Osmanthus trees have a high demand for water. If there is prolonged drought or insufficient watering, it can lead to yellowing of the leaf tips. This is because insufficient water will cause the leaf cells to lose water, which in turn affects photosynthesis and causes the leaves to turn yellow.
2. Excessive water
Excessive watering can also lead to yellowing of the tips of Osmanthus tree leaves. This is because waterlogging in the soil can cause root hypoxia, affecting the absorption of nutrients by the roots and causing the leaves to turn yellow.
3. Improper application of fertilizer
Excessive application of fertilizer or improper fertilization can lead to a high concentration of nutrients in the soil, causing root damage and affecting leaf growth, resulting in yellowing of the leaf tips.
4. Pest and disease infestation
Pests such as aphids and red spiders will absorb the nutrients of Osmanthus trees, causing the leaves to turn yellow. Fungal diseases such as leaf spot and anthracnose can also cause the tips of the leaves to turn yellow.
