- Keep plants neat by deadheading and prune as needed (herbaceous only).
- When peonies become congested and produce fewer blooms, divide the plants.
- When the blossoms feel like soft marshmallows, cut the stems for bouquets. Water should contain Miracle-Gro for Fresh Cut Flowers.
When the peonies blossom, you can finally start to feel the arrival of summer. Around Memorial Day, when spring bulb flowers are starting to fade and summer blooms are beginning to emerge, these stunning perennials bloom profusely. Peonies are resistant to deer and rabbits, which is useful for gardeners who frequently experience issues with animals eating their plants. Peonies are frequently seen blooming despite years of neglect if you drive through old cemeteries or abandoned farmsteads. That is because to how simple peony are to grow!
How to Choose Peonies
Peonies come in four different varieties. They are forest peonies, tree peonies, herbaceous peonies, and intersectional peonies, in the order of blooming time. Herbaceous peonies, which thrive in zones 3–7, and tree peonies, which flourish in zones 3–9, are the two most popular varieties. Herbaceous plants often reach heights of two to three feet and spreads of two to four feet. With some types reaching heights of 7 feet, tree peony are more closely related to tiny shrubs. The type of peony you plant will depend on where you live and the style you’re going for because all peonies require similar maintenance. The focus of this paper will be on tree and herbaceous peony.
When to Plant Peonies
Fall is the ideal season to plant peonies. This is often when peonies purchased from a catalog will be delivered. It’s okay to plant peonies when you see them flowering and for sale in containers in the spring.
Where to Plant Peonies
Peonies require at least 6 to 8 hours of sunlight every day, though in zones 8 and 9, some shade from the sweltering afternoon sun is beneficial. Additionally, picking a location with sufficient air circulation is crucial to avoiding fungal illnesses.
How to Plant Peonies
In somewhat damp, well-drained soil, peonies thrive. Dig a hole, take the plant from the pot, and plant container-grown herbaceous peonies (the kind you buy in pots) so that the top of the root ball is level with the earth (any deeper and the peonies will not bloom). Fill up the area surrounding the plant by combining the discarded soil with an equal amount of Miracle-Gro Garden Soil for Flowers.
Before planting bare root herbaceous peonies, give them a brief dip in a basin of water to rehydrate them. Create a planting hole that is big enough to fit the roots, mix the soil as previously mentioned, and place a mound of the blended soil in the middle of the planting hole. Place the roots atop the mound and let them fan out and descend. Using the remaining blended soil, fill in the remaining portion of the hole, making sure that the “No more than 1 to 2 inches of soil should be present around the plant’s eyes (or growth buds) in order for it to bloom.
Deeper planting is required for tree peony. Unless they are grafted, peonies should be planted in the same soil combination as above, 2 to 4 inches deep at the crown (where the roots meet the stem). Check the label to see if the plant has been grafted, and then plant it such that the “The plant’s graft union, where the grafted top and rootstock are united, is located 4 to 6 inches below the soil line.
How to Stake Peonies
Peony stems are prone to toppling over after it rains, and the blossoms can become big and heavy. For herbaceous peonies, the best approach is to cover each plant in a peony cage in the spring, before the leaves begin to sprout (picture metal supports with rings for the flowers to grow up through). This is far more effective than attempting to hold each flower stalk separately, and it also looks nicer than wrapping the entire plant in string and cinching it in like a belt.
One stake can be used to stake tree peonies. Place the stake next to the stem in the ground, and then use a piece of twine to loosely secure the plant to the stake.
How to Water Peonies
When planting, give everything plenty of water. When the spring foliage begins to emerge and the flower buds start to show, give the plants another drink. Although peonies do not have a thirst, they will benefit from watering during dry spells for a year following the first planting.
How to Feed Peonies
Your peony will benefit from a powerful combination of care that includes excellent soil and the ideal plant food. Give peonies the nutrition they require by feeding them Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food in addition to the soil improvements indicated above for stunning color and more flowers than unfed plants. Peonies should be fed twice a year: the first time, right after they emerge in the spring (when the new shoots are 2 to 3 inches tall but before the flower buds are pea-sized), and the second time, in the middle of the growing season (about three months after the first feeding), to help them develop sturdy roots before the arrival of winter. Make sure you adhere to label instructions.
How to Help Prevent Problems with Peonies
Although mostly fuss-free, peonies occasionally experience fungal issues. Browning and failure to open flower buds are symptoms of botrytis. Brown patches on leaves are a symptom of some fungus illnesses. Infected blooms and leaves should be simply pruned off and disposed of (do not compost) in order to control these problems. Additionally, keep the plants neat, remove old foliage at the end of the season, and deadhead spent blooms. Peony blooms occasionally draw ants, but they won’t hurt the plants, so you can ignore them. (Contrary to popular belief, peonies do not require ants to blossom.)
How to Prune Peonies
Cut back each flower stalk on herbaceous peonies once all of the blooms have faded to just above a leaf, low enough so that the stem doesn’t protrude above the rest of the leaves. Unruly tree peony can be trimmed either in the spring or the fall (right before plants go dormant). However, any stems you trim back in the fall will not blossom the following spring (as you will be cutting off the flower buds). After blossoming in the spring, you can prune. Anytime you choose to prune, be careful not to take more than one-third of the plant with you.
How to Divide Peonies
It is ideal to leave tree peony alone (undivided) so they can flourish for many generations in the garden. If the clumps have become too large or the flowering has slowed, herbaceous peonies can be divided. Herbaceous peonies can be divided by digging up the entire clump and rinsing it off to reveal the plant’s numerous roots and eyes (or buds). Leave as least one large root and three to four eyes per clump after cutting the plant apart with clean, sharp pruners. Replant, adhering to the bare root peony planting directions above. The plants might or might not flower the first year after dividing, so keep that in mind.
How to Cut Peonies for Bouquets
Timing is crucial. Buds should feel roughly as firm as a soft marshmallow when squeezed, which is known as the “soft marshmallow stage.” Examining the bud’s coloration is another method for determining when to cut. The majority of the bud’s exterior should remain green, but you should be able to make out approximately half an inch of the flower’s vibrant petals. Although cutting the flowers at this point lessens the possibility of bringing ants inside with them, it is still advisable to inspect the flowers before bringing them inside. Plants should open up when stems are placed in a vase of water. For longer-lasting blooms, change the water every few days and apply Miracle-Gro for Fresh Cut Flowers (vs. water only).

Do peony grow quickly?
Growing peony from seed or grafted hybrid types are the two basic methods. Initially developing slowly, bush peony often start blooming three years after being planted. After being planted, bush peonies can live for up to 100 years. They develop slowly, producing progressively more blooms. Herbaceous peonies bloom their first year and then grow back from their roots the following year.
How high are peonies?
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.
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.
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.
Fertilize peonies in the spring when the stems are about 6″ 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.
