Peonies come in early, mid, and late-season blooming varieties. To extend the blooming season, plant a mix of these types. Early bloomers like 'Early Scout' or 'Coral Charm' start flowering in late spring, while mid-season varieties such as 'Sarah Bernhardt' follow. Late bloomers like 'Kansas' or 'Duchesse de Nemours' can extend the display into early summer. By selecting a diverse range, you ensure staggered blooms for a longer-lasting show.
Peonies thrive in full sun (6+ hours daily) but benefit from light afternoon shade in hotter climates to prevent premature wilting. Plant them in well-draining, fertile soil with a neutral pH (6.5–7.0). Avoid low-lying areas where cold air settles, as late frosts can damage buds. Proper site selection ensures healthy plants that bloom consistently and resist disease.
Peonies need consistent moisture, especially during bud formation and flowering. Water deeply once a week, ensuring the soil stays moist but not waterlogged. Mulch with 2–3 inches of organic material (e.g., compost or bark) to retain moisture and regulate soil temperature. Avoid overhead watering to prevent fungal diseases, which can shorten bloom time.
Feed peonies in early spring as shoots emerge, using a balanced fertilizer (e.g., 10-10-10) or compost. Avoid high-nitrogen fertilizers, which promote foliage over flowers. A second light feeding after blooming can support root growth for next year’s blooms. Healthy plants produce more flowers over a longer period.
Remove faded flowers promptly to prevent seed production, which diverts energy from new blooms. Cut stems back to just above a healthy leaf node. Deadheading encourages secondary buds on some varieties to open, slightly extending the bloom season. It also keeps plants looking tidy and reduces disease risk.
Botrytis blight and powdery mildew can shorten blooming. Ensure good air circulation by spacing plants 3–4 feet apart. Remove infected foliage immediately and dispose of it (do not compost). Treat severe cases with fungicides. Deer and ants are common pests; use repellents or physical barriers to protect buds.
Heavy blooms can cause stems to droop, especially after rain. Use peony rings or stakes early in the season to keep flowers upright. This prevents breakage and ensures blooms last longer on the plant rather than being lost to damage.
Peonies dislike being moved and may take 2–3 years to rebloom after transplanting. If division is necessary, do it in early fall and replant divisions at the same depth (buds 1–2 inches below soil). Minimizing root disturbance helps maintain consistent blooming year after year.
Harvest peonies in the "marshmallow" stage (buds soft to the touch) for indoor arrangements. Place stems in cool water immediately and keep them out of direct sunlight. Cutting blooms reduces stress on the plant, allowing remaining buds to develop fully and prolonging the overall display.
