How to Save a Money Tree with Yellowing Leaves
The Money Tree, as the "wealth attractor" in the indoor green plant world, has its leaf yellowing issue troubling many plant enthusiasts. This article summarizes 10 years of gardening experience to systematically analyze the causes of yellowing leaves and provide scientific treatment solutions to help you quickly restore the vitality of the plant.
One, Environmental Factors Causing Yellowing Leaves in Money Trees
1.1 Key to Light Control
Direct strong sunlight is the main cause of yellowing leaves in summer, leading to burn-like yellow spots on the leaves. It is recommended to use double curtains to filter the light or move the plant to a position 1.5 meters away from the east-facing windowsill. In winter, the plant can be exposed to full sunlight, but it should be rotated 180 degrees weekly to ensure even light exposure.
1.2 Principle of Temperature and Humidity Balance
Temperatures below 12°C or above 35°C can trigger stress-induced yellowing leaves. Maintain a growth temperature of 18-28°C, combined with morning and evening foliar sprays (using pure water to avoid scale), and place ceramic stone water trays at the bottom of the pot to create a microclimate.
Two, Pathological Yellow Leaf Treatment Plan
2.1 System for Preventing Wilt Disease
Initial spots can be treated with a cotton swab蘸取 medical hydrogen peroxide. In severe cases, use benomyl (diluted 1500 times) to spray the entire plant once a week for three weeks. Simultaneously, replace the top 5 cm of soil to block the spread of pathogens.
2.2 Root Health Management
Immediate repotting is required for waterlogged and rotting roots, using the "three-level root pruning method": retain white healthy roots → prune browned roots → remove black decayed roots. Soak in potassium permanganate (0.1% concentration) for 30 minutes before repotting with new soil.
Three, Long-Term Scientific Maintenance Mechanism
3.1 Intelligent Watering Solution
In spring and autumn, use the "bamboo skewer test": insert a barbeque skewer into the potting soil for 15 minutes and then pull it out; water only when the tip is slightly moist. In summer, combine with the immersion pot method (once a month), and in winter, use the slow watering method along the pot wall.
3.2 Precision Fertilization Strategy
In the growing season, use the "3+2 nutrient package": three times of liquid fertilizer for ornamental foliage plants (N-P-K 15-5-10) alternated with two times of seaweed extract. After fertilizing, enhance ventilation within 6 hours to avoid yellowing leaves from fertilizer damage.
Through the above systematic treatment solutions, more than 80% of yellowing leaf issues can be improved within three weeks. The key is to establish a "prevention-diagnosis-treatment" maintenance loop, regularly observe the leaf undersides, and check the potting soil to keep the Money Tree continuously vibrant and attracting wealth.
