Peonies are long-lived perennials known for their large, beautiful blooms, strong stems, and classic garden presence. Once established, they can return for many years with very little maintenance, making them a favourite for Canadian perennial borders, cottage gardens, and cut flower gardens.
Peonies are usually planted as bare roots in fall or early spring. The most important step is planting them at the right depth. If peony eyes are planted too deeply, the plant may grow healthy foliage but produce fewer flowers.

When to Plant Peonies
Plant bare root peonies in fall or early spring as soon as the soil is workable.
Fall planting is often ideal because it gives the roots time to settle in before winter. As temperatures cool, the plant can begin establishing underground before strong spring growth begins.
Early spring planting can also work well, especially if the roots are planted shortly after receiving them. Do not let bare root peonies dry out before planting. If you cannot plant right away, keep the roots cool and lightly moist until planting time.
Where to Plant Peonies
Choose a location with full sun for the strongest flowering. In warmer regions, light afternoon shade can help protect blooms from intense heat.
Peonies grow best in fertile, well-drained soil. Avoid low, wet areas where water sits around the roots, as soggy soil can cause problems over time.
Peonies are excellent for:
- Perennial borders
- Cottage gardens
- Cutting gardens
- Front yard flower beds
- Mixed sunny garden beds
- Long-lasting foundation plantings
Choose the planting location carefully. Peonies prefer to stay in one place for many years and usually perform best when left undisturbed.
How to Plant Bare Root Peonies
Before planting, soak bare root peonies in water for a few hours to rehydrate the roots.
Dig a wide planting hole large enough to spread the roots comfortably. Loosen the soil and mix in compost or organic matter if needed to improve soil structure.
Place the root in the hole with the visible buds, also called eyes, facing upward. Position the eyes no more than 2 to 5 cm below the soil surface. This is one of the most important parts of planting peonies. Planting too deeply can reduce flowering.
Backfill with soil, firm gently, and water thoroughly after planting.
Space peonies about 60 to 90 cm apart to allow room for mature growth and good air circulation.
How Deep Should You Plant Peony Eyes?
Peony eyes should sit about 2 to 5 cm below the soil surface.
If they are planted too deep, the plant may still grow leaves, but it may not bloom well. If they are planted too shallow, the roots may be more exposed to temperature changes.
A shallow planting depth is especially important for herbaceous peonies. After planting, water well and allow the soil to settle around the roots.
Caring for Peonies After Planting
Water regularly during the first growing season to help the roots establish. After that, peonies are fairly low maintenance, but they should be watered during long dry periods.
Apply compost or a balanced fertilizer in spring to support strong growth and flowering. Avoid overfeeding with too much nitrogen, as this can encourage leafy growth instead of blooms.
Peonies may not bloom in the first year after planting. This is normal. Many peonies take two to three years to settle in and flower well. Once established, they often bloom more heavily as they mature.
Supporting Peony Blooms
Many peony varieties produce large, heavy flowers. Taller varieties may benefit from a peony ring, cage, or plant support to keep stems upright, especially after rain.
Place supports early in the season while the stems are still short. This allows the plant to grow naturally through the support.
After Peonies Bloom
Remove spent flowers after blooming to keep the plant tidy and prevent energy from going into seed production.
Leave the foliage in place through the growing season. The leaves help the plant build energy for next year’s blooms.
In autumn, once the foliage has yellowed and died back, cut the stems down to ground level. Remove old plant debris from the area to help keep the planting space clean.
Can Peonies Grow in Containers?
Peonies can grow in large containers, but they usually perform best in the ground where their roots have space to establish.
If growing peonies in a pot, choose a large container with excellent drainage. Use a quality potting mix and avoid letting the soil stay waterlogged. In colder climates, container-grown peonies may need extra winter protection because pots freeze more easily than garden soil.

Frequently Asked Questions About Planting Peonies
When is the best time to plant peonies in Canada?
Peonies can be planted in fall or early spring. Fall planting is often preferred because the roots can settle in before winter, but early spring planting also works if the soil is workable and the roots are planted quickly.
How deep should I plant bare root peonies?
Plant bare root peonies with the eyes about 2 to 5 cm below the soil surface. Avoid planting too deeply, as this can reduce flowering.
Why is my peony not blooming?
A peony may not bloom if it is planted too deeply, does not receive enough sun, is too young, or has recently been moved. Newly planted peonies often take two to three years to bloom well.
Do peonies need full sun?
Peonies bloom best in full sun. They can tolerate light afternoon shade, especially in warmer regions, but too much shade can reduce flowering.
Should I cut peonies back after flowering?
Remove spent flowers after blooming, but leave the foliage in place through the growing season. Cut the stems down in autumn after the foliage has yellowed and died back.
Do peonies come back every year?
Yes. Peonies are long-lived perennials and can return for many years when planted in the right location and left undisturbed.
