Spring planning: When is the best time to plant peonies?

The best time to plant peonies is a question that occupies many gardeners. These beautiful flowers add color to any garden. However, there's more to planting and caring for peonies than you might think. With the right knowledge, you can enjoy years of vibrant blooms and healthy plants. This blog post explains exactly how to plant, care for, and propagate peonies.

Peony varieties and their differences

Peonies are roughly divided into two groups: herbaceous peonies and tree peonies. Herbaceous peonies die back above ground in winter and reappear in spring. Tree peonies have woody stems that remain above ground in winter. They often grow much larger than regular peonies. Tree peony flowers appear from mid-April to June and are often red or yellow. A mature tree peony can reach a height of 1.75 meters, making it a real wow factor in the garden.

Herbaceous peonies are smaller and very suitable for borders or mixed plantings. Both varieties are beautiful, but differ in height and care.

The right time to plant peonies

Peonies can be planted in both autumn and spring. Autumn is often preferred because the plant can establish roots throughout the winter. This gives the peony a strong foundation in spring and a greater chance of abundant blooms. However, spring is also fine, as long as the soil isn't too wet or too cold.

When planting in spring, it's important to water the plant thoroughly right away. This allows the roots to establish more quickly. In autumn, extra watering is less necessary, but you should still check the soil.

How to plant peonies: in the ground or in a pot

Peonies can be planted either directly in the ground or in a large pot. Both methods have their advantages. In the ground, peonies have plenty of room to grow. Not everyone has space in the ground. By planting them in a pot, you can also enjoy the beautiful, colorful flowers. Moreover, you can easily move them around in the pot. Below, you'll find a step-by-step explanation of both options.

Planting peonies in the open ground:

• Dig a hole 10 to 15 centimeters deep and twice as wide as the root ball.
• Loosen the soil so that the roots can grow well.
• Mix the excavated soil with compost or manure for better soil structure.
• Place the rhizome in the hole. Make sure the "eyes" are no deeper than 5 centimeters (2 inches) below the surface.

·         Maintain sufficient distance between the plants, about 90 to 120 centimeters. This gives them room to fully develop and prevents mold.

·         Backfill the hole and press the soil firmly.

·         Water the plant when planting so the roots absorb nutrients immediately. Continue watering regularly during dry periods, but avoid allowing the soil to become too wet .

Planting peonies in pots:

• Choose a large pot of at least 40 to 50 centimeters in diameter with holes for drainage.
• Fill the pot with airy potting soil and, if necessary, mix in sharp sand or perlite for good drainage.
• Place the rhizome in the pot with the 'eyes' no more than 5 centimetres below the ground.
• Fill the pot with potting soil and press the soil lightly.
• Place the pot in a sunny spot where the plant will get at least six hours of light.
• Water regularly , but avoid allowing the soil to remain constantly wet.

Location and sunlight for peonies

A peony grows best in a bright spot. Ideally, it should receive at least six hours of sunlight per day. The more sun, the more abundant the blooms. If you place the peony in a shady spot, fewer flowers will appear.

Also, make sure the soil drains well. Peonies don't like wet feet. Therefore, choose loose soil and avoid areas where water stagnates.

Pruning peonies in the fall

September and October are the best times to prune your peonies. Remove old and discolored stems. Always leave at least two strong stems so the plant can sprout again next year.

Is the peony growing too large? Then you can remove older branches. Leave the younger stems. That way, it will bloom profusely again later.

When does the peony bloom?

Peonies bloom from mid-April to mid-June. During this period, you'll enjoy beautiful, large flowers that brighten up your garden. Depending on the variety, the colors can range from white to deep red.

During this period, provide sufficient water and keep weeds away from the plant. This will ensure the roots receive all the nutrients they need and promote longer flowering.

Are peonies winter hardy?

Fortunately, peonies are winter-hardy. So they can stay in the garden, even during cold nights. However, the above-ground parts die back in winter. The plants will sprout again in spring.

Protection is usually not necessary, except for young plants. In that case, you can spread some mulch or leaves around the roots. This provides extra protection during severe frost.

Colors and symbolism of peonies

Besides their beauty, peonies also have a rich symbolism. In many cultures, they symbolize love, wealth, and prosperity. This makes them beloved not only for gardens but also as gifts.

The flowers are available in a variety of colors, from bright white to deep pink and deep red. Each color gives the garden its own unique atmosphere.

Combine with other plants in the garden

Peonies are real eye-catchers, but they look even better with the right companions. Pair them with lavender, for example, for a beautiful contrast of color and scent. Ornamental grasses also create a playful effect alongside the full blooms.

Flower bulbs like tulips or daffodils perfectly complement the peony blooming season. This way, you can enjoy color early in the spring, followed by the rich blooms of the peony.

Tips for longer flowering and healthy plants

A vigorously growing peony will produce abundant flowers for years. These steps will ensure abundant blooms and keep the plant healthy.

1. Cut off faded flowers: Remove the spent buds immediately. Cut back to just above a pair of healthy leaves.
2. Fertilize lightly in spring: Use organic fertilizer in March or April. Apply sparingly to prevent soft growth.
3. Water regularly: Keep the soil slightly moist during the growing season. Avoid puddles and wet roots.
4. Apply a mulch layer: Spread a thin layer of compost around the plant in April. Mulch retains moisture and nourishes the soil.
5. Provide plenty of sun and air: Choose a spot with at least six hours of sun per day. Allow plenty of room for air circulation.
6. Support heavy stems: Place stakes or stakes on large varieties in good time. This will keep the flowers upright.
7. Keep the leaves clean and healthy: Remove diseased or brown leaves immediately. Clean your pruning shears after use.
8. Prune carefully in the fall: Cut away unsightly stems in September or October. Leave at least two strong stems.
9. Don't transplant unnecessarily: It's best to leave peonies in the same spot for years. They don't like being moved frequently.
10. Divide older plants when necessary: ​​Divide large clumps in autumn or early spring. Ensure each section produces three shoots and strong roots.
11. Don't feed too much nitrogen: Avoid high doses of fast-release fertilizer. Too much nitrogen produces foliage but fewer flowers.
12. Protect from extreme drought or heat: Provide plenty of water during warm periods. Temporarily protect with fleece if necessary.

This routine will help your peony grow strongly, resulting in fuller, longer blooms each year.

Peonies as cut flowers

Peonies are incredibly popular in bouquets. Cut the stems when the buds are still half closed. This way, they'll last longer in the vase.

Always use a clean vase and fresh water. Cut the stems diagonally for better water absorption. This way, you can enjoy the peony's full splendor indoors, too.

Propagating peonies by division

Want more peonies in your garden? You can divide older plants. Do this in early spring or autumn. First, cut away dead stems and divide the root ball. Each division should have at least three shoots and plenty of roots.

After dividing, you can replant the pieces in a suitable location. Tree peonies cannot be propagated this way because they have woody stems.

Frequently asked questions about peonies

How long can a peony stay in one place?
Peonies can grow in the same spot for decades. Transplanting is usually not necessary.

Why isn't my peony blooming?
This can be caused by planting too deep, not enough sun, or plants that are too young. Sometimes it takes several years for flowering to occur.

Can you plant peonies in the shade?
They do grow in shade, but produce fewer flowers. Sunlight is essential for abundant flowering.
