Camellia likes warm and humid climate, and it is not suitable for extreme heat and cold. It requires living in acidic soil in semi-cloudy environment, fearing drought and avoiding water accumulation. Therefore, from spring to autumn, we should pay attention to spraying water (not watering) on the leaves every day, and pouring alum fertilizer water or ferrous sulfate solution every 15-20 days. Be careful not to accumulate water in the basin soil when watering at ordinary times. It is enough to water once every 3-5 days in winter. Camellia prefers shading to top shading, so it is better to shade from the side. It likes warmth and is afraid of cold, so it is necessary to move the basin indoors and put it in a sunny place before the cold dew. At the same time, we should pay attention to the prevention and control of the harm of red spiders, scale insects, anthrax, soot disease and so on. Once found, timely prevention and control. I hope my answer will satisfy you!
How often should camellia be watered?
Watering should be done at the alternation of dry and wet. When it is dry, water it thoroughly, but be careful not to overdo it.
How to fertilize and water camellia?
Camellia likes warm and humid climate, likes to avoid the scorching sun, likes semi-cloudy scattered light, and is also resistant to shade.
Camellia is an evergreen shrub or small tree. Like warm climate, the suitable growth temperature is 18 ~ 25℃, and the initial flowering period is 2℃. Slightly cold-tolerant, general varieties can tolerate-10℃ low temperature and heat, but the growth above 36℃ is inhibited. Like high air humidity, avoid drying, and grow in areas with annual precipitation 1200mm or more. I like fertile and loose slightly acidic soil, and the PH value is preferably 5.5 ~ 6.5. There are bamboo shoots and buds twice a year. The first time is spring shoots, summer shoots in March-April, and summer shoots in July-September. The flowering period is long, most varieties are 1 ~ 2 months, and the single flower flowering period is usually 7 ~ 15 days. The flowering period is from February to March.
No excessive fertilization, no concentrated fertilizer. This is the characteristic that camellia doesn't like concentrated fertilizer, otherwise it will damage the root system and reduce the number of flowers. It is best to use organic fertilizer as the base fertilizer of Camellia oleifera, such as fermented chicken and duck manure and animal organs, bean cake, fish bone powder and so on. These organic fertilizers have comprehensive components such as nitrogen, phosphorus and potassium, and have long fertilizer efficiency. When it is applied, it can be dried in the sun, ground into powder, mixed with 5-6 times of dry soil first, and then withdrawn from 2-3 cm away from the roots of plants when the soil is turned over.
How much water does camellia usually water every day?
3. Water fertilization 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 the rice washing water for 2 days to volatilize the chlorine in the water, and then add an appropriate amount of ferrous sulfate (about 0.5% of the 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. 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.
How often do camellias usually water in spring?
Look at the dry and wet, look at some dry and white soil, then water it to see the dry and thoroughly, that is, look at the water oozing from the bottom of the basin to see the wet. There is no such thing as big water and small water.
How many days does camellia water?
Camellia, also known as Camellia, belongs to Camellia of Theaceae. Camellia is rich, dignified and elegant, and it is one of the top ten traditional famous flowers in China. It is also one of the world famous flowers. Camellia originated in China. At the beginning of the 7th century, Japanese introduced camellia from China, and at the beginning of the 5th century,/kloc-introduced a large number of camellia varieties from China. Camellia from China was first introduced to Britain in 1739, and then to Europe and America. So far, the United States, Britain, Japan, Australia and Italy have developed rapidly in the breeding, reproduction and production of camellia, and have entered the stage of industrial production, and interspecific and interspecific hybrids and new varieties are constantly on the market. China has a long history of planting camellia. Camellia has been planted since the Southern Dynasties. Camellia was cultivated as a precious flower in the Tang Dynasty. By the Song Dynasty, it was very popular to grow camellias. Camellia from Wenzhou was introduced to Hangzhou in the Southern Song Dynasty and developed rapidly. The History of Flowers in Ming Dynasty described and classified the varieties of camellia. In the Qing Dynasty, camellia was cultivated more vigorously, and varieties of camellia came out continuously. Since 1949, the cultivation level of camellia in China has been improved to some extent, and the variety selection has developed. At present, there are more than 300 camellia varieties in China. Zhejiang, Fujian and Jiangsu have started mass production. At present, it has become the main potted ornamental flowers and trees in winter in the flower market. Morphological characteristics and varieties: Camellia is an evergreen broad-leaved shrub. Leaves alternate, leathery, oval, serrated, dark green. Flowers are solitary or 2-3 flowers are inserted at the top of branches or between leaf axils. Single or semi-double flowers. Double valve. Common varieties are single petal dawn, wrinkled flower and pure white; Golden light, white flowers, pink lines and fine spots; Big flower with golden heart and big red flower with a diameter of 6-7 cm; Semidouble Sailuoyang, with red flowers and white spots; Large pine nuts with crimson flowers; Drunk Yang Fei, with pink flowers; Star peach peony, pink flowers. The double petals are white Zhu Bao with pure white flowers; Red hibiscus, oleander red; Flower hibiscus, white flowers and red lines; Flower pearls, pink with irregular red stripes; Five cranes hold the ball, and the flowers are red; Flower Buddha tripod, big red flowers, a small amount of white spots; Bachelor of Red Eighteen with red flowers; Red lead, the flowers are big red; Flower crane feathers, reddish flowers with white spots. Biological characteristics: Camellia is native to China. I like warm, humid and semi-cloudy environment. Fear of high temperature, avoid the scorching sun. The optimum growth temperature of camellia is 18-25℃, 13- 18℃ from March to September, and 10- 13℃ from September to next March. Germination begins when the temperature is above 12℃, and stops when the temperature is above 30℃. The initial flowering temperature is 2℃, and the suitable flowering temperature is 10-20℃. Cold-tolerant varieties of camellia can tolerate-10℃ in a short time, while common varieties can tolerate -3-4℃. When the temperature exceeds 35℃ in summer, blade burns will occur. Camellia is suitable for an environment with sufficient water and humid air, and should not be dried. In hot and dry summer and autumn, water or spray water in time, and the relative humidity of air should be 70%-80%. Pay attention to drainage in rainy season to avoid root waterlogging and rot. Camellia is a semi-negative plant, which is suitable for growing in scattered light and afraid of direct sunlight, so seedlings need shade. However, long-term cloudy days are unfavorable to the growth of camellia, with thin leaves and few flowers, which affects the ornamental value. Adult plants need more light to promote the formation and flowering of flower buds. Open field cultivation, deep and loose soil layer, good drainage, pH 5-6, and alkaline soil is not suitable for camellia growth. Potted soil is fertile, loose and slightly acidic loam or humus. Propagation method: common cutting, grafting, layering, sowing and tissue culture propagation. Cutting propagation: the most suitable time is around the middle of June and the end of August. Semi-mature branches with abundant external tissues, complete leaves and full leaf buds were selected as cuttings, with a length of 8- 10 cm and two leaves at the top. When cutting, try to take some old branches at the base, and it is easy to form callus and take root quickly after cutting. The cuttings were cut in the morning, and they should be inserted with the cuttings, and the matrix should be about 3 cm. When cutting, ask the leaves to meet each other, and then press them with your fingers. It is best to insert it shallowly, so that it is breathable and heals quickly. The bed should be shaded, sprayed with leaves every day, kept moist, maintained at 20-25℃, began to heal about 3 weeks after insertion, and took root after 6 weeks. When the roots grow to 3-4 cm, transplant them to the upper pot. Soaking the base of cuttings with 0.4%-0.5% indolebutyric acid solution for 2-5 seconds can obviously promote rooting. Grafting propagation: it is often used for cutting varieties with difficulty in rooting or few propagation materials. The survival rate of grafting is the highest when the new buds are semi-qualitative in May-June, and the new buds germinate quickly after grafting. Camellia oleifera is the main rootstock, which was harvested in June+10 in 5438, stored in sand in winter and harvested in April of the following year ...
Camellia only blooms in winter. Why water less in winter? How to properly water?
If the temperature is too low, if there is too much water, it will rot and die easily.
Don't water plants too much in winter, whether they bloom or not. The temperature is already low, and water evaporation will take away excess heat, which is easy to cause frostbite and necrosis of plant roots. Plants can't live without a good root system.
