How to Solve the Odor Problem of Epipremnum aureum
Epipremnum aureum, as a widely popular indoor green plant, occasionally has an odor problem that often troubles its caretakers. This article systematically analyzes the three main causes of the smell from Epipremnum aureum and provides verified solutions to help you quickly restore the plant's health.
Handling Waterlogging and Root Rot in Epipremnum aureum
Diagnosis of Waterlogging Damage
60% of the odor from Epipremnum aureum originates from waterlogging in the roots. When the soil moisture exceeds 80%, the roots enter a hypoxic state. At this point, a visible film of water can be seen on the soil surface, and the leaves show brown spots.
Scientific Soil Loosening Techniques
Use the three-point positioning soil loosening method: insert bamboo sticks along the pot wall in a triangular shape, reaching 2/3 of the pot height, and combine with tilting the pot 30 degrees to promote drainage. In severe cases of waterlogging, replace the substrate with a new mixture of peat soil: perlite = 3:1.
Remedy for Over-fertilization in Epipremnum aureum
Standards for Identifying Fertilizer Damage
When the leaf edges show burning and are accompanied by an ammonia smell, it indicates that the nitrogen fertilizer concentration is excessive. In winter, the fertilizing interval should be extended to 45 days, and the amount should be controlled at 1/3 of the growing season.
Emergency Response Process
Upon discovering fertilizer damage, immediately perform a three-level rinse: water the plant with room temperature water continuously for three times, with a 15-minute interval between each. Combine with the use of an activated carbon adsorption layer, laying a 1cm thick layer of bamboo charcoal particles at the bottom of the pot.
Epipremnum aureum Ventilation and Maintenance Plan
Optimization of Environmental Parameters
Keep the air circulation index above 2m/s, and control the relative humidity between 55-65%. It is recommended to use a hygrothermometer for monitoring, and in enclosed spaces, a circulating fan can be set up to achieve air convection.
Seasonal Adjustment Strategies
In summer, use the morning and evening double-time ventilation method (7-9 am/6-8 pm), and in winter, implement an intermittent ventilation mode (open the window for 10 minutes every 2 hours) to avoid abrupt temperature changes.
By scientifically controlling water, precision fertilizing, and intelligent ventilation, not only can the odor of Epipremnum aureum be eliminated, but the plant's resistance can also be enhanced. It is recommended to conduct a root health check every month, use pH test paper to monitor soil acidity and alkalinity, and establish a maintenance log to record key parameters, fundamentally preventing the recurrence of odors.
