It is best to plant in spring in the north and autumn in the south. Ground planting should be selected with good drainage and strong water retention performance. Sandy loam rich in humus.
Camellia is a semi-negative flower, which needs to be shaded by a shed in summer. After beginning of autumn, the temperature dropped, and camellia entered the flower bud differentiation stage, so the whole plant should gradually receive sufficient light. In winter, it should be placed in a sunny place indoors. If the indoor light is too weak, camellia will grow poorly and be prone to pests and diseases. Camellia is a long-day plant. Flower buds can only be formed in the environment of day length 12 hours. The optimum growth temperature is 18-25℃, and the optimum flowering temperature is 10-20℃. Above 35℃, the leaves will be burnt. It is not cold-tolerant. It should be indoors in winter, and the temperature should be kept at 3-5℃. It can withstand the low temperature of-10℃ for a short time, but it cannot exceed 16℃ for a long time, otherwise it will promote germination and cause defoliation. The growing season should be placed in a semi-shady environment, and it is not suitable to accept too strong direct sunlight. Especially in summer and autumn, it should be shaded or placed in a cool place under a tree. Camellia likes warmth and is afraid of cold. The indoor temperature should not be lower than 5℃. If appropriate other measures are taken indoors at the temperature of 10℃ to 15℃, the Spring Festival can also bloom and the flowering period can last until March.
liquid manure
Camellia requires high fertilizer and water, and neutral and alkaline loam is not conducive to its growth. In the north, it is particularly important to pay attention to acidifying alkaline water before watering flowers. The specific method is to store tap water for 2 days to volatilize chlorine in the water, and then add an appropriate amount of ferrous sulfate (about 0.5% of water). Don't water too much, or the roots will rot easily. Pot soil can't be dry, otherwise the roots will shrink due to water loss, so it is advisable to keep the pot soil and surrounding environment moist. Don't spray water during flowering. In winter, it is generally dry indoors, so we should often spray water on the leaves of camellia to form a humid microclimate. But avoid spraying water in rainy days. Don't spray water on the flowers when watering, otherwise it will cause the flowers to rot and shorten the flowering period. Pick the residual flowers in time after the flowers wither. Watering in winter depends on the indoor temperature, usually once every three days. Keep the soil moist, and avoid accumulating water or pouring half water. Tap water should be put in a bucket for a day or two to allow chlorine to evaporate. It is best to put 1% ferrous sulfate in the water to improve the water quality.
Camellia likes fat. Generally, sufficient base fertilizer should be applied at the bottom of the basin when putting or changing the basin. In autumn and winter, due to the rapid development of flower buds, decomposed light liquid fertilizer should be poured once a week and topdressing 1 to 2 times of phosphorus and potassium fertilizer. Too much nitrogen fertilizer is easy to scorch the flower buds, and it can be applied less or not after flowering. It is best to apply thin alum fertilizer and water to avoid applying thick fertilizer. Generally, after germination in spring, dilute fertilizer water is applied 65,438+0 times every 65,438+07 days, phosphorus and potassium fertilizer are applied in summer, and fertilizer can be stopped for about 65,438+0 months in early autumn, then alum fertilizer water is applied before flowering, and quick-acting phosphorus and potassium fertilizer is applied when flowering, so that the flowers are bright in color and have a long flowering period.
Question 2: How to grow camellias? How to water camellia?
Camellia is planted in a wide area, and the conditions vary widely: it is wet in the southwest and dry in the northwest; It depends on the specific location and actual situation.
(1) Basic principles of watering camellia.
(1) the principle of watering camellia. The practice of watering camellia shows that "drying thoroughly and watering thoroughly" is the principle of watering camellia. "Dry" means that there is little water in the basin soil; "Permeability" means that the basin soil is not only dry on the surface, but also dry inside. Of course, "dry" because camellia is a fleshy root system and easy to rot.
Rot, causing death in severe cases. Even if the soil in the basin is loose and the running water is smooth, the watered camellia roots are comfortable and grow well.
(2) When the camellia is watered, there is an article saying that it is hot in summer "once a day. It is the most scientific to determine whether to water by listening and twisting.
(2) The special stage of camellia watering
(1) The budding stage of camellia is May-June, and then normal watering is resumed.
(2) The flowering period of camellia. In the flowering process of camellia, the water consumption is very large, and the water demand increases. If water is not poured in time, it will prevent the roots from rotting.
③ The seedlings of Camellia oleifera being cultivated at seedling stage should be properly watered to keep the soil moist, and then the general principle of watering Camellia oleifera is "dry thoroughly".
(4) The winter stage of Camellia starts from 10, and with the decrease of temperature, the evaporation of Camellia leaves decreases, ensuring its good flowering.
(3) The watering time of camellia in winter and summer
① The temperature is low in winter, especially in the morning and evening, and sometimes it freezes. Avoid the danger of direct freezing at night.
(2) It is hot in summer, so it is best to water camellia in the morning, followed by at night. The water to be watered should be close to the temperature of the pot soil to reduce the damage to camellia.
(4) water all kinds of camellias
Natural water camellia is best watered with natural water, because natural water has the following three characteristics, which is most suitable for camellia watering. This is one of the characteristics of natural water.
There is a nitride in the air, which often condenses into raindrops. If you encounter lightning, you can remove nitrogen oxide, which is the second characteristic of natural water.
There is more light water and less heavy water in the rain. Because heavy water is radioactive, it has an inhibitory effect on camellia. This is the third characteristic of natural water.
2 Taomi Water This kind of water is most suitable for watering camellia, killing two birds with one stone. Usage: Use only after dilution.
Tap water Because tap water contains hundreds of minerals and bleaching powder, it can be used to water camellia. Conducive to the growth of camellia.
(5) The temperature of the irrigation water.
Generally speaking, the water temperature of watering should be consistent with the temperature at that time, leading to premature death of fallen leaves.
The other is that the temperature of the poured water is higher than that of the basin soil. Generally speaking, it is also beneficial to the absorption and utilization of camellia.
(6) Analysis and rescue methods of camellia wilt due to lack of water.
When the cells in the branches and leaves of camellia wither due to excessive water shortage, if they are watered immediately, they will be watered gradually after they come back to life.
(7) The watering method when the teapot soil is cracked.
In summer, the temperature is very high, the water evaporates quickly, and the basin soil is dry and cracked, with good effect.
In winter, we should pay attention to the following points:
Daylighting: Camellia is a semi-negative flower, and it needs a shed to shade it in summer. After beginning of autumn, the temperature drops, which is prone to diseases and pests.
Temperature: Camellia likes warmth and is afraid of cold. The indoor temperature should not be lower than 5℃. The temperature 10℃ forms a humid microclimate. But avoid spraying water in rainy days.
Watering: Watering in winter depends on indoor temperature, usually once every three days. It is best to put 1% ferrous sulfate in water to improve water quality. & gt
Question 3: The cultivation method of camellia 1. Cultivation and management techniques of camellia. Soil: Sandy loam with rich organic matter, good drainage, good water retention and good air permeability is suitable. 60% sandy loam +40% humus can be used best. Third, irrigation water supply: like humidity, good drainage. Therefore, it is necessary to supply water in time, especially to prevent the phenomenon of dryness in the west due to water shortage or radiation heat damage of buildings in summer, so as not to hinder its growth. When the flower buds are divided into flowers, it is even more important not to cut off water or lack water, so as to avoid difficulties in planting flowers or causing falling flowers. Fertilization: We can mainly supply organic fertilizers: bone meal, plant ash and oil meal. Or calcium superphosphate lime or potassium chloride. The ratio of nitrogen, phosphorus and potassium is 5-3-2, and heavy fertilizer can be applied after flowering. Fertilization, especially nitrogen fertilizer, should be avoided during flower bud differentiation from May to July to avoid only sprouting leaves and buds. 5. Bud picking: The flower bud differentiation of camellia is mostly in June, but it can only be carried out in September ~ 165438+ 10 depending on the bud size like soybean. The principle of picking buds is: only one bud is left for each flower bud, and the bud must face upwards to avoid hurting the new bud. 6. Post-flowering treatment: 12 ~ 10 period: after flowering, the residual flowers should be removed as soon as possible and topdressing should be done immediately. Only 2 ~ 3 buds are left at the base of the branch, and the rest of the top can be removed. April-May: The water supply should be reduced, so that the branches with new buds will not be excessively elongated, so as to avoid reducing the number of buds in the subsequent flower bud differentiation. Breeding places are suitable for half-day breeding in a well-ventilated and cool environment. Avoid planting in hot, closed, humid or dry places. Planting and management of potted plants? Sowing in February-March every year, when the sap is about to flow out or begins to flow out, move the camellia oleifera seedlings into fertile and loose slightly acidic soil with good drainage and water retention performance. Potting, mixing potting soil with humus soil, mycorrhizal soil and fine sand in a ratio of 4: 3: 2, and then adding a small amount of phosphorus, potassium fertilizer or compound fertilizer. It is best to disinfect the mixed soil with 2% formaldehyde or other drugs. The planting site should be selected in a semi-shady place, and never planted in direct sunlight all day, so as to avoid burning leaves and flowers due to too strong light. When transplanting, try to stretch the root system, compact the soil and water it. 2? Shade camellia is a semi-positive plant, which likes semi-shade environment and is suitable for growing in warm climate and humid air. In order to prevent burns, it can be solved by setting up a sunshade or a sunshade net. If it's a potted flower, it's best to put it on the east side of the shade shed, so that you can get enough light in the morning and won't be exposed to the hot sun at noon and afternoon. 3? Water camellia is strict with water, and try to keep the soil moisture in a semi-humid state. Too dry soil will lead to poor growth, defoliation and even death; Too wet is easy to cause root rot. The amount and frequency of watering vary according to the season. There are many waters in spring and autumn, so it is advisable to knead the soil and loosen it after watering. Water less in winter, only water bonsai until the soil is wet to about 100px. In summer, the amount of watering is the largest and the number of watering times is the largest. Water the soil completely every time, but do not accumulate water. When watering bonsai, don't aim at the roots, so as not to impact the roots and expose them. 4? It is not advisable to apply too much fertilizer to camellia, especially for fertilizers that are not "dry" (that is, have strong fertility) such as human excrement and sesame cakes. Generally, soft fertilizers should be applied, such as soaked pig manure water and bean cake water. The amount of fertilization varies with the seasons: in spring, the growth potential of trees recovers, and after flowering, fertilization and watering begin, and with the acceleration of growth, the number of fertilization increases gradually; May-June, 4-5 times a month; July is the most prosperous season, watering 6 ~ 8 times; After August, it gradually decreased, and fertilization stopped after the autumn equinox (September) until the following spring. Fertilization and watering should take turns. 5? Anti-freezing camellia is afraid of cold and easy to get frostbite, so it is necessary to prepare for wintering in early winter, which can be done by painting the trunk or binding straw. In case of snowy weather, it can be solved by cleaning the snow on the trees and burning soil ash around the garden (which can increase the temperature of the garden). If it is a bonsai, move it into the greenhouse; When there is plenty of sunshine in winter, we have to move out at noon, and have a short period of sunshine and ventilation to make up for the shortcomings of insufficient light and poor ventilation. 6? Change pots and soil every year. Every time you change pots, you have to hand them a bigger size. When changing pots, all camellia plants are taken out together with the pot soil, and the soil near the pot is loosened with a small wooden stick to make its roots stretch. If the fibrous root is too long, it can be cut short appropriately. Before changing pots, put a tile at the small hole at the bottom of the newly implanted flowerpot (to prevent water seepage and flowerpot ... >; & gt
Question 4: The planting method of camellia Siji 1. Planting: Soils with excellent varieties, strong drainage and fertile sandy soil should be selected for ground planting. Spraying a new type of high-fat film on the soil surface can keep moisture and prevent evaporation, prevent sun and drought, keep warm and prevent freezing, prevent soil hardening, suffocate and isolate the source of pests and diseases, and protect seedlings from growing sturdily.
2. Illumination, weeding, watering and fertilization: Camellia also likes sunlight, but it is not suitable for direct exposure to too strong light. Summer and autumn should be shaded. Camellia has a high demand for fertilizer and water, so it should be kept moist at any time, fertilized reasonably as needed, and sprayed with new high-fat film to protect fertilizer and moisture.
3. Shaping and pruning: Camellia mainly cuts dry dead branches, weak branches, cross branches and over-dense branches, which obviously affects the branches of trees and sparse redundant buds. Stick a layer of calluses antiseptic film on the trimmed wound to protect the growth of wound healing tissue and prevent the infection of rotten bacteria.
4. Flowering control: Camellia is not cold-tolerant, how to delay flowering? It can also make camellia bloom eleven times. Controlling temperature, fertilizing water normally, and spraying Hua Zhuang Su on flower buds can make flower buds robust, petals plump, colorful and fragrant for a long time.
Question 5: How to plant camellia seeds (1) Seed harvesting and storage: harvest the fruits in autumn when they crack slightly, dry them in a cool and ventilated place indoors, and take out the seeds after the fruits naturally crack. Seeds should be sown immediately after collection, or treated with layered sand storage. After the fine sand is cleaned and disinfected with clear water, put the seeds and fine sand into a suitable container in layers, cover the upper layer with fine sand with a thickness of 5cm, then bury the container in the soil and check it regularly to prevent mildew and rodent damage.
(2) Seed treatment: Camellia seed coat is hard and needs to be treated to make the seeds germinate quickly and orderly. The following methods can be used: first, scrape off the seed coat with a sharp knife; 2. Soak the seeds in warm water at 40-50℃ for half an hour, then soak them in clear water at 20-25℃ for 5-6 days, and take the bottom seeds as sowing seeds; The third is to soak in gibberellin solution of 100μg/g/g for one day and night.
(3) Sowing: When the amount of seeds is large, the seedbed can be drilled with a width of 1m, with a self-defined length and a row spacing of1.5-20 cm. The seeds are placed in a ditch with a depth of 5cm according to the row spacing of 1-2 cm, and watered once after sowing. When the amount of seeds is small, you can sow in a pot, the soil thickness is 0.5- 1 cm, and you can spray water gently with a watering can.
(4) Post-sowing management: After sowing, cover the seedbed and flowerpot with plastic film or glass, keep the humidity, keep the temperature at 18-25℃, give sufficient illumination (avoid direct glare), properly ventilate every day, remove weeds in time, and control underground pests. When mold occurs, it can be disinfected by spraying with 0. 1% potassium permanganate. Germination begins at about 1 month. When the seedlings grow to 3-4 leaves, transplant them into flowerpots. Choose a pot with a diameter of 7- 10 cm, put it in a cool and ventilated place, spray water with a watering can, gradually increase the light after a week or so, and apply a thin layer of liquid fertilizer.
Question 6: How should camellia be planted? Known as sea willow in ancient times, it is an evergreen ornamental tree of Camellia, which sometimes grows into a shrub. Plant height varies from 0.5 meters to 5 meters, with different heights. Leaves alternate with thick leathery, bright surface, oval to oval. Flowers are solitary or symbiotic in leaf axils and branch tops. Ornamental varieties are mostly double petals, with different colors such as white, pink, rose and mosaic spots. The flowering period is 10 or the following spring and March, and it generally does not bear fruit. Some bonsai have more camellias, while others spend less. In order to make it more prosperous, some measures need to be taken.
1. Promote strong growth and multiple new branches. Because the flower buds of tea trees were formed on the new branches of that year, it is necessary to remove all the residual flowers on the plants in time in March-April when the tea leaves germinate. At the same time, the decomposed dilute liquid fertilizer, which is mainly nitrogen fertilizer, is applied three or four times, every 7 days or so 1 time.
2. Promote the formation of more buds. After 5 months, the new branches began to differentiate into flower buds and gradually formed buds. Pruning should be combined with cutting propagation at this time. Apply phosphorus and potassium fertilizer 1 fold immediately after pruning, and then apply 1 fold every 10 day, three or four times in a row.
3. Prevent flower buds from falling off In order to prevent flower buds from falling off, the pot soil should be kept moist, not too wet or too dry. Do not apply immature fertilizer or high concentration fertilizer. Generally, dilute phosphate fertilizer 1 time is applied from September to June, and fertilization is stopped in June, 1 1. When the buds grow to the size of soybeans, they will be thinned. Generally, only 1 bud is left at one branch end. If pests and diseases are found, spray them in time to prevent them.
4. Prevent direct sunlight and low temperature frostbite. In summer and autumn, bonsai camellia should be placed under outdoor shade shed to avoid direct sunlight. When the temperature is lower than 0℃ in winter, it should be moved indoors and placed in a sunny place. It is advisable to keep the indoor temperature at 3℃ ~ 5℃, and pay attention to proper ventilation. Camellia is a traditional famous flower originated in China, and now it has spread all over the world with tens of thousands of varieties. There are about 300 excellent varieties in China. Common cultivated white flowers: also known as Chiba (page) white, white flowers, flat and wrinkle-free. What kind of brocade: the pattern is the same as that of Baiyang tea, and the color is pink with white stripes or white petals with red stripes. Fish blood red: the flowers are similar to Baiyang tea, with deep red color and white spots on one or two petals of the outer wheel. Black tea flower: also known as Yang Guifei, the outer petals are wide and flat, and the inner petals are fine powder. Small five-star: the flower shape is similar to that of red and black tea, pink, with some mixed white spots, and the stamens are mixed in the finely divided petals of the inner wheel. Zhu Dinghong: Flowers are similar in shape to black tea. It is scarlet. Magnolia camellia: narrow petals, semi-erect, double petals, rose red. Venus: The flowers are solitary, crimson, and the calyx is iron-black with hairs on it. The flowering period is as long as 4 months, and it is relatively cold-resistant. Pink: the leaves are narrow and pale, the flowers are pink, and the flowering period is early and long, which can last from 1 1 to April of the following year, and it is relatively cold-resistant. Four-sided brocade: the flowers are red, the petals are scroll-shaped, and there are four groups of * * *, hence the name four-sided brocade.
Camellia are planted in open spaces all over the south of the Yangtze River. It can be propagated by sowing, cutting and grafting. Mostly used to beautify the scenic spots on hillsides and hills, and planted on the north side of other evergreen trees or under the forest edge. The flowering period is mostly between/kloc-0 and-3 months, and potted plants are used all over the north.
Camellia planted by families in the north are mostly potted seedlings in Jiangsu, Zhejiang, Shanghai, Fujian and Guangdong. When planting flowers in the south and flowers in the north, we must conform to nature and create suitable environmental conditions.
Camellia is a warm temperate tree species. Sex likes the semi-cloudy environment with mild, humid and refreshing climate, and is most afraid of the strong wind and scorching sun in the north. Although late autumn is cold-resistant, it can't resist strong winds and dry weather. /kloc-pay attention to the frost in October and October, and enter the room when the temperature is close to 5℃ at night. Put it in a bright place, but when the temperature suddenly rises, open the doors and windows to ventilate and cool down. Otherwise, if the room temperature is kept above 25℃ and it is stuffy and stuffy, the leaves will turn yellow or even the leaves and buds will fall off within 2 ~ 3 days. When the boundary temperature drops and the indoor temperature rises to about 15℃, it can bloom in early spring.
The northern winter is long, dry and cold, so camellia needs to be kept indoors for more than half a year. Generally, the air in the living room is dry and there is often smoke pollution, which is not conducive to the growth of flowers. Sometimes cold air attacks from the cracks in the doors and windows, the doors and windows of the living room are closed from time to time, and the cold air blows straight, and it is hot and cold, which is more likely to cause the branches and leaves to wither and fall off. According to local conditions, lead wire can be used as a frame to make a film curtain cover, which can keep warm and moisturize, and also prevent smoke pollution.
Camellia belongs to fleshy and deep-rooted flowers and trees. Before going out in spring, we should change the soil and spray the medicine every 2 ~ 3 years. The flowerpot should be deep, and the soil should be rich in humus, loose, fertile and highly permeable acidic culture soil (Ph0.5-0.6), and the water quality is slightly acidic. Camellia potted with local pond mud was first introduced from Fujian and Guangdong, and it takes up to one year to change the soil in the north. After Tomb-Sweeping Day in April, choose a half-cloudy and windless sunrise room according to the weather conditions. Put it in the shade of the courtyard or under the diffuse light of the balcony to gradually adapt to the outdoor environment. Camellia is moist and afraid of waterlogging. Should be properly watered, and the soil should always be moist ... >>
Question 7: How to cultivate camellia? The soil planted with camellia should be acidic and require good air permeability. Watering should be both wet and dry. When it is dry, water it and pour it thoroughly. Usually, the fertilizer can be cooked cakes and compound fertilizers, or 0. 1% urea and 0. 1% potassium dihydrogen phosphate, once every 20 days. The optimum growth temperature of camellia is between 15~32℃, and the illumination is stronger than that of rhododendron. It can be shaded in spring, autumn and winter, and it can be shaded by 50% in summer.
Question 8: What cultivation methods are used to grow camellia? Cultivation Techniques of Camellia (1) Brief Introduction
Camellia is a small evergreen tree or shrub of Camellia, commonly known as Camellia. Native to Chinese mainland, Taiwan Province Province, Japan and South Korea; There are more than 90 varieties in the world, but in recent years, after the improvement of European and American varieties, their varieties continue to increase substantially.
Most of the tea leaves are leathery and alternate, with serrated edges. Leaf morphology can be divided into six types: oval, oblong, wide oval, oval, inverted oval and lanceolate.
The shape of leaves can be divided into five types according to the curved shape of leaves: flat, curved, wavy, curved and folded in the middle.
The leaf color and markings of camellia have also changed greatly, mainly "hereditary branch and leaf variety" and "macula caused by viral diseases". Its markings are mostly white or yellow: medium spots, speckles, heavy spots, scanning spots, heavy wheels and edging.
Camellia, mostly petals; The flowering period is 1 1 month to February and March of the following year.
According to the shape of petals, flower patterns can be divided into three categories: one double petal, eight double petal and thousand double petal, and according to the shape of anthers and stamens, they can be divided into four categories: Tangzi type, two-segment type, peony type and lion type.
Color: Camellia has many colors, the main colors are: red, crimson, dark red, fuchsia, vermilion, pink, pink, light pink, yellow, light yellow and so on.
Patterns and camellia patterns are mainly caused by "genetic variation" and "virus pathogen", so if it is caused by "virus pathogen", its white spots will appear or disappear from time to time. Patterns can be divided into nine categories: vertical spots, small stripes, spray spots, ribbed patterns, red cover wheels, white cover wheels, white star spots, white cloud spots, horizontal cloud spots, full color and so on.
(2) type
The so-called camellia, also known as "camellia" or "camellia" or "Toona sinensis" … can be used. However, its varieties and strains are mainly divided into the following three categories:
1. Camellia (L.): Japanese name "Toona sinensis".
Well-known varieties such as: five treasures, white hexagonal, red hexagonal, seven clever, nine songs, eighteen bachelors, white pagoda, Guangdong powder, carp beads, Foding tea and so on.
2. Camellia. L: Also known as "Yunnan Tea" and "Dali Tea".
Well-known varieties such as: carmine, big silvery red, red bowl tea, winter jasmine, peony, purple robe, lotus plumule, hedinghong, poinsettia, brocade robe red, Jing 'an tea, Zhu Baocha and so on.
3. Camellia: Japanese name "Camellia".
Well-known varieties such as: Snow White, Bamei, Lavender, Fuji Peak, Lion Head, asakura, Qifushen, Yumeiyi, Daikin, Sunset, Big Zhu Cup, Golden World, etc.
(3) Breeding technology
1. Cutting propagation method:
Suitable breeding period: April-May after the rainy season, and the soil temperature is about 20-25℃.
The cutting length of camellia is about 10 ~ 15 cm, leaving 2 ~ 3 leaves. The cutting length of "tea plum" is about 6 ~ 10 cm, and 3 ~ 4 leaves are left. You can cut it directly after cutting. If it is left for more than 1 hour, it must be soaked in water for preservation and cut within 40 hours. Cut into the soil about 1/3 ~ 1/2 depth.
Second, the grafting propagation method
Suitable breeding period: February-March or June-July.
The "scion" of camellia can be full branches of last year (that is, biennial), with one bud and one leaf left at each node, and only 1/3 can be left except leaves. "Formwood" must cultivate its own tree potential and grow healthily. Camellia oleifera is often used as profile in Taiwan Province.
Grafting methods commonly used are "cutting", "cutting", "grafting" and "docking".
Third, high-pressure propagation method.
Suitable breeding period: it must be carried out in April-June after the rainy season.
The "high pressure" of camellia can be carried out in the form of "girdling" The ring between epidermis and cambium, which is about 1 ~ 1.5 cm long, was peeled off and wrapped with water moss with water content of about 85%. After 30 ~ 45 days, the roots will germinate. After 20 ~ 30 days, the roots can be cut off and put into the upper pot for cultivation.
Four, sowing and breeding methods
Suitable breeding period: "receiving and sowing method" is from September to165438+1October. The best period of "spring sowing method" is March to April, or May at the latest ... >; & gt
Question 9: How to plant camellia in winter? The focus of winter management is to prevent freezing and protect flower buds. If it is not properly managed, it will affect the flowering quality. In order to make bloom bigger, brighter in color and longer in flowering period, we should do two things well. (1) Anti-freezing and warm camellia is cold-resistant. The author's large pot of camellia has experienced five cold winters under natural conditions, growing vigorously and sprouting all over the branches. However, the temperature of small pot seedlings, weak seedlings, diseased plants and young trees under 4 years old is below 0. C need to prevent freezing and keep warm, so as not to hurt the seedlings. The methods of keeping warm in winter are: < 1 > raising urban camellia in balcony greenhouse. If there is no ground courtyard, you can set up a small greenhouse on the balcony to protect camellia from cold and winter. This kind of small greenhouse is generally made of wooden strips with a slope of 45 degrees, surrounded by plastic film. Cover it with straw mats at night when it is cold to prevent the seedlings from freezing in the greenhouse. < 2 > Garden Greenhouse Camellia lovers in various provinces and cities in the south of the Yangtze River can build greenhouses in their own yards to avoid the cold. This kind of greenhouse is generally made by bending bamboo pieces into arches, inserting them into the soil to form branches and covering them with plastic films. There is no heating in the greenhouse, and the sunlight and heat are used to warm the greenhouse during the day. For freezing weather, cover the greenhouse with grass at night to keep warm. < 3 > For amateurs who grow a small amount of camellia indoors for winter, if housing conditions permit, the temperature will drop to 0. When the temperature is below C, camellia will move into the house for the winter. However, potted flowers should be placed in the sun, and water should be sprayed on the leaves frequently to increase the amount of light and air humidity. (2) bud protection <1> Camellia is dormant or semi-dormant in winter. Due to the low temperature, less water evaporates on the leaves, and the root system absorbs less water, so it is not suitable to water too much, and the basin soil is moderately dry. However, for flowering camellia, the soil in the pot is moist due to physiological needs, but it is necessary to prevent the water in the pot from rotting the roots, resulting in falling flowers and buds. < 2 > Fertilizer Camellia is in a weak physiological activity state in winter, which is characterized by slow growth of leaf buds and flower buds, and requires few nutrients. Generally, it is supplied by the part stored in plants, and a small amount is absorbed from the soil. Therefore, improper fertilization before winter, excessive fertilization, excessive fertilizer solution, application of raw fertilizer, etc. , will lead to the occurrence of bud drop, and even lead to plant death in severe cases. < 3 > In general, it is better to leave 1 strong bud on each strong branch of potted camellia with bud. Excessive nutrient supply often leads to falling buds and flowers, which affects the opening quality of the next year. Camellia planted in the ground has rich nutrition, strong plants, deep and wide root distribution, and can leave more buds, preferably 1 ~ ~ 2 buds per branch. Too many flowers not only have small flowers and short flowering period, but also the plants decline after flowering, which affects the formation and development of new buds. 〈4〉 Indoor camellia overwintering, in order to protect the bud from falling, four preventive measures should be taken: first, to prevent insufficient light, indoor potted camellia should be placed in a sunny place to ensure a certain amount of light; The second is to prevent air circulation, and always open doors and windows to facilitate ventilation; Third, prevent excessive indoor smoke and dust from affecting the breathing movement of camellia, and wash leaves according to specific conditions; Fourth, to prevent the air from being too dry, it is necessary to spray water in time to keep warm.
