Why Does a Money Tree Wither?
As a star variety of indoor green plants, the money tree is deeply loved for its auspicious meaning and upright posture. However, when the leaves turn yellow and wither, it often leaves caretakers at a loss. This article will systematically analyze the three main causes of withering, from root care to light management, and provide scientific solutions.
I. Improper Root Care Causes Withering
1.1 Overwatering Leads to Root Rot
More than 80% of withering cases are caused by uncontrolled watering. The money tree's swollen stem has a water storage function, and it is recommended to water once every 15-20 days in spring and autumn, and extend to 30 days in winter. You can use the bamboo stake insertion method to check the moisture of the potting soil, water when the 5cm deep area is dry.
1.2 Correct Potting Techniques
Immediate action is required after discovering root rot: ① cut off the black decayed roots, leaving the healthy white ones; ② soak in carbendazim for 30 minutes; ③ replace with sandy loam soil containing perlite, and use a support frame to stabilize the plant initially.
II. Imbalance in Light Management
2.1 Characteristics of Sunburn Injury
Burnt leaf tips accompanied by bleached spots are typical symptoms of sunburn. In summer, avoid direct sunlight from 11 to 15 o'clock, and place it 1.5 meters away from the east-facing windowsill, or use a 40% shading rate curtain to adjust.
2.2 Lighting Techniques
In winter, when there is insufficient sunlight, it is recommended to use a full-spectrum plant light to supplement for 4 hours daily, maintaining a distance of more than 50 cm. Regularly rotate the pot to ensure even light exposure on all sides.
III. Maintenance of Nutrient Supply System
3.1 Deficiency Symptoms Cycle
Thin new leaves and yellowing old leaves falling off are signals of nutrient deficiency. During the growing season (April to October), apply a balanced NPK liquid fertilizer every 20 days, dilute to half the standard concentration following the principle of "frequent application of light fertilizer."
3.2 Organic Fertilizer Application Guidelines
Decomposed sheep manure fertilizer can be mixed with potting soil at a ratio of 1:10, and used when repotting in spring every year. Note that the fertilizer should be kept more than 5 cm away from the main root to avoid root burn.
By precisely controlling the watering rhythm, creating a diffused light environment, implementing a scientific fertilizing plan, and regularly checking the leaf condition, the withered money tree can recover within 2-3 months. It is recommended to record maintenance data every quarter in a gardening journal to form a personalized care plan.
