What to Do When the Leaves of the Goldfish Plant Turn Yellow
The Goldfish Plant is loved for its unique fish-shaped flowers, but its caretakers are often troubled by the problem of yellowing leaves during maintenance. This article will systematically analyze the causes of yellow leaves from three core dimensions: light control, scientific watering, and temperature management, and provide actionable solutions to help you quickly restore the plant's healthy state.
In-depth Analysis of the Yellowing Leaves of the Goldfish Plant
Relationship Between Light Intensity and Leaf Health
The Goldfish Plant is a typical shade-loving plant, and excessive light can accelerate the decomposition of chlorophyll. Experimental data shows that when the light intensity exceeds 10,000 lux, the leaves will show yellowing within 3-5 days. It is recommended to use double-layer shading nets or place the plant near an east-facing window to ensure it receives 3-4 hours of scattered light daily.
Watering Frequency and Root Health Balance
Adopt the "Soaking + Spraying" combined maintenance method: soak the pot in water for 10 minutes weekly (water level not exceeding 1/3 of the pot height), combined with leaf spraying in the morning and evening. Pay special attention to using terracotta pots to improve aeration, and suggest a soil mix of decomposed leaf soil: perlite = 3:1 to ensure a drainage rate of over 200 ml per minute.
Impact of Temperature Fluctuations on the Plant
Three-month tracking observations have found that a day-night temperature difference exceeding 8°C can increase the yellowing rate of leaves by 40%. It is recommended to use a恒温垫 (constant temperature mat) to maintain a temperature of 15-18°C in winter, and place it near hydroponic plants in summer to use the transpiration effect to cool down. During special periods (before flowering), keep the temperature stable at 20±2°C.
Systematic Solution for Yellowing Leaves of the Goldfish Plant
Four-Step Environmental Control Method
1. Light Monitoring: Use a lux meter to monitor in real-time, maintaining a range of 500-800 lux. 2. Air Circulation: Install a mini circulation fan to maintain a wind speed of 0.3-0.5 m/s. 3. Humidity Management: Use an intelligent humidifier to maintain 60-70% RH. 4. Substrate Improvement: Add 5% bamboo charcoal granules every quarter to enhance water retention.
Golden Ratio of Nutrient Supply
During the yellow leaf repair period, use a liquid fertilizer with an N-P-K ratio of 3-1-2, combined with chelated iron leaf spraying weekly. Specific operation: Dissolve 1g of ferrous sulfate in 2L of water, spray evenly on both sides, and continuous use for 3 weeks can achieve a green recovery rate of over 85%.
Differential Diagnosis and Treatment of Pathological Yellow Leaves
When yellow leaves are accompanied by brown spots, it may be infected with the (T-J) disease. Immediately isolate the plant and use a 25% azoxystrobin suspension at 1500 times the concentration, spray the back of the leaves, twice a week for 3 weeks to effectively control the disease.
Through systematic environmental control and precise maintenance, the yellowing leaf problem of the Goldfish Plant can be significantly improved within 2-3 weeks. It is recommended to establish a maintenance log, record key parameters such as temperature and humidity, watering frequency, and adjust the maintenance plan in response to the plant's reactions. Regularly use an EC value tester to monitor soil salinity, maintaining the substrate EC value within the optimal range of 1.2-1.8 mS/cm.
