How to make camellias bloom earlier and techniques for extending the blooming period of camellias.

How to Make Camellias Bloom Early

As one of the top ten famous traditional Chinese flowers, camellias are deeply loved by gardening enthusiasts for their brilliant and colorful blooms. Many flower friends are curious about how to control the blooming cycle of camellias, allowing them to bloom early in spring and maintain their full beauty for an extended period. This article will揭秘 the secrets of camellia blooming control from a professional care perspective.

Three Core Techniques for Promoting Camellia Blooms

Accurate Hormonal Regulation Method

From late July to mid-August, select robust buds with a diameter of 1.5-2 centimeters, dip medical degreased cotton in a 200ppm gibberellin solution, and apply to the base of the buds at 9 a.m. every morning. Avoid the leaves during the operation, repeat after 3 consecutive treatments with a 7-day interval, which can significantly promote bud differentiation.

Temperature Gradient Control Technique

Use smart temperature control equipment to create a day-night temperature difference: maintain 18-22°C during the day and 12-15°C at night, combined with 75% air humidity, to promote blooming about 30 days earlier. Special note: tropical varieties like Yunnan camellias require a higher temperature gradient.

Differential Management Based on Variety Differences

Early blooming varieties like "Eighteen Scholars" should start treatment from the beginning of the autumnal equinox, while late blooming varieties like "Chidan" should be handled after the end of heat. Grafted seedlings are more responsive than seedlings, and five-year-old robust plants show the best blooming results.

Four-Dimensional Camellia Flower Extension Care System

Scientific Watering Plan

Use the "dry-wet" irrigation method with acidified water (pH 5.5-6.5, adding 0.5g of citric acid per liter). During the blooming period, water every 3 days using the immersion method to maintain a substrate humidity of 40-50%.

Photoperiod Regulation

Ensure 4 hours of direct sunlight and 6 hours of scattered light during the full bloom period, adjust the light intensity to 15000-20000Lux with a shading net. Especially during the noon, avoid strong light that may burn the petals.

Nutrition Supply Strategy

Alternately use potassium dihydrogen phosphate (1:1000) and decomposed fish intestine water (1:50), spray on the leaves and water the roots weekly. During the budding stage, apply borax solution (0.2% concentration) to enhance flower tenderness.

Environmental Collaborative Management

Maintain good air circulation but avoid strong winds, use a humidifier to keep the relative humidity stable at 60-70%. Regularly rotate the flower pots to ensure even light exposure, promptly remove withered flowers to reduce nutrient consumption.

Through the above systematic care measures, camellias can bloom early for the New Year and Spring Festival, and the single flower period can last up to 15-20 days. It is recommended to adjust the plan flexibly based on the plant's growth condition, regularly test the soil EC value (controlled at 1.2-1.8mS/cm) and pH, to make camellias bloom even more brilliantly and enduringly.
