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

1. Deadhead Spent Blooms

Why: Removing faded flowers prevents the plant from putting energy into seed production, redirecting it to root and foliage growth.

2. Leave Healthy Foliage Intact

Why: The leaves continue photosynthesis, storing energy for next year’s blooms. Cutting too early can weaken the plant.

3. Water Deeply but Sparingly

Why: Peonies need moisture to replenish roots, but overwatering can cause rot or fungal issues.

4. Mulch Around the Base

Why: Mulch retains soil moisture, regulates temperature, and suppresses weeds without covering the crown.

5. Fertilize Lightly

Why: A balanced, slow-release fertilizer supports root development without encouraging weak, floppy stems.

6. Support Stems if Needed
