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.

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
Are peony rooted shallowly?
Herbaceous peonies (paeonia) in bloom provide the best floral display in any garden. Long-living perennials, they provide excellent cut flowers, and after they have finished flowering, their leaves makes for a lovely backdrop for other plants for the remainder of the growing season.
There are numerous varieties of peony blossoms, including bomb, double, single, semi-double, and Japanese. The majority of plants grow to a height of two to four feet then die back in the late fall. They come in a wide variety of hues and can be planted to bloom one after the other for a lengthy season of eye-catching flowers. Some peonies have a beautiful scent as well.
In zones 3–8, herbaceous peonies are a reasonably simple plant to grow. They can be cultivated safely in zone 2 if there is adequate snow cover. To flower, they need temperatures between 32 and 40 °F for at least 20 to 40 days. Although occasionally offered as potted plants, they are more frequently bought as bare roots. The best chance to get a plant that blooms the first year is to buy them from a trustworthy supplier. To allow bare root peony time to grow roots before winter sets in, they are planted in the early fall. If you buy a potted plant, you should plant it in the first few weeks of spring.
A particular species of herbaceous peony is called a fern leaf peony. The leaf is delicate and needle-like, resembling fern in appearance. They typically grow to a height of 16 inches and bloom early in the growing season. Compared to most herbaceous peony, they go dormant and start to die back much early.
Herbaceous peony typically survive about 30 years, while some have been known to reach 100 years old! Choose a spot where they will receive at least six hours of sun each day and won’t be disturbed for a long time, considering how long they live. They will benefit from a little midday shade if you reside in a region with particularly scorching summers. They may not flower if placed in excessive shade, and they are more vulnerable to disease. They dislike sitting in water, so make sure there is excellent drainage.
Plan ahead and get your planting area ready. Create a hole that is 12 to 24 inches wide and 18 inches deep. The soil you take from the pit should be mixed with rich compost or well-rotted manure. You may probably need more additions to improve sandy or clay soil. Refill the hole with the majority of the modified dirt. The eyes and tip of peony roots are planted with their tips facing upward. When you’re done planting, the eyes should be no closer than 2 inches from the soil’s surface. Any deeper planting may prevent blooms from blooming. The tops of the eyeballs could freeze and perish if the seed is planted too shallowly. Backfill the remaining soil and thoroughly hydrate it. Although they will benefit from routine watering in their first year, once established, they are extremely drought tolerant. Avoid watering flowers from above as the water might make them heavier and cause them to bend or shatter. Place peonies three to four feet apart if you wish to plant more than one.
Peonies typically grow in neglect, so if you put them in healthy, nourishing soil, they shouldn’t require any fertilizer for many years. They will instead develop leaves if too much fertilizer is applied, not flowers. Composting your gardens or soaking the roots in fish emulsion are the greatest ways to keep them content. The nutrients will be washed away more quickly in particularly porous soil, so you might want to use a slow-release fertilizer. Because they are bottom feeders, you should avoid applying fertilizer to the crowns. You can cover the area where the roots develop by spreading it 6 to 18 inches out from the crown.
Keep in mind that peonies have weak roots while weeding them. You risk damaging the roots if you cultivate deeper than 2 inches.
Peonies sometimes flop over in rainy or windy weather because they are extremely tall and have huge flowers for the most part. Staking your plants is the easiest approach to avoid this. As soon as they emerge from the ground, you should install your supports since they develop quickly. Although there are rings or hoops designed expressly to support peony, they are occasionally excessively short. Although effective, tomato cages could not be wide enough. Stakes can be inserted into the ground around the outside of the plants, and twine can be used to support a grid pattern. Use your creativity to come up with as many innovative solutions as you can.
What are the ants, which you frequently notice on your peony buds, doing? They are eating. Ants enjoy the sweet nectar that the flower buds generate. Contrary to what you may have heard, they are not devouring the plant, and ants are not required to open the buds.
Your peony could occasionally not blossom. There are a number of causes for this, including planting too deeply, overcrowding of other plants for nutrients, plants that are still very little, excessive shade, excessively hot weather, late frost damage, poorly draining soil, and disease.
Providing your plants with adequate air circulation and clearing away plant waste are the greatest ways to prevent disease. Botrytis, which causes new stems to wilt and die while young buds turn black, bud blast, a fungus that causes blackened and dried-out buds, and powdery mildew can all harm peonies (powdery white patches that cause leaves to turn yellow and drop, stunted growth, distorted buds and blooms, and weakness in the entire plant). All of these, with the exception of bud explosion, are generally treatable. In addition, there is a fungus known as Cladosporium, also known as peony measles. Small red dots start out and grow to be substantial dark spots. Although not lethal, this is not appealing. Just be careful to clean up your garden during the fall season. Fortunately, peony do not attract deer.
Herbaceous peonies should be cut down to 2 inches above the ground in the fall, after the stems have dried up or after the first freeze, and the garden’s debris should be cleared away to avoid illness. Early foliage pruning can potentially have an impact on your plant’s ability to blossom. Following the ground freezes in the first winter after planting, it’s a good idea to mulch with 3–4 inches of mulch.
Include a handful of these regal plants in your garden design when planning it this year. To include and appreciate the beauty of these long-lived plants, it is well worth the effort to dig a new garden if there isn’t enough space in your current one.
How is a peony tree dug up?
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.
