Why do camellia flower buds fall off
Camellia can always amaze all four people when they bloom, but many flower friends have encountered the dilemma of falling before the buds open. When carefully cared for camellia begins to fall off buds, this not only affects the ornamental value, but also hides a health crisis of the plant. This article will deeply analyze the three key maintenance points and help you solve the problem of camellia flowering maintenance. The deep inducement of camellia buds falling off, the challenge of new environmental adaptation period, newly purchased camellia often produces stress reactions due to sudden environmental changes, and the temperature and humidity fluctuations caused by transportation can reach more than 15℃. It takes 3-6 weeks for the roots to adapt to the new soil environment, and it is normal to continue to fall leaves and buds during this period. It is recommended to keep the original basin soil for maintenance for 1 month, maintain a stable temperature of 18-25℃, and control the air humidity at 60%-70%. The double-edged sword of water management Camellia root system is extremely sensitive to stagnant water. If the soil water content exceeds 70% for three consecutive days, suffocation can be triggered. Within 12 hours after over-watering, the plant will activate a self-protection mechanism and preferentially cut off the nutrient supply to the flower buds. A typical symptom is that the base of the pedicel turns yellow first, and then the whole flower falls off. Four-step scientific maintenance plan root system recovery plan When the pot soil is found to be too wet, immediately take three-step first aid: first, tilt the flowerpot 45 degrees to drain the accumulated water, second, use a bamboo stick to make 20-30 ventilation holes on the soil surface, and finally move the plant to a ventilated place and suspend watering for 3-5 days. Combined with foliar spraying of 0.1% potassium dihydrogen phosphate can enhance the plant's stress resistance. Winter maintenance of the precise water supply formula requires mastering the "three-look" principle: first, the topsoil turns white to 2 cm, second, the weight of the basin body is reduced by 1/3, and third, the leaves droop slightly. It is recommended to use the immersion basin method to replenish water, and the immersion time per time is controlled within 30 seconds to ensure that water penetrates evenly without sedimentation. Nutritional control strategy Special attention should be paid to the ratio of phosphorus and potassium during the bud development period. It is recommended to use a water-soluble fertilizer with a formula of 12-15-30+2MgO, applied once every 10 days. At the same time, supplementing chelated trace elements, especially boron, is crucial for flower bud differentiation and can effectively reduce the occurrence of abnormal flower buds.
Camellia flowering management is a fine science, from environmental regulation to water and fertilizer management. By establishing a stable maintenance system and cooperating with scientific observation and records, camellia will surely be able to bloom all over the trees every year. It is recommended that flower friends check the status of the plants regularly. Prevention in advance is better than remedy afterwards.
