Indiana's State Flower Location Peonies grow best in a protected sunny site. Choose an area that receives at least six hours of sun a day and is protected from strong winds. Peonies like good air circulation. Space them 3-4 feet apart. Do not plant too close to competing trees or large shrubs.
Peonies can remain in the same place for many years, so choose the location carefully.
Site Preparation Peonies prefer a rich, moist, well-drained soil. Work the soil to a depth of at least 12-18 inches and add organic matter such as composted manure or sphagnum peat. If drainage is a problem, consider creating a raised bed. Planting Bare root peonies can be planted anytime in the fall until the ground is frozen. If the roots appear dry, soak them in a bucket of water for several hours.
