Peonies grow in colder climates and need at least a month of temperatures below 40 degrees Fahrenheit. In southern Georgia, peonies generally do not grow and in central Georgia, peonies may grow, depending on variety and weather conditions. North Georgia, however, is the perfect environment to grow peonies, which are perennial plants best planted in the fall during their dormant stage.
Choose a location in a partially shady location that receives at least six hours of sunlight. In north Georgia, avoid a location on the south side of a solid structure that will be too warm for peonies. Remember that peonies need at least one month of temperatures below 40 degrees Fahrenheit and the south side of solid structures tends to be warmer than other areas of the yard.
Prepare a planting bed a week before planting. Turn over the soil to a depth of 12 inches. Mix in several inches of organic matter, such as compost or peat moss. Then water the soil so it will settle before planting.
Dig holes so that they are twice as wide and just as deep as the peony's current container. Take the peonies out of their containers and set them in the holes. If you planting just the bare roots, plant them with the eyes facing up and only 1 to 2 inches beneath the soil.
Backfill the soil and pack down the soil lightly. Water with a couple inches of water and mulch with organic mulch, such as bark or wood chips.
Take the mulch off in the spring and leave them alone. Rain is usually sufficient unless there are drought-like conditions. In that case, water them an inch or so once a week during the growing season.
Cut off the foliage in the fall. If you don't, your peonies may become diseased.
