As a star candidate for indoor greenery, the Epipremnum aureum is loved for its strong vitality and air purification function. However, root rot issues frequently occur during maintenance, especially with beginners who often fall into the trap of overwatering. This article systematically analyzes the methods for identifying root rot in Epipremnum aureum and provides a scientific treatment plan to help you revive the damaged plant.
A Four-Step Rescue Guide for Root Rot in Epipremnum Aureum
Step One: Stop Watering Immediately
Once root rot is detected, stop watering immediately and move the plant to a well-ventilated area. Check the moisture of the potting soil with a bamboo skewer, and if it brings out wet soil, let the roots dry for 2-3 days until the topsoil is completely dry.
Step Two: Precise Root Treatment
After removing the plant from the pot, shake off the old soil and cut off the black,腐烂 roots with a sterilized pair of scissors, leaving the healthy white roots. Soak in a potassium permanganate solution for 20 minutes, then apply wood ash to accelerate wound healing.
Step Three: Scientific Potting and Soil Replacement
Prepare a mix of 4:3:3 of perlite, decomposed leaf soil, and pine bark as the growing medium, and place a 3cm layer of ceramic stones at the bottom of the pot for drainage. After potting, press the soil down to keep the plant upright and stable.
Step Four: Fine-Tuning the Environment
During the initial maintenance period, maintain a constant temperature of 25°C and use grow lights to provide 5000lux of scattered light. Keep the air humidity between 60%-70%, and use a tray to increase humidity to prevent leaf dehydration.
Three Early Warning Signs of Root Rot in Epipremnum Aureum
Abnormal Root Changes
Healthy roots are white and fibrous, while rotten roots turn black and soft, easily break when pulled, and secrete a sticky fluid.
Abnormal Changes in Growing Medium
Hydroponic solution becomes cloudy with fluffy substances, soil-based medium hardens and turns white, with green algae or mold appearing on the surface.
Overall Plant Symptoms

By regularly checking the root condition, controlling the watering frequency (5-7 days/week in spring and autumn, 10-15 days/week in winter), and using a bamboo breathable pot, you can effectively prevent the recurrence of root rot. A plant that has been successfully treated will sprout new roots in about 20 days, at which point you can apply a diluted HB101 vitality formula (2000 times) to promote recovery. Remember, the secret to maintaining Epipremnum aureum is the scientific management of 'keeping the roots dry and the leaves moist.'
