During use, the phenomenon of leaf drop in bonsai occurs from time to time, which not only affects the aesthetics of the bonsai but may also cause serious damage to its growth. This article will analyze the reasons for leaf drop in bonsai in detail and provide corresponding solutions to help enthusiasts solve this problem.
Reasons for Bonsai Leaf Drop1. Improper Water Management
Water is essential for plant growth, but too much or too little water can cause leaf drop in bonsai. Overwatering can lead to root hypoxia, thus affecting normal plant growth; while insufficient watering can cause the plant to lack water, leading to the loss of vitality in the leaves.

Light is a necessary condition for plants to perform photosynthesis. Insufficient light can lead to slow growth, yellowing, and shedding of leaves.
3. Uncomfortable Temperature
Bonsai has a strong adaptability to temperature, but both high and low temperatures can have adverse effects on plant growth. High temperatures can cause leaf wilting and shedding, while low temperatures can lead to frostbite.
4. Soil Issues
Soil is the foundation of plant growth, and soil quality directly affects plant growth. Soil that is too compact, poor in drainage, or deficient in fertility can lead to leaf drop in bonsai.
5. Diseases and Pests
Diseases and pests are common causes of leaf drop in bonsai. Insects like aphids, red spiders, and diseases like powdery mildew can damage plant leaves, leading to leaf shedding.
Solutions for Bonsai Leaf Drop1. Reasonable Watering
Based on the type and growth stage of the bonsai, control the watering frequency and amount reasonably to avoid overwatering, which can cause root hypoxia; ensure the soil is moist and avoid drought.
2. Appropriate Increase in Light
Place the bonsai in a sunny location to ensure the plant can perform photosynthesis adequately. If conditions do not allow, artificial light sources can be used to supplement light.
3. Temperature Control
Based on the plant's growth habits, place the bonsai in a suitable temperature environment. During high summer temperatures, the room temperature can be lowered appropriately; during low winter temperatures, pay attention to keeping warm.
4. Improving Soil
Regularly replace the soil to keep it loose, breathable, and well-drained, and apply organic fertilizers to improve soil fertility.
