What are the reasons for the root rot of Epipremnum aureum? Complete guide to the prevention and control of Epipremnum aureum root rot.

Why Does Epipremnum aureum Rot and How to Treat ItAs the king of indoor green plants, Epipremnum aureum, with its lush vines, has become a favorite for home decoration. However, the frequent occurrence of root rot during maintenance often causes headaches for growers. This article will systematically analyze the root causes of soil-grown and water-grown Epipremnum aureum root rot and provide operable prevention and treatment solutions to help you cultivate strong and healthy root systems.Deep Causes of Epipremnum Aureum Root RotThree Major Causes of Soil-Grown Root Rot1. Substrate compaction: More than 68% of soil-grown root rot cases are caused by insufficient substrate aeration. Ordinary garden soil without added perlite/river sand forms a dense compacted layer after watering, making it difficult for the roots to breathe as if wrapped in concrete.2. Overwatering: Although Epipremnum aureum prefers moisture, the roots need alternating wet and dry conditions. Continuous waterlogging causes the root hair cell walls to rupture, leading to visible blackening and softening of the roots.Key Factors in Water-Grown Root Rot1. Eutrophication of water: Water that is not changed in time breeds a large number of algae and microorganisms, competing with Epipremnum aureum for dissolved oxygen in the water, leading to root hypoxia and rot.2. Temperature imbalance: Water temperature above 28°C accelerates root metabolism, while water temperature below 12°C in winter causes root dormancy and necrosis.Epipremnum Aureum Root Rot Rescue PlanFour-Step Emergency Treatment for Soil-Grown Plants1. Pot removal and root cleaning: Gently tap the pot wall to remove the plant and rinse with running water until the complete root system is exposed.2. Precise root pruning: Use a pair of scissors disinfected with alcohol to cut off the brown and rotting roots, retaining the healthy white roots.3. Soil improvement: Mix peat soil, perlite, and leaf mold in a 4:3:3 ratio to ensure the substrate is permeable and breathable.4. Water control and maintenance: Water when the top 3 cm of soil is dry, and enhance evaporation efficiency by using ceramsite mulch.Water Culture System Optimization1. Dynamic water change cycle: Change water every 5 days in summer and every 10 days in winter, retaining 1/3 of the original water to maintain bacterial balance.2. Nutrient solution management: Add 3-5 drops of specialized hydroponic nutrient solution with each water change to avoid excessive salt accumulation.Long-Term Prevention SystemEstablish an environmental monitoring mechanism: Use a soil moisture meter to monitor water content in real-time, maintaining an ideal range of 50-60%. For water culture systems, a small aerator pump can be configured to maintain dissolved oxygen levels above 4mg/L. Regularly apply beneficial bacteria such as Bacillus subtilis to enhance root resilience.By combining cause analysis with scientific prevention and treatment, not only can濒危 plants be saved, but a stable maintenance system can also be established. It is recommended to conduct monthly root health checks, promptly addressing early browning to keep Epipremnum aureum always vigorous and healthy.
