change pots, trim them properly and keep a beautiful crown. During the growing period, there should be enough water, no water shortage and no waterlogging. Usually, water should be used once a day, once in the dog days and once in the morning and evening. The ground is often watered and humidified to cool down to prevent the tender leaves from burning and the flowers from falling prematurely. After cooling at 10, move it into the greenhouse and keep the temperature above 12℃. Management should be cautious after autumn, and pay attention to less fertilization in the later period to avoid sprouting autumn shoots. Autumn bamboo shoots are tender and weak in cold resistance, and will be frozen when the weather is cold.
How to breed hibiscus flowers?
Breeding methods of hibiscus flowers: changing pots; Before moving out in April every year, the pots should be changed.
The soil should be loose and fertile sandy soil. When changing pots, put in new culture soil, cut off some excessively dense curly fibrous roots, apply sufficient base fertilizer, and slightly add phosphate fertilizer to the bottom of pots.
Pruning; After moving out of the room, it will be trimmed. Except for 2-3 buds at the base, all branches will be cut off at the upper part. Pruning will promote the development of new branches, the new branches will grow more vigorously and the plant shape will be beautiful. Water and fertilizer should be properly controlled after pruning.
Temperature; After the first frost and before beginning of winter, you must move indoors, because Fusang is not frost-tolerant. Overwintering temperature is not lower than 5℃ to avoid freezing injury; Not higher than 15℃, so as not to affect dormancy.
When the weather is cold, cover it with paper or plastic film to keep warm. Move the house for the first time every day, open the window for ventilation, pay attention to the dry and wet changes of the basin soil, and water it properly.
In the coldest days, watering can prevent freezing injury, but fertilization should be stopped.
How to raise hibiscus flowers?
Breeding method of hibiscus flowers: changing pots and pruning: here, it is aimed at potted hibiscus flowers, and the soil should be fertile and loose sand.
Potted hibiscus flowers should be moved indoors every winter when the temperature drops, otherwise it will freeze the hibiscus. You can keep a low profile until next spring.
After a winter of hibiscus flowers, the soil in the pot is insufficient in nutrients, and the soil may be a little hardened and need to be changed. When changing pots, new culture soil should be used, and sufficient base fertilizer, mainly phosphate fertilizer, should be applied in the pots.
It is also necessary to cut off some dense fibrous roots of plants to make the main stems of plants grow better. In order to keep it doesn't matter, you can also trim it and cut off most of the new buds, leaving only 2-3.
Watering and fertilization: after moving outdoors, give hibiscus sufficient light and nutrients during the growing season, and always pay attention to the looseness of fertilizer, water and soil. Generally speaking, dilute liquid fertilizer should be applied once a week or so.
If you water it, you should pay attention to controlling the amount of water. You shouldn't work too hard and you shouldn't be too wet. Generally, you can water the basin soil when it is slightly dry. After autumn, we should do a good job in fertilization management and reduce the number and dosage of fertilization.
What are the breeding methods of hibiscus flowers?
Hibiscus originated in China, and it is a well-known flower, also known as the big red flower. It is deeply loved by people because of its bright colors and fragrant flowers.
However, the breeding conditions of hibiscus flowers are harsh, so these plants need careful care to produce beautiful flowers. However, hibiscus flowers are not so easy to survive.
Let's take a look at the breeding methods of hibiscus flowers. I. Introduction of Fusang Alias: Fusang, Zhu Jin and Dahonghua. Fusang is loved by people all over the world because of its easy cultivation and long viewing period.
Malaysia in Asia, Sudan in Africa, Fiji in Oceania and Hawaii in North America are designated as national flowers or state flowers respectively. This shows the position of Fusang in Asia, Africa and other continents.
Originally from China, it is distributed in Fujian, Guangdong, Guangxi, Yunnan and Sichuan provinces. Born in sparse forests in mountainous areas, it is easy to grow, with strong resistance, few pests and diseases. It likes warm and humid climate, is not cold-resistant, and requires sufficient sunshine.
It grows well in areas where the average temperature is higher than 10℃. Like light, not tolerant of shade, suitable for rich organic matter, pH 6.
5~7 slightly acidic soil, planted as a flower hedge in the south, potted in greenhouse in the north of the Yangtze River basin. Second, the cultivation method of hibiscus 1, soil.
It can adapt to all kinds of soils, but the fertile and loose slightly acidic soil is the best. 2. temperature.
The optimum temperature for the growth of hibiscus is 15~25℃, and 10 ~18℃ in March of the following year. The temperature should not be lower than 5℃ in winter, otherwise the leaves will turn yellow and fall off.
It is vulnerable to freezing damage below 0℃, but it can still grow normally at high temperature above 30℃. Fusang is a strong positive plant, and it needs sufficient light to grow and bloom normally during the growing period.
If the light is insufficient, the flower buds are easy to fall off, the flowers are small and the color is dim; However, when the sunlight is too strong, plants will burn, and shading measures should be taken. 3. Moisture.
During the growing period, the basin soil is kept moist, and the stems and leaves grow rapidly. If the water supply is insufficient, the leaves will wilt, turn yellow and fall off easily. Watering on weekdays depends on the wet and dry conditions to avoid being too wet.
Water it in the morning and evening in midsummer and in the afternoon in spring and autumn. In winter, due to the low temperature, water quantity should be strictly controlled, otherwise, plants are prone to freezing injury. In addition, water should be sprayed frequently during the growth period.
4. Trim: Trim after moving out of the room. All branches were cut except for 2~3 buds at the base. Pruning can promote the growth of new branches, which will be more vigorous and the plant shape will be more beautiful. Water and fertilizer should be properly controlled after pruning.
5. Management: Management is also very important. In early May, when outdoor activities are carried out in sunny places, the management of fertilizing water, loosening soil and pulling weeds should be strengthened. Apply dilute liquid fertilizer every 7~ 10 days, and pay attention to the wet and dry conditions of the basin soil when watering. Too dry or too wet will affect flowering.
Management should be cautious after autumn, and pay attention to less fertilization in the later period to avoid sprouting autumn shoots. Autumn bamboo shoots are tender and weak in cold resistance, and will be frozen in cold weather.
6, pest control: after entering the room in winter, if the indoor ventilation is poor and the light is insufficient, we should pay attention to improving the ventilation and light transmission conditions of the indoor environment, combined with drug control. A small amount of scale insects can be brushed off gently with a brush.
Finally, seeing here, the cultivation method of hibiscus flowers is completed. Friends who like to plant hibiscus flowers, hurry to buy hibiscus flowers, or you can plant them yourself. In warm places, hibiscus flowers can be planted as flower fences, which is a good decorative fabric.
Planting method of hibiscus flowers
Key points of cultivation (1) Soil Fusang does not require much soil, and can generally adapt to it except saline-alkali land.
But it is best to use loose, fertile and well-drained slightly acidic loam or clay. The soil in the upper basin can be made into nutrient soil with 4 parts loam and 1 part dry manure.
(2) Insufficient light, flower buds fall off, flowers shrink, and the color is dim. Therefore, Fusang should have more than 8 hours of light every day.
However, shade is needed in midsummer to prevent the scorching sun from burning plants. Cultivate the soil once in early spring and weed and cultivate the soil once every season.
Every year after 10, potted hibiscus flowers should be moved to room temperature 15~22℃ for indoor cultivation, and attention should be paid to ventilation and proper illumination after entering the room. (3) Fully water Fusang.
Usually water once a day, so as to be thorough. Watering once every morning and evening in dog days, spraying water to the ground for many times to cool down, increasing air humidity and preventing flowers and leaves from falling off prematurely.
In winter, we should reduce watering and stop fertilizing to make it safe for the winter. (1) It needs a lot of "fertilizer" to fertilize hibiscus. When nursery seedlings are raised or potted, 50 grams of dry pig manure is applied to each plant and mixed with phosphate fertilizer and decomposed compost to form base fertilizer; Topdressing 0.2% urea aqueous solution and weak fertilizer mainly containing phosphate fertilizer 2~3 times a month.
In case of rainy season, compound granular fertilizer can be applied to roots instead, each plant 100g. 4. Hibiscus usually adopts the methods of cutting and grafting. Two-year-old stout branches with the thickness of 65438±0cm were selected in early spring and planted in well-ventilated coarse sand. Sand should be washed with water and disinfected with boiling water. The thickness is 20 cm, and the branches are cut into two thirds of the soil. Keep the temperature 18~25℃ and the relative humidity 70%~85%.
The diameter of the flowerpot used for cutting is 15cm, and one flowerpot is planted for every three plants. 5, pests and diseases The pests and diseases of Fusang include aphids, scale insects and so on.
These pests and diseases are most likely to occur at the turn of spring and autumn, and can be controlled by spraying organophosphorus pesticides. For more details, please click here: njyl/article/s/581094-314982-13.
The cultivation methods of hibiscus flowers in northern dwellings are as follows
1, Fusang likes a warm and humid climate, is not cold and freezing-resistant, and is shade-tolerant, so it should be grown in a sunny and ventilated place. The requirements for soil are not strict, but it grows best in fertile and loose slightly acidic soil, and the temperature in winter is not lower than 5 degrees Celsius. 2. Choose loose and weak acid soil with abundant sunshine, warm and humid climate, fertile soil and good drainage. 3. Change pots and trim potted plants.
There are three things to do when changing pots: first, put in new culture soil; The second is to cut off some fibrous roots that are too dense and curly; The third is to apply plantar fertilizer and slightly add phosphate fertilizer to the pelvic floor. In order to maintain a beautiful tree shape and a large number of flowers, according to the characteristics of strong germination ability of hibiscus, pruning and shaping can be carried out before and after leaving the house in early spring. Except for 2-3 buds at the base, all the upper branches were cut off. Pruning can promote the new branches to grow more vigorously and the plant shape is beautiful.
Water and fertilizer should be properly controlled after pruning, because the consumption of aboveground parts is reduced. At the beginning of April and May, the positive tree species should be moved outdoors and placed in a sunny place. At this time, it is also the growing season of hibiscus, so management work such as fertilization and watering, loosening soil and pulling weeds should be strengthened.
Apply dilute liquid fertilizer every 7- 10 days, and water it according to the wet and dry conditions of the basin soil. Too dry or too wet will affect flowering. Management should be cautious after autumn, and pay attention to less fertilization in the later period to avoid sprouting autumn shoots.
Autumn bamboo shoots are tender and weak in cold resistance, and will be frozen when the weather is cold. 5. Pest control The main pests of Fusang are aphids, chaff vectors, cotton blowing vectors and mites (commonly known as red spiders).
These pests belong to piercing-sucking pests. That is, using their mouthparts to pierce the leaves or epidermis of plants and suck the juice of plants.
The leaves of injured plants lose green and grow weak, which reduces the ornamental value. After the occurrence of aphids and mites, aphids and mites can be diluted with drugs such as aphids, mites and mites, and then sprayed on the leaves to kill them once a week, usually 2-3 times.
Bran and cotton foaming agents can damage leaves and epidermis. Generally, imidacloprid drugs or their modifiers can be diluted by a certain number and sprayed to kill the damaged parts. If the damage is serious, it can be 10 once a day, and it can be basically extinct after three times.

0 1
Soil. Generally speaking, hibiscus can adapt to all kinds of soil, but it is better to use fertile and loose weak acid soil.
02
Light and temperature. Hibiscus is a strongly positive plant, so its growth needs enough sunlight. However, the sunlight should not be too strong, so as not to burn plants, and some shade protection can be appropriately added. The suitable temperature for the growth of hibiscus is 15℃-25℃. When the winter temperature is too low or the daily temperature drops, plastic film should be properly covered for insulation.
03
Water it. In winter, the soil in the basin can be kept moist, and it is usually watered every 5- 10 day, and the amount of water should not be too much to prevent root rot caused by low temperature and high humidity soil. Note that when the branches and leaves of hibiscus become Huang Shi, the indoor air humidity should be appropriately increased.
04
Change the basin. Before moving out in April every year, the pots should be changed. When changing pots, we should also put in new culture soil, apply sufficient base fertilizer and subtract some too dense fibrous roots.
05
Trim. After moving out, hibiscus flowers can be pruned, which not only keeps the beauty but also promotes the growth. Generally speaking, all branches are cut off except the basic branches with 3-4 buds.
06
Pest control. Common pests are aphids and mites. Therefore, aphid mites, aphid mites, aphid mites and other drugs can be diluted with water and sprayed on leaves to kill them. Once a week, usually two or three times can be eliminated.
How to raise hibiscus flowers
[Cultivation techniques]
Propagation: Generally, cutting is the main method, and other methods are rarely used.
The survival rate of cutting in spring and autumn is high, and the survival rate of cutting in pot is high and fast. Generally, flowers can bloom in one year. Generally, two-year-old strong branches should be selected, or semi-lignified strong branches of the same year should be used. It is best to cut the middle part of the lateral branches into cuttings about 15 cm long, with 5-7 knots. The inserted bed soil is made of coarse sand or silica with good drainage and strong air permeability. After disinfection, put it under the bed with a thickness of about 15-20 cm. The lower blades of cuttings should be leveled with a sharp knife and cut off in time, with a depth of 1/2. Immediately after insertion, water 1 time, cover with plastic film, keep proper temperature and humidity, make it moist but not moist, and have good drainage and ventilation. Later, gradually exposed to the sun, keeping the temperature of 18-25℃ and the relative humidity of 70%-80%, it usually takes 20 days to take root, and 1 month can be put into the pot.
Management: Hibiscus seedlings should be planted in sunny, fertile and loose soil with good drainage. Don't be too big for potted plants. Generally, clay pots with a diameter of 1.5 cm should be used, and the soil should be released year by year. Pots should be sandy loam rich in organic matter and mixed with 65,438+0% decomposed cake fertilizer or dry manure. For newly planted seedlings, the soil should be compacted and watered, shaded for a few days first, and then moved to the sunny place for cultivation, which is conducive to survival. Usually pay attention to moderate watering, which will affect flowering. When it is hot in summer, water it in the morning and evening, and spray water on the leaves. Applying cake fertilizer solution 1 time per week can ensure flowering. When the seedling height is about 15 cm, pull out 1-2 times to promote new shoots. Before the first frost is moved into the greenhouse or indoors every year, the room temperature should not be lower than 5℃, otherwise it will be easily damaged by freezing, and it is best to keep it at 10℃. After moving into the room, open the window every day for ventilation, water properly and control fertilization. When the weather is too cold, watering helps to prevent frostbite. Moving out of the room should be carried out after the temperature rises in the second year. Combined with changing pots and replacing new culture soil, pruning was carried out at the same time. 2-3 buds should be left from the base of each lateral branch, and the upper part should be cut off to make it grow full and symmetrical new branches again, so that it can grow vigorously and flourish.
The pests and diseases of hibiscus are aphids, scale insects and bituminous coal diseases. Insect pests can be killed manually or sprayed with dimethoate 1000 times; The prevention and control method of bituminous coal disease is mainly to improve environmental conditions, mainly through adequate illumination and good ventilation.

Hibiscus flowers are brightly colored and have a long flowering period. The so-called "Buddhist Mulberry Four Seasons bloom". It is a famous ornamental flower, suitable for planting in southern courtyards and corners. Potted plants are common flowers in balconies and indoor rooms.
How to improve the ornamental value of hibiscus flowers
How to raise hibiscus flowers Hibiscus is a famous flower in China, which originated in the south of China.
Cultivation is very common in South China. Also known as Hibiscus, Zhu Jin, Fosang, Safflower, Hibiscus, Sunflower, Flower on Flower and Peony, they are evergreen shrubs or small arbor plants of Hibiscus in Malvaceae.
Its flowering period is long, almost all year round, and it is the most prosperous in summer and autumn. Flowers are big and bright, blooming at dusk, colorful and flowery. There are many varieties and colorful flowers. According to petals, it can be divided into single petals and compound petals, and according to colors, it can be divided into red, pink, yellow, cyan and white. The crimson double petal is slightly similar, so it is called Zhu Jin.
The flower pattern is axillary trumpet-shaped, with large flowers, drooping or straight stalks, erect and multi-branched stems, alternate leaves, broadly ovoid to narrowly ovoid, similar to mulberry leaves and round leaves, 7- 10 cm long, 3 main veins, sharp or pointed apex, rough serrated or notched leaf margin, nearly entire base, and bald or slightly sparse dorsal veins. Fusang is a strong positive plant, which likes warm and humid climate, is not cold-resistant, cold-resistant, frost-resistant and shade-resistant, and is suitable for growing in sunny and ventilated places. The requirements for soil are not strict, but it grows best in fertile and loose slightly acidic soil, and the temperature is not lower than 5℃ in winter.
Hibiscus is simple in management and widely used in landscaping in subtropical areas. In addition, it is also an important greenhouse and indoor flower in the Yangtze River basin and its north area. The maintenance of hibiscus flowers should pay attention to the following points: 1. Changing pots and pruning Before moving out in early spring and April every year, change pots, and change new culture soil when changing pots. Potted plants should choose loose and fertile sandy loam; Cut off the dense fibrous roots, apply foot fertilizer, and slightly add phosphate fertilizer to the basin bottom.
In the construction of hibiscus, according to the characteristics of strong sprouting ability of hibiscus, all branches are cut off except for 2-3 buds at the base, which makes the growth more vigorous and the plant shape more beautiful. 2. The management of hibiscus during the growing season, that is, after leaving the house in early May, move it outdoors and put it in a sunny place, strengthen the management of fertilizer and water, loosen the soil and pull up weeds.
Pay attention to less fertilization in late autumn to avoid sprouting autumn shoots, because autumn shoots are tender and weak in cold resistance, and they will freeze when it is cold. Therefore, we should also pay attention to the need to move indoors to keep warm after the first frost and before winter. The overwintering temperature should not be lower than 5℃ to avoid freezing injury, but should not be higher than 15℃ to avoid affecting dormancy.
Pay attention to the dry and wet changes of basin soil and water it properly. In the coldest days, watering can prevent freezing injury, but fertilization should be stopped. Function of Hibiscus: In garden application, Hibiscus has bright and dazzling flowers, which are distributed in front of pavilions, roadside and south wall in Chi Pan. Potted hibiscus is suitable for living room and porch decoration.
At the same time, it can also be used as medicine, and the flowers, leaves and roots of hibiscus can be used as medicine. The leaves are sweet and dry, and have the effect of clearing away heat and toxic materials.
Flowers are sweet and cool, and have the effects of clearing away lung heat, resolving phlegm, cooling blood and detoxifying. External use can treat carbuncle swelling and sores. Recently, it was found that it can also lower blood pressure, and the stem bark can be used to make ropes and sacks.
Influence of Hibiscus on Home Environment There are many kinds of Hibiscus, which are famous ornamental flowers and trees. Because the plants in Zhu Jinzhong are relatively large, they are mostly used to beautify fences or gardens and watch flower hedges. In the south, they are scattered in Chi Pan, in front of pavilions, beside roads and walls, to beautify the environment around the home and add emotional appeal.
Furthermore, hibiscus can also be made into potted plants. Hibiscus flowers are bright and colorful. Potted hibiscus flowers are suitable to be placed in the living room and porch to show their enthusiasm and hearty breath, so that tenants can shine at the moment of entry, feel happy and relaxed under the influence of hibiscus flowers, and feel the enthusiasm of the host family. This is a warm and comfortable home for you. Moreover, even if hibiscus does not bloom at this time, its leaves, if monochrome, are green and bright; If it is hibiscus, its leaves are colorful, as beautiful and unique as its flowers.
Fusang is not only beautiful, but also not as delicate as other flowers. It is easy to cultivate and manage, and it is loved by people because it is taken from few people and enjoyed by many people. Generally speaking, hibiscus flowers are scattered in front of pavilions, roads and walls in Chi Pan, while potted hibiscus flowers are suitable for living room and porch decoration.
Fusang is a kind of plant that enjoys foliage and flowers. It symbolizes enthusiasm and hearty, and implies the beauty of being slim, considerate and fresh forever. Therefore, hibiscus flowers are suitable for modern minimalist home style, because modern minimalist home style is characterized by simplicity and lightness, and at the same time, it is boldly used in personality, color and shape. Green trees and red flowers are the "wild" wind in the home industry. There are not so many rules in the choice of green plants.
Therefore, it is more natural, fresh and lively with warm hibiscus flowers. Furthermore, you can also try Chinese pastoral style, featuring natural and fresh folk customs. The green hibiscus flowers are dotted with red flowers, which are simple and refined and close to nature. Moreover, for hibiscus flowers with brocade leaves, they have natural colors, so they are closer to nature and more slender and considerate.
Some relations between hibiscus flowers and geomantic omen: hibiscus flowers are brightly colored, representing a vibrant day. Therefore, if you plant a pot of hibiscus in your Chi Pan, in front of the pavilion, by the roadside and by the wall, or put a pot of hibiscus in the living room and porch, your home will look vibrant, enthusiastic and hearty. How can you not bring good feng shui? However, because "Fusang" and "mourning" are homophonic, it is generally called "Zhu Jin". In addition, there is a beautiful legend about Hibiscus, because Hibiscus is the state flower of Hawaii. Seeing hibiscus flowers will remind people of southern beauties playing on the beach in grass skirts under the blue sea and blue sky.
It is said that indigenous girls put hibiscus flowers above their left ears to mean "I hope to have a lover" and above their right ears to mean "I already have a lover". What about both sides? I already have a lover, but I hope to have another one. Should you plant a hibiscus flower at home, suggesting to the guests that your family is full of love and warm and heartfelt to the guests?
How can we keep hibiscus flowers from sprouting? All the hibiscus flowers in China have sprouted these days, and there are none.
Fusang is a strong positive plant, and the daily light should not be less than 8 hours. At this time, it not only grows vigorously, but also produces many bright colors.
If the light is insufficient or too cool, the new branches will grow thin, the flowers will be few, and the leaves will be dim or even fall off. So potted flowers should be placed in sunny places.
Fusang avoids the sultry weather. Therefore, in the high temperature period in July and August, shade should be properly provided around noon under the scorching sun.
There are several reasons for hibiscus falling buds and flowers: 1 Summer falling buds are generally caused by insufficient nutrient supply. Because in summer, hibiscus is in a vigorous growing season, if the nutrient supply is insufficient and the metabolism is unbalanced, bud drop will occur.
In late autumn, hibiscus is a southern flower with poor cold tolerance. In the late autumn in the north, it is necessary to move to the greenhouse in time to spend the winter safely. If you don't move to the greenhouse in late autumn, or if the indoor temperature is too low and the light is insufficient, it may appear. The room temperature should be above 18 degrees Celsius. Improper management of fertilizer and water affects the normal physiological function of root system and causes bud falling.
Don't water too much, the pot soil should be dry and wet, and excessive water content in the pot soil will also cause buds to fall off. If the roots are full of pots, not changing pots in time will also cause buds to fall. In this case, we can change pots next spring, remove some residual soil and replace them with fresh and fertile soil. Proper pruning and pruning should be carried out after changing pots.
4. In the germination stage of hibiscus, dilute liquid fertilizer and nitrogen and phosphorus compound fertilizer should be applied every 7- 10 to 2 times to facilitate the growth and flowering of plants. Once the bud is formed, it is necessary to properly control the fertilizer and water, bloom in June-June 10, and topdressing the phosphorus-based fertilizer once a month 1 time to prevent axillary buds from sprouting on the branches in the current year, otherwise the secondary buds will grow vigorously, which will cause nutrient transfer in the branches and cause buds to fall off.
