Remember these 5 points
As the most ornamental woody flower in winter, camellia often takes half a year from bud to bloom. The long maintenance period will cause the buds to dry up and fall off. Only by mastering the correct maintenance techniques can the camellia bloom on time. This article reveals five core maintenance points from the dimensions of light, temperature, water and fertilizer. Core points of camellia winter maintenance 1. Light management: You have the knack for precise control. Winter sunshine is mild. It is recommended to maintain direct light for 6-8 hours every day. When it is found that the flower bud is blocked by the upper leaves, the blocking leaves can be removed appropriately. However, attention should be paid to retaining the petiole to avoid direct damage to the bud point. The southeast facing bay window is an ideal location. 2. Temperature control: In the golden range, keep in mind that 5-15℃ is the best temperature range. Attention should be paid to the northern region: heat sources should be avoided by more than 2 meters in heating rooms, and plastic bags should be put on when the cold wave approaches. Controlling the temperature difference between day and night within 8℃ can effectively prevent buds falling. 3. Water regulation: Dry and wet cycles are the key, remember these 5 points
Use the "see dry, see wet" watering method: when the surface layer of 3 cm of soil turns white, pour it thoroughly until the bottom of the basin seeps water. It is recommended to use acidified water with a pH of 5.5-6.5 (2ml of lemon juice per liter of water) and apply ferrous sulfate solution once a month. 4. Humidity maintenance: In addition to using a humidifier, you can try the triple moisturizing plan: ① cobblestone water tray method ② hanging wet towels ③ group planting to increase humidity. Be careful to avoid spraying water directly on the flower buds, otherwise it may cause mildew. 5. Ventilation skills: Scientific ventilation and disease prevention are used to open windows for ventilation from 11:00 to 14:00 every day, and circulation fans are used to promote air flow. In case of smog, an internal circulation purification system can be used to keep the air fresh while filtering harmful particles. Key operations during the flower bud expansion period 1.
