First, the absorption of water and nutrients of newly planted osmanthus trees decreased after root system injury. When the leaves evaporate more water, the roots can't provide a lot of water in time, which will cause the leaves to dry up, especially the tip. Secondly, the nutrients are reduced, and the leaves are insufficient in the process of photosynthesis, which leads to the symptoms of yellow leaves. When the root system returns to normal growth, such problems will be reduced and gradually return to normal.

2. If the potted osmanthus tree is indoors, it can be moved into a sunny and ventilated place indoors to prevent dehydration and death after sun exposure. If osmanthus trees are outdoors, you can use a sunshade net to prevent dehydration and death. The trunk can be protected by spraying cotton cloth, which can improve the survival rate.

Third, if the yellow leaves continue to wither severely, it can be sprayed with 800 times of the solution of Duoyinling to treat diseases and prevent diseases, and put an end to root rot caused by bacterial infection.
