Because of its stunning spring and early summer flowers and appealing leaves all year long, peonies are well-liked perennials. For herbaceous peony (USDA Zones 38), which totally wither to the ground in the winter, follow these recommendations. Tree peonies, which resemble shrubs and have woody stems that are always visible (Zones 49), have slightly different needs.
Herbaceous peonies should be planted in the fall, when they are dormant. Peonies that are planted in the spring may not bloom for a number of years, and if they sprout new shoots before setting down strong roots, they may even perish. In the fall, mail-order and neighborhood nurseries sell bare-root divisions. A part of the rooted crown with multiple dark red growth buds known as eyes makes up a bare-root peony division. Every bud in the spring sprouts a stem. Look for a division with at least 3 to 5 eyes because the more eyes a division has, the fuller it will appear.
Fall is the best time to plant bare-root herbaceous peonies.
1. Select a location with well-drained soil that is far from competing tree and shrub roots. Give each plant a three-foot-diameter area to grow in. Because peony stems are prone to breaking when heavy with buds and blooms, avoid windy regions or provide a windbreak. In most places, a setting with direct sunlight is ideal. If your springs are often warm and dry, pick a location with afternoon shade.
2. Make the soil ready. Peonies bloom most profusely when allowed to grow undisturbed in the same spot for many years, therefore it’s crucial to put them in well-prepared, enriched soil. Make a planting hole that is 18 inches deep and 2 feet wide. Compost or well-rotted manure should be incorporated into the hole’s bottom with multiple shovels. Add dirt, additional compost, and a cup of bonemeal to the hole halfway. Also incorporate roughly a cup of ground limestone if your soil is acidic. pH levels of 6 to 7 are ideal for peonies.
3. Place the peonies. Setting the division too deep prevents blossoming; only 1.5 to 2 inches of soil should cover the eyes. Position the eyes so they will be just.5 to 1 inch below the soil surface if you garden in an area with a mild winter. This will expose the roots to as much winter cold as feasible. After setting the peony in the hole, firmly yet carefully pack soil over the roots. Verify that there are no air gaps that can permit the plant to root too deeply.
4. Use a hose to water the plant with a soft stream. After that, surround it with a light mulch, like chopped leaves or evergreen branches, to help control soil temperature and moisture and lessen weed competition. In order for the plant to fully cool, mulch should be removed in the winter. The first year the peony may not bloom, but by the third year it should be in peak condition.
Should you soak peonies with bare roots before planting them?
The peony’s lengthy life is one of its greatest draws, in my opinion. Herbaceous peonies have been known to bloom consistently for more than 50 years, occasionally outliving the gardeners who first planted them! But the care you take in setting them up is the secret to their durability.
In my experience, the first few leaves turning color in the fall are the best time to sow bare root peony tubers. After a plant is described as being “bare root,” it signifies that when it was dug up from the ground, all of the soil surrounding the tuber was removed. Since bare root peonies are less expensive than container-grown plants and may be planted in the autumn, they have more time to establish a strong root system and will be better prepared for robust growth the following spring.
The first thing you should do when you open the package of bare root peony, whether you bought them from a neighborhood garden center or via mail order, is to make sure the plant is healthy. The tubers have to be solid, meaty, and mold-free.
In order to rehydrate bare root plants before planting, it is a good idea to soak them in a pail of water for two to four hours.
If the tubers can’t be planted straight away, keep them in their packaging in a cold, dry location, such a garage or basement. Check on the tubers occasionally to make sure they aren’t turning soft or moldy because warmth and moisture will encourage them to begin developing. They can be stored in this manner for about five days.
Planting Location for Peonies
Select a location with well-drained, slightly acidic soil that receives direct sunlight. Additionally, keep in mind that once established, peonies do not respond well to transplanting, so choose a location where they can be left alone.
Planting Peonies
Peonies should be planted with their eyes facing upward and close to the soil’s surface. Now, this is a crucial point to remember. Too-deeply planted peonies won’t produce flowers. Plant the tubers no deeper than 2 inches in northern gardens. They are buried approximately a half-inch deep in my garden in the middle of the South. This enables the mulch I apply over the planting bed to discourage weed growth and aid in moisture preservation.
After planting, give the area plenty of water and keep it continually moist until the ground freezes.
What to Expect After Planting Peonies
Your peony will develop foliage in the spring of next year, but it can take a few seasons before it blooms profusely. But you’ll be rewarded for your patience. Peonies are plants that are designed for lengthy lives, and as they become older, their blossoms get better.
Many of the traditional cultivars, including “Sarah Bernhardt” and “Festiva Maxima,” have big, heavy blossoms that have a propensity to topple over. Caging them in the early spring, right after the stems appear above ground, is one of the best strategies to prevent this. To support them, use a straightforward metal ring with legs, or simply enclose the plant in a section of wire fencing.
Caring for Peonies After they Bloom
Peonies also have a wonderful smell, but in order to ensure that there will be a lot of bloom the following year, it’s crucial to remove the seedpods and fertilize each plant in late spring or early summer after deadheading the faded petals. You might sprinkle a 5-10-5 mixture around the base. Per plant, about a handful is sufficient. You only need to feed plants at this time because fertilizer overuse can produce burn, fewer blooms, and lanky growth.
What is a Bare Root Peony?
A bare root peony division is one that removes the soil from a peony plant that has been dug up and divided in the fall (for propagation reasons).
Will My Peonies Bloom the First Year?
Peonies need 3 to 4 years to establish themselves as a fully mature blooming plant, as opposed to annuals. The first year of growth is dedicated to producing roots and establishing the plant in the garden. If blooms occur the first year, they may be smaller and not of the typical form or color of a mature planting. In fact, the first or second year some peony may not even blossom. By the third year, there will be a profusion of blossoms, which will be a fantastic reward for patience. “The First Year They Sleep, The Second Year They Creep, and the Third Year They Leap,” goes the proverb concerning peony.
Why are My Peonies Not Blooming?
More than “They were planted too deep,” there are numerous other reasons why peonies do not blossom. Before a rational explanation for why a plant has failed to blossom can be drawn, many questions must be asked.
Young plants could not have a strong enough root system or enough food reserves to blossom.
Compared to most domestically grown plants, imported roots are substantially smaller. For smaller roots to develop a suitable root system with enough food stores to create a bloom, they may need to grow for a few more years. A good peony root should contain at least three comparable roots measuring four to six inches in length and an inch in thickness, as well as three to five “eyes” (dormant buds) for growth.
Frequently, a peony that was planted at the same time as the rest of the groomed yard is now shaded by much larger trees. To bloom successfully, peonies require a minimum of eight hours of sunlight.
In the spring, when there has been a lot of rain and there is a lot of humidity, a fungus can damage tender new growth with forming flower buds. The disease’s symptoms show on pea-sized immature flower buds; these flower buds fail to develop and appear dark or blackened on the terminals of fresh growth. Plantings in their first and second years are more prone to this illness. The best way to control illness is still to cut back and remove peony foliage in the fall.
At the base of each stem, peonies generate latent buds in August that are referred to as “eyes.” These dormant “eyes” should be placed 1 1/2″ to 2″ below the soil’s surface in order to create a peony bush the following spring. In the fall, carefully scrape the soil around a few stems to measure the depth of the young ‘eyes’ at the base of each stem if you are unsure of the planting depth of an established bush. In our fields, we plant thousands of roots each fall without first measuring planting depth as we drop them into a furrow, so it is rare for a peony bush to be planted too deeply and be the cause of a lack of blooms. By developing dormant eyes at the correct depth as they mature, roots often self-correct the depth at which they were planted. Too frequently, hasty counsel is provided, and peonies are pulled out and replanted without understanding that disturbed peonies frequently suffer setbacks and repeatedly delayed blooms. Once planted, peonies perform best when left alone.
Do Peonies Ever Have to be Divided?
One of the longest-living perennials is the peony. It is not uncommon for peonies to live fifty to one hundred years without ever having to be divided, provided they are grown in rich organic soil with good drainage and a site with eight or more hours of sunlight.
Are All Peonies Fragrant?
Sadly, not all peonies have a strong fragrance. Red blooming cultivars typically have less fragrance than pink and white blossoming ones. All hybrid kinds besides the yellow Itoh (Intersectional) Hybrids lack scent.
Are Ants Needed to Open Blossoms?
There is no truth to the tale that has been passed down through the years. Ants are drawn to the sugar on flower buds in the same way that they are to picnic treats. Our fields have very few ants but an abundance of blossoms every year.
When is the Best Time to Cut Peonies for Arrangements?
early in the morning, before buds enlarge and open. When the flower bud is in the “marshmallow” stage, when it feels soft to the touch, cut the stems. Cut double flowering plants when they are about a quarter open. The bloom’s vase life will be shorter the more fully opened it is.
Why do my Peony Plants Fall Over After a Rain?
After a significant downpour, double flowering types are typically affected by this issue. Large flowers merely trap the rain, become overburdened by it, and collapse. Japanese and single types, along with more compact kinds with thicker stems, stay up better during rain. Peonies cultivated in semi-shade also have weaker, thinner stems than those grown in full sun.
Do Peonies Need to be Mulched for Winter Protection?
To avoid frost from heaving roots out of the soil, we advise mulching first-year plantings as the earth begins to freeze. Once established, the majority of peony are quite resilient and never require mulching, while hybrids can be harmed by a winter with no snow cover. A good winter mulch is advised for hybrids in harsh environments, such as regions where the temperature is frequently below zero degrees Fahrenheit.
