What to Do When the Roots of the Epipremnum Aureum Rot in Winter
In the cold winter season, the rotting of the roots of Epipremnum aureum becomes a frequent problem that troubles plant enthusiasts. In low-temperature and high-humidity conditions, slow evaporation of water can easily lead to soil accumulation, and if not addressed promptly, it may cause the entire plant to wither. This article will systematically analyze the solutions to the root rot problem of Epipremnum aureum in winter, from root rescue to key points of maintenance.
Three-Step Emergency Root Rescue
Accurate Pruning of Rotten Tissue
When yellowing and wilting of the leaves are observed, stop watering immediately and check the plant by removing it from the pot. Use garden shears sanitized with alcohol to completely remove the black,腐烂 roots, retaining a 0.5cm transition area of healthy roots. Be sure to distinguish between the natural lignification of old roots (yellowish-brown and hard) and pathological rot (black and slimy).
Scientific Formulation of Regeneration Substrate
It is recommended to use a mixed formula of peat soil: perlite: pine bark = 3:1:1, with 5g of bamboo charcoal granules added per liter of soil to enhance breathability. Adding vermiculite in winter can improve the insulation properties of the substrate and prevent secondary frostbite.
Key Points of Environmental Regulation
Smart Watering Strategy
Use the bamboo skewer test: insert a barbeque skewer 2/3 into the potting soil, and after 10 minutes, remove it to observe the moisture. The watering interval in winter should be extended to 15-20 days, and the water temperature should be the same as the room temperature to avoid stimulation from temperature differences.
Stereoscopic Insulation Solution
Build a simple insulation shed: use PVC pipe supports + transparent plastic film, and cover at night to maintain a temperature of 10℃ or higher. Wrap the flower pot with bubble wrap, and place a layer of sawdust as an insulating layer on the ground, forming a three-dimensional protective system.
Through systematic treatment of root repair, substrate improvement, and environmental regulation, the survival rate of Epipremnum aureum can be increased to over 85%. It is recommended to use EM bacteria solution for root watering once a month to enhance the root's resistance to adversity. Preventive maintenance is more important than post-event treatment, and maintaining indoor air circulation in winter is crucial.
