The peony has the fattest, most delicious petals and rich green foliage, making it outrageously attractive when it is in bloom. From spring to summer, savor stunning floral displays. Learn how to care for, grow, and plant peony.
About Peonies
Peonies are a perennial that will steal your breath away every year. The plants may even outlive you—some have been reported to survive for at least a century.
When Is Peony Season? When Do Peonies Bloom?
Depending on your location and the kind you are planting, peonies bloom from late spring to early summer.
You may extend the peony season across several weeks and take use of those magnificent blossoms for as long as possible thanks to the abundance of nurseries that provide early, midseason, and late blooming types.
Peonies may thrive as far south as Zones 7 and 8, and they are hardy to Zone 3. The key to success in the majority of the United States is to provide full light and well-drained soil. Peonies even enjoy the winter’s coldness because it helps their buds grow.
Types of Peony Flowers
You can pick from six different varieties of peony flowers: anemone, single, Japanese, semi-double, double, and bomb. The odors of different plants also differ; some, like “Festiva Maxima” and “Duchesse de Nemours,” have seductive rose-like aromas, while others have a lemony scent or none at all.
Where to Plant Peonies
When planted as a low hedge or along sidewalks, peonies make excellent sentinels. As majestic and dignified as any flowering shrub, the peony’s bushy cluster of attractive glossy green leaves lasts all summer before turning purplish-red or gold in the fall.
Peonies work nicely with irises and roses in mixed borders and blossom alongside columbines, baptisias, and veronicas. Plant pink peonies with blue Nepeta or violets, then surround white peonies with yellow irises and a froth of forget-me-nots.
Peonies are not overly picky, but you should pick your place carefully because they dislike disruption and do not transplant well.
Although they can survive in partial shade, peonies like full sun, and they flower at their best in an area that receives 6 to 8 hours of sunlight per day.
Because of its huge flowers, peonies can become top-heavy in severe winds. Therefore, provide shelter. (If necessary, stakes can be used to hold them up.) Planting too close to trees or bushes will cause peony to compete with them for nutrients, sunlight, and moisture.
Grow peony in rich, wet, humus-rich soil that is deep, fertile, and well-draining. pH in the soil should be neutral.
When to Plant Peonies
As long as they are planted correctly and become established, peony plants require minimal upkeep. However, keep in mind that they do not adapt well to transplanting, so you should consider this when choosing your planting location.
- Plant peony in the fall: in the majority of the United States, in late September or early October, and even later in the fall in Zones 7 and 8. Your planting zone can be found here.
- If you need to move an established plant, the fall is the ideal season because the plant will be dormant.
- About six weeks before the ground freezes, peonies should be planted.
- While planting peonies in the spring is absolutely a possibility, the results aren’t always favorable. They often trail behind plants planted in the fall by roughly a year, according to experts.
How to Plant Peonies
- Peonies are typically offered as divisions of a 3- or 4-year-old plant, bare-root tubers with 3 to 5 eyes (buds).
- Peonies should be placed 3 to 4 feet apart to allow for enough air circulation. The development of disease can be facilitated by stagnant, damp air.
- In a sunny area, dig a generously sized hole that is about 2 feet deep and 2 feet wide. The inclusion of organic matter in the planting hole will improve the soil. Add additional compost to the soil to improve it if it’s sandy or heavy. Add about a cup of bonemeal to the ground. Find out more about soil improvements and getting the soil ready for planting.
- The roots should be positioned in the hole just 2 inches below the soil’s surface, with the root’s eyes facing upward on top of a mound of soil. Avoid planting too deeply! Choose early-blooming species, put them approximately 1 inch deep, and provide some shade in southern states.
- Backfill the hole after that, being careful to prevent soil settlement and a 2-inch root burying. Gently tamp the ground.
- Plant a container-grown peony no deeper than it was when it was in the pot.
- When planting, give everything plenty of water.
How to Care for Peonies
Young peony take time to develop, just like children. In order to establish themselves, blossom, and flourish, they typically require a few years. They eventually leave home on their own, fully grown and adjusted… No, that’s just kids, I suppose.
Peonies benefit from gentle neglect. They don’t require digging and dividing every few years like the majority of perennials do.
- Don’t use any fertilizer. Before planting, till the soil thoroughly while adding compost and a small amount of fertilizer.
- Early summer, after the peonies have flowered and you have deadheaded the blooms, is the ideal time to apply fertilizer (such as bonemeal, compost, or well-rotted manure) to a soil that is deficient in nutrients. Keep fertilizing to a few years at most.
- assist the stems Peonies’ stems, which occasionally are not strong enough to hold their enormous blossoms, are the only part of their structure that may be considered weak. Think of structures that allow the plant to grow through the middle of the support, like three-legged metal peony rings or wire tomato cages.
- Peony blossoms should be deadheaded as soon as they start to fade, cutting to a sturdy leaf so that the stem doesn’t protrude through the foliage. To prevent any infections from overwintering, trim the foliage to the ground in the fall.
- Avoid covering peonies with mulch. For the first winter following planting, you can VERY LOOSELY mulch with pine needles or shredded bark when the winters are bitterly cold. In the spring, get rid of the mulch.
Peonies bloom between late spring and early summer, but by planting a variety of cultivars, you may arrange your garden for a succession of blooms from mid-May to late June. Here are a few options:
- ‘Early Scout’ has red solitary flowers that open incredibly early.
- “Firelight”: very early-blooming, single, pale-pink flowers
- ‘Karl Rosenfield’: double, midseason bloomer with substantial crimson blooms
Intersectional Peonies
Proper planting depth is the most important consideration when planting peony. The crown of intersectional peonies should be buried between 112 and 2 inches below the surface of the soil. After planting the crown below soil level, the eyes may slightly protrude above the ground if they have already started to grow.
Garden Peonies
The right planting depth is the most important factor in cultivating peony. The eyes on the root of garden peony should be buried between 112 and 2 inches below the surface of the soil. To fit in the pot, the lower roots may need to be somewhat pruned. A good flowering performance is more likely to be achieved with proper planting.
Tree Peonies
Correct planting depth is the most important consideration when planting peony. When planting grafted tree peony, make sure the graft union is 4-6 inches below the surface of the soil. When the roots are pruned to fit in the pot, very little of the woody stem may remain above ground. The grafted plant will grow its own roots if it is planted properly, making it stronger overall.
Peonies have demonstrated for well over a century that they are stunning yet hardy, low maintenance perennials.
Is it possible to plant peonies too shallowly?
Growing Medium: We advise using any commercially available bark-based, well-drained soilless mix.
Planting Depth: The success of flowering depends largely on the planting depth. The eyes may fail to bloom if they are planted either too shallowly or too deeply. The most frequent cause of peonies not blooming is this, which is the most frequent error committed while planting peonies. The eyes must be buried between 11/2 and 2 inches beneath the soil surface.
Timing: Many growers are curious as to how late peonies can be effectively potted up. It’s never truly too late or too cold, said Renee Jaeger and Roy Klehm of Klehm’s Song Sparrow Farm and Nursery. The equilibrium between the air and soil temperatures must be preserved, as growers are aware.
When overwintering potted peony, it is ideal to do it in a covered building like a greenhouse or covered polyhouse. To become vernalized, they need 500 to 700 hours at 32 to 37 °F. The best course of action is to let them to adjust to outdoor temps gradually after that. Please be advised that peonies sent after January 1 have already undergone vernalization.
Temperature: Peonies must be grown in a cool environment when vernalization is complete. The Klehm’s Song Sparrow suggests cool nights between 35–40°F and days between 45 and 50°F. On sunny days, it might be necessary to turn on the fans in the greenhouse to maintain this colder temperature. Higher temperatures cause the plants to develop their buds more slowly and the flowers to deteriorate more quickly.
Fertilizer: Klehm’s Song Sparrow advises applying a low rate fertilizer, such as 18-6-8 at 100-150ppm at every other watering, in the spring when they are potted up. Flowering may be hampered by overfertilization.
