It’s crucial to start with robust nursery stock and place a fresh planting in a location where it will grow because peony of all varieties can be perennials that live for exceptionally extended periods of time while also requiring little maintenance.
Every kind of peony requires:
- pH of 6.5-7 indicates fertile, well-drained soil that is mildly acidic to neutral. Never put in a peony in a wet spot or one where there is long-term standing water.
- Peonies of every variety will flourish in direct sunlight. Herbaceous and intersectional peonies require at least 6 hours of direct sunlight per day to flourish well. Tree peony grow vigorously and do well in full sun, but growing them there has the drawback of having flowers that fade very rapidly.
- In regions with diffused sunlight or an eastern exposure that receives morning sun and afternoon shade, tree peony will also thrive and produce flowers. The flowers will stay longer, but growth will be a little slower than in the full sun.
You can still grow lovely peonies if you garden in an area with heavy clay soils, depleted soils, and/or very acidic (low pH) soils as long as you take the right procedures to amend the soil in the new peony planting area. In order to give the peony with long-term nourishment, this basically means changing the pH of the soil to the proper level, creating looser, more permeable soil in places of thick clay, and adding enough organic material to deficient soils. Spending a little time and effort now can result in years of gorgeous flowers. We hope the video and illustrated step-by-step instructions below will help you establish the best area for planting peony. Send us an email at if you have any queries.
How to create a fresh peony bed for planting in the fall in an unimproved or lawful area, step by step:
If you’re planting peonies in a new garden space, pick a spot that gets six hours of sun per day (tree peonies will also grow well in dappled shade, but if you are planting herbaceous or intersectional ponies, select a full sun location.) Peonies also need a well-drained environment as a basic requirement.
Make sure the soil in the garden bed is deep enough to support the vast root system of a peony. If the soil is rocky, don’t worry about it; just avoid planting where there are only a few inches of soil above a boulder or rocky ledge.
Our soils in New England are frequently sandy and rocky, as well as having low levels of calcium and phosphate. The native soil in our region has a pH between 5.0 and 5.5, which is far too low for good peony production. Fertility can be increased by amending deficient soils. It’s always a good idea to have your soil tested so you can determine the baseline fertility and mineral levels in your soil.
Peonies should be grown in raised beds or mounds in thick clay soils with poor drainage. Making raised beds can enhance many garden areas.
To our planting space, which is 3 × 3 feet, we apply 2 pounds of each of the following soil-building supplements.
Do peony appreciate soil with acidity?
Peonies make wonderful cut flowers and are used as examples in herbaceous hedges and borders.
For healthy bloom, herbaceous peonies require at least six hours of direct sunlight each day. In warmer climates, shade in the afternoon will prevent flowers from withering too rapidly. Since the big, silky petals of tree peony are harmed by too much sun, they should always have dappled or afternoon shadow.
Loamy, well-drained soil is ideal for peony growth. To prevent fungal infections and root rot, good drainage is essential. Compost, finely crushed pine bark, or well-rotted manure can be added to heavy clay soil to increase drainage and organic matter levels.
A pH of 6.5 to 7.0 is ideal for peonies. To make your soil more acidic for peonies to grow well, you might need to apply lime. Peonies survive a long time in the garden and are worth the extra effort when planting them because they may remain in the same location for many years.
For planting, fall is ideal. Make a 12 to 18-inch-deep and 12-inch-wide hole. Spread the roots across a portion of the soil that has been replaced in the shape of a cone. The roots should be placed such that the eyes, which are bulging pink or crimson buds, are no more than an inch below the soil’s surface. Deep planting is the primary factor in bloom failure.
The best time to grow tree peony is in the fall. One inch below ground level is where the graft union should be. For the first winter, build up additional earth mounds around them.
Air pockets are removed by thoroughly compacting the dirt around the roots. Thoroughly water.
Divisions with three to five eyes will mature earlier than divisions with fewer eyes. Before the plant blooms, it may take one or two eye divisions, which could take several years.
Once every 10 to 14 days, deeply and thoroughly water peony. Deep irrigation will promote deep roots. Peonies are exceptionally drought-resistant once they are established.
In the spring, when the stems are approximately 2 or 3 inches high, use a low nitrogen complete fertilizer, such as 5-10-5 or 5-10-10, at a rate of two to three pounds per 100 square feet. If well-rotted manure is spread to the soil’s surface in a 1- to 2-inch layer, it can be used to improve the soil. Never let manure or fertilizer get in contact with a plant’s stems.
In the early spring, be mindful of the sensitive developing shoots when working around the plants. They are typically a dark crimson color.
After flowering is complete, remove seed heads to give the plant more energy to store for the bloom the following year.
Cut down the dead stems of herbaceous peony in the fall, after the ground has frozen, to the soil’s surface. If you have ever experienced sickness issues, this is really significant. Throw away the stems. The compost pile shouldn’t be utilized for them.
NEVER prune tree phlox. Since they are shrubs, cutting them will result in their death.
Peonies can grow for many years without being disturbed. You should divide or relocate your peony in late September or early October. To reveal the eyes, carefully lift the clump and remove the dirt. Divide the clump into parts, each with three to five eyes and sound roots, using a clean, pointed instrument. Replant right away.
The stems of the majority of peony require support to keep them from collapsing under the weight of their blossoms. For this use, commercial hoops are readily accessible. In order to secure the plants to the stakes for support, you can also use a ring of three or four stakes with loops of tape or plant ties.
Pick peonies when they are still in the soft bud stage if you plan to cut them for your home. They ought to have a marshmallow-like texture. On each stem of the plant, leave at least three leaves. Remove any leaves that would come in contact with the water in the vase and recut the stems in warm water. Within a day of being put in a vase, the flowers ought to begin to bloom.
Can peony grow in containers?
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.
Any soil may peony grow in.
Although peonies are quite adaptable, their optimal soil is well-drained and somewhat acidic (6.5-7.0 pH). Compost or a soil mixture designated for azaleas and rhododendrons can be added to heavy, clay soil to help your peony plant settle in more quickly.
Which compost kind is ideal for peonies?
You only need to place our peony level with the top of your soil because they come potted and are already planted at the proper height. You must create a hole that is approximately 30 cm wide and deep. Dig a small amount of bone meal or a general fertilizer, such as Grow More, as well as some high-quality garden compost, such as compost for roses, trees, and shrubs. Manure should not be mixed with soil since it could ruin the eyes. If some compost leaks out when you plant, don’t be concerned. More flowers will result from planting peonies in a sunny location, but they can also grow well in a semi-shaded location, producing fewer but longer-lasting blossoms. Your peony won’t bloom if you plant it too deeply.
Avoid overwatering your peonies because this is one of the main reasons they fail. The basic rule is to water sparingly, and it’s best to forgo watering altogether if you are unsure.
For taller kinds in more open locations, provide staking to maintain your peony’s best appearance.
With the use of John Innes No. 3 compost, peonies can be grown effectively in pots. Peonies do not perform well in composts that contain peat. Try to stay on the dryer side and be careful not to overwater. Plant them in the garden where they can grow to their full potential after a few years.
Peonies are exceptionally resistant to pests and diseases. Particularly mature plants rarely have issues. Stems can decay and collapse as a result of peony wilt, which typically occurs either before or after flowering. If this is observed, remove the afflicted stem. Beginning in July, Cladosporium can cause dark blotching on leaves. Both diseases are typically not lethal to the plants. These diseases can be avoided by maintaining a healthy air flow around the plants, particularly at ground level. In order to stop this from happening again, remove all foliage in the fall and discard it. Deer and rabbits avoid them.
Ants could be seen on your peony. Don’t Stress! Peony blossoms release a sweet, sticky material that draws ants like a magnet. Your peony is not harmed in any way by the ants.
Do peonies respond well to bone meal?
Early spring and again after blooming are the best times to feed peonies. A strong nitrogen fertilizer like Miracle-Gro should be avoided because it will produce tremendous foliage but little flower (and weak, floppy stems). Espoma Bulb-Tone is used because it contains potash and bone meal, the ideal nourishment for peony.
Do peonies benefit from blood and bone?
Peony fertilization is quite similar to springtime rose fertilization. For fertilizing peony plants, use a good organic rose fertilizer, bulb fertilizer, or perennial flower fertilizer. Traditional peony fertilizer also includes generic bone meal (and is a key ingredient in many rose and flower foods). Look for a phosphate rock dust product if you’re looking for a mineral-based peony fertilizer. A lot of mushroom composts work well as plant-based peony fertilizers.
Make sure the fertilizer you selected for your peonies is organic, contains less nitrogen (N), and is higher in phosphorus (P). I enjoy searching for goods that have been certified safe for use in organic agriculture by OMRI. In accordance with the manufacturer’s recommendations and local laws, apply the fertilizer sparingly.
Need ericaceous soil for peonies?
Although peonies have a brief blossoming season, their blossoms are magnificent.

Some flowers may discourage you from planting them because of their fleeting splendor. It is simple to believe that other plants and flowers will be more valuable if they have a flowering season that is quite brief.
One such flower that is frequently disregarded due to this flaw is the peony.
They are gorgeous when cut for the house, come in a variety of colors from pure white to lemon yellow, through pink to deep crimson, and are amazingly beautiful.
I wouldn’t be without them, and I’ve gotten around their short flowering season by planting them not only alongside other perennials with longer bloom times, but also in a few short rows on the vegetable garden, where they can be plucked for cut flowers without affecting the look of the bed or border as a whole.
Peonies thrive in any excellent, well-drained soil and are content in chalky soil as long as a little decent planting material is added to the soil to liven it up. Give them good lighting for the best outcomes. While they will function well in dappled shade, they will struggle in extreme darkness.
But deep planting is the most typical reason for failure with peony. They resemble yamas in that their roots are plump and tuberous, and if they are planted too deeply, they tend to produce more leaves than blooms. The simple fix is to dig them up and elevate the roots’ level so that the tuber lies just little below the soil’s surface. Once planted, you won’t ever need to relocate them again because peonies are content to grow undisturbed year after year.
Once established, they don’t require much in the way of care and attention, but they do benefit from some support because those double blossoms are so hefty. When they are about a foot tall, place one of those circular, plastic-coated wire supports over each of them before they are tall enough to push through it. Their foliage will conceal the building, providing stability in wind and rain.
In the months of May and June, peonies put up an amazing show. Once they stop blooming, their foliage will work as a contrast to the flowers of their neighbors if you are clever with the planting on either side of them. Although the flowering season is brief, no boundary perennial provides a more impressive display.
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.
