With the arrival of autumn, many flower enthusiasts have noticed that their potted cassia trees suddenly started to shed all their leaves, causing what was once a delightful plant to become lackluster. The complete defoliation of cassia trees is not without cause, and we will now analyze the reasons and provide corresponding maintenance strategies.
Reasons for the complete defoliation of cassia trees1. Environmental factors
(1) Insufficient light: Cassia trees enjoy sunlight, and prolonged exposure to dim environments can cause leaves to turn yellow and fall off.
(2) Temperature changes: The optimal temperature for the growth of cassia trees is between 15-30℃, and if the temperature is too low or too high, it can lead to leaf drop.
(3) Air humidity: Cassia trees thrive in humid environments, and excessively low air humidity can cause leaves to dry out and fall off.
2. Improper maintenance
(1) Improper watering: Too much or too little watering can lead to leaf drop, with excessive watering causing root rot and insufficient watering resulting in leaf drying.
(2) Improper fertilization: Too much or too little fertilization can affect the growth of cassia trees, with excessive fertilization causing leaf yellowing and drop, and insufficient fertilization leading to slow leaf growth.
(3) Diseases and pests: Diseases and pests such as powdery mildew and aphids are also reasons for the complete defoliation of cassia trees.

6. Prevent diseases and pests
Regularly inspect the plant and promptly control any diseases or pests found, using chemical or biological control methods.
