I’d want to add some peonies to my landscape. What time of year is optimal for planting? Tulsa, Kelly
A: Many trees and perennials are said to grow best in the fall, and peonies in particular seem to thrive when planted in September and October.
With their gorgeous blossoms and rich foliage, they are difficult to miss in the landscape. They are also one of the most durable and straightforward perennials to grow. Peonies can outlive many gardeners if they are planted properly and in the right location.
Decide first where you will plant. Peonies prefer rich, well-drained soil and full light for at least six hours each day. The moment has come to loosen and replenish your soil with compost if it is heavy. Peonies prefer a neutral pH for the best blooming. A soil test will reveal whether extra amendments are required if you are unsure whether your soil meets the requirements.
You should have your hole prepared before planting, and especially before transplanting, to prevent the roots from beginning to dry out. Adding some well-rotted compost or a slow-release balanced fertiliser is a good alternative at this point. Don’t go overboard Nitrogen excess can stop flowers from blossoming. The eyes or buds of root clusters should be planted in holes that are just 1-2 inches deep. Too deep of a planting will produce few or no blooms. Make the soil around water and roots firmer. For several weeks as they establish themselves, roots should be maintained wet. On new crops, a very thin layer of mulch will assist control soil temperature.
How well do peony grow in Oklahoma?
Currently, we don’t provide mail-order peony. The nursery exclusively offers them for sale in pots.
Many people think of peonies as the queen of all perennial flowers. They will thrive for many years without being divided and are without a doubt one of the easiest perennials to cultivate in a wide range of soils. Even in central Oklahoma, where the summers are extremely hot, planting peonies in the full sun will yield the finest results. Give them at least a half day of sun if full sun is not possible.
Peonies should be planted in holes that are deeper and wider than the root or container. Just below the root or container, incorporate several inches of rotting manure or compost into the soil. In the centre of Oklahoma, plant the root with the pink or white eyes up and no deeper than one inch into the ground. All of our peonies are offered for sale potted in two-gallon containers with at least three to five eye divisions. When they first emerge in early March, we pot them in the fall and start selling them for sdale in the spring. A peony you purchase from us has been properly planted for you. All you need to do is take the plant out of the container and plant it in your garden so that the top of the soil line is level with the soil’s surface. Peonies purchased elsewhere and sent in from further north may be planted deeper and may not thrive in our region of the country when planted that deeply. Peonies won’t grow well if you buy them bare root in the spring and put them in central Oklahoma, where it becomes too hot too early in the season. They might even die. Moreover, avoid mulching peonies. The buds will have a harder time getting cold enough as a result of this. Peonies are tolerant to cold and will grow all the way to Alaska.
Peonies do not need a lot of water to grow after they are established. In the middle of summer, the leaf may turn brown here in central Oklahoma, but the plant is unaffected. Peonies require watering the first year, just like all other plants, but after that they pretty much take care of themselves.
In central Oklahoma, peonies do not blossom for three basic reasons.
First, the eyes are set too far back. The peony region’s southern boundary is where we are located. For the eyes to set blossoms for the following year, many hours of chilly weather are necessary. The eyes won’t get cold for long enough and won’t set blossoms if they are placed too deeply. The plant isn’t receiving enough sunlight, secondly. For most sun-loving perennials to bloom successfully, they require at least one half day of sun. One of these perennials is the peony. Thus, place them where there is the most sunlight. Third, types that bloom early or in the middle of the season need to be planted in central Oklahoma. Our springs frequently shut off at a high temperature rather early in the spring. That will result in the wilting or drying up of peony buds and flowers. Only early and midseason blooming cultivars are being grown here. All of the peony cultivars we sell have undergone extensive testing in our growing and display areas, and we have had great success with them. If planted appropriately, the peony you purchase from our nursery will thrive and blossom successfully for you.
Peonies come in a huge variety, which we grow. These images show the majority of the kinds we plant. Herbaceous peonies come in three primary varieties (also known as garden peonies). They come in single, Japanese, double, and bomb varieties. The single and Japanes are lighter in weight and typically hold their position effectively in our Oklahoma winds without staking. In Oklahoma, staking is frequently required to keep the larger bomb and double varieties’ flowers upright on the plant. We also raise a small number of intersectional peonies, which are a hybrid of tree and herbaceous peonies. They grow like herbaceous peonies, but the blossoms are more colourful and resemble tree peonies. Look for the name and type of peony under each image. If the variety is reputed to be aromatic, we will also let you know.
How late can peonies be planted?
The optimum time to plant peonies is in the fall, any time between late September and early December. When purchasing a potted plant in the spring or summer, it is better to wait until fall to transplant the plant. To ensure good drainage, you can temporarily bury the entire pot where it will be planted, covering the soil beneath it with a few inches of gravel.
Follow these planting instructions in the fall:
Make a deep hole that is at least 24″ wide and 18″ deep. Rich, humus-rich soil as well as a lot of compost, composted manure, or peat moss should be used to fill the hole’s bottom.
Remove the plant from its pot with care, being sure to untangle any circling or tangled roots.
Place it there and backfill the hole with the same soil mixture as you go. When planting is finished, make sure the top of the plant’s bud “eyes” is no lower than 2 inches below the top soil level, taking into consideration any additional mulch layer you’ll add.
When should peony be planted?
Although perennials, peonies take time to establish themselves and begin flowering while having a very long lifespan. The majority of peonies flower the second spring following planting, though they may bloom one to three years later. However, your perseverance will be rewarded for a very long time with fluffy, fragrant flowers and lovely leaves. Peonies are relatively low-maintenance and trouble-free perennials once they are established. Planting peonies correctly and in a location where they will thrive are essential to their success.
When to Plant Peonies
Fall is the best season to plant peony, with at least six weeks to go before the ground freezes. Peonies can also be planted in the spring, but it might take them a little while longer to start blooming.
Where to Plant Peonies
The majority of peonies grow in full sun, which is defined as 6 to 8 hours of daily direct sunlight. Peonies, however, favour direct morning light over direct afternoon light in southern latitudes. Peonies struggle in poorly drained soils, just like many other perennials. They favour nutrient-rich, well-drained soil that is high in organic matter and has a pH that is neutral or just barely alkaline. You can improve your soil with compost or well-rotted manure if it isn’t in the best condition. The plants can grow rather top heavy with flowers throughout the blossoming season, therefore it’s important to protect them from high winds even though peonies prefer adequate air circulation. Avoid placing peony too close to plants that compete with them for light and nutrients, such as trees and bushes.
Peonies fit easily into perennial gardens and landscapes due to their adaptability. In the flower garden, along a sidewalk, or as a tiny floral hedge, you can plant a specimen. Choose a selection of early, mid-season, and late season kinds if you want to lengthen the peony season and enjoy blooms for up to six weeks. Remember to leave 24-36 inches between most peonies when organising your plantings.
How to Plant Peonies
Dig a hole for Itoh and herbaceous peonies that will enable you to extend the roots out without bending them. Plant the fleshy peony roots with the eyes no deeper than one or two inches. Peonies might not bloom if they are planted too deeply or too shallowly. Around the roots, tamp down the earth. Water wisely. Over the winter, cover with a 2 layer thin layer of loose mulch, and then remove the mulch in the spring. We also advise using a hoop-style stake to stake your peony at planting time because the blossoms can become extremely heavy and cause the stems to break.
Where would be the ideal location to grow a peony?
Peonies prefer an area with good soil drainage and sunlight. A healthy airflow around the plant is also crucial. Peonies are able to avoid their sole significant disease issue, botrytis, thanks to these growing circumstances.
Botrytis can be found in most soils, just like other fungi-related illnesses. Only poor plants, unusually cool and wet conditions, sick plants nearby, or weak plants rarely become an issue. Blackened buds, stems, and occasionally decaying at the base of the plant are indications of botrytis. Disconnect and remove any impacted areas (put this material in the trash, not in your compost pile). Preventing botrytis issues is the best course of action, and this starts with careful planting.
The gorgeous semi-double Abalone Pearl peony has gentle pink-peach petals that contrast with bright orange anthers.
When can peony be transplanted in Oklahoma?
Peonies can be left in the garden unattended for a long time. But on occasion, it’s important to relocate established plants. To improve flowering, move peonies that are sheltered by tall trees or shrubs to a sunny location. The peony may need to be relocated in order to redesign a perennial bed or border. Plants that are large and robust can be dug up and divided for further growth.
The ideal month for transplanting established peonies is September. Cut the peony stems at or just above ground level to start. Next, thoroughly excavate each plant’s perimeter and its base. Keep as much of the root system as you can. Replant the peony right away in a sunny, well-drained area.
Large peony clumps must be divided in a number different ways. Shake the clump carefully to remove any loose soil from the root system after you’ve dug up the plant. Section off the cluster using a big knife. Each division needs to establish a strong root system and at least three to five buds (eyes). Smaller divisions will take longer to mature into beautiful plants.
The optimal conditions for peonies are full light and well-drained soil. Choose an area that receives at least six to eight hours of direct sun each day when choosing a planting site. Avoid standing in the shade next to big trees and plants. Compost, peat moss, or leaf mould used in significant quantities can typically improve poorly drained soils.
When planting a peony, make sure the hole is big enough to fit the plant’s root system comfortably. With the buds one to two inches below the soil’s surface, place the peony plant in the hole. (Peonies frequently don’t bloom successfully if the buds are deeper than two inches.) As you backfill the hole, compact the soil around the plant as you fill it with soil. then thoroughly rinse. Peonies should be spaced three to four feet apart.
Apply a four to six inch layer of mulch over the newly planted peonies in the late fall (mid-November to early December). Pine needles and weed-free straw are great mulching materials. Mulching keeps the soil from repeatedly freezing and thawing in the winter, which could lift the plants out of the ground. Early in the spring, before growth starts, remove the mulch.
Peonies that were transplanted might not bloom well the first spring. However, by the third or fourth year, the number of flowers should increase quickly.
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.
Fall is the ideal season to plant peonies. This is often when peonies purchased from a catalogue will be delivered. It’s okay to plant peonies when you see them flowering and for sale in containers in the spring.
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.
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 colour 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.
