Peonies are enduring garden favorites that are well-known for their lavish, early-summer blossoms. They are dependable plants that bloom for generations with little care and have an extraordinarily long lifespan. Peonies are unmatched as cut flowers. They are beautiful in their natural beauty and have a soft, enduring perfume, whether they are grown alone or in mixed bouquets.
Start with a Better Bulb
It’s simple to discern quality differences between two peony plants when you compare them side by side. Grade #1 peony, as displayed at far left, are provided by Longfield Gardens. Right on this page is a peony of grade #2. The larger root requires less time to mature into a robust plant that bears several blossoms.
Plan for Success
Peonies are low maintenance and incredibly simple to grow. Here are some pointers to assist you achieve the greatest outcomes.
Peonies thrive in the sun and perform at their best when they receive at least 6 hours of direct sunlight each day. It is preferable to put your peonies in the most sunny area possible because the more sun they receive, the better their blooms will be.
Zones 3–8 are suitable for peonies’ winter hardiness. Cold winter climates are excellent for their growth and flowering. Zones 8 may be difficult for them, while zones 9 and warmer are not advised for them. Check your hardiness zone now. The USDA Hardiness zone map can be found here.
Soil: Loose, fertile, well-drained soil is ideal for growing most plants, including peony. By incorporating compost and an all-purpose fertilizer during planting time, you can enhance the condition of your soil. Planting should not be done on wet or compacted soil.
When to Plant: Spring or fall are both suitable times to plant bareroot peonies. The plants can withstand frost, so you can plant them two to three weeks before the last day of frost. You can plant potted peonies at any time of the growing season.
How to Plant Peonies
Make a 12-by-12-inch hole. Compost and general-purpose granular fertilizer should be added after loosening the soil at the bottom of the hole (follow package directions).
Place the peony root in the hole with the eyes (the growth points) no lower than one inch below the surface of the soil. Peonies that are planted too deeply may continue to grow but not blossom. Add soil over the root and water as necessary.
Planting Tips for Peonies
Peonies need full sun in order to produce a profusion of blossoms. Even though certain types may withstand moderate shadow, fewer flowers bloom in general when there is less light.
Peonies should be planted in soil that is fertile, well-drained, and has a pH range of neutral to slightly alkaline. They will eventually grow a substantial root system and become challenging to relocate. Spend some time placing your peonies in a location where they can flourish for many years. The plants are reasonably drought resistant once they are established.
Where to Plant Peonies
Continual Gardens Perennial gardens work well with peonies. Their year-round gorgeous dark green leaves. Peony leaves occasionally turn crimson or gold in the fall.
Fence lines and hedges To create a low hedge for enclosing a space, defining one side of a garden, or edging a walkway, peonies can be planted in a row. They also look fantastic when planted at the bottom of a chain link or split rail fence. As a sturdy fence will restrict airflow around the plants and increase their susceptibility to foliar diseases, avoid growing them next to one.
Plantings for the foundation and shrub borders The presence of a peony is comparable to that of a tiny shrub. Peonies may grow practically anyplace in your landscape as long as they are planted in well-drained soil, receive enough light, and have sufficient air circulation.
What to Expect from Peonies
All peonies bloom in the first few weeks of summer, however each cultivar blooms at a different period. The peony season can be prolonged by a month or more if you plant a mixture of early, mid, and late season bloomers. Other early summer perennials like iris, alliums, and roses pair well with peonies. The greenery keeps borders looking full and gives other flowers a lush background.
Most peony mature at least three feet tall and three feet wide, depending on the type. Therefore, it’s crucial to provide them freedom to expand. Peonies will maintain their flowers straight if a support cage is placed all around them. Use a pre-made peony support or create your own from steel or mesh reinforcing wire or wood slats. Early in the spring, before the plants reach a height of 12 inches, supports should be installed.
Carefree peony plants that hardly ever experience insect or disease problems. A young peony plant needs two to three years to become established, but once it does, it will reliably blossom each year.
Fantastic cut flowers are peonies. The majority of cultivars are also incredibly fragrant, and they remain for days in a vase. When the buds are in the “marshmellow” stage, peony stems can be removed and kept in water in the refrigerator for a few weeks. After many days, the buds on the stems brought into room temperature will begin to open.
Caring for Peonies are they Bloom
Use scissors to cut off the wasted flower heads and the top six to eight stems once the blossoms have faded “that stem. This will prevent the plants from forming seed heads and keep the plants looking tidy. The plants will be able to produce the energy they require for the blossoms of the following year if as little foliage as possible is removed.
When the leaves start to turn yellow in the fall, trim all the stems to within an inch or two of the ground.
When the stems are about 6 inches long in the spring, fertilize peonies “tall. Around the base of each plant, dispense roughly a half cup of all-purpose granular fertilizer. To avoid having the eyes buried too deeply, remove any mulch or other debris from the plant’s crown.
How to Divide a Peony
Peonies can stay undisturbed for several years in the same location. If the plants must be moved, do so in the fall when they are beginning to enter dormancy rather than in the spring when they are just starting to grow again. Trim the leaves, which may be up to three feet wide, then carefully remove the entire root ball. Dig carefully, avoiding uprooting any roots, and dig deeply. Replant right away, and give it lots of water.
Plant division can be done in the fall or very early in the spring. One method is to remove the entire root ball as previously said, then place the clump on a tarp. After cutting the clump into sections with a sharp knife, quickly replant each section. Work swiftly and gently, causing the fewest potential injuries to the fleshy roots.
The alternative is to cut one or more portions of root from the mother plant using a sharp spade. Once more, plant these divisions again right away, and during the first growth season, irrigate as necessary. Though you may often anticipate losing at least one season of blossoms, plants will recover more quickly the less the roots are touched.
Peony Pests and Diseases
Pests and illnesses rarely affect peonies. Buds can occasionally become black and shrivel as if they have been scorched by a fungus called botrytis. Young shoots and entire stems may turn black as a result of the disease. Wet weather worsens infection, as it does with all fungus-related illnesses. Take away and discard any tissues that are harmed. The greatest method of management is prevention; discard wasted blooms as soon as you can, abstain from overhead irrigation, and avoid crowding plants to promote good air circulation.
Peony buds are coated in a slightly sweet, sticky material just before they blossom. This will frequently draw ants, who enjoy the tasty treat. The ants are not necessary for peonies, yet they do not harm them in any way. It benefits both parties. Simply shake the flowers or submerge them in cool water if you plan to cut them and don’t want to attract ants into your house.
What happens if peony bulbs are planted in the spring?
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.
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.
- 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
What is a Bare Root Peony?
A bare root peony division is one that removes the soil from a peony plant that has been dug up and divided in the fall (for propagation reasons).
Will My Peonies Bloom the First Year?
Peonies need 3 to 4 years to establish themselves as a fully mature blooming plant, as opposed to annuals. The first year of growth is dedicated to producing roots and establishing the plant in the garden. First-year flowers could be smaller and lack the normal shape or color of a mature plant. In fact, the first or second year some peony may not even blossom. By the third year, there will be a profusion of blossoms, which will be a fantastic reward for patience. “The First Year They Sleep, The Second Year They Creep, and the Third Year They Leap,” goes the proverb concerning peony.
Why are My Peonies Not Blooming?
More than “They were planted too deep,” there are numerous other reasons why peonies do not blossom. Before a rational explanation for why a plant has failed to blossom can be drawn, many questions must be asked.
Young plants could not have a strong enough root system or enough food reserves to blossom.
Compared to most domestically grown plants, imported roots are substantially smaller. For smaller roots to develop a suitable root system with enough food stores to create a bloom, they may need to grow for a few more years. A good peony root should contain at least three comparable roots measuring four to six inches in length and an inch in thickness, as well as three to five “eyes” (dormant buds) for growth.
Frequently, a peony that was planted at the same time as the rest of the groomed yard is now shaded by much larger trees. To bloom successfully, peonies require a minimum of eight hours of sunlight.
In the spring, when there has been a lot of rain and there is a lot of humidity, a fungus can damage tender new growth with forming flower buds. The disease’s symptoms show on pea-sized immature flower buds; these flower buds fail to develop and appear dark or blackened on the terminals of fresh growth. Plantings in their first and second years are more prone to this illness. The best way to control illness is still to cut back and remove peony foliage in the fall.
At the base of each stem, peonies generate latent buds in August that are referred to as “eyes.” These dormant “eyes” should be placed 1 1/2″ to 2″ below the soil’s surface in order to create a peony bush the following spring. In the fall, carefully scrape the soil around a few stems to measure the depth of the young ‘eyes’ at the base of each stem if you are unsure of the planting depth of an established bush. In our fields, we plant thousands of roots each fall without first gauging planting depth as we drop them into a furrow, thus it is rare for a peony bush to be planted too deeply and be the cause of a dearth of blooms. By developing dormant eyes at the correct depth as they mature, roots often self-correct the depth at which they were planted. Too frequently, hasty counsel is provided, and peonies are pulled out and replanted without understanding that disturbed peonies frequently suffer setbacks and repeatedly delayed blooms. Once planted, peonies perform best when left alone.
Do Peonies Ever Have to be Divided?
One of the longest-living perennials is the peony. If cultivated in rich organic soil with proper drainage and a location with eight or more hours of sunlight per day, peonies frequently live for fifty to one hundred years without ever needing to be divided.
Are All Peonies Fragrant?
Sadly, not all peonies have a strong fragrance. Red blooming cultivars typically have less fragrance than pink and white blossoming ones. All hybrid kinds besides the yellow Itoh (Intersectional) Hybrids lack scent.
Are Ants Needed to Open Blossoms?
There is no truth to the tale that has been passed down through the years. Ants are drawn to the sugar on flower buds in the same way that they are to picnic treats. Our fields have very few ants but an abundance of blossoms every year.
When is the Best Time to Cut Peonies for Arrangements?
early in the morning, before buds enlarge and open. When the flower bud is in the “marshmallow” stage, when it feels soft to the touch, cut the stems. Cut double flowering plants when they are about a quarter open. The bloom’s vase life will be shorter the more fully opened it is.
Why do my Peony Plants Fall Over After a Rain?
After a significant downpour, double flowering types are typically affected by this issue. Large flowers merely trap the rain, become overburdened by it, and collapse. Japanese and single types, along with more compact kinds with thicker stems, stay up better during rain. Peonies cultivated in semi-shade also have weaker, thinner stems than those grown in full sun.
Do Peonies Need to be Mulched for Winter Protection?
To avoid frost from heaving roots out of the soil, we advise mulching first-year plantings as the earth begins to freeze. Once established, the majority of peony are quite resilient and never require mulching, while hybrids can be harmed by a winter with no snow cover. A good winter mulch is advised for hybrids in harsh environments, such as regions where the temperature is frequently below zero degrees Fahrenheit.
