Peonies are beloved for their lush, fragrant blooms and hardy nature, making them a perfect addition to gardens across Minnesota. To ensure your peonies thrive in the Land of 10,000 Lakes, follow our comprehensive guide on peony care tailored specifically for Minnesota’s climate and growing conditions:
Choosing the Right Peonies:
- Variety Selection: Opt for peony varieties that are well-suited to Minnesota’s climate, such as ‘Sorbet’, ‘Double Fernleaf’, or ‘Coral Sunset’.
- Planting Time: Plant peonies in early fall (September to October) to allow roots to establish before winter sets in.
Ideal Growing Conditions:
- Sunlight: Peonies prefer full sun but can tolerate partial shade, especially in hotter regions of Minnesota.
- Soil Quality: Plant peonies in well-drained soil enriched with organic matter. Avoid heavy clay soils by amending with compost or peat moss.
Planting and Establishment:
- Depth: Plant peony tubers (or roots) 1-2 inches below the soil surface, with eyes (buds) facing upwards.
- Spacing: Space peonies 3-4 feet apart to allow for ample airflow and prevent overcrowding.
Watering and Maintenance:
- Watering: Provide regular watering, especially during dry spells in spring and summer. Aim to keep the soil consistently moist but not waterlogged.
- Mulching: Apply a layer of organic mulch (e.g., shredded bark or compost) around peonies to conserve moisture and suppress weeds.

Fertilizing:
- Spring Feeding: Apply a balanced fertilizer (e.g., 10-10-10) in early spring before new growth emerges to promote healthy foliage and blooming.
- Avoid Over-fertilization: Peonies are sensitive to excessive nitrogen. Avoid high-nitrogen fertilizers that can promote lush foliage at the expense of flowers.
Supporting and Pruning:
- Staking: Provide support (e.g., peony cages or stakes) for taller peony varieties to prevent flopping under the weight of blooms.
- Deadheading: Remove spent flowers to promote continuous blooming and prevent seed formation. Cut back flower stalks to the base after flowering.
Winter Protection:
- Mulching: Apply a layer of mulch (e.g., straw or shredded leaves) around peony plants in late fall to insulate roots and protect against frost heaving.
- Snow Cover: Snow acts as a natural insulator. Allow snow to accumulate around peony plants to provide additional protection during winter.
Pest and Disease Management:
- Common Pests: Watch for signs of aphids or botrytis blight. Treat infestations promptly with insecticidal soap or fungicides as needed.
- Good Air Circulation: Prune back neighboring plants to improve air circulation and reduce risk of fungal diseases.
Dividing and Transplanting:
- Timing: Divide peonies every 4-5 years in early fall to rejuvenate plants and promote vigorous growth.
- Method: Dig up clumps of peony roots, separate into smaller divisions with at least 3-5 eyes, and replant in prepared soil.
