What to Do When Osmanthus Tree Leaves Turn Yellow
The yellowing of osmanthus tree leaves may be caused by excessive watering, long-term water deficiency, or exposure to direct sunlight. Normally, they should be cared for in a well-ventilated and sunny environment, and special attention should be paid to shading during the summer. If yellowing is caused by too much watering, stop watering immediately. If it is due to insufficient or excessive fertilization, fertilize reasonably, noting that once every two weeks is sufficient.
Common Reasons for Yellowing Osmanthus Tree Leaves
1. Excessive Watering: Too much watering of the osmanthus tree can cause the potting soil to accumulate water, leading to the rot of fibrous roots, weakened ability to absorb water and nutrients, and yellowing of the leaves.
2. Long-Term Water Deficiency: Insufficient watering of the osmanthus tree can cause the leaves to lose water through evaporation, leading to yellowing due to lack of moisture.
3. Sunburn: Placing the osmanthus tree in direct sunlight during the summer can easily cause leaf yellowing and falling due to high temperatures.
Methods to Treat Yellowing Osmanthus Tree Leaves
1. Temperature: If yellowing is caused by inappropriate temperatures, the plant needs to be cared for in a suitable temperature environment, with proper cooling in the summer and indoor placement in the winter.
2. Watering: If yellowing is caused by excessive watering, stop watering immediately and then place the plant in a location with diffused light and good ventilation to drain excess water.
3. Fertilization: If yellowing is due to insufficient or excessive fertilization, fertilize reasonably, noting that once every two weeks is sufficient. Fertilization can be omitted in the summer and winter.
Preventing Yellowing of Osmanthus Tree Leaves
The osmanthus tree should be cared for in a well-ventilated and sunny environment. Potted plants should be moved indoors to a sunny location during the winter, maintaining a room temperature of 5℃ or higher. Generally, apply nitrogen fertilizer once in the spring, phosphorus and potassium fertilizer once in the summer, and organic fertilizer once before winter.
