How to propagate peonies
If you have a love for beautiful, fragrant blooms, then peonies are a must-have in your garden. Peonies are perennial plants that produce stunning flowers in a range of colours, including shades of pink, red, and yellow. While peonies can be purchased as mature plants, there is nothing more rewarding than propagating your own.
Propagation is the process of growing new plants from the ones you already have. It allows you to expand your peony collection and share your favourite varieties with friends and family. Plus, it’s a budget-friendly way to enjoy a garden full of these gorgeous flowers. So, if you’re ready to get your hands dirty and learn how to propagate peonies, read on!
There are several methods of propagating peonies, including division, root cuttings, and grafting. In this article, we will focus on the most common and straightforward method: division. Division involves separating the root clumps of mature peony plants into smaller segments, each with at least one bud and a few roots. It’s best done in early autumn when the peony plants are still dormant.
Growing peonies from seeds
If you want to start propagating peonies from seeds, here is what you need to know:
1. Collecting and preparing seeds:
Peony seeds are typically harvested in the fall after the flowers have faded and the seed pods have dried out. Collect the seed pods and open them to retrieve the black, round seeds. Remove any leftover flesh from the seeds and let them dry thoroughly.
2. Cold stratification:
Peony seeds require a period of cold stratification to break their dormancy and stimulate germination. Place the dry seeds in a plastic bag with a moist paper towel and seal it. Put the bag in the refrigerator and leave it there for about 60 to 90 days.
3. Starting seeds in containers:
Fill a seed tray or container with a well-draining potting mix. Add the cold-stratified peony seeds on the surface and cover them with a thin layer of the potting mix. Mist the soil lightly to moisten it.
4. Providing optimal growing conditions:
Place the container in a warm location with indirect sunlight. Keep the soil consistently moist, but avoid overwatering which can lead to fungal diseases. Germination may take several weeks or even a couple of months.
5. Transplanting seedlings:
Once the seedlings have developed several sets of true leaves, they can be transplanted into individual pots or directly into the garden. Choose a sunny location with well-draining soil.
Note: Growing peonies from seeds can be a patience-demanding process as it takes a few years for the plants to reach maturity and produce flowers, but it can also be a rewarding journey of witnessing the whole growth cycle of these beautiful flowers.
Preparing the seeds
Propagating peonies from seeds can be a rewarding and exciting process. However, keep in mind that peony plants grown from seeds may take several years to bloom. Nevertheless, if you’re up for the challenge, here’s how you can prepare the seeds for planting.
1. Harvesting the seeds
Wait for the peony blooms to fade and wither. Once they do, you can harvest the seed pods. These pods are usually green and plump right after flowering but will turn brown and split as they mature. This indicates that the seeds are ready for harvesting.
Carefully cut the seed pods from the peony plants using a clean, sharp pair of scissors or pruners. Place the pods in a paper bag, allowing them to further dry for a couple of days.
2. Extracting the seeds
After the seed pods have dried and split, gently shake and open them to release the peony seeds. Make sure to do this above a clean surface to catch any loose seeds. To separate the seeds from any remaining debris, you can lightly blow on them or use a small, soft brush.
It’s important to note that peony seeds are coated with a waxy substance that inhibits germination. To increase their chances of sprouting, you’ll need to remove this coating. You can do this by soaking the seeds in warm water for about 24 hours, stirring occasionally. The water will turn slightly murky as the waxy coating softens and dissolves.
After the soaking, drain the water and rinse the seeds with clean, fresh water. Pat them dry with a paper towel or allow them to air dry for a short period of time. At this point, the peony seeds should be ready for planting.
Note: It’s important to mention that peony seeds may not produce plants with traits identical to their parent plant. They usually result in variations and may take several years to mature into blooming plants.
Division of peony clumps in early spring
In early spring, dividing peony clumps is an essential process to ensure healthy growth and flowering. Dividing peony clumps every few years helps rejuvenate the plant, encourages better airflow and reduces the risk of diseases. Follow these steps to successfully divide your peony clumps:
1. Choose the right time
The best time to divide peony clumps is in early spring, just as the new shoots are beginning to emerge. This usually occurs in March or April, depending on your climate. Dividing peonies at this time ensures that the plant has enough time to establish itself and bloom later in the season.
2. Prepare the tools
Before dividing peonies, make sure you have a sharp garden spade or a garden fork, a pair of sharp pruning shears, and a bucket or a tarp to place the divided clumps.
3. Dig up the clump
Start by digging around the entire clump, about 8-12 inches away from the center. Carefully lift the entire plant from the ground, trying not to damage the roots. Place the clump on the tarp or in the bucket.
4. Divide the clump
With a sharp garden spade or a garden fork, carefully divide the clump into smaller sections. Make sure each section has at least three to five strong, healthy-looking tuberous roots. It is important to ensure that each section is of sufficient size and has enough buds to ensure successful growth.
5. Clean and plant the divisions
Trim back any damaged or dead roots, as well as any diseased or insect-infested sections with sharp pruning shears. Prepare a well-draining planting site in a sunny or partially shaded location, ensuring that each division has ample space for growth. Plant the divisions with the bud eyes facing upwards and cover them with soil, making sure the soil level is even with the top of the root division.
Note: Avoid planting the divisions too deep, as this can inhibit their growth and flowering.
6. Water and mulch
After planting the divisions, water them thoroughly to encourage the initial root establishment. Apply a layer of organic mulch, such as shredded bark or compost, around the newly planted divisions. Mulching helps retain moisture, suppress weeds, and regulate soil temperature.
By following these steps, you can successfully divide your peony clumps in early spring and promote healthy growth and abundant flowering.
Digging up the clumps
When it comes to propagating peonies, one of the steps involved is digging up the clumps. This process is usually done in the fall after the plants have finished blooming.
Here are the steps to follow when digging up the clumps:
Step 1: Prepare for digging
Before you start digging, make sure to cut back the foliage to about 4 inches above the ground. This will make it easier to see and access the clumps.
Step 2: Mark the location
Use a string or garden markers to mark the location of the clumps. This will help you find them later when it’s time to replant or divide them.
Step 3: Loosen the soil
Using a garden fork or shovel, carefully loosen the soil around the clumps. Start digging around the outer edge and work your way inwards. Be careful not to damage the delicate roots.
Step 4: Lift out the clumps
Gently lift the clumps out of the ground using your hands or a garden fork. Shake off any excess soil or gently rinse the roots under water to remove dirt.
At this point, you can choose to divide the clumps to create new plants or simply replant them as they are. This decision will depend on your specific goal for propagating peonies.
Remember to handle the clumps with care to avoid any damage, as peony roots are sensitive and can easily break.
A good practice is to replant or divide the clumps immediately after digging them up. However, if necessary, you can store them temporarily in a cool and dry location until you are ready to propagate.
Tip | When dividing the clumps, make sure each new division has at least three to five healthy buds. This will help ensure successful growth and blooming. |

By following these steps, you will be able to successfully dig up the clumps of your peonies in preparation for propagation. Remember to take your time and handle the plants with care to ensure the best results.
Separating the roots and shoots
When propagating peonies, it’s important to separate the roots and shoots properly to ensure successful growth. Here are the steps to do this:
Gather the necessary tools
Before you begin separating the roots and shoots, make sure you have the following tools:
- Sharp and clean knife or garden shears
- Gloves to protect your hands
- A container or pot filled with well-draining soil
Steps to separate the roots and shoots
Follow these steps to properly separate the roots and shoots:
- Carefully dig up the peony plant, making sure to dig around the root ball to avoid damage.
- Gently shake off excess soil to expose the roots and shoots.
- Inspect the root system to find natural points of division.
- Using a sharp and clean knife or garden shears, carefully cut the root mass into sections, making sure each section has at least three to five healthy shoots.
- Make clean cuts, removing any damaged or diseased parts of the roots.
- Fill a container or pot with well-draining soil, leaving enough room for root growth.
- Plant each section in the container, making sure to bury the roots and shoot buds at the appropriate depth.
- Water the newly separated plants thoroughly to help them establish into the soil.
By separating the roots and shoots of peonies properly, you’ll not only propagate new plants but also ensure their healthy growth and longevity.
Propagating peonies through cuttings
Peonies can also be propagated through cuttings, which is an effective and relatively simple method. This method allows you to create new plants that are genetically identical to the parent plant. Here are the steps to propagate peonies through cuttings:
- Choose a healthy stem: Look for a strong and healthy stem on the peony plant. It should be green, firm, and free from any signs of disease or damage.
- Prepare the stem: Using a sharp and clean pair of pruning shears, cut a 4-6 inch section of the stem just below a set of leaves. Make sure to remove any leaves or flowers from the bottom 1-2 inches of the stem.
- Dip in rooting hormone: Dip the bottom end of the cutting into a powdered rooting hormone. This will help stimulate root development and increase the chances of successful rooting.
- Plant the cutting: Fill a small pot or container with a well-draining potting mix. Make a hole in the soil using a pencil or your finger, and place the cutting in the hole. Gently press the soil around the stem to secure it in place.
- Water the cutting: Give the cutting a thorough watering using a spray bottle or a gentle stream of water. The soil should be moist but not waterlogged.
- Provide the right conditions: Place the pot in a warm and bright location, but away from direct sunlight. Keep the soil consistently moist by watering the cutting regularly.
- Wait for roots to develop: It may take a few weeks or even months for roots to develop. You can gently tug on the cutting to check for resistance, which indicates the presence of roots.
- Transplant the rooted cutting: Once the cutting has developed a good root system, you can carefully transplant it into a larger pot or directly into your garden. Make sure to provide the new plant with proper care and continue to water it regularly.
Tips for success:
- Choose a stem that is from current year’s growth for best results.
- Keep the cutting away from strong winds or extreme temperatures, as these can hinder rooting.
- Make sure the potting mix is well-draining to prevent waterlogging, which can cause root rot.
- Consider covering the cutting with a plastic bag or using a mini greenhouse to create a more humid environment, which can enhance root development.
- Be patient and check on the cutting regularly. It may take some time for roots to form, but with proper care, you should see signs of successful rooting.
Taking root cuttings in late autumn
Propagating peonies by root cuttings is an effective way to expand your peony garden. Late autumn is the perfect time to take root cuttings, as the peonies have gone dormant and the root system is more manageable.
Here are the steps to take root cuttings:
- Start by selecting a healthy peony plant with strong growth and well-developed roots.
- Using a sharp, clean knife, cut a portion of the root system that is about 3-4 inches long.
- Make sure the root cutting has several prominent buds or “eyes”.
- Prepare a pot or container with a well-draining soil mixture.
- Place the root cutting vertically into the soil, ensuring that the buds are facing upwards.
- Cover the root cutting with a layer of soil, leaving the buds exposed.
- Water the pot thoroughly and place it in a cool, shaded area.
- Maintain moist soil by watering regularly, but avoid overwatering.
- Keep the pot protected from extreme temperature fluctuations.
- After the winter period, the root cutting will develop new roots and shoots.
- Transplant the new peony plant into your garden in early spring.
By taking root cuttings in late autumn, you can easily propagate peonies and expand your collection of these beautiful flowering plants.
