In Michigan, When Do You Plant Peonies?

In Michigan, the best time to plant peonies is from late summer to early fall, specifically late August to late September. The ideal time for planting peonies is between September and October, as it allows roots to establish before the ground freezes over. The W.E. Upjohn Peony Garden has been a beloved attraction in Michigan, drawing visitors on an annual spring pilgrimage.

Planting peonies in the fall or spring ensures they will take full sunlight, but can tolerate moderate amounts of shade. Planting peonies away from trees and shrubbery that compete for water and nutrients is essential for their success. In September, the best time to divide existing plants or plant newly acquired roots is in the fall. Peonies do best in full sun but can tolerate some shade. Stakes are often necessary to hold up the plants.

Fecturing peonies well is crucial for their growth and success. Fertilize peonies once a year, especially in the spring while they are actively growing. Cut back foliage and wait until after the last frost date passes for leaves. Peonies are flowering perennials best planted in autumn for their beautiful flowers that bloom from spring to summer.

Dividing mature plants is the best time for propagation, and peony roots should be cut 2-3 weeks before the last frost-free date. Nurseries and other resources can help guide you through the process of planting peonies in Michigan.
