Why Is the Green Philodendron's Leaf Rotting at Home? You Must Have Ignored These Points
As the preferred indoor air purifying plant, the green philodendron is deeply loved for its vigorous vitality. However, the issue of leaf rot during maintenance has troubled many plant enthusiasts. This article will systematically analyze the five key factors leading to green philodendron leaf rot and provide professional solutions.
Environmental Control Points
Air Circulation Management
In winter, special attention should be paid to the rhythm of ventilation, it is recommended to open windows for ventilation between 11:00-14:00 when the temperature is higher. The green philodendron should be placed more than 1.5 meters away from the window to avoid direct cold wind. In summer, a circulating fan can be used to assist air flow, ensuring that the air replacement rate reaches over 40% per hour.
Temperature and Humidity Balance
The optimal growth temperature for green philodendron is between 18-28°C. When the temperature drops below 12°C, anti-freezing measures should be initiated. It is recommended to use thickened pots for insulation in winter, and at night, a transparent plastic bag can be placed over the plant to form a mini greenhouse. Humidity should be controlled within the range of 60-75%, and humidity can be maintained using a tray with water and stones.
Maintenance Operation Standards
Scientific Watering System

Establish a seasonal watering calendar: keep it at 3-4 times/week in spring and autumn, 2 times/week in summer, and extend to 5-7 times/week in winter. Use the "fingertip test" – insert the second joint of the index finger into the potting soil, and water when it's dry. It is recommended to use a long-spouted watering pot to slowly pour water along the pot wall, avoiding water accumulation in the leaf heart.
Trauma Treatment Solution
If mechanical damage to the leaves is found, they should be isolated and treated immediately. Disinfect the scissors with 75% alcohol and cut obliquely at the base of the petiole. Apply charcoal powder or cinnamon powder to the wound for physical disinfection, and avoid spraying water for 3 days after treatment.
Disease Prevention and Control System
Fungal Disease Response
(T-J) disease prevention and treatment use a three-step therapy: initially spray with garlic extract (1:10) daily, in the middle stage use 50% carbendazim 800 times liquid every other day, and in severe cases,配合代森锰锌进行土壤消毒. Maintain 6 hours of scattered light during the treatment period.
Bacterial Disease Management
When leaf spot disease breaks out, remove the diseased leaves immediately and spray the whole plant with Bordeaux mixture. It is recommended to pour EM bacteria solution (1:500) monthly to enhance the plant's disease resistance. Regularly disinfect the cultivation environment with a UV germicidal lamp, each照射15 minutes.
Through systematic environmental control, standardized maintenance operations, and scientific disease prevention and control, the issue of green philodendron leaf rot can be effectively resolved. It is recommended to establish a maintenance log, recording temperature and humidity changes, watering cycles, and plant conditions, gradually mastering the subtle balance of green philodendron growth, allowing this natural air purifier to continue to thrive.
