Here’s How to Grow Peonies That Last Forever

Peonies are considered potentially poor performers in the Middle and Lower South, but there are secrets for helping them thrive. "Location is a big part of how well you'll do with peonies," says Rick Berry with Goodness Grows in Lexington, Georgia. "Here, we recommend partial shade, preferably with protection from afternoon sun." Peonies grown in full sun often suffer leaf scorch by midsummer. The plants go dormant early, preventing them from building up food preserves. This reduces flowering the next year. In filtered light, however, peony foliage continues growing into late summer or early fall, storing energy for the following year's blooms.

Peonies do not require fertilizer when planted in good soil. "If you consider the beautiful ones you see in cemeteries, plants that have been there 30 years with virtually no attention, you realize that they do just fine without supplemental feeding," Greg says. However, in many parts of the South, gardeners are faced with heavy, clay-based soil, which lacks the necessary nutrition. In these areas, apply Holland Bulb Booster after bloom, following the directions to prevent overfeeding.

Soil preparation is important–peonies falter in wet conditions. They don't want to be in soil that holds moisture. So dig a large, wide hole and amend the soil with leaf mold or soil conditioner, which is available at garden shops. To plant, mound the improved soil inside the hole. Then place the roots with the eyes just below the soil surface, facing up. This ensures adequate drainage and aids winter cooling.

The selection you choose may determine how well your peony blooms. There are also some really beautiful doubles that do well, but they should be the early kinds too. Many Southern gardeners believe the single varieties perform best in warmer regions. Dependable peony selections include ‘Festiva Maxima,' ‘Paula Fay,' ‘Bowl of Beauty,' and ‘Kansas."

When you order by mail, the plant you receive will be bare root. This means it is not actively growing and not planted in soil. "Order your peonies in spring, when you can see what blooms on plants in your area look like. You shouldn't receive your peony until fall when it is shipped dormant. If planted immediately, the peony will resume a normal growth cycle in its new home. If you plant peonies in the spring, avoid bare-root plants. Instead, look to garden centers and nurseries where you will find them already growing in large containers.

"They say you should plant a peony for life," Greg says. "What that means is that a peony will easily live for 50 years. It doesn't mean you can't move it." The time to relocate a plant is late fall, when it's dormant. After the foliage has died down, dig a wide ring around the plant, and carefully lift the roots. Replant it as you would a new peony. "Have patience. It may take several years to become established and bloom well," Rick says.
