How to Grow Peony
Perennial
The peony (Paeonia) is a long-lived, cold-hardy perennial prized for its large, lush, often fragrant blooms in shades of white, pink, coral, and deep red. US gardeners love peonies because a single plant can thrive for decades with little fuss, returning reliably each spring and often outliving the gardener who planted it. Their old-fashioned charm and excellent cut-flower quality make them a favorite in borders and cottage gardens across most of the country.
Planting
Plant bare-root peony divisions in early fall, about six weeks before the ground freezes, so roots can settle before winter. Choose a spot with full sun, at least six hours a day, and rich, well-drained soil; peonies dislike soggy ground and heavy shade. Set the growing points, called eyes, no more than one to two inches below the soil surface, since planting too deep is the most common reason peonies fail to bloom. Space plants about three feet apart to allow good air movement and room to mature, and water them in well after planting.
Care
Water deeply during dry spells, especially in the first two years and while buds are forming, aiming for consistent moisture rather than frequent shallow watering. Feed lightly in spring as growth emerges and again after flowering with a balanced approach, and top-dress with compost each fall to build soil. Deadhead spent blooms to keep plants tidy and direct energy back to the roots, and stake tall or heavy double varieties before the buds open so rain does not flatten them. In late fall, after frost blackens the foliage, cut herbaceous stems down to the ground and remove the debris to reduce overwintering disease.
Bloom time
Peonies bloom in late spring to early summer, roughly May into June depending on your region and variety. Each plant flowers for about one to two weeks, though planting early, midseason, and late types can stretch the display over four to six weeks.
Garden uses
Peonies make outstanding cut flowers with a long vase life and are excellent as border anchors, informal hedges, or specimen plants. Their open blooms also draw bees and other pollinators to the spring garden.
Tips
Be patient, since newly planted peonies often take two to three years to hit their stride and may skip blooming the first spring. If a mature plant refuses to flower, the usual culprit is planting too deep, too much shade, or too little water, all of which are easy to correct. The ants often seen on peony buds are harmless and simply feeding on nectar, so there is no need to remove them.
