Analysis of the Reasons for Bonsai Leaf Drop1. Improper Water Management
Water is the foundation for the growth of bonsai, and improper water management can lead to leaf drop, including the following reasons:

(2) Underwatering: Dry bonsai soil causes the plant to lack water, resulting in withered and fallen leaves.
2. Insufficient Lighting
Light is an important condition for the growth of bonsai. Insufficient light can lead to slow growth or even leaf drop, including the following reasons:
(1) Long-term placement in a dark environment: Prolonged exposure to dim conditions can lead to insufficient photosynthesis, causing leaves to turn yellow and fall off.
