Three Key Elements of Environmental Control
Substrate Selection and Ratio
It is recommended to use a mixed substrate of peat soil: perlite: coarse sand in a ratio of 3:2:5, with a 2cm thick layer of ceramsite at the bottom to enhance drainage. Add bone meal as a base fertilizer every two years when repotting to effectively prevent waterlogging and root rot.
Light and Temperature Regulation Plan
In spring and autumn, ensure 6 hours of direct sunlight, and in summer, provide shade net protection from 11 am to 3 pm. Maintain an environment above 12℃ in winter, which can be achieved with a double-glazed window plus a supplementary light. Keeping the temperature difference within 8℃ can maintain the vivid color of the leaves.
Key Points of Daily Management
Scientific Watering Techniques
Use the immersion method to water every 5 days, with the water level not exceeding 1/3 of the pot height. Set up a rain shelter during the rainy season, and stop watering when the air humidity is over 70%. Wrinkled leaves are a sign of water shortage and should be watered immediately.
Shaping and Pruning Methods
During the growing season, prune dense branches monthly, leaving 2 pairs of leaves at the base to promote new growth. Apply a fungicide powder to the cut ends and avoid watering within 3 days after pruning.
