Peonies are known for their stunning blooms and fragrant flowers, making them a beloved choice for gardens. Whether you want to expand your collection or share the beauty of these plants with others, propagation is the perfect way to do so. There are several methods of propagating peonies, including division, root cuttings, and seed sowing.
In this guide, we’ll walk you through the process of propagating peonies step by step. Whether you’re a seasoned gardener or a beginner, these techniques will help you grow new peony plants that will thrive in your garden and bloom beautifully for years to come.
What Are Peonies?
Peonies are perennial flowering plants that thrive in gardens due to their large, beautiful blooms. These plants can be categorized into two main types: herbaceous peonies, which die back each winter, and tree (shrub) peonies, which have woody stems that remain year-round. Peonies come in various colors, such as pink, white, red, and yellow, making them a favorite for flower gardens.
Known for their hardiness and long lifespan, peonies can live for decades when well cared for. Propagating peonies is a wonderful way to share these lovely flowers or expand your collection, all while keeping their genetic characteristics intact.
What Is Peony Propagation?
Peony propagation is the process of growing new plants from an existing peony. This can be done in a few different ways, with the most common methods being division, root cuttings, and sowing seeds. Each technique has its own requirements and can be chosen based on the gardener’s needs and patience.
Propagation is important for increasing the number of plants in your garden, especially if you have a beloved variety of peony that you want to replicate. It’s a simple way to share peonies with others or ensure they keep thriving year after year.

When to Propagate Peonies
The best time to propagate peonies depends on which method you’re using. For division, the ideal time is early spring or late fall when the plant is dormant. This allows the divided sections to settle in before the next growing season and reduces stress on the plant.
For root cuttings, early spring is recommended, just before the plant begins to grow. If you’re propagating from seeds, collect them in late summer or fall after the flowers have finished blooming. Each method has its ideal timing, so it’s essential to plan accordingly.
3 Methods of Propagating Peonies
There are three main methods for propagating peonies: division, root cuttings, and seed sowing. Division is the most popular method due to its simplicity and efficiency. Root cuttings are another good option for increasing the number of plants. Seed sowing is a slower method but offers the potential for new and unique hybrids.
Method 1: How to Propagate Peonies Through Division
Division involves separating a mature peony into smaller sections, each with its own roots and eyes. It is the most common method of propagation and is relatively simple. Dividing peonies allows gardeners to maintain the same variety while increasing the number of plants in their garden.
Dividing Perennial Peonies
When dividing perennial peonies, begin by carefully lifting the plant from the ground. After removing the excess soil, look for healthy sections with at least two or three eyes, which will develop into shoots. Use a sharp knife to divide the plant into sections, then immediately replant each section.
Dividing Shrub Peonies
Dividing shrub peonies is a bit more challenging due to their woody stems. Like perennial peonies, you must ensure that each division contains enough roots and eyes for successful regrowth. This method works best for older, established plants that can be safely divided without harm.
Method 2: How to Propagate Peonies by Taking Root Cuttings
Root cutting propagation involves removing a section of root from an established plant, cutting it into smaller pieces, and planting these pieces to grow new plants. This method can be particularly effective for increasing the number of peonies quickly. It also works well for both perennial and shrub peonies.
- Step 1: Select a healthy, mature root with multiple eyes and cut it into 3-4 inch sections.
- Step 2: Plant the sections in well-drained soil, burying them just beneath the surface.
- Step 3: Water thoroughly and keep the soil consistently moist until new shoots appear.
Root cutting propagation is a fast and reliable method but requires patience as the plants may take a season or more to fully establish themselves.
Method 3: How to Propagate Peonies by Seed
While slower than other methods, propagating peonies from seed is an interesting and rewarding challenge. This method is often used by those who want to create unique hybrids or experiment with different varieties. Keep in mind that it can take several years for a peony grown from seed to bloom.
After harvesting seeds in late summer or early fall, soak them in water for about 24 hours to soften their outer coating. Then, place the seeds in a moist paper towel inside a plastic bag and refrigerate them for 2-3 months to simulate winter conditions. Once stratified, sow the seeds in a tray or directly in the garden.
Replanting Your New Peony Plants
Once you’ve successfully propagated your peonies, it’s time to replant them in their new homes. Choose a location with well-drained, fertile soil and plenty of sunlight. Peonies need space, so make sure to plant them at least 18 to 24 inches apart to allow for proper air circulation and prevent overcrowding.
Water the plants thoroughly after replanting and keep the soil moist but not soggy. Be sure to protect young plants from extreme temperatures and pests, especially during their first growing season. With proper care, they’ll grow strong and healthy.
Plant Care After Propagation
After propagation, caring for your new peonies is crucial to their success. Keep the soil consistently moist, especially during their first season, but avoid waterlogging. Apply a layer of mulch around the base of the plants to retain moisture and suppress weeds.
Peonies thrive in full sunlight, so plant them in an area where they’ll receive at least six hours of direct sunlight each day. Fertilize the plants in early spring before new growth begins and again after the blooms have faded to encourage healthy root development.
Step-by-Step Guide to Propagating Peonies
Here’s a quick step-by-step summary of the propagation process for peonies:
- Lift the Plant: Dig around the base of the peony to lift it out of the soil.
- Make the Roots Visible: Shake off the soil to expose the roots.
- Identify Eyes: Look for the small, bulbous growths on the roots that will sprout into new shoots.
- Cut into Sections: Divide the root ball into sections, each containing at least 2-3 eyes.
- Replant the Sections: Replant the divisions immediately in well-prepared soil, ensuring the eyes are just below the surface.
Propagating Peonies: Tips on Division, Cuttings & Sowing
Each method of peony propagation has its advantages. Division is fast and effective, while root cuttings offer a quicker way to expand your collection. Seed propagation takes the longest but can result in unique plants. Choose the method that best suits your goals and gardening style, and remember that patience is key to success.
If you want to propagate several plants at once, consider using division or root cuttings. For those willing to wait and experiment, seed sowing offers a chance to create a one-of-a-kind peony garden.
Conclusion
In conclusion, propagating peonies is a fulfilling way to expand your garden and enjoy these stunning flowers year after year. Whether you choose division, root cuttings, or seed sowing, each method offers its own set of advantages. Division and root cuttings provide quicker results, while seed propagation allows for the potential of unique, hybrid plants.
With the right care, patience, and attention to detail, your propagated peonies will flourish and reward you with vibrant blooms. No matter the method, growing peonies from propagation ensures a lasting connection to the beauty and elegance of these timeless flowers.
