Green Begonia Bonsai Cultivation Methods
Green Begonia bonsai, with its unique branch and leaf shapes and year-round ornamental value, has become a popular choice for indoor green plants. As a typical ornamental leaf bonsai, mastering scientific cultivation methods can keep the plant in the best ornamental state. This article will systematically explain the key points of daily maintenance of green Begonia from three dimensions: light management, temperature control, and water and fertilizer supply.
Key Points of Light Management for Green Begonia
Scattered Light Maintenance in Spring and Autumn
During the growing period from March to May and September to November, it is recommended to place it on an east-facing windowsill to receive soft morning light. A shade rate of 30% can be configured with a gauze curtain to maintain the light intensity between 10,000-15,000Lux.
Shading Techniques in Summer
It is necessary to use double-layer shading nets from June to August to avoid scorching the leaves with strong midday sunlight. Adjustments can be made by observing changes in leaf color: yellowing leaves indicate excessive light, and an increased distance between leaves indicates a need for more light.
Full Sunlight Scheme in Winter
From December to February of the following year, it should be moved to a south-facing balcony to ensure at least 4 hours of direct sunlight per day. Using supplemental lights can enhance the effect, and it is recommended to extend the lighting duration to 8 hours.
Green Begonia Temperature Control Standards
Ideal Growth Temperature Range
Maintaining a day-night temperature difference within 5°C is best, with a daytime temperature of 18-22°C and a nighttime temperature of 15-18°C to keep the plant in the best growth state. A temperature above 28°C requires the activation of a misting cooling system.
Overwintering Protection Measures
When the temperature is below 10°C, it should be moved indoors and kept away from radiators. A pot-in-pot method can be used for insulation: the outer pot diameter is 5cm larger, and the middle is filled with a vermiculite insulation layer.
Scientific Scheme for Water and Fertilizer Supply
Precise Watering Strategy
Water thoroughly every 3 days in spring and autumn, mist twice a day in summer, and water a small amount along the pot wall every 10 days in winter. It is recommended to use softened water with an EC value of 0.8-1.2mS/cm.
Fertilizer Ratio Scheme
Apply a liquid fertilizer with an N-P-K ratio of 10-6-8 every 10 days during the growing period, and switch to a 3-12-12 formula during the dormant period. Cake fertilizer needs to be fermented for 60 days and then diluted 50 times before use.
By systematically adjusting light, managing temperature, and supplying water and fertilizer, the green Begonia bonsai can maintain its ornamental value throughout the year. It is recommended to dynamically adjust the maintenance plan based on the actual condition of the plant, with special attention to the transition of the seasons. Regularly rotating the pot ensures even light exposure, and combining leaf surface cleaning can further enhance photosynthetic efficiency.
