What to Do When the Money Tree's Leaves Turn Yellow with Spots
As the plant that takes on the responsibility of adding beauty to the home's greenery, the issue of yellow leaves with spots on the money tree is困扰ing many plant enthusiasts. These abnormal symptoms not only affect the ornamental value but also serve as a health alert from the plant. This article will systematically analyze five key strategies from disease prevention and control to daily maintenance to help you quickly diagnose and rescue the damaged plants.
Pathogen Invasion: Diagnosis and Treatment of Leaf Spot Disease
Identifying the Characteristics of Pathological Yellow Spots
Leaf spot disease initially manifests as white spots 2-5mm in diameter, which then expand into irregular brownish patches as the condition progresses. When humidity is high, black mold-like substances can be seen on the back of the affected spots, which need to be distinguished from physiological yellowing of the leaves.
Three-Step Emergency Response Plan
① Immediately isolate the diseased plant, prune the affected leaves, and destroy them; ② spray 50% carbendazim 800x solution weekly, focusing on the back of the leaves; ③ improve ventilation conditions and maintain a 40-60% environmental humidity.
Light Management: The Art of Balance
Repair Method for Sunburn
From 10:00 to 15:00 in the summer, 60% shading is required, using double-layer sunshades or moving the plant to an east-facing windowsill. Leaves that have been sunburned can be retained with 1/3 of their area, and gradually pruned as new leaves grow.
Light Supplement Techniques
In winter, supplement with 3 hours of LED plant lights (spectrum 450-660nm) daily, maintaining a distance of 80-100cm from the light source to avoid sunburn.
Scientific Fertilization: Key to Nutritional Control
Emergency Treatment for Fertilizer Burn
After fertilizer burn occurs, use the pot immersion method to wash the plant 3 times, each time soaking for 20 minutes. When changing the soil, retain 1/3 of the protective heart soil, and mix the new soil in a ratio of 5:3:2 of peat soil, perlite, and river sand.
Suggested Fertilization Schedule
During the growing season (April to September), apply a specialized liquid fertilizer for ornamental foliage plants every 20 days, with the concentration controlled between 1500-2000ppm. Stop fertilizing in winter and keep the potting soil slightly dry.
By systematically implementing the above prevention and treatment strategies, combined with daily temperature (18-28°C) and humidity management, it is usually possible to see new leaves sprouting normally within 2-3 weeks. It is recommended to clean the leaf surface monthly and use biological agents such as Bacillus subtilis to prevent, allowing your money tree to regain its jade-like luster.
