Peony plants should be regarded as a permanent addition to your landscape, similar to planting a tree, because they thrive for decades. Flowers will last for years if they are planted properly.
Herbaceous peonies should be planted as bare-root plants in the fall or the earliest spring. These plants have compact rhizomes with thick, fleshy roots and several “eyes” (growth buds). Almost all tree peonies are grafted onto herbaceous peony roots, although they can also be bought bare-root and planted in the fall or spring. Many producers do provide container-grown tree peony too, which may be planted outside whenever the ground isn’t frozen.
Select a location that is sunny, well-drained, and clear of competing tree and shrub roots. Dig a space 1122 feet broad for each rhizome, turning the soil to a depth of at least 1 foot while loosening it. Work in a ton of organic material, such as yard compost, manure that has been composted, or chopped leaves to which you have added a cup of superphosphate.
Roots of herbaceous peonies should be planted such that their eyes are exactly one inch below the soil’s surface; otherwise, flowering may be hampered. A minimum of three eyes should be present on each rhizome; those with fewer eyes bloom more slowly. Tree peony should be planted with the graft line 34 inches below the soil’s surface (the object is to get the shrubby top to root on its own). Mulch peonies in the spring to keep the soil moist and to cool the roots. Be patient because plants typically don’t bloom their first year.
After their initial season, peonies should bloom every year if fertilized twice a year. Use a low-nitrogen fertilizer, such as 5-10-10, to feed plants. In the spring, when the shoots are starting to sprout, sprinkle about 1/2 cup around mature plants. Around new, immature plants, cut back to 1/4 cup. repeat in autumn. As an alternative, before mulching in the spring, top dress with an inch of compost; repeat in the fall.
It’s good to know that deer don’t often eat peonies. Botrytis, a fungus-related illness, does, however, occasionally manifest itself in cool, moist conditions. Stems wilt and collapse, flower buds turn black, and they fail to open. Make sure there is enough airflow around the plants, tidy up the garden in the fall, and get rid of any old mulch and fallen peony leaves to avoid the issue. Spread fresh mulch and apply a copper fungicide to it as soon as new growth appears in the spring.
Use branches left over from trimming to support stems as buds start to swell and become top heavy. To support the heavy blooms, especially during spring rains, plant them in the soil.
Peony flowers should be cut just as the buds start to open if you want to use them for bouquets. Don’t cut more than half the blossoms from each clump, and leave at least three leaves on each stem you cut. By doing this, enough leaf surface is preserved to create food stores for the following year. Future blossoming is also aided by promptly removing wasted flowers before they set seed.
Poor flowering can be caused by a variety of factors, such as the following: the plant is too young (wait awhile); the planting depth is incorrect (lift during the dormant season and plant at the proper depth); the flower buds were killed by a late freeze (wait until the following year); the location is too shady (move to a sunnier spot during dormancy); the weather was too hot too soon (plant early-flowering types); the plant has a nutrient defic (leave it alone).
When should peony be planted?
- 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).

Where should peony bushes be planted?
A gardener’s dream come true are peonies! Their lavish blooms, striking leaves, enticing aroma, and stunning beauty have made them beloved. Even though they hardly ever bloom in the first year after planting, when they do, they provide a lifetime’s worth of lovely flowers. Where should I plant peonies to get a lot of blooms, you might be asking yourself.
Peonies prefer direct sunlight and thrive in warm, sunny environments. As peonies don’t like to compete with other plants for sunshine, nutrients, or moisture, be sure to plant the flowers far from towering trees or dense shrubs. They need to be cultivated in rich, wet, deep soil that drains properly.
The sole purpose of this page is to discuss peony growing circumstances, with a particular emphasis on where to plant them, how much sun (or shade) they need, the best type of soil, what plants or flowers work well as companions, and whether or not they are simple to cultivate. So let’s get started if you’re eager to learn more about where to plant peonies!
Do peony grow in South Carolina?
There are several flower varieties and colors. Peonies frequently do poorly in the lower South because they need a winter chilling period to go into dormancy. Early flowering, solitary, or Japanese cultivars typically outperform other varieties in South Carolina.
Can peony thrive in warm weather?

What’s fresh: Herbaceous and tree peonies are crossed to create itoh hybrids, also known as intersectional hybrids. They can reach a height of 3 1/2 feet, produce flowers in lavender, pink, copper, yellow, or cream, and bloom for a longer period of time than typical herbaceous varieties.
Since their stems are more thicker and more sturdy than those of herbaceous species, they are effective in supporting large cups of petals.
Where to grow: Peonies do best in cooler regions (Sunset zones 111; A1A3), where the winters are particularly chilly. However, some will thrive in warmer environments (see list below). Under zones 1420, all are worthwhile attempts in dappled shade. There, give the plants plenty of water and midday shade.
When to plant: In late April in warmer climates, plant container-grown plants; in May or June in colder climates. In 5-gallon containers, 3-year-old peony should blossom more.
Spring or fall, from containers used for nurseries: Place the plant in the ground with the top of its rootball level with the dirt after loosening the soil and adding copious amounts of compost, being careful not to disturb the plant’s delicate feeder roots. Or move it into a sizable (18 to 24-inch diameter) container that is deeper on the outside than the inside.
Plant herbaceous peony roots with eyes 2 inches deep in cold climates and 1 inch deep in warmer climates in the fall. In cold climates, itoh hybrids should be planted 3 inches deep; in warmer climates, 2 inches deep.
How to feed and water: Water frequently. When the first leaves emerge in the spring, fertilize with a low-nitrogen fertilizer (such 5-10-10) and then once more when the final flower has faded.
When to pick: Cut stems just as flower buds start to open to harvest blossoms for bouquets; leave at least three leaves on the plant to feed it for the following year. Blooms will keep for up to a week in vases. Although Itoh hybrids generate more flowers per stem as the plants become older, the majority of cultivars only produce one bloom per stem.
After flowering, prune down herbaceous and Itoh hybrid peonies in the fall; fresh growth will appear in the spring.
Grab a peony.
For cold climates, pick: There are three new Itoh hybrids—crosses between tree peony and herbaceous peonies—called “Bartzella,” “Pink Double Dandy,” and “Yellow Doodle Dandy.” Bartzella has unusually enormous, bright yellow blooms.
Four herbaceous favorites for cool or warm climates include “Blaze,” a vivid red single, “Festiva Maxima,” a white double with crimson flecks in the middle, “Sarah Bernhardt,” or “Sea Shell” (satiny pink single).
Shop: Purchase plants (itoh hybrids can cost up to $100 at nurseries, while ordinary herbaceous can cost $40), beginning in late April in warm climates and May in chilly ones. Plants that are three years old and are housed in five-gallon containers will reliably blossom.
Visit and purchase: The 200 or so varieties of herbaceous and tree peonies at Chateau CharMarron Peony Gardens (5335 Sierra Rd., San Jose; 408/251-7048) begin flowering in late March and last through June.
