Why is mulberry trees leaves turning yellow?

Mulberry trees' leaves turning yellow can have several causes, including:

1. Nutrient deficiency: Mulberry trees require specific nutrients, such as nitrogen, phosphorus, and potassium, for healthy growth. A deficiency in any of these nutrients can cause the leaves to turn yellow.

2. Drought: Insufficient watering or prolonged dry spells can lead to yellowing of mulberry tree leaves.

3. Overwatering: Mulberry trees are susceptible to overwatering, which can cause the roots to rot and the leaves to turn yellow.

4. Pest or disease: Fungal diseases, such as powdery mildew, and pests, such as aphids and spider mites, can cause mulberry tree leaves to turn yellow.

5. Environmental factors: Extreme temperatures, such as frost or excessive heat, can also cause mulberry tree leaves to turn yellow.

To determine the exact cause of the yellowing leaves and address it appropriately, it's best to observe the tree closely, check the soil moisture, and inspect for signs of pests or diseases. If necessary, you can consult with a gardening expert or arborist for further assistance.
