Peonies are one of the most beloved perennial plants in the garden, known for their spectacular blooms, lush foliage, and longevity. With proper care, a peony plant can thrive for decades, producing larger and more impressive blooms each year. However, their needs change with the seasons. To keep your peonies healthy and flowering beautifully, it’s important to adjust your care routine throughout the year. Here’s a season-by-season guide to help your peonies flourish in every stage of their growth cycle.

Spring: Awakening and Growth

Spring is when peonies come to life. As temperatures warm, red or pink shoots emerge from the soil, quickly developing into leafy stems.

What to do:

  • Remove mulch: If you mulched in fall for winter protection, gently remove it once the danger of frost has passed to allow new shoots to grow freely.

  • Support the stems: As the plants grow taller, install peony rings or other supports to keep heavy blooms from flopping over.

  • Water wisely: Peonies need consistent moisture during their early growth and budding stages. Water at the base to avoid wetting the foliage.

  • Fertilize lightly: Apply a balanced, slow-release fertilizer or compost around the base of the plant once new growth is about 2–3 inches tall. Avoid direct contact with the crown.

  • Watch for pests: Keep an eye out for ants (attracted to buds), botrytis blight, or other fungal diseases. Ensure good air circulation by spacing plants well and watering at the soil level.

Summer: Bloom Time and Maintenance

Peonies usually bloom in late spring to early summer, depending on your location and the variety. After the floral display, the plant enters a growth phase, building up reserves for next year.

What to do:

  • Deadhead spent blooms: Remove faded flowers just above a healthy leaf to prevent seed formation and encourage the plant to focus on root and foliage development.

  • Keep watering: Continue regular watering during dry spells, especially in the first year after planting. Deep watering once a week is usually sufficient.

  • Avoid excess feeding: Do not fertilize heavily in summer. Overfeeding can lead to excessive foliage at the expense of flower production.

  • Monitor for pests and diseases: Check for signs of fungal issues like powdery mildew or leaf blotch. Remove any affected foliage and avoid overhead watering.

Fall: Preparing for Dormancy

In fall, peonies begin to wind down. Their foliage will yellow and die back as the plant goes dormant.

What to do:

  • Cut back foliage: Once the leaves have completely yellowed or after the first hard frost, cut the stems back to 1–2 inches above the soil. This helps prevent disease from overwintering in the dead foliage.

  • Clean up debris: Remove and discard all pruned foliage—do not compost if there were signs of disease.

  • Divide and transplant: Fall is the best time to divide or move peonies if needed. Dig up the plant carefully, divide the root clump, and replant with the eyes (buds) 1–2 inches below the soil surface.

  • Apply light mulch: In colder regions, apply a light layer of mulch or compost over the root zone for winter protection, especially for newly planted or divided peonies. Remove it in early spring.

Winter: Rest and Protection

During winter, peonies are dormant. They don’t require much attention, but some protection ensures a healthy return in spring.

What to do:

  • Leave the mulch in place: Keep any mulch over the crown until spring temperatures rise to protect the buds from freeze-thaw cycles.

  • Avoid disturbing the soil: Peonies don’t like being moved frequently. Avoid digging around the roots during winter.

  • Monitor weather conditions: In extremely cold climates, additional insulation with straw or evergreen boughs can help shield the crown from deep freezes.

General Tips for Year-Round Peony Success

  • Sunlight: Peonies need full sun (at least 6 hours per day) to bloom well. Too much shade results in fewer or no blooms.

  • Spacing: Plant peonies with enough space between them (about 3–4 feet) for good air circulation and growth.

  • Soil requirements: Well-drained, slightly acidic to neutral soil (pH 6.5–7) is ideal. Avoid soggy soil, which can lead to root rot.

  • Patience with young plants: Peonies may take a couple of years to bloom after planting or transplanting. During this time, focus on maintaining healthy foliage and root development.

Conclusion

Peonies are incredibly rewarding plants that offer decades of beauty when cared for properly. Their seasonal cycle—from dormant winter roots to vibrant summer blooms—requires specific attention at each stage. With a little effort in spring, summer, fall, and winter, you can enjoy a thriving peony garden year after year. Whether you grow them for cut flowers, curb appeal, or simply their timeless charm, seasonal care is the secret to their success.
