If you’ve ever wondered whether you can grow peonies from cuttings, the answer is a little more complicated than with herbs or shrubs.

Unlike plants such as lavender or roses, most garden peonies cannot be propagated successfully from stem cuttings.

Instead, they are usually propagated by dividing mature plants. However, there are a few exceptions, and it’s helpful to understand the best way to grow more peonies.

Can You Grow Peonies from Cuttings?

For most herbaceous peonies (Paeonia lactiflora), the answer is no.

These peonies grow from thick underground storage roots, and stem cuttings rarely develop new root systems.

Tree peonies, however, can sometimes be propagated from semi-hardwood cuttings, although success rates are low and the process requires patience.

For home gardeners, division is by far the easiest and most reliable method of propagating peonies.

The Best Way to Propagate Peonies

If you want more peonies in your garden, dividing an established plant is the recommended method.

Division allows you to:

  • Grow identical new plants
  • Rejuvenate older clumps
  • Expand your flower beds
  • Share peonies with friends and family

When to Divide Peonies

The best time is:

  • Early fall
  • About 4–6 weeks before the ground freezes

At this time, the plant is entering dormancy and can establish new roots before winter.

How to Divide a Peony

Step 1: Dig the Plant

Carefully dig around the entire clump.

Lift the root ball without damaging the thick storage roots.

Step 2: Wash Away the Soil

Rinse the roots so you can clearly see the growth buds, often called “eyes.”

Step 3: Divide the Roots

Using a clean, sharp knife:

  • Cut the root into sections.
  • Each division should have 3–5 healthy eyes.
  • Include several thick roots with each division.

Step 4: Replant Immediately

Plant each division:

  • In full sun
  • In rich, well-drained soil
  • With the eyes only 1–2 inches below the soil surface

Planting too deeply is one of the most common reasons peonies fail to bloom.

Can Tree Peonies Be Grown from Cuttings?

Tree peonies can occasionally be propagated from cuttings, although the process is slow and less reliable.

If you’d like to try:

  • Take a semi-hardwood cutting in midsummer.
  • Remove the lower leaves.
  • Dip the stem in rooting hormone.
  • Plant it in a well-draining propagation mix.
  • Keep humidity high with a humidity dome or plastic cover.
  • Place the cutting in bright, indirect light.

Rooting may take several months, and success rates vary.

Caring for Newly Divided Peonies

After planting:

  • Water deeply.
  • Apply a light layer of mulch.
  • Keep soil evenly moist during the first growing season.
  • Avoid heavy fertilizing.

Most newly divided peonies establish quickly but may take one to three years to produce abundant blooms.

Common Mistakes

Planting Too Deep

Peony eyes should be only 1–2 inches below the soil surface.

Dividing Plants That Are Too Young

Wait until peonies are at least 3–5 years old before dividing.

Dividing in Spring

Spring division often stresses the plant and delays blooming.

Overwatering

Peonies dislike soggy soil.

Choose a location with excellent drainage.

Frequently Asked Questions

Can herbaceous peonies grow from stem cuttings?

Generally, no. Division is the recommended propagation method.

Can tree peonies grow from cuttings?

Yes, but success rates are lower than with division or grafting.

How long does it take new peonies to bloom?

Most divided peonies bloom within one to three years.

Should I use rooting hormone?

Rooting hormone may improve success with tree peony cuttings but isn’t needed when dividing herbaceous peonies.
