Camellia has buds, why don't they bloom?
Camellia blooming is a grand sight that every flower friend looks forward to, but the delay in opening the buds is often confusing. This article will systematically analyze the key factors that affect the opening of camellia from environmental adaptation to maintenance details, and provide scientific flower promotion solutions to help you solve the problem of camellia "blooming". Four major reasons for the stagnation of camellia buds 1. Environmental mutations cause the phenomenon of "stiff buds" in newly purchased camellia during the dormant period, mostly due to environmental mutations. Plants need 15-30 days to adapt, which should be maintained during this period: ·Scattered light environment (avoid direct sunlight)·Air humidity of more than 60%(can be combined with a humidification tray)·Suspension of fertilization (reduced root absorption capacity)·Stabilize the temperature at 18-22℃ (avoid direct air conditioning) 2. Nutritional imbalance hinders the development of flower buds requires a specific nutrient ratio: ·Budding period: Apply potassium dihydrogen phosphate (concentration 0.1%) every week·Budding techniques: Keep 2-3 full flower buds per branch·Soil improvement: Regularly add decomposed pine needles to adjust pH (pH 5.5 -6.5)·Trace element supplementation: spray ferric chelate solution every month 3. Improper temperature control Temperature management needs to be controlled in stages: ·Vernalization stage (November-January): Keep a low temperature of 8-12 ° C for 40 days·Flower-promoting stage: Gradually increase the temperature to 15-25 ° C·Temperature difference between day and night: Maintain 5-8 ° C The temperature difference is more favorable for flowering·Anti-freezing measures: If the temperature is lower than 5 ° C, you need to enter the house for maintenance 4. Light management error reasonable lighting scheme: ·Daily guarantee 4-6 hours of direct light·Use sunshade net to filter midday strong light (summer 50% shading rate)·Regular turn pot to ensure uniform light·Supplementary light scheme: rainy days can be used plant fill light (2000-3000lux) After mastering these four maintenance points, more than 80% of camellia flowers can bloom as scheduled. It is recommended to adjust the maintenance strategy based on the actual state of the plant and regularly observe the development of flower buds. Usually, healthy flower buds will gradually expand and open within 1-2 weeks under appropriate conditions.
