Double peonies bloom as a tight, rounded flower considerably different from a single peony bloom. Double blooms offer layers of flower petals rolled into a ball that resembles a snowball. This type of peony comes in a variety of colors ranging from pure white to bright red. Learning how to grow peonies requires standard gardening practices. This beautiful perennial will bloom year after year without need for transplanting or thinning.
Find a location suitable for your double peony plant. Choose an area with partial sun (six to eight hours each day) and with good drainage.
Add organic conditioners such as peat moss and compost to the soil when you turn over the garden in preparation for planting the peony.
Dig holes 12 inches deep and wide and about 3 feet apart to house the peony tubers. If you're working from a plant purchased at the store, you'll want to create a hole to accommodate the entire tuber ball. Choose plants that have at least three to four individual sprigs (also called eyes) since these plants will bloom the next season.
Sprinkle 1/2 cup of 10-10-10 fertilizer into the bottom of the planting holes. Replace about half the dirt in the hole.
Grasp the tuber in one hand and carefully examine the root. Locate any soft spots or dried areas that need removal. Simply cut the area out with a sharp knife, being careful not to remove too much of the tuber.
Place the double peony tuber into the hole, allowing for the eyes (small growths) to extend no more than 2 inches below the level soil surface. Backfill over the double peony tubers and press the soil down gently to remove air pockets.
Water the tubers thoroughly until the soil is damp but not saturated. Remember that everything your double peony needs to grow and thrive is contained in the tuber.
Things You Will Need

- Peonies frequently need staking during blooming time. Place the stake near the plant and secure it from the parent stems and along the flower stem. Make sure to use gardener's wire or lengths of cloth to prevent damage to the plant.
