What to Do When the Money Tree's Leaves Turn Yellow
As a common ornamental plant in offices and homes, the yellowing leaves of the money tree have been困扰ing many plant growers. This article systematically analyzes the four key factors leading to yellow leaves and provides highly operable solutions to help you quickly restore the plant's healthy condition.
I. Scientific Adjustment of Water Supply
1.1 Treatment for Yellow Leaves Due to Water Deficiency
When there is a dry crack layer of more than 3cm on the soil surface, the immersion pot method should be used to replenish water: place the pot in a basin of water and soak for 15 minutes, then remove and drain after the bubbles disappear, repeating this process twice a week until the leaves regain their luster.
1.2 Rescue for Yellow Leaves Due to Waterlogging
If waterlogging exceeds 24 hours, immediately remove the pot and check the roots, cut off the black rotten roots, disinfect with carbendazim, and repot using a breathable matrix with 40% perlite. Maintain an environmental humidity of over 60% during the rescue period.
II. Optimization of Light Environment
2.1 Improvement Measures for Insufficient Light
In north-facing rooms, it is recommended to use LED plant grow lights, supplementing light for 4 hours daily (8000-10000lux) at a distance of 50cm from the plant. Rotate the pot clockwise by 45 degrees every 2 weeks to ensure even light exposure.
2.2 Repair Process for Sunburn Damage
When brown spots appear on the leaf surface, immediately move the plant to a diffused light environment. Cut off the leaves with more than 50% damage and spray with a 0.1% potassium dihydrogen phosphate solution, repeating this twice a week for continuous care.
III. Accurate Temperature Control Strategy
3.1 Response to Low Temperature Injury
When the room temperature in winter is below 12℃, wrap the main stem with a plant insulating cover and place a 3cm thick layer of pine bark as an insulating layer at the root. Change the watering to warm water at 25℃ to avoid low temperature stimulation.
3.2 Management of High Temperature Stress
When the temperature exceeds 35℃ in summer, start the cooling program: spray twice a day, early morning and evening, and use a mini circulating fan to promote air circulation. Use a sunshade net at noon to filter 60% of the strong light.
IV. Comprehensive Pest and Disease Control System
For common red spiders (web-like substances on the back of leaves), use dinotefuran suspension at 2000 times; for scale insects (white fluffy substances on branches), choose 22% thiamethoxam·lambda-cyhalothrin suspension; for leaf spot disease (irregular brown spots), spray 50% carbendazim wettable powder at 800 times, once a week for 3 consecutive weeks.
By following the above systematic solutions, combined with monthly root feeding with a nutrient solution (N-P-K=15-5-10), the plant's vitality can usually be fully restored within 2-3 months. The key is to timely detect early symptoms and prevent cumulative problems that can cause irreversible damage. Regularly wiping the leaves with a damp cloth can not only maintain photosynthetic efficiency but also detect signs of pests and diseases early.
