Peonies are stunning, long-lasting flowers that bring beauty to any garden. However, as they grow older, they may stop blooming as abundantly. Dividing peonies helps refresh the plant, promoting better growth and more flowers in the future.
This simple process not only improves the health of your peonies but also allows you to create new plants for your garden. In this guide, we’ll walk you through the easy steps to divide and replant peonies, ensuring they thrive for many more years.
Why Should You Divide Peonies?
Dividing peonies helps the plant grow better. Older plants often stop blooming as much, and dividing them gives the roots more space. It also helps avoid overcrowding in the garden.
You can also grow more plants by dividing one big peony into smaller ones. These new plants can be moved to other spots or shared with friends. It’s a great way to enjoy more peonies without buying new ones.
When Is the Best Time to Divide Peonies?
The best time to divide peonies is in the fall. This is usually around September or October. By then, the leaves have started to die back, and the plant is getting ready to rest for the winter.
Dividing them in fall gives the roots time to settle before winter. They’ll be ready to grow again in spring. Avoid dividing in summer or spring, as it can stress the plant too much.
What Tools Do You Need?
To divide peonies, you don’t need many tools. A sharp spade, garden fork, and a clean knife are enough. Make sure your tools are clean to avoid spreading disease.
You might also want gardening gloves to protect your hands. Keep a bucket of water nearby to rinse the roots. Having everything ready will make the job easier and quicker.
How to Prepare the Peony for Division
First, cut the peony stems down to about 2–3 inches above the ground. This makes the plant easier to handle. You can use clean garden shears or scissors for this.
Next, gently dig around the plant to loosen the soil. Try not to damage the roots. Lift the whole root clump out of the ground carefully with a garden fork or spade.
How to Divide the Root Clump
Wash the roots gently with water so you can see what you’re doing. You’ll notice thick roots with small buds, called “eyes.” These eyes are where new stems grow in spring.
Use a clean knife to cut the root clump into sections. Each section should have 3–5 eyes and some healthy roots. This gives each new plant a good start for the next growing season.
How to Replant Divided Peonies
Pick a sunny spot with well-drained soil for planting the new sections. Peonies love full sun and don’t like wet feet. Dig a hole that is wide and deep enough for the roots to spread.
Place the root section in the hole with the eyes facing up. The eyes should be about 1–2 inches below the surface. Fill the hole with soil, press gently, and water well.
How to Care for Peonies After Dividing
Water the new plants well after planting. Keep the soil moist but not soggy. This helps the roots settle in their new home.
You won’t see many flowers in the first year. That’s normal. Peonies take time to adjust. Be patient, and you’ll see beautiful blooms in the following years.
Common Mistakes to Avoid
Don’t plant the peony roots too deep. If the eyes are buried more than 2 inches, the plant may not bloom. Always double-check the depth when planting.
Also, don’t divide the plant too often. Once every 8–10 years is enough. Peonies don’t like being moved too much, so give them time to grow and settle.

Conclusion
Dividing peonies is a simple way to keep your plants healthy and thriving. It helps improve blooming, prevents overcrowding, and gives you more peonies to enjoy or share. The best time to divide them is in the fall, using clean tools and careful steps.
Make sure each new section has healthy roots and several eyes for strong growth. Plant them in a sunny spot with well-drained soil, and be patient as they settle in. With a little care and attention, your divided peonies will reward you with beautiful blooms for many years to come.
