Causes and treatments for yellow leaves of Osmanthus fragrans

1. Unsuitable soil

Reason: It likes slightly acidic soil. If the soil becomes alkaline after excessive watering, the plant will grow poorly and its leaves will turn yellow.

Measures: Add appropriate amount of acidic substances to the soil and replace it with new fertile soil regularly.

2. Insufficient light

Reason: It likes light. If there is insufficient light in the growing environment, the leaves will turn yellow.

Measures: Ensure sufficient sunlight during the growing period, and appropriate pruning is also required to increase light transmittance.

3. Improper water and fertilizer

Reason: Water and fertilizer are important factors to support growth. Lack of water and fertilizer will cause the plant to become weak and the leaves to turn yellow. However, if too much water and fertilizer are given, the roots will not be able to bear it and the leaves will turn yellow.

Measures: Apply water and fertilizer correctly, especially when the growth is vigorous. When excessive amounts are given, it is necessary to promote the discharge of excess water and fertilizer.

4. Infections and diseases

Cause: If the plant is not properly cared for, it may develop chlorosis, a disease that causes the leaves to turn yellow.

Measures: After discovering the infection, remove the diseased leaves in time and then spray medicine for treatment.

5. Metabolism

Cause: Metabolism during plant growth causes the leaves to naturally turn yellow, mainly at the bottom.

Measures: In this case, just cut off the yellow leaves at the bottom.
