What to Do When Money Tree Leaves Have White Spots
When white spots appear on the leaves of a money tree, it is not only a distress signal from the plant but also a critical moment for the caregiver to take immediate action. As a common ornamental green plant in home environments, the health of the money tree directly affects the aesthetics of the space and its feng shui implications. This article will systematically analyze the formation mechanism of white spots and provide a step-by-step solution.
Emergency Response Plan for White Spot Disease
Isolation and Pruning of Diseased Leaves
Diseased leaves should be pruned immediately using sterilized scissors, with the cut made 1 cm away from healthy tissue at an angle. It is recommended to perform this in the morning when the plant's transpiration is weaker, and applying charcoal powder after cutting can effectively prevent secondary infections. Pruning tools need to be soaked in 75% alcohol for 10 minutes to sterilize.
Precise Medication Control
Carbendazim should be diluted at a ratio of 1:800 and mixed with 0.1% detergent to enhance adhesion. It is suggested to use a misting spray bottle, focusing on the underside of the leaves. After applying the medication, set up a temporary shade shelter to prevent strong sunlight from breaking down the medicine. For pests like scale insects, alternating use of imidacloprid and matrine biological preparations is recommended.
Optimization Strategies for Environmental Regulation
Lighting and Ventilation Management
In spring and summer, maintain 4-6 hours of scattered light daily, and use shade nets to control light intensity between 20,000-30,000 Lux. In winter, ensure the environmental temperature is ≥15°C and use a circulating fan to maintain air circulation, with a recommended air exchange rate of more than three times the volume of the plant per hour.
Water and Fertilizer Synergy in Maintenance
During the recovery period, use the pot immersion method to replenish water, keeping the substrate moisture between 40%-60%. Apply slow-release fertilizer with a phosphorus-potassium ratio of 2:1, combined with seaweed foliar fertilizer to enhance stress resistance. Special attention should be given to supplementing chelated iron during the period when new leaves are unfolding, which can prevent iron deficiency chlorosis.
Through systematic treatment plans, coupled with continuous environmental optimization, about 90% of white spot issues can be effectively controlled within 45 days. It is recommended to conduct foliar inspections monthly and maintain a maintenance log recording temperature and humidity changes. Remember, prevention is better than cure, and maintaining a stable environment is the key to preventing disease recurrence.
