Why the Roots of the Epipremnum aureum Are Rotting
As a star candidate for indoor greenery, Epipremnum aureum is loved for its powerful vitality and air purification function. However, many plant enthusiasts often encounter the problem of root rot during maintenance, with the originally green leaves gradually turning yellow and falling off. This article will systematically analyze the specific causes of root rot in Epipremnum aureum and provide professional solutions.
Deep Analysis of Root Rot in Soil-Grown Epipremnum aureum
Water Management Failure
60% of the root rot cases in soil-grown Epipremnum aureum are caused by improper watering. Although Epipremnum aureum prefers a humid environment, its fleshy roots are extremely sensitive to waterlogging. It is recommended to use the " fingertip test method ": water when the soil is dry 2 centimeters deep, water thoroughly once a week in summer, and extend to 10-15 days in winter. Pay attention to choosing a ceramic pot with a drainage hole at the bottom, and enhance breathability by using volcanic rock as the base layer.
Soil Microbial Imbalance
Untreated soil may carry pathogenic bacteria such as Fusarium. Professional maintenance suggestions: new soil should be steamed at high temperatures for 30 minutes or sprayed with a carbendazim solution (at a 1:1000 ratio) before use, and old soil should be replaced every six months. When root rot occurs, immediately implement the "three-step rescue method": ① cut off the blackened and rotting roots, retain healthy white roots ② soak in potassium permanganate solution for disinfection ③ replace with sterile nutrient-rich soil and replant.
Key Points for Root Maintenance of Water-Grown Epipremnum aureum
Water Quality Control Standards
Water-grown Epipremnum aureum is recommended to use tap water that has been standing for 24 hours, with water temperature maintained between 18-25°C. The TDS value (total dissolved solids) should be controlled within the range of 50-150ppm, and water should be changed immediately if it exceeds 200ppm. A special hydroponic nutrient solution can be added, but the concentration should be reduced to half of what is indicated in the instructions to avoid chemical burns.
Systematic Maintenance Plan
Establish a scientific maintenance cycle: change water weekly in spring and autumn, every 3-4 days in summer, and every 10-12 days in winter. Clean the inner walls of the container thoroughly and remove the slime film with a soft brush each time you change the water. Combined with LED plant growth lights for 4 hours of daily illumination can effectively enhance the root's resistance to disease.
By precisely controlling moisture, strictly disinfecting, and establishing a scientific maintenance system, the probability of root rot in Epipremnum aureum can be significantly reduced. It is recommended to conduct a root health check every month and address early symptoms immediately. Remember, healthy white roots are the cornerstone of vigorous growth in Epipremnum aureum.
