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.
How should soil be prepared for peonies?
Dig the dirt 12 to 18 inches deep in order to create the planting hole for a bareroot peony “. To make the sidewalls of the planting hole more pliable, use a garden fork. To the bottom of the hole, add a shovelful of compost and a handful of an all-purpose, organic, granular fertiliser. Next, fill the hole with the original dirt. The peony root should be placed on top of the cone with its roots dangling down the sides after creating a “cone” of this altered soil inside the planting hole. It’s crucial that the “eyes,” or growth nodes, at the old stem’s base don’t extend farther than 2 “beneath the soil’s topsoil. The plant may thrive if the peony root is positioned deeper than this, but it will likely bear few, if any, blooms. Plants grown in containers can be planted in a similar way. Just create a hole that is no deeper than the root ball and twice as large. As above, amend the soil. Make sure the soil surface in the pot is level when planting so that the new plant grows in the ground.
Beautiful flowers on the left have collapsed from their own weight. An Essex Plant Support, seen at right, was erected in the early spring to allow the foliage and flower stems to climb through the support rings and grid.
Supporting Your Peonies
You may wish to give your peonies some support during the flowering season, depending on the type and the growth environment. This is particularly true for double or “bomb”-style flowers, which are prone to becoming weighed down and saturated. Before the plants grow taller than a few inches, the supports should be placed early in the growth season. Once the plant has filled out, and especially when it’s in bloom, it is nearly impossible to set up an effective support system.
How may acid be added to peony soil?
A pH of 6 to 7 is ideal for peonies’ prefered soil, which is neutral to slightly acidic. Using a soil test kit from a garden centre or getting a soil analysis from a testing lab in the autumn gives you time to alter the pH before planting peonies the following spring and is the best way to find out whether your soil is the right pH for planting peonies.
According to Clemson Cooperative Extension, adding ground limestone and thoroughly incorporating it into the top 7 inches of damp soil helps increase the pH of very acidic soil with a pH below 6. If the pH of your soil is higher than 7, indicating that it is excessively alkaline, you can add sulphur or aluminium sulphate to make it more acidic. The kind of soil and the pH at the beginning determine how much lime or sulphur should be added. Based on the kind of soil and the pH at the time of testing, a soil test result typically suggests how much of either amendment should be applied.
What kind of compost works best 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 fertiliser, 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 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 fertiliser, 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 fertiliser 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 colour.
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 utilised 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.
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 splendour. 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 colours 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 neighbours 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.
