Attention Points for Repotting Epipremnum aureum
Epipremnum aureum, as a common indoor green plant, the repotting operation directly affects its subsequent growth state. Many plant enthusiasts find that leaves become wilted or yellow after repotting, often due to neglect of care details. Standardizing the operation process and avoiding common mistakes can help Epipremnum aureum quickly adapt to the new environment and thrive.
Necessary Preparations Before Repotting
Accurate Grasp of Water Control Timing
It is recommended to stop watering 5-7 days in advance, waiting for the soil to be slightly dry before proceeding. In summer, this can be shortened to 3 days of water control, while in winter, it needs to be extended to about 10 days. A bamboo skewer can be inserted into the potting soil to test the moisture level, and it can be removed from the pot once no soil clings to it.
Selection of Pot and Substrate
The diameter of the new pot should be 3-5 centimeters larger than the original pot, preferably choosing a breathable clay pot. The substrate is recommended to use a mixture of decomposed leaf soil, perlite, and coconut bran in a ratio of 4:3:3 to ensure loose, breathable, and moderately water-retaining properties.
Key Operations During Repotting
Fine Treatment of Root System
After shaking off the old soil, use a pair of scissors disinfected with alcohol to trim the blackened and rotting roots at a 45-degree angle. Retain healthy white roots, and keep the overgrown aerial roots to 15 centimeters. The amount of trimming should not exceed 1/3 of the total root mass.
Scientific Method of Disinfection
Soak the roots in a carbendazim solution (1:1000) for 20 minutes and then let them dry. The new soil needs to be treated at high temperatures: sealed in a bag and microwaved at medium heat for 3 minutes, or spread out and exposed to sunlight for 2-3 days.
Post-Repotting Recovery Management
Environmental Control During the Acclimatization Period
Place the plant in a scattered light environment for 14-21 days, maintaining a temperature of 18-25°C. Use a humidifier to keep the humidity at 60%, avoiding direct blows from the air conditioner. Do not water for the first 3 days, and on the 4th day, slowly pour the settling water along the edge of the pot.
Key Points to Observe for Growth Status
The unfolding of new leaves indicates successful acclimatization, at which point a diluted leaf plant nutrient solution (2000 times) can be applied. If the leaf tips become burnt, check if fertilization was too early or the lighting too strong.
Through systematic repotting operations and meticulous post-care, Epipremnum aureum can not only quickly recover its vitality but also achieve a more vigorous growth. Mastering the rhythm of stopping water and controlling roots, the key points of disinfection, and the temperature and humidity management during the acclimatization period can effectively avoid adverse reactions after repotting, allowing Epipremnum aureum to maintain a lush green ornamental state continuously.
