How to hydroponically culture Ginseng Ficus
Hydroponically cultured Ginseng Ficus is loved for its unique root and stem shapes, but it requires special techniques for care. Through scientific management of water quality and adjustment of the growth environment, the Ficus tree can maintain vigorous vitality when transitioning from soil to hydroponics. This article will provide a detailed analysis of the complete process of hydroponic care, focusing on key aspects such as water quality selection, water-changing cycles, and nutrient supplementation.
Core Care Elements for Hydroponic Ginseng Ficus
Light Environment Adjustment
As a tropical plant, Ginseng Ficus requires 4-6 hours of scattered light daily. Avoid direct sunlight at noon in the summer and allow full sun in the winter. It is recommended to use frosted glass bottles with 60% light transmission for the hydroponic container, which can meet the lighting needs and prevent excessive algae growth.
Water Quality Management Standards
Initially, use pure water with a TDS value less than 50, and after the transition period, use tap water that has been exposed to air for 2 days. The water temperature should be maintained between 18-25°C, with a difference of no more than ±3°C from the room temperature. The dissolved oxygen concentration in the water is recommended to be maintained at 5mg/L or higher, which can be achieved through an aeration pump or regular water changes.
Step-by-Step Guide for Water Replacement
Initial Hydroponic Phase (1-7 Days)
Implement an intensive water replacement strategy in the first 7 days, changing all the nutrient solution every 48 hours. Add 2ml of water stabilizer each time and use an EC pen to measure the electrical conductivity of the water, which should be controlled within 800μS/cm.
Adaptation Period (8-14 Days)
Adjust the water replacement frequency to 3 times per week, focusing on observing the secretion of root mucilage. If transparent gel-like substances appear, immediately clean the roots and disinfect them with a 0.1% potassium permanganate solution.
Stable Phase (After 15 Days)
In the stable care phase, replace the water once a week and simultaneously: 1. Trim the aging roots (retain 2/3 of healthy roots) 2. Clean the inner walls of the container 3. Supplement 5ml of nutrient solution with a nitrogen-phosphorus-potassium ratio of 1:1:1.
Key Care Precautions
Do not use any nutrients in the first month of transitioning to hydroponics. Only add nutrients after the new water roots exceed 3cm in length. It is recommended to use a special nutrient solution for orchids with a pH value of 6.0-6.5, along with weekly foliar application of chelated iron fertilizer. When the water temperature exceeds 28°C, wrap the container with insulating material to prevent root damage from high temperatures.
By precisely controlling light intensity, water quality parameters, and nutrient supply, hydroponic Ginseng Ficus can maintain an ornamental lifespan of 5-8 years. Regularly check the root condition and promptly address algae growth issues to ensure this 'water potted landscape' continues to display its unique artistic charm.
