Contrary to popular belief, peonies are lovely, classic cottage garden plants that do nicely in the right pots.
As with many other plants, peonies are large, robust plants, making it much simpler to grow them in beds or borders.
But growing peony in substantial pots is an alternative to think about if you have little to no permanent growing space.
How can you preserve peonies in a pot for the winter?
Growing Medium: We advise using any commercially available bark-based, well-drained soilless mix.
Planting Depth: The success of flowering depends largely on the planting depth. The eyes may fail to bloom if they are planted either too shallowly or too deeply. The most frequent cause of peonies not blooming is this, which is the most frequent error committed while planting peonies. The eyes must be buried between 11/2 and 2 inches beneath the soil surface.
Timing: Many growers are curious as to how late peonies can be effectively potted up. It’s never truly too late or too cold, said Renee Jaeger and Roy Klehm of Klehm’s Song Sparrow Farm and Nursery. The equilibrium between the air and soil temperatures must be preserved, as growers are aware.
When overwintering potted peony, it is ideal to do it in a covered building like a greenhouse or covered polyhouse. To become vernalized, they need 500 to 700 hours at 32 to 37 °F. The best course of action is to let them to adjust to outdoor temps gradually after that. Please be advised that peonies sent after January 1 have already undergone vernalization.
Temperature: Peonies must be grown in a cool environment when vernalization is complete. The Klehm’s Song Sparrow suggests cool nights between 35–40°F and days between 45 and 50°F. On sunny days, it might be necessary to turn on the fans in the greenhouse to maintain this colder temperature. Higher temperatures cause the plants to develop their buds more slowly and the flowers to deteriorate more quickly.
Fertilizer: Klehm’s Song Sparrow advises applying a low rate fertilizer, such as 18-6-8 at 100-150ppm at every other watering, in the spring when they are potted up. Flowering may be hampered by overfertilization.
How well do peony grow in planters?
One of my favorite childhood memories involves selecting peonies for my grandma from the large shrub that would bloom out front every year. Her favorite cut bowl florals were those with the enormous blossoms and vibrant color. Later, I had to develop in apartments, which is where I discovered how to be incredibly creative.
Peonies grown in containers and displayed in sizable pots with vibrant colors were on the menu. The zone you are in, the level at which the tubers are planted, and how to maintain moisture levels in a container must all be taken into account while caring for peonies in pots.
Many gardeners with limited room have become desperate enough to try huge plants in pots. Many bulbs and tubers grow well in containers as long as the soil is well-draining and some extra attention is given to it. Growing peonies in pots is a fantastic method for gardeners with limited room to enjoy the flowers or for anyone to have a large, robust, and colorful shrub on their patio.
If it’s currently in a container, you might need to move it to a larger pot. The container you choose should be at least 1 1/2 feet (46 cm) deep and as wide as possible. Peonies are big bushes that can reach heights of up to 4 feet (1 m) and have a comparable spread. They require a lot of space to spread their feet. To avoid tuber rot, make sure the container has enough of drainage holes.
Can peony be grown indoors in a pot?
Peonies are normally planted outdoors, but they can also be grown indoors in containers. It is better to sow peonies as tubers or young plants in the fall so they can establish themselves during the winter. If necessary, they can also be planted in the spring. When purchasing peonies, keep in mind that some have huge growths that require support. Additionally, tree peonies often have smaller root systems, making them potentially easier to grow in containers.
Select a container that has drainage holes, room to double or triple in size, and can fit the roots of the peony. It is best to use a substantial container (like clay) so that it won’t topple over as the peony grows bigger and bigger. Choose a light cover container for the peony if you intend to place it outside in the summer so that it won’t become too hot there.

With potting soil that has been combined with plant fertilizer, fill the pot approximately 2/3 of the way. Then make a hole big enough to accommodate the roots. Plant the eyes 2 inches beneath the earth where the plant emerges from the underground root stem.
When the drainage holes on the bottom of the planting pot are full, backfill the soil around the root and water the plant thoroughly. To prevent the container from sitting in water, always dump the drained water away. When the top 1 to 2 inches of soil dry out, keep watering the peony in the same way.
From late fall to late winter, keep the container in a location that is close to freezing (such as an attic or an unheated garage). To thrive, peonies require a cold dormancy. Water only when the soil dries out entirely during this period (test with finger).

Do peonies prefer shade or the sun?
- 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).

What happens if peonies aren’t pruned back?
In the winter, you don’t really need to do anything to or for your herbaceous bush peony plants. However, if you discover that you neglected to remove the stems in the fall, you still have time to do so.
Herbaceous (bush) peony, such as the intersectional Itoh peonies, eventually lose their leaves and stems when the plants hibernate for the winter. The stems will tumble to the ground and turn “mushy,” and the leaves will begin to decay. That is normal. The plant’s roots are not perishing; instead, new shoots and stems will appear in the spring. People may panic and believe their peony has perished, but this is simply the bush peony’s natural development cycle.
Be careful not to cut any exposed peony ‘eyes,’ which are typically pink or crimson buds and serve as the stems for the following year, while cutting off peony stems that are close to the ground. Put the stems and leaves in the trash after disposal. Peony stems and leaves shouldn’t be composted since they can harbor botrytis, a fungal disease, especially in moist environments. Each peony plant’s surrounding area should be cleaned up.
Most places don’t require mulching peonies. If you mulch your herbaceous bush peony plants, make sure to take it off in the early spring to avoid burying the roots too far. Years of mulching or applying bark dust around bush peony will eventually cause the roots to be buried too deeply, which could lead to fewer spring blooms. Just an inch or two of soil should remain above the roots of herbaceous bush peony after you remove that.
Additionally, it is normal for a mature peony’s crown to gradually heave up through the ground and display some exposed “eyes” in the winter. Don’t worry, peony plants enjoy the harsh winters.
Tree peony leaves must be removed from the ground and branches when they start to degrade. A tree peony’s branches are left hanging, barren and naked for the winter, rather of being chopped down in the fall. Don’t worry too much if you or a helper cuts a tree peony down to the ground and you panic or feel dejected. It’s likely that the roots have grown deeply enough to support spring branch growth. It might grow into a magnificent, revitalized tree peony in two or three years. I’ve seen it happen, so I know. In contrast to bush peony, tree peonies prefer more soil on top of the roots. Try adding a few inches of soil around the base of the trunk of a tree peony if it has lost its vigor. Yes, it is exactly the reverse of what is suggested for bush peony.
You can go outside again after the snow melts and it’s nice out to work on any “lost” stems.
