Yes, mangoes can develop brown spots as they ripen. These spots are often a natural part of the ripening process and do not necessarily indicate that the mango is spoiled. However, it's important to check for any signs of mold or unpleasant odors, as these could indicate that the mango is no longer safe to eat. If the brown spots are small and the rest of the mango looks and smells fine, it should be safe to consume. **

Mango trees may have brown leaves due to various reasons such as nutrient deficiencies, overwatering, underwatering, pests, diseases, or environmental stress.

Additionally, pests like mites or diseases like anthracnose can cause discoloration of the leaves. Lastly, environmental stressors such as extreme temperatures or poor soil quality can also result in brown leaves on mango trees. **

Proper care, including regular pruning, adequate watering, and disease prevention measures, can help prevent the occurrence of brown spots on mango trees. **
