This article will deeply analyze the causes of yellowing leaves from three core dimensions and provide actionable rescue plans.
Diagnostics for Yellowing Leaves of Epipremnum Aureum
1. Improper Watering Management
• Root Rot due to Waterlogging: Long-term moist potting soil causes root asphyxiation, manifested by blackened leaf tips and wilted new leaves• Drought due to Lack of Water: Lower leaves turn yellow and curl first, with the whole plant drooping severely due to dehydration• Detection Technique: Insert a bamboo stick into the potting soil and observe the moisture after 2 hours
2. Imbalanced Light Intensity
• Sunburn: Direct sunlight causes burn spots on the leaf surface, with obvious yellowing between the veins• Chlorosis due to Lack of Light: New leaves are thin and pale, with abnormally long internode spacing• Ideal Illumination: 2000-3000 lux scattered light environment
3. Abnormal Nutrient Supply
• Root Burn due to Fertilizer Damage: Leaf margins turn brown 3-5 days after fertilizing, accompanied by white salt and alkali crystals• Chlorosis due to Lack of Elements: Yellowing with net-like patterns between veins when magnesium is deficient• Fertilizing Schedule: Apply a 1:1000 diluted liquid fertilizer every 15 days during the growing season

1. Scientific Watering Techniques
• Immersion Method: Soak the pot in water at a level of 1/3 for 10 minutes• Bamboo Stick Test: Regularly check the moisture cycle of the potting soil weekly• Water Quality Requirement: Still tap water or rainwater left overnight
2. Optimization of Light Environment
• Eastern Window Sill: Receive 2-3 hours of gentle morning light daily• Supplemental Lighting Solution: LED plant lights provide supplemental lighting for 4 hours daily• Sun Protection Technique: Use a shade cloth with 60% light blocking rate
3. Root System Repair Process
• Root Pruning Standard: Retain healthy white roots, cut off the browned ones• Disinfection Treatment: Soak in a 1000x solution of carbendazim for 20 minutes• Potting Point: Use a new matrix of perlite: peat soil = 1:3
