Growing more plants from a single peony is known as propagation. When you want to share a beloved peony plant with a friend, grow more divisions of a favorite cut flower, or save a traditional heritage variety from Grandma’s backyard, it can be helpful to know how to propagate peonies.
Peonies can be propagated via a variety of techniques, each of which offers advantages. Some are pretty easy, while others are challenging or intricate. As contrast to many other plants, peony grow slowly, therefore all of these tasks call for patience. Peonies are a great choice for the garden because they typically require little maintenance and have a long lifespan.
Crown/root division of plants that are three years old or older is the most typical technique of propagation for herbaceous peonies. The optimum regions to cut away to generate a division will depend on the cultivar because each one will have a different crown structure. Making a division should result in a plant with three to five eyes on a crown and a strong enough root system to sustain it for a year or two.
Please take note that when peonies are dug up, they should be separated into divisions. Without division, digging, transplanting, and replanting entire clumps will result in the plants slowly deteriorating. New roots will grow as a result of the division, producing a healthy plant that will be a wonderful garden accent for many years to come. For more comprehensive directions on how to divide peony, see the list of additional resources below.
Does the peony spread?
No, peony won’t naturally grow more plants or spread out. One day you may realize that your peonies have grown rather large and have spread out quite a distance.
If you want to grow more peony plants in this situation, dividing them is your best option. This is the finest approach to propagate herbaceous peonies and a way that you may aid in it.
Peonies can’t actually be encouraged to grow or anything like that. Simply put, it’s better to hold off on taking any action until the peony plant has grown larger.
Dividing peony plants is the only way to produce more of them. Although this method isn’t inherently difficult, you’ll want to become familiar with it so that you can carry it out correctly.
To get more peony plants, read on to find out how to divide existing ones. This will enable you to plant peonies in several garden locations if you so want.
Do peony reproduce via seed?
Before resetting, most roots benefit from a trim. To prevent congestion and encourage new growth, trim roots to lengths of approximately eight inches.
The peony family is diverse. hybrids have some “roots that may be separated from their rhizome and planted to produce new eyes are known as adventitious roots. After two or three years of growth, these root cuttings can be spread out in rows at a depth of two inches and lifted in the fall.
Knives, scissors, and spades used to cut rhizomes, roots, and foliage should all be sterilized. Fungi and viruses can be killed by a 10 percent or 70 percent solution of rubbing alcohol and water.
Utilize a dipping solution of a “Bordeaux mix, an alternative to fungicide dust, is a mixture of copper sulfate and hydrated lime. Both call for the wearing of thick gardening or rubber gloves.
On fresh plants, don’t compact the soil too firmly. You run the risk of breaking or pushing eyeballs deeper than two inches. When in doubt, overfill the hole and place your eyes as close to the surface as possible.
If you cut the stem sufficiently deep, you can use cuttings to spread soft-stemmed perennials like peonies. Peony stems emerge from “eyes that appear from rhizomes just below the soil’s surface. The most dependable methods of propagating these perennials are by rhizome cuttings and seedling growth. Unlike plants developed from seeds, rhizome cuttings typically blossom one to two seasons after planting and always give rise to a plant that is identical to its parent. For flowers in the spring, take cuttings in the fall.
Fill planting holes with a bushel or two of adjusted soil by mixing equal parts garden soil, peat moss, compost, and manure. For every bushel of filler, mix a small amount of bone meal, superphosphate, or another low-nitrogen fertilizer. For each, create a hole that is one foot wide and two feet deep “To determine how many you will have, divide or plant additional plants. Unused holes can always be filled with dirt. On either side, provide each plant about three feet of room.
- If you cut the stem sufficiently deep, you can use cuttings to spread soft-stemmed perennials like peonies.
If peony roots dry out, the plant will be set back and may not bloom the following season, so pick a day when the soil is damp rather than dry to start. In the fall, after removing the summer mulch and trimming back the dead foliage, dig peonies. Lift the entire root ball by making a deep cut underneath the roots with a spade or garden fork all the way around. Once the ball has been raised, use a hand cultivator or trowel to remove as much dirt as you can. If you are excavating more than one peony, focus on one plant at a time.
Remove any remaining dirt from the roots, fleshy root, and rhizome with care. On the top part of the rhizomes, look for the tiny eyeballs. Avoid breaking any buds at any costs. These stem bases serve as the foundation for fresh peony growth, and once broken, they cannot regrow.

- Lift the entire root ball by making a deep cut underneath the roots with a spade or garden fork all the way around.
Use a sharp knife to cut each rhizome into numerous pieces. Each component needs a set of roots and three to five eyes. Apply an anti-fungal powder, which is readily available at most garden centers, to each portion of the rhizome. If the peony you are dividing is particularly huge or old, use a spray bottle to keep the roots moist as you cut the rhizome.
Trim older or damaged roots on divisions and discard any pieces that are rotted or discolored. Eliminate soggy roots; they can contain nematodes or root rot. Spread roots while suspending the rhizome over the hole and amending the soil in the holes. When the hole is filled, position the rhizome so that the eyes are only a few inches below the surface. More than two inches of eye burying will probably prevent blooming. In southern growth zones, plants should be placed no deeper than 1.5 inches. Water the new plant thoroughly once the hole has been filled.

Do peony bushes grow in number?
If you’ve been thinking about growing peony plants, you should be aware that there are crucial procedures to take. Peony plants must be divided in order to be multiplied. Although it can seem difficult, this is not.
First, dig all around the peony plant with a sharp shovel. Take extreme care not to harm the roots. Make sure to remove as much of the root as you can.
Once the roots have been removed from the earth, thoroughly rinse them with the hose so that you can actually see what you have. The crown buds are what you are seeking. When you divide peonies, these are the parts that eventually break through the soil and create a new peony plant.
You should place the roots in the shade after rinsing to allow them to somewhat soften. It will be simpler to cut them. The roots of peony plants should be cut all the way back to just 6 inches (15 cm) from the crown when you are reproducing them. Again, this is because, when you divide peony plants, you must plant a crown with each piece since the crown grows into the peony.
Make certain that every component has at least one crown bud. The ideal number of crown buds is three. However, one is sufficient. When you have as many peonies as you can from the roots you initially dug up, you will stop dividing peonies.
Place the fragments in a spot where peonies can grow. Make sure the pieces’ buds are not buried deeper than 2 inches (5 cm), as this could hinder their ability to grow. You can actually keep your pieces in peat moss until you’re ready to plant them on a warmer day if the temperatures are reasonably consistent. A prolonged period of storage could cause them to dry up and stop growing.
Now that you are aware of how simple it is to propagate peony plants, you can quickly start dividing existing peonies to produce a large number of new ones.
If deadheaded, will peonies blossom again?
Peonies do not blossom again if you deadhead them after they have bloomed. No matter what, these perennials only bloom once a year. Deadheading peonies does, however, enable the plant to concentrate on preserving energy for the growth of the following season as opposed to producing seeds.
Are peony flowers capable of producing seeds?
We save the seeds from our Northwest Cultivar Group (rockii) tree peony every year. You can place an online order for them or mail us $12.50 to get 25 freshly picked in late August. (Postage is included in price.) A small number of different peony seeds are also available for purchase. Please visit our website for further details. Send in your requests as soon as possible because we can only offer a certain quantity of seeds per year.
Many of the seeds from the hybrid tree peonies in the Northwest Cultivar group p.rockii will grow into plants that produce these stunning white blooms with crimson flares (blooming in about four years). This flower’s shape and color closely resemble those of the P. rockii wild species.
The period to gather the peony seeds for this year will be in August. Try your hand at growing a harvest of peonies from seed if you left the pods on the plant throughout the summer because the vast majority of peonies produce viable seeds. Peonies grown from seed do not look exactly like their parent plant, despite possible striking similarities. Nearly all cultivated tree and herbaceous peony are hybrids that are very different from their predecessors in the wild. Seeds gathered from a single peony species that did not cross pollinate with other peonies are the exception to this rule.
Peonies that are intersectional hybrids (Itoh) are sterile and do not produce viable seeds. Sadly, other popular garden plants, including the high-tech herbaceous hybrids “Coral Charm” and “Lois’ Choice,” are also infertile. Most ‘lutea’ hybrid tree peony from Europe and America, such ‘Leda’ or ‘High Noon,’ hardly ever produce viable seeds. These, however, make up a relatively minor portion of the entire peony population; the vast majority of Chinese and Japanese tree and herbaceous peonies all produce copious amounts of healthy seeds that are quickly ready for harvesting and sowing.
The lovely star-shaped pods are currently growing and starting to change from a leathery green to a brown hue. When the seedpod has turned a dark tallow-brown, the seeds are ready to be picked. Between the first and third weeks of August, we often harvest our tree peony seeds here.
The seeds are ripe and prepared for harvesting when the seed pods have turned a dark brown hue and are just starting to crack open. Carefully pry open each section of the seed pod to release the seeds. Seeds with damage won’t grow.
Peony seeds go into a twofold dormancy when fully ripe, consisting of a hard outer seed coat and a dormant embryo. When water and air can get past the seed coat and into the embryo, germination happens.
Starting peony seeds can be done in a variety of ways. Some are based on the seed’s natural state, or degree of dormancy, while others are determined by the grower, namely whether to sow the seeds outdoors or indoors.
Freshly harvested seeds that have not yet had a chance to fully form a hard outer coat may germinate during the same growing season (late fall) and sprout the next spring as a tiny green stem above the earth. It may take two growing seasons for seeds with stiff, dry seed coats to break their natural double dormancy when planted directly.
Each beautiful pearl contains the embryo of a peony that has never bloomed before and has the potential to astound spectators for many decades to come. Plant some peony seeds this fall to make the world a more lovely place.
When seedpods are left to mature, they will turn a dark brown, and the seeds inside will turn black. In addition, the seedpods will break open. Black seeds may surprise you next spring, but they are likely to take two seasons to germination and growth. Tan colored seeds have a higher chance of producing sprouts the first spring after planting.
Fresh (tan or black) seeds should be sown immediately in sandy loam, garden soil, perlite, or aged bark nuggets for drainage. The pH should be close to 7.0, which frequently requires adding garden lime to make the soil more palatable. Either plant directly in a seed bed or use 10–12 diameter pots with sufficient drainage holes. For seeding, plastic pots are acceptable although we prefer clay pots or root control bags.
If everything is in place, the seed will sprout in the warm late summer weather, and the cooler fall temps will encourage root growth until the weather turns icy. Nothing will emerge above the soil until the next spring. Some seeds won’t begin to sprout until the next spring. Do not rush anything.
When the ground has thawed in the spring, remove the mulch from the pot and submerge it in the garden. By May, look for any new growth. During the growing season, which runs from April to September, young sprouts need to be watered and fed a moderate liquid fertilizer, such as Neptune’s Harvest fish-seaweed fertilizer, every other month. Young sprouts are around two inches tall.
Only transplant young seedlings in the fall. Till September of their first year, let them develop unmolested. After the first year, the garden should be spaced about six apart.
The tree peony seedlings reach a height of over 6 inches when they have genuine leaves by their second year.
In the fall of their third year, young plants may be relocated once more to a more permanent site. For each plant, allow at least 4 to 5′ (3 for herbaceous peonies), and select a well-drained location with 5 to 6 hours of sun. Usually, tree peony seedlings begin to blossom in their fourth year. Herbaceous plants occasionally bloom in their third year. Remember that peonies occasionally display their mature form after several years of immature blossoms.
The Northwest Cultivar group Chinese (P.rockii) tree peonies, such as “Snow Lotus,” and herbaceous peonies respond exceptionally well to this “direct” sowing technique. The benefits of the processes outlined below may make it easier for seeds from different hybrid groupings of tree peony to germinate.
As previously said, crack open newly gathered seed pods. Some gardeners choose to let seed pods cure in brown paper bags for a week in your garage or another dark, dry, and cool area rather than opening the pods right away after harvest. Carefully open the seedpods after a week.
Put the seeds in a zip-top bag with vermiculite or fine sand that is just slightly wet. Place the bag in a warm location (around 80 degrees). We make use of the refrigerator’s top. The sprouted seeds can be planted outside as indicated above or placed in a refrigerator for a period of cold stratification of 3 months at 40 degrees when root growth begins, which may happen in 4-12 weeks (the vegetable crisper of the refrigerator is a good spot).
seedlings of the herbaceous peony. If it’s still early in the fall, you can either plant these outside or store them in the refrigerator for a period of cold stratification.
The sprouting seeds can then be put in pots and nurtured either indoors with lights or outdoors gradually exposed to natural sunshine. The projecting rootlet should be handled carefully while planting because it is quite delicate. Repeat the three months of warm treatment (at or near 80 degrees), followed by the three months at 40 degrees, if seeds don’t germinate after the first cycle of hot/cold stratification.
Peony seeds with a hard, dry seed coat and a black or dark brown tint are fully dormant. It will probably take two growing seasons for the ideal mixture of water, heat, and bacteria to break down the seed coat and allow water and air to access the embryo if these seeds are sown outdoors without any particular care.
Dry, black seeds need to experience warmth followed by a winter frost (either real or simulated) in order to germinate without extra care.
The seeds could be scarified to hasten germination. This is a technique for physically dissolving the seed coat’s outer layer. We work with a rough file.
Give the seed 2-3 light passes with the file while holding it between your thumb and forefinger.
It only takes a few of gentle passes with the file; going too far will harm the embryo. You have gone too far if you file the seed all the way to the point of the white inside. Filing to get rid of the outer layer of sight is generally sufficient. Only a little portion of the seed needs to be filed. A significant quantity of seeds can be scarified using a diluted sulfuric acid solution.
All that is required to let air and moisture to reach the dormant embryo and begin germination is to fill in just below the shiny external covering.
Seeds can be sown soon after scarifying if it’s still early in the fall and the ground is suitable for planting.
If planting indoors, adhere to the warm/cold stratification guidelines in the section on planting new seeds.
Other things to think about while buying peony seeds:
- Flowers that are single or semi-double typically produce more seeds than intricate double varieties.
- If you can’t plant straight away, store in a cool, dry place.
- It’s possible that the seeds you collect from a single tree peony specimen that’s not close to any other tree peonies won’t grow.
