Cutting Back Peonies at the Right Time for Healthier Plants

Cutting back peonies at the right time can make a big difference in their health and appearance.

Peonies typically stop blooming in late spring or early summer, and that's when it's time to cut them back. Cutting back peonies after they finish blooming allows the plant to conserve energy and focus on developing its root system.

Cutting back peonies too early can lead to a lack of foliage, which is essential for the plant's growth and health.
