How to Prevent Root Rot in Hydroponic Fortune Trees
Hydroponic fortune trees have become a new favorite in homes due to their clean and beautiful appearance, but the issue of root rot has troubled many growers. This article systematically analyzes the causes of root rot from five dimensions and provides actionable solutions to ensure the healthy growth of your hydroponic plants.
Scientific Root Pruning Management
Pre-treatment Techniques Before Hydroponics
Select robust branches with a diameter of 2cm or more, use pruning shears sanitized with alcohol, make a 45-degree oblique cut 5cm from the base to increase the water absorption area. Remove all leaves below the bottle mouth to prevent decaying leaves from polluting the water.
Periodic Maintenance Pruning
Check the root condition monthly, retain 3-5cm of woody old roots. When new hydroponic roots exceed 15cm, keep 8-10cm of the main root and cut it short to stimulate the development of capillary roots. After pruning, soak in a 0.1% potassium permanganate solution for 15 minutes to sterilize.
Precise Water Level Control Strategy
Initial Planting Water Level
Maintain the water level 0.5cm above the cut during the initial hydroponic stage, use a water level ruler for regular monitoring. It is recommended to use a transparent container for easy observation, and the water surface should have more than 1/3 of the container's mouth area in contact with air.
Water Level Adjustment in the Mature Stage
When new hydroponic roots grow to 3cm, gradually lower the water level to 1/3 of the roots. In summer, when evaporation is fast, supplement water through atomizing spray to avoid directly adding water, which can cause a sudden drop in dissolved oxygen.
Intelligent Environmental Control Solutions
Light Management System
Set 4-6 hours of scattered light daily, maintaining illuminance at 5000-8000lux. Use shade nets to adjust strong light, and position LED supplemental lights 40cm away from the plants to ensure a day-night temperature difference of ≤5℃.
Temperature and Humidity Balance
Keep the water temperature between 18-25°C and the air humidity between 60-75%. Use a恒温 pad in winter and a layer of ceramic stones for insulation in summer to prevent sudden temperature changes that can cause root stress.

System Cleaning and Maintenance Procedures
Water Replacement Cycle Standard
Change 1/2 of the water every 5 days in spring and summer, combined with seaweed acid nutrient solution (EC value 1.2-1.6mS/cm). Extend to 10-15 days in autumn and winter, using an activated carbon filtration system to maintain water stability.
Algae Biocontrol
Add 0.02% hydrogen peroxide to inhibit algae growth, or release 3-5 apple snails for biological control. Regularly clean the inner walls of the container with a soft brush to prevent the formation of a biofilm.
Emergency Root Rot Treatment Process
Disease Identification and Diagnosis
Observe the color change of the roots: healthy roots are milky white, and diseased roots are dark brown with mucus. Mild root rot (＜30%) can be rescued, while severe rot requires re-cutting.
Root Regeneration Operation
Completely remove the diseased tissue and soak the base in naphthylacetic acid (100mg/L) for 30 minutes. Transition to a perlite matrix for intermediate care until new roots emerge, then return to the hydroponic system.
Through the协同 management of regular pruning, intelligent water control, environmental optimization, system cleaning, and timely treatment in five dimensions, the risk of root rot can be effectively reduced by over 90%. It is recommended to establish a maintenance log, recording key data such as water replacement time and root condition, to achieve precise care. Pairing with tools like EC meters and illuminance meters makes hydroponic fortune tree care more scientific.
