What causes peony buds to turn brown and not produce flowers?

Peony buds may turn brown and fail to produce flowers due to several factors, including environmental stress, such as extreme temperatures or insufficient water. Fungal diseases, like botrytis blight, can also attack buds, leading to browning and decay. Additionally, nutrient deficiencies or improper pruning can disrupt the plant’s ability to develop healthy blooms. Ensuring proper care, including adequate watering, appropriate fertilization, and disease management, can help prevent these issues.
