The Hydroponic Method for Banyan Trees
Hydroponic banyan trees have become a new favorite in modern households due to their clean and elegant appearance. Compared to traditional soil cultivation, hydroponics not only allows clear observation of root growth but also effectively prevents soil-borne diseases and pests. This article will systematically explain the complete cultivation process of hydroponic banyan trees, from selecting seedlings to daily maintenance.
Key Preparation Steps for Hydroponics
Selection of Seedlings and Container Configuration
Choose straight-trunked, evenly-branched young banyan seedlings with bright green leaves free of burnt edges. It is recommended to use a transparent glass container with a diameter of 10cm and a height of 30cm, which is convenient for observing roots and enhances visual appeal. When using a cola bottle to make a planting frame, trim the edges to avoid injuring the roots.
Plant Handling Standards
When potting, use the tapping method to break the original pot and then soak the intact soil ball in water for 2 hours. Use a soft-bristle brush to clean the attached soil layer by layer, focusing on pruning blackened and rotten roots until healthy white tissue is exposed. After disinfection, it is recommended to soak in a rooting hormone solution for 30 minutes, which can increase the success rate of hydroponics by 20%.
Core Techniques for Growing Water Roots
Environmental Control Points
Place the container in a diffused light environment with a temperature of 25-28℃ and maintain an air flow rate of >0.5m/s. Implement a daily water change system for the first two weeks, using tap water that has been standing for 24 hours. When the main roots have grown 3-5cm white water roots, the plant can be transferred to the regular maintenance stage.
Water Level and Water Quality Management
Keep the roots in a 2/3 submerged state and use a TDS pen to monitor water quality, changing water immediately when the value exceeds 300ppm. In summer, supplement evaporated water every 3 days, and in winter, extend it to once a week. Clean the inside of the container with a 3‰ citric acid solution once a month to prevent algae growth.
Building a Nutrient Supply System
Scientific Fertilization Plan
During the growing season from April to October, use a nutrient solution with an EC value of 1.2-1.5mS/cm, and apply 30g of slow-release compound fertilizer monthly. For foliar application, use a mixture of 0.1% potassium dihydrogen phosphate and 0.05% chelated iron, spraying once every 15 days. During the dormant period in winter, use a nutrient solution with an EC value of 0.8mS/cm.
Dealing with Common Issues
Immediately cut off the affected part when root browning occurs and soak in a 0.5% potassium permanganate solution for disinfection. For yellowing leaves, add EDTA-Fe chelated iron fertilizer and increase lighting to 2000-3000lux. Regularly check the stability of the planting frame to prevent plant toppling and damaging new roots.
Through systematic management of the water environment and precise nutritional control, hydroponic banyan trees can be enjoyed all year round. The key is to balance the three elements of water temperature, light, and nutrition, combined with regular water changes and container cleaning, to cultivate a crystal-clear rooted, lush and flourishing ecological artwork.
