The optimum time to plant peonies is in the fall, any time between late September and early December. When purchasing a potted plant in the spring or summer, it is better to wait until fall to transplant the plant. To ensure good drainage, you can temporarily bury the entire pot where it will be planted, covering the soil beneath it with a few inches of gravel.
Follow these planting instructions in the fall:
Make a deep hole that is at least 24″ wide and 18″ deep. Rich, humus-rich soil as well as a lot of compost, composted manure, or peat moss should be used to fill the hole’s bottom.
Remove the plant from its pot with care, being sure to untangle any circling or tangled roots.
Place it there and backfill the hole with the same soil mixture as you go. When planting is finished, make sure the top of the plant’s bud “eyes” is no lower than 2 inches below the top soil level, taking into consideration any additional mulch layer you’ll add.

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

One of the toughest perennials for gardens is the peony. Every spring, they create luxuriant floral displays. These beloved perennials come in a wide variety of hues. Peonies come in a variety of colors, including white, yellow, pink, red, and others.
Every peony prefers full sun and soil that drains properly. If they are planted in an area with poorly drained soil or are crowded, they are vulnerable to fungus disease.
There are several variations of each of the three basic types of peony. Herbaceous peonies usually reach heights of 2 to 4 feet. They grow in the landscape as a shrubby mound with attractive flowers and dark green foliage. The blossoms emerge during the transitional period from spring to summer. Herbaceous peonies typically make a statement when spring bulb flowers are starting to fade and before summer perennials get going. Typically, flowers survive a week to ten days. The blossom festival can be extended to almost six weeks by combining a variety of early, mid, and late flowering cultivars.
Herbaceous peonies can live for 50 to 100 years on their own. They are a perennial that may add years of color to a garden.
Peonies that are herbaceous never require division. These long-lived plants flourish and blossom for years with little care if they are in the proper conditions. However, there is a misunderstanding that they cannot be parted. Nothing is more false than it is. Once they die back in the fall, peonies are simple to divide, and it’s a great way to create new plants. Just be certain that every division has three to five growth eyes (buds) in addition to three or more thick, strong roots. When replanting, pick a sunny spot with well-drained soil and add lots of compost to the planting hole and surrounding area. Make sure the buds are facing up and sticking just above the earth when you plant the divisions. If your new plants don’t blossom for a few years, don’t be disappointed.
Peonies don’t have a pressing need to flower and start a family because they can survive for over 100 years. Once they start flowering once more, they’ll keep putting on a show every spring for many years to come.
Tree peonies are a different variety of peony. The national flower of China is the tree peony. The spectacular flowers provide beauty and structure to the mixed border and can grow to be as large as dinner plates. The best part is that tree peonies can live incredibly long lives. In China, tree peonies have reportedly survived for more than 200 years. It goes without saying that appropriate planting and care are essential if you want your tree peony to enjoy a long life. Start by planting your herbaceous peony and tree peonies separately. As opposed to herbaceous peonies, which tend to bloom best when planted no deeper than when they were potted. However, because tree peonies are grafted onto herbaceous peony roots, they need to be planted much deeper. The purpose of the herbaceous roots is to give the tree peony stems enough time to establish roots before they rot.
Since the herbaceous root stock will survive and a never-ending stream of herbaceous peony suckers will grow into your tree peony, tree peonies should be planted so the graft is 4 to 6 inches below the soil surface. Tree peony don’t like to compete, so they should be planted in an area with plenty of space, direct sunlight, and well-drained soil. Add a cup of organic flower food and a half-handful of bone meal to the planting hole. Work a cup of alfalfa meal around the drip line right after planting and then every April after that to promote blooming. When determining where to put your tree peony, be selective. They dislike being transplanted after being established. Then, have patience, as it might easily take 3 to 5 years before it starts to bloom. That doesn’t seem like a long time to wait, especially because you’ll be able to enjoy blossoms every year for the following 200 years. Don’t be afraid to prune your tree peony if it is growing too tall, is too thin and lanky, or simply won’t branch out. Spend some time on the project. No more than one or two branches should be trimmed each year. The trimming can be done in the spring before growth begins, but it also works well if you do it right away after the blooming season is through. Naturally, there is no assurance that it will benefit your peony. Remember that we learn from our mistakes and that the best plant experts are those who have killed the most plants if my advice kills your pricey plant.
Peony blooms are excellent cut flowers, but if you intend to use them in centerpiece bouquets at a dinner party, you should rinse them off with the hose before bringing them inside. Nothing will make you feel worse than if your dinner guests find unwelcome guests hiding among their plate of brussels sprouts casserole! Ants that are drawn to a delicious substance on the buds frequently hide in the blooms.
When may peony in the Pacific Northwest be transplanted?
Peonies can be left in the garden unattended for a long time. But on occasion, it’s important to relocate established plants. To improve flowering, move peonies that are sheltered by tall trees or shrubs to a sunny location. The peony may need to be relocated in order to redesign a perennial bed or border. Plants that are large and robust can be dug up and divided for further growth.
The ideal month for transplanting established peonies is September. Cut the peony stems at or just above ground level to start. Next, thoroughly excavate each plant’s perimeter and its base. Keep as much of the root system as you can. Replant the peony right away in a sunny, well-drained area.
Large peony clumps must be divided in a number different ways. Shake the clump carefully to remove any loose soil from the root system after you’ve dug up the plant. Section off the cluster using a big knife. Each division needs to establish a strong root system and at least three to five buds (eyes). Smaller divisions will take longer to mature into beautiful plants.
The optimal conditions for peonies are full light and well-drained soil. Choose an area that receives at least six to eight hours of direct sun each day when choosing a planting site. Avoid standing in the shade next to big trees and plants. Compost, peat moss, or leaf mold used in significant quantities can typically improve poorly drained soils.
When planting a peony, make sure the hole is big enough to fit the plant’s root system comfortably. With the buds one to two inches below the soil’s surface, place the peony plant in the hole. (Peonies frequently don’t bloom successfully if the buds are deeper than two inches.) As you backfill the hole, compact the soil around the plant as you fill it with soil. then thoroughly rinse. Peonies should be spaced three to four feet apart.
Apply a four to six inch layer of mulch over the newly planted peonies in the late fall (mid-November to early December). Pine needles and weed-free straw are great mulching materials. Mulching keeps the soil from repeatedly freezing and thawing in the winter, which could lift the plants out of the ground. Early in the spring, before growth starts, remove the mulch.
Peonies that were transplanted might not bloom well the first spring. However, by the third or fourth year, the number of flowers should increase quickly.
