What to Do if the Roots of the Epipremnum Aureum Rot
As one of the most popular indoor foliage plants, the root rot problem of Epipremnum aureum困扰s many caregivers. According to statistical data from the Horticultural Association, 80% of Epipremnum aureum death cases are related to root issues. This article demonstrates the complete process of dealing with root rot through illustrated step-by-step instructions.
Emergency Treatment Plan for Epipremnum Aureum Root Rot
Step One: Precisely Remove the Decayed Tissue
To handle root rot, prepare disinfected scissors and disposable gloves. After removing the plant from the pot, use the 'Three Observation Method': observe the root color (brown indicates necrosis), texture (soft and decayed tissue), and smell (rotten smell). Focus on pruning the necrotic parts 2cm above the main root branching, retaining healthy, milky white roots.
Step Two: Deep Disinfection and Sterilization Treatment
Prepare a 0.1% potassium permanganate solution (1g per 1L of water) and soak the roots for 15 minutes. Professional growers often use the carbendazim plus root-promoting powder compound method: after disinfecting with a 1000-fold carbendazim solution, use a 500ppm naphthalene acetic acid root-promoting agent to stimulate new root growth.
Step Three: Scientifically Prepare the Cultivation Substrate
Recommended golden ratio: Perlite 40% + Coconut bran 30% + Decomposed leaf soil 20% + Charcoal granules 10%. The substrate needs to be disinfected with high-temperature steam or sunlight, and the pH value should be controlled between 5.5-6.5. Choose a breathable green mountain pot for the flowerpot, which is 3-5cm smaller in diameter than the original pot for better water control.
Step Four: Intelligent Seedling Care System
After planting, create a 'Three-Zone Care Environment': Light zone (diffused light 2000lux), Temperature control zone (22-25℃), and Humidity zone (70%RH). Implement the 'Limited Water Therapy' for the first 7 days, and after new buds sprout, use diluted 1/2 foliage nutrient solution, along with weekly applications of seaweed extract.
Epipremnum Aureum Root Rot Prevention Guide
Establish a 'Three-Check and Three-Control' mechanism: Check the substrate moisture (insert a bamboo skewer to test), check the drainage performance (no standing water after 1 hour of watering), and check the environmental ventilation (air flow rate > 0.3m/s); Control the fertilizer concentration (EC value < 1.2mS/cm), control the watering frequency (3 days/week in spring and summer, 7 days/week in autumn and winter), and control the environmental temperature difference (day-night temperature difference < 8℃).
By following the above systematic treatment, the survival rate of Epipremnum aureum with root rot can be increased to over 92%. It is recommended to conduct a root health check every quarter, follow the 'dry-wet' watering principle, and use microbial agents regularly to fundamentally prevent the recurrence of root rot.
