When peonies begin to fade, most don’t know what to do. Here are the 10 most critical tasks & why.

Why: Heavy blooms can bend or break stems; post-bloom, lighter support prevents damage as stems recover.

7. Monitor for Pests and Disease

Why: Aphids, thrips, or fungal infections can spread after flowering. Early detection keeps plants healthy.

8. Avoid Cutting Back Immediately

Why: Wait until foliage naturally yellows in the fall. Premature cutting removes stored energy essential for next season.

9. Divide Only When Necessary

Why: Peonies prefer being undisturbed; divide only if overcrowded, best done in fall.

10. Clean Up Garden Debris

Why: Remove fallen petals and leaves to reduce fungal spores and pests that overwinter in the debris.

Following these tasks helps ensure strong roots, healthy foliage, and spectacular blooms next season.
