Why are the leaves on the persimmon tree turning yellow?

Leaves on a persimmon tree may turn yellow due to various factors, including nutrient deficiencies, particularly nitrogen, or environmental stress such as overwatering or drought. Additionally, pests or diseases can cause yellowing as well. Seasonal changes can also lead to yellowing as the tree prepares for dormancy in the fall. It's important to assess the overall health of the tree and its growing conditions to determine the specific cause.
