Understanding Why Leaves Turn Yellow
Yellowing leaves can result from various factors, including overwatering, underwatering, nutrient deficiencies, pests, or disease. Recognizing the cause is essential before pruning. Sometimes, yellow leaves are simply a natural part of the plant’s lifecycle, especially older foliage.
