How to grow Camellia in potted plants? Culture methods and matters needing attention of Camellia

Camellia, also known as Camellia, Camellia, etc., are shrubs or small trees of the genus Camellia in the Theaceae. They bloom for a long time and bloom from October to May of the following year. The blooming period is usually from January to March. Because of their graceful plant shape, bright green leaves and colorful flowers, they are cherished by the horticultural circles of the world. Let's take a look at the breeding methods and matters needing attention of camellias.

Distribution of Origin of Camellia

There are about 2000 varieties of camellias, which can be divided into 3 categories and 12 flower types. Originated in southwest China, it is mainly distributed in the Yangtze River and Pearl River basins of China, Yunnan and Korea, Japan, India and other places. Most of the open fields in central and southern China have been cultivated for 1400 years, while potted plants are planted in greenhouses in the north. There are wild species in Sichuan, Taiwan, Shandong, Jiangxi and other places.

Growth habits of Camellia

Camellia fear the wind and enjoy the sun, the terrain is high and cool, air circulation, warm and moist, good drainage, loose and fertile sandy loam, loess or humus, pH5.5~6.5 is the best. The optimum temperature is between 20 and 32 ℃, stop growing when the temperature is above 29 ℃, and the leaves will be anxious at 35 ℃, which requires a certain temperature difference. The environmental humidity is more than 70%, and most varieties can withstand the low temperature of-8 ℃. In the south of Huaihe River, they can survive the winter naturally and like acid soil, and require good air permeability. The root hair is developed and can usually be cultivated with a mixture of peat, sawn wood, laterite, humic soil or above. Camellias can be shaded in spring, autumn and winter, and 50% shading can be used in summer.

Propagation methods of Camellia

1. Cutting propagation: the cutting propagation of camellias is the most convenient, and the cutting time is the most suitable in September, or in spring. Select the well-growing, semi-lignified branches, remove the basal leaves, retain the upper 3 leaves, cut them into an oblique mouth with a sharp knife, immediately soak the incision in 200~500ppm indolebutyric acid for 15 minutes, dry it into a sand basin or vermiculite basin, water the wound for about 40 days, and take root for about 60 days. The cuttings treated with hormone took root 2-3 months earlier than those without hormone. Vermiculite is used as a slotting bed, and it takes root much faster than a sand bed.

2. Breeding by grafting: choose appropriate varieties such as tea cup tea or Camellia oleifera as rootstock and connect valuable camellias. The connecting time is usually between Ching Ming Festival and the Mid-Autumn Festival. First plant the rootstock in the flowerpot, cut off about half of the joint with a knife, the incision should be smooth, then make the cut of both sides closely fit, wrap it with plastic film, drench the rootstock twice a day, and heal after 60 days. At that time, it can be cut off and planted in the shade of trees to avoid direct sunlight. In February of the following year, the tail of the rootstock was cut off with a knife and then planted.

3. Leaf cutting propagation: leaf cutting propagation is generally used in camellia propagation, but some valuable varieties are also used because of the limitation of the source of branches or considering that the shape of the tree will be affected after sampling. Using mountain mud as the cutting substrate, it can be mixed with 1 stroke 3 river sand to facilitate ventilation and drainage, and the matrix is stored in a tile basin, and then cut in the basin. Leaf insertion is best carried out in the rainy season, take one-year-old leaves as leaf insertion material, too old is not easy to root, too young and easy to rot. Insert about 2 cm into the soil, press the soil after insertion, pour enough water, and then put it in a cool and ventilated place. Generally, it can take root in 3 months, and it can sprout and branch in the next spring.

4. High-cutting propagation: the most important feature of the high-altitude cutting method is that it can give new life to all the weak twigs on the camellias that should have been pruned. And this method has the advantages of high survival rate, quick rejuvenation and early flowering. The method is as follows: the thin branches that need to be trimmed off are girdled in an appropriate position, and the girdling length can be between 5-8 mm (generally the upper part can be left into 15-25 cm branches). The plastic film of appropriate size is bound, and the disinfected peat soil or rotten leaf soil is added into the film, and after 7 days, the lower part of the plastic film is peeled 5-8 mm, which is called double-ring peeling high insertion method.

5. Tree grafting propagation: grafting propagation of camellia has many advantages, which can maintain the excellent characters of varieties, accelerate plant growth and make it take shape rapidly and produce on a large scale. It is especially important to save panicle strips, especially for those rare varieties with few sources of panicle strips. The suitable grafting time is from June to July, when the new leaves of camellia scion have been unfolded, the temperature is high, the grafting wound heals quickly and the survival rate is high. The grafting method is the cutting method in the grafting method, which is often called "high grafting head" because of the high position of grafting.

Culture methods of camellias

1. Soil demand: soil is the fundamental condition for the growth of camellia, so the choice of soil is also very important. generally, when we choose soil, we should choose soil with high humus and slightly acidic soil. the pH value of general soil is between 5 and 6.5.

2, the temperature is suitable: the general camellia suitable growth temperature is 18-25 degrees, the environmental temperature is too high or too low is not conducive to the growth of camellia, especially in winter, move the plants to the indoor growth, move the plants to the balcony at noon, and pay attention to sunscreen in summer to prevent the temperature from being too high.

3, appropriate watering: generally camellias like to grow in a humid environment, so we should mainly water camellias, but we should pay attention to keeping the soil not too dry or too wet, generally watering more in spring and summer. this is also conducive to the growth of camellias, pay attention to less watering in winter, watering every two or three days is better.

4, appropriate fertilization: Camellia is a fertilizer-loving plant, so in the process of breeding, pay attention to fertilization, generally in the growing period, add phosphorus and potassium fertilizer, which is also conducive to the growth of camellia, so that the flowers bloom more luxuriantly, at the same time, the main fertilization should not be too much.

5. Regular pruning: pruning is also very important. When camellia buds are dense, regular pruning is recommended to cut off weak branches and arrange buds. At the same time, it can also promote the absorption of nutrients.

6. pest prevention: Camellia is also easy to develop diseases and insect pests, generally there are two kinds of diseases and insect pests, black mold and anthrax, pay attention to spraying some drugs to eliminate diseases and insect pests for camellia during the period of diseases and insect pests, which can play a good role in promoting growth.

Pot Culture method of Camellia

1. Pot soil selection: according to the growth characteristics of camellia, it is appropriate to choose slightly acidic, loose, fertile and well drained mixed soil as basin soil, especially pay attention to good drainage, do not use calcareous soil, the proportion of mixed soil is 6 parts of red soil, 3 parts of orchid mud (rotten leaf soil), 1 part of fine sandy soil, the basin size should be moderate, should not be too large or too small. In general, the ratio of pot to seedling is that a camellia with a height of 40 cm and a crown of 20 cm should be planted in a purple sand basin or tile basin with a diameter of about 20 cm, and so on.

2. potting time: the potting time of camellia is November in winter and February to March in early spring. At this time, the buds are enlarged and the flowers are in full bloom, which is the most suitable for pots. When the flowers are withering and the new roots are still sprouting, if you want to put them on the pot, you must pay special attention not to hurt the roots. Generally stop potting before and after the sprouting period, because at this time the new shoots are waiting to be sent and the leaves are developed, which requires a lot of water, such as pots, new roots are injured, which can easily affect the growth and development of the year. High temperature and severe winter season also avoid pots, so as not to cause plant atrophy and death.

3. The method of potting: first put 3 or 4 pieces of broken tiles on the bottom hole of the flowerpot, then fill part of the coarse soil, plant the seedlings in the pot, fill the root with fine soil, then slowly put the larger grain of potted soil all around the pot, gently shake the basin and press it by hand to make the potted soil close to the root. Large pots can be gently compacted down with bamboo sticks, and be careful not to hurt their roots. The basin soil should account for 4% of the basin height and 5% for watering.

4. Watering method: the seedlings in the new pot are kept moist, and can be watered like other potted seedlings after 2 months, and the watering times should be determined according to the climate, based on the principle of keeping the soil moist. Generally, it can be watered more in spring to meet the needs of sprouting and shoots, summer watering should be carried out in the morning and evening, water should be prevented in the Meiyu period, timely watering in autumn drought, and watering in winter should be carried out at noon to prevent the basin soil from freezing, and the soil is dry and frozen more intensely.

5. Fertilization method: Camellia does not like fertilizer very much, so it is not necessary to apply too much fertilizer. Generally, it is 10-11 before flowering, 4-5 months after anthesis, fertilizing for 2-4 times. General use of mixed fertilizers (human feces and urine, cake fertilizer, barnyard manure, phosphate fertilizer), it is best to give priority to phosphate fertilizer, nitrogen fertilizer as a deputy, in order to prevent branches from growing and flowers decreasing. All kinds of fertilizers must be fully mature and used, but rapeseed cakes and fish meal can be removed directly on the soil surface without decay, covered with a thin layer of soil, and allowed to slowly rot and seep into the soil for root absorption. The amount of fertilizer application should be mastered that the strong seedlings should be applied more, and the weak seedlings should be applied less or not. for the seedlings whose growth is too weak, replace the pot soil instead of fertilization, the effect is also very good.

6, shade against cold: Camellia likes warm and humid climate, too cold and heat are not conducive to growth and development. The potted camellias should be given plenty of sunshine in spring and Meiyu period, otherwise the branches are weak, which can easily cause bituminous disease and shell insects, or epiphytic moss, resulting in withered branches, senescence or death. The high temperature season in summer and autumn should be sheltered and cooled in time. When the temperature drops below zero in winter, it will cause buds to fall off or stamens to be frozen, affecting the quality of flowering. Therefore, the indoor overwintering temperature of potted seedlings should be kept at about 3: 4 ℃. If the temperature exceeds 16 ℃, it will promote early germination and serious defoliation and buds.

7. Disease control: the main pests of camellia are stem borer and shell worm. The main diseases are anthracnose on the leaf, black coal disease and mossy parasitism on the branches, so the damaged branches should be cut off and sprayed in time.

Matters needing attention in Camellia Culture

The main results are as follows: 1. Camellia is not suitable for intensity pruning, its flowers, leaves and buds develop for a long time, and the crown is formed evenly. Basically, there is no need for special pruning, just cut off disease and insect branches, over-dense branches, weak branches and truncated long branches.

2. Camellia is a multi-flowered tree species, especially on weak plants, if the buds are dense, it will consume too many nutrients, which is disadvantageous to the plant growth. Therefore, bud picking is an important part of cultivation and management, it is appropriate to leave 1 bud and 2 buds on each branch, only 3 buds at most, and keep a certain distance. The sparse buds can be used medicinally.

3. The flowering period of camellia is longer, and the whole flowering period is as long as half a year. Therefore, picking close to withered flowers in time is of great benefit to reduce nutrient consumption and enhance the tree potential.

How to grow potted camellias? Culture methods and matters needing attention of Camellia

Camellia is a flower plant of the genus Camellia of Theaceae, with green and chic leaves, large and colorful flowers, and very high ornamental value. It is a very good potted ornamental flower and is favored by flower lovers. So, how to grow potted camellias? The culture methods and matters needing attention of camellia are introduced as follows.

I. Culture methods of potted camellias

1. Place: Camellia prefer semi-shade and avoid the scorching sun, so it is suitable to be placed in a warm, moist, ventilated and transparent place. Breed camellia in spring to have sufficient light, summer should pay attention to shade, avoid direct sunlight, if the camellia on the balcony, often accidentally it will be sunburned to death. Camellia in the process of storage and transportation, it is necessary to prevent high temperature and air drying, otherwise buds and flowers are easy to fall off, affecting the quality.

two。 Temperature: Camellia likes warm climate, the suitable growth temperature is between 18-25 ℃, the initial flowering temperature is 2 ℃, it is slightly cold-resistant, the general variety can withstand the low temperature of-10 ℃ and summer heat, but more than 36 ℃ will inhibit its growth. The cultivation of camellia requires a certain temperature difference, and the best environmental humidity is above 60%. It can generally survive the winter naturally in the south of the Huaihe River, while the varieties of Camellia are slightly less resistant to cold.

3. Watering: Camellia bonsai culture to keep the soil moist, but not stagnant water, so as not to affect the growth when dry. In general, more water can be properly watered in spring, which is conducive to sprouting and sprouting; in summer, it is best to spray foliar water, so that the leaves are drenched thoroughly, not hot water should be watered, and the high temperature before and after noon should be avoided; proper amount of water should be watered in autumn; it is appropriate to water around noon in winter and spray water every two or three days.

4. Fertilization: Camellia likes fertilizer, pay attention to put a layer of base fertilizer in the basin soil, mainly phosphorus and potassium fertilizer, fertilization is the best mixture of rotten bone powder, hair, chicken feathers, rice chaff ash, poultry dung and calcium superphosphate. Usually should not fertilize too much, generally apply 2-3 times thin fertilizer water between April and May after flowering, and apply a slightly thicker water and fertilizer in autumn November. Camellia fertilizer pay attention to the proportion of phosphate fertilizer should be slightly larger, in order to promote the flowers colorful.

5. Pruning: Camellia growth is relatively slow, should not be over-pruned, generally only long branches and disease and insect branches, weak branches can be cut off. If there are too many buds on each branch, you can sparse the flowers, leaving only 1-2, and keep a certain distance, the rest should be picked as soon as possible, so as not to consume too much nutrients. In addition, it is necessary to pick the withered flowers in time, which can also reduce the consumption of nutrients, so as to facilitate the robust growth of camellia and form new flower buds.

6. Turn the pot: potted camellia had better turn the pot once in 1-2 years, and the new pot must be one size bigger than the old pot, which is beneficial to the root system development of camellia. The best time for turning the pot of camellia is in April in spring, of course, it can also be carried out in autumn. When turning the basin, combined with soil replacement, properly remove part of the hardened old soil, replace it with fertile, loose, breathable new culture soil, and first place a layer of base fertilizer.

Therefore, picking close to withered flowers in time is of great benefit to reduce nutrient consumption and enhance the tree potential.

[conclusion] Camellia likes warm, moist, well-drained, loose and fertile soil, so more attention should be paid to it in the process of conservation. The above introduces the cultivation methods and matters needing attention of camellia, hoping to be helpful to you!

Culture methods and matters needing attention of Camellia

Camellia is an attribute plant of Theaceae, which likes a warm and humid environment. Among the many flowers and plants, the flowering period of camellia is relatively long, and it can bloom from October to May of the following year. The colors of camellias are red, purple, white, yellow and other colors. Camellia is very popular because of its beautiful plant shape, thick green and glossy leaves and colorful flowers. Today, let's take a look at the cultivation methods and matters needing attention of camellia with the love of the editor. The soil of camellia culture method Camellia likes loose, fertile, well-drained sandy soil, loess and humus soil. Generally, when choosing soil culture, it can be cultivated with peat, sawn wood, red soil, humic soil, or above mixed substrate. The best PH for growing camellias is between 5 and 6.5. Soil with slightly acidic soil is the best. Camellia culture method of light, temperature camellia is a semi-shade plant, in the summer culture, need to give it shade. And after the Beginning of Autumn, the temperature dropped, camellia entered the flower bud to spend money, at this time to give it sufficient light. In winter, it should be kept indoors and in a sunny place. Camellia is a plant that shines for a long time, so it can only form flower buds in an environment that lasts 12 hours a day. Its growth temperature is 18-25 ℃. If it is higher than 35 ℃, its leaves will be burned. When breeding in winter, its temperature should be kept 3-5 ℃ earlier, and it can also endure a low temperature of-10 ℃ for a short time, but not more than 16 ℃ for a long time, otherwise it will promote germination and cause leaves to fall. The method of watering and fertilizing camellia has higher requirements for water, and its growth is ignored in neutral or alkaline soil. When watering, adding too much water will lead to rotting roots. If the basin soil can not be dry, it is easy to make the roots shrink because of water loss, so as to keep the basin soil and the surrounding environment moist. In the flowering period of camellia, don't spray water. When watering, do not pour water on its words, it is easy to cause mildew of flowers and shorten the florescence. When the camellia flowers fade, please remove the residual flowers in time. Winter watering is usually watered every three days to keep the pot soil moist. Camellia likes to be fat and usually applies sufficient base fertilizer when changing pots. In autumn and winter, rotten light liquid fertilizer should be applied once a week, and phosphorus and potassium fertilizer should be applied once or twice a week. When applying fertilizer, it can be poured with thin alum fertilizer. After sprouting in spring, apply thin fertilizer and water once every half a month, apply phosphorus and potassium fertilizer in summer, stop fertilizer for about one month in early autumn, apply alum fertilizer and water before flowering, and apply available phosphorus and potassium fertilizer when flowering, so that the flower is big and colorful and the flowering period is long. The shaping and pruning of camellia culture methods in the pruning of camellia, the dry and withered branches, diseased and weak branches, cross branches and overdense branches are mainly cut off. If the buds of the camellia affect the tree-shaped branches, the extra buds can be picked. If it is a potted camellia, you can trim it according to your preference, but when you trim it, you can't cut it too heavily, it will impress its growth. Camellia Note 1. When watering camellias, you must first store the tap water in a bucket for a day or two and let the chlorine evaporate. It is better to put 1% ferrous sulfate in the water to improve the water quality. 2. Camellia should not accept strong direct light, especially in summer and early autumn, it must be shaded. 3. When fertilizing camellias, if there is too much nitrogen fertilizer, it is easy to scorch the buds, and less or no fertilizer can be applied after flowering. 4. Because camellia is not cold-resistant, sometimes its flowering period will be delayed, which is quite normal. Conclusion: Camellia is an evergreen plant of the four seasons, its plant shape is beautiful, the leaves are thick green and shiny, and the flower shape is a traditional ornamental flower in China. It ranks eighth in the "Top Ten famous Flowers" and is also one of the most valuable flowers in the world. The above is the introduction of the camellia culture methods and matters needing attention brought by the editor. After reading the introduction of the editor, I believe everyone knows it better.
