How to Remedy Leaf Drop in Succulents
Succulents are loved for their adorable appearance, but when their leaves fall like raindrops, it not only affects their ornamental value but may also be a distress signal from the plant. This article systematically analyzes the four main causes of leaf drop in succulents and provides corresponding care solutions.
Light Management: The Core Code of Photosynthesis
Metabolic Disorders Caused by Lack of Light
Succulents placed in dark environments for extended periods will experience leaf yellowing and dropping due to hindered chlorophyll synthesis. It is recommended to provide 4-6 hours of diffused light daily, with full sun exposure in spring and autumn, and using shade nets to filter strong UV rays in summer.
Soil Optimization: The Material Basis for Root Health
The Golden Ratio of Substrate
The ideal growing medium should include 60% particle soil (akadama, pumice) + 30% peat + 10% vermiculite. Add bone meal as a base fertilizer when repotting every year to ensure the roots can effectively absorb water and nutrients.
Water Control: The Art of Dry-Wet Cycles
The Double Standard of Watering
Adopt the "temperature + season" double judgment method: water once a week in spring and autumn when the temperature is 20-25°C; change to once every half month when it is above 30°C in summer or below 10°C in winter. Combine this with the bamboo stake test method—insert the stake into the potting soil for 2 minutes, and only water when there is no sign of moisture.
Temperature Control Strategy: The Protective Barrier of Cell Activity
Extreme Temperature Countermeasures
In the high-temperature period of summer, use a combination of "double fans + ceramic pots": turn on the circulating fans when the temperature is lower in the morning and evening, and use the breathable characteristics of red ceramic pots to achieve physical cooling. In the low-temperature phase of winter, use plant grow lights to maintain a 12-hour/day light cycle, and combine the foam box insulation method to raise the local temperature by 3-5°C.
By establishing a record system of "light log + care calendar" and adjusting the care plan based on the plant's condition, you can tell that the remedial measures are effective when new leaves appear with vibrant color and compact arrangement. Remember, each leaf drop in succulents is a special conversation with you.
