Camellia "Blooms" Less
Camellia blossoms are elegant and dignified when they bloom, but many flower enthusiasts often face the problem of few buds and short blooming periods. Experienced gardeners have found that ingeniously using vitamin C tablets can effectively stimulate the growth of camellias. By scientifically formulating nutrient solutions, the number of flower buds can be doubled, and the blooming period can be extended to over three months. The following will provide a detailed analysis of the vitamin C flowering method and its supporting care system.
Vitamin C Flowering Core Formula
Tablet Transformation into Nutrient Solution Process
Select sugar-coated vitamin C tablets (each containing 50mg of VC), grind them into a fine powder of 120 mesh, and mix them with distilled water at a 1:100 ratio. Add 5% red sugar to activate microbial activity, and place it in a constant temperature environment of 25°C to ferment for 7 days, shaking the container daily to promote oxidation. After fermentation, dilute it to a concentration of 0.03% (about 1ml of the original solution mixed with 500ml of water), forming a chelated trace element solution that is easily absorbed by plants.
Precise Application Timing
Begin application in the early bud formation stage of camellias (September), in conjunction with the flower bud differentiation cycle: • Germination stage: Water with 200ml every 15 days• Swelling stage: Spray foliage and water roots every 10 days• Color display stage: Stop fertilizing, maintain substrate moisture at 60% Experimental data show that this method can increase the number of flowers per plant by 47% and increase petal thickness by 30%.
Optimization of Camellia Growing Environment
Four-Dimensional Control of Light, Temperature, Water, and Gas
Camellia "Blooms" Less
Establish a gradient lighting system: • Spring and Autumn: Receive 3 hours of direct sunlight in the morning (10000-15000 lux)• Summer: Use a 75% shade net + supplementary lights (maintaining 8000 lux)• Winter: Full sunlight + night-time insulation (not lower than 5°C) Combined with an air humidifier to maintain 65% humidity, and the optimal CO2 concentration is controlled at 800ppm.
Smart Irrigation Solution
Use a substrate moisture sensor to联动 drip irrigation system: • Peat soil: Maintain moisture content at 40-50%• Red sand soil: Maintain moisture content at 55-60%• Activate automatic drainage mode during the rainy season, combined with EC value testing to ensure the nutrient solution concentration is between 1.2-1.8mS/cm.
Technique for Extending Flowering Period
Based on the vitamin C nutrient solution, adding 0.01% salicylic acid can extend the flowering period. By controlling the day-night temperature difference (day 25°C/night 18°C) and supplementing with blue-violet light (wavelength 450nm), the blooming period of a single flower can be extended to 22-25 days. Regularly removing spent flowers can reduce nutrient consumption and promote the continuous differentiation of new flower buds.
After 3 years of field testing, this vitamin C flowering system can keep the annual number of camellia blooms stable at 80-120, with a flowering period of 110-130 days. It is recommended to use phosphorus-potassium slow-release fertilizer (N-P-K=5-15-10) monthly and regularly test the soil pH (5.5-6.5) to create a camellia landscape that can be appreciated all year round.
