Second, fertilizer and water management. After entering the winter in the north, Camellia has to move into the greenhouse to protect against the cold. At this time, the flower buds are very large and will gradually open after the spring. In order to reduce the budding buds, the flowers should be large and bright. Before the opening, apply a fertilizer for about 10 days until the buds are dewy. However, the fertilizer should be thin and light, and it should be dominated by phosphorus-containing organic fertilizers. For plants whose flowers cannot be open at the same time, after the previous batch of flowers, when the flowers are not displayed at the back, supplement the nutrients in time, which ensures that the flowers behind are well opened and fully opened, but do not apply fertilizer when flowering.
Low winter temperatures and low water consumption. Observe carefully to ensure that the basin soil is properly dried and wet, with 60% to 70% of the glutinous Rice is declared. Of course, the water volume during the flowering period can be slightly larger. Watering should also be carried out before and after noon.
Third, cold. Although Camellia has a certain ability to withstand cold, but in the north of the Yangtze River Valley, there are not many varieties that can be exposed to winter, so it is still mainly to appreciate. At the end of October each year, the camellia should be transplanted into a greenhouse or plastic shed to prevent winter and overwintering. Don't put it on the air outlet after entering the room so as not to cause frozen buds due to cold wind. Before and after noon on a windless day, open the window and change the air, and when the room is dry, spray water and humidify the plants and the ground. The temperature difference between day and night during the winter can not be too large, otherwise it will lead to normal opening of the bud. In particular, plastic greenhouses, the temperature within the shed can reach 30Â°C. At this time, it is necessary to pay attention to opening ventilation vents to cool down and close the ventilation holes at about 4 pm.
Fourth, fixed position. Overwintering plants should be given good light, flowering plants do not often move, otherwise it will cause the tree photosensitive dislocation or discomfort to the environment, resulting in budding buds and buds. If you really need to move, you should pay attention to environmental differences can not be too large, the orientation of the plant after the move should be consistent with the original. It should also be noted that the condensate in the greenhouse is often dripping on the flower buds, and it can also cause the buds to fail to open and rust, as long as they are discovered in time and moved a little to solve the problem.
