When Should My Peonies Be Trimmed Back?

Peonies are essential for plant health, as they help create a sturdy framework for their beautiful blooms. To maintain their health and shape, peonies need to be cut back during the growing season. Diseases can be controlled by removing diseased foliage during the growing season and by cuttin.

There are four main reasons for pruning peonies: increasing bloom size, cutting flowers, deadheading, and winter preparation. The best methods for herbaceous and tree peonies include pruning in spring, summer, and fall for optimal growth and bloom. Herbaceous peonies (Paeonia lactiflora) require an annual prune for maintained health.

The best time to prune a tree peony is right after it blooms, after the first frost and when the foliage has turned yellow. This helps keep the plant healthy and free of disease when the blooms return next spring. If you’re growing a tree peony, pruning can be done in fall or spring.

Ponies are typically cut back in late fall after the foliage has turned brown and died back. This helps prevent disease and prepares the plant for winter. Peonies can be cut and deadheaded in the spring and summer but must be cut down in the fall to control disease. After the first hard frost in fall, cut back peonies to about 3 inches (8 cm) high or all the way to the ground.

Cleaning the blooms is fine, but leave the foliage until late fall before cutting back the flowers. By following these guidelines, you can ensure the health and beauty of your peony plants.
