How to cultivate and propagate Camellia in potted plants

Camellia is a very suitable ornamental plant, and it is also suitable for potted plants, so how to cultivate camellia flowers in pots? What are the propagation methods of camellia?

How to cultivate Camellia in potted plants:

1. Soil: soil is the foundation of camellia growth, and all nutrients of camellias are obtained from soil, so there is a high demand for soil. Generally, the soil contains high humus, PH value is between 5 and 6.5, and is slightly acidic. The best soil configuration is 50% of mountain soil, 40% of sawdust or edible fungus residue, 10% of cake fertilizer or livestock manure and 10% of phosphorus fertilizer.

2, temperature: the suitable growth temperature of camellia is 18-25 degrees Celsius, the temperature of the environment is too high or too low is not conducive to the growth of camellias, 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. Watering: 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, which is also beneficial to the growth of camellias. In winter, we should pay attention to less watering, and it is better to water every two to three days.

4. 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 as to make the flowers bloom more luxuriantly, at the same time, the main fertilization should not be too much.

5. Pruning: the pruning of camellias is also very important. When the buds of camellias are dense, regular pruning is recommended to cut off weak branches and arrange buds, which can also promote the absorption of nutrients by camellias.

6. Diseases and insect pests: Camellia is very easy to produce diseases and insect pests, generally there are two kinds of diseases and insect pests, black mold and anthrax. Pay attention to spraying some medicine to eliminate diseases and insect pests during the period of diseases and insect pests, which can play a good role in promoting growth.

7. Turning the pot: it is recommended to turn the pot and change the soil once after potted for one year, so as to provide a better growth environment, and the new pot should be larger than the old one to facilitate the expansion and development of the root system. The time to turn the basin should be in spring, April or autumn. In the process, try to remove some of the old roots, replace them with fertile and loose new soil, and combine them with base fertilizer.

What are the propagation methods of camellia:

1. Cutting propagation of camellia.

This method is the most simple, and the cutting time is the most suitable in September, or in spring, choose to grow well, semi-lignified branches, remove the basal leaves, retain the upper three leaves, cut into an oblique mouth with a sharp knife, immediately soak the incision in 200-500ppm indolebutyric acid for 5-15 minutes, insert it into a sandbasin or vermiculite basin after drying, 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. Propagation of Camellia by grafting.

Choose appropriate varieties such as tea cup tea or Camellia oleifera as rootstocks, pick up the valuable camellias, usually between Ching Ming Festival and the Mid-Autumn Festival, first plant the rootstocks in the flowerpot, cut off about half of the joint with a knife, the incision should be smooth, and then make the cut of both sides closely fit, wrap it with plastic film, drench the rootstock twice a day, heal after 60 days, and then cut off and plant. And put it in the shade of the tree 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 of camellia.

Camellia is generally propagated by branch cuttings, but some valuable varieties are limited by the source of branches, or considering that the tree shape will be affected after sampling, so the leaf cutting method is also used. 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 of camellia.

The most important feature of the high-altitude cutting method is that it can give new life to all the weak twigs that should have been trimmed off from the camellia. And this method has the advantages of high survival rate, quick rejuvenation and early flowering. The thin branches that need to be pruned are girdled in an appropriate position. (generally, the upper part can be left into 15-25 cm branches) the girdling length can be between 5-8 mm, the plastic film of appropriate size can be bound, and the sterilized peat soil or rotten leaf soil will be added to the film. After 7-10 days, the lower part of the plastic film will be girdled for 5-8 mm, which is called double-ring peeling high insertion method.

5. Tree grafting propagation of camellia.

Camellia is a plant that is difficult to survive. There are many propagation methods of camellia, among which grafting is the most commonly used. Grafting has many advantages, which can maintain the good characters of varieties, accelerate plant growth and make it take shape rapidly. and large-scale production, saving panicle, especially for those rare varieties with few sources of panicle, is particularly important. Camellia grafting technology: the suitable grafting time is from June to July, when the new leaves of the scion of camellia 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.

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.

The propagation method of potted camellia, cutting rooting and then soil culture (the simplest propagation method)

Camellia is very common in daily life. Any plant has its own method of reproduction, and camellia is no exception. There are many propagation methods of camellia, including sowing and propagation, cutting, grafting, leaf cutting and so on, but the simplest method is cutting. The survival rate of cutting propagation is very high, and it can take root after two months of good care.

1. The propagation method of camellia, the survival rate of cutting propagation is the highest.

The unique fragrance of camellias is deeply loved by people. With the progress of pot technology, camellias can also be raised at home. Earlier we talked about how to raise camellias and what is the efficacy and function of camellias. Now let's take a look at the breeding methods of camellias. The simplest propagation method with the highest survival rate of camellia is cutting. let's take a look at the steps of reproduction.

2. Cuttage propagation

The cuttage method for propagation of camellias is the easiest, and the best time is in September, and it is also possible in spring. Select well-growing, semi-lignified branches, remove the basal leaves, retain the upper leaves, cut the slant with a sharp knife, soak the incision in 200--500ppm indolebutyric acid 5-methylene for 15 minutes, then dry, then insert the sand basin or vermiculite pot species, wait for about 40 days for the wound to heal, during which time to continue watering. It usually takes about two months to take root.

It is also possible to select 3-4-year-old branches from late June to early July, peel 1-2cm stem bark around the lower end, reach to the xylem, and cut the cuttings after the callus at the wound expands. The cuttings should be cut as soon as they are cut. The best cutting depth is 1ax 3-1max 2 of the length of cuttings, and the row spacing is 5cm × 15cm. After insertion, press the matrix and spray water through a fine-hole spray can, place it in a semi-shaded place and spray water 1-2 times a day.

Note: keep the air humidity and substrate moist (it is better to store river water for 2-3 days or Rain Water for 2-3 days) and keep the temperature 20-25 ℃, and pay attention to gradually strengthen ventilation and receive sunlight, cuttings can take root in 1-2 months. After rooting, it is transplanted into the mud basin of caliber 7.5cm and managed normally after setting, which is one of the simplest propagation methods of camellia.

Third, the method of leaf insertion and reproduction

Camellia usually uses branch cutting propagation method, but some valuable varieties are limited by the source of branches, or considering the reasons that will affect their tree shape after sampling, so leaf cutting method can also be used, which is also a propagation method of camellia.

It is beneficial to ventilation and drainage, so mountain mud should be used as cutting substrate. The matrix is placed in a tile basin and then inserted into the basin. In the rainy season, one-year-old leaves can be used as leaf insertion material, (too old is not easy to root, too tender and perishable, annual is just right) insert soil depth of about 2 cm, after insertion, press the soil, pour enough water, and then put it in a cool and ventilated place. Generally, it can take root after 3 months, and it can sprout and branch in the next spring.

IV. Grafting and breeding

Select strong seedlings or camellia varieties that are easy to survive as rootstocks, cut off at about 4 cm from the ground, split 1.5 cm deep through the pith, use 1-2-year-old branches as scions, keep 1-2 leaves in the upper part of the scion, cut into wedges in the lower part, and insert into the split of the rootstock, the cambium of the two sides should be closely joined, and then fastened with plastic tape.

Note: after grafting, cover the top of the scion with a plastic bag and tie it with a belt below, but not too tight, so as to form water droplets in the bag and keep dripping on the rootstock. Add a wrapping paper bag to the outside of the plastic bag to block out the direct sunlight.

Camellia is a kind of potted plant that is easy to raise. It is absolutely harmless to raise camellias at home. Friends who like camellias can try to raise them at home. The above is the whole content of the breeding method of camellia. I hope I can help you.
