The Art of Growing Pink Peonies: A Gardener’s Guide

Pink peonies are a beloved addition to any garden, known for their large, fragrant blooms and lush foliage. These perennials are not only beautiful but also relatively easy to care for, making them a favorite among both novice and experienced gardeners. This comprehensive guide will delve into everything you need to know about growing pink peonies, from selecting the right variety and planting to caring for them and addressing common problems.

Introduction to Pink Peonies

History and Origin

Peonies have a long history that dates back thousands of years, with origins in Asia, Europe, and Western North America. They have been cultivated for their beauty and medicinal properties since ancient times. Pink peonies, in particular, are highly prized for their romantic and elegant appearance, symbolizing love, prosperity, and honor in various cultures.

Varieties of Pink Peonies

There are three main types of peonies: herbaceous, tree, and intersectional (Itoh). Each type has its own unique characteristics and growing requirements.

Herbaceous Peonies: These are the most common type, with bushy plants that die back to the ground each winter. Popular pink varieties include ‘Sarah Bernhardt’, ‘Bowl of Beauty’, and ‘Monsieur Jules Elie’.
Tree Peonies: These have woody stems and do not die back in winter. They produce large, spectacular blooms. Pink varieties include ‘Hana-Kisoi’ and ‘Kamata-nishiki’.
Intersectional (Itoh) Peonies: These are a hybrid between herbaceous and tree peonies, offering the best of both worlds. They have sturdy stems and large blooms. ‘Pink Double Dandy’ is a notable pink variety.

Planting Pink Peonies

Choosing the Right Location

Peonies thrive in well-drained soil and full sun, although they can tolerate partial shade. When selecting a location, consider the following:

Sunlight: Peonies need at least 6-8 hours of direct sunlight per day. Morning sun is preferable as it helps dry the dew on the leaves, reducing the risk of disease.
Soil: Peonies prefer fertile, well-drained soil with a pH of 6.0-7.0. Heavy clay soils should be amended with compost or peat moss to improve drainage.
Space: Peonies need room to grow. Plant them about 3-4 feet apart to ensure adequate air circulation and space for their roots to expand.

Preparing the Soil

Before planting, prepare the soil by incorporating organic matter such as compost or well-rotted manure. This will improve soil structure, fertility, and drainage. If your soil is particularly heavy or sandy, consider conducting a soil test to determine any additional amendments needed.

Planting Peony Roots

The best time to plant peony roots (also known as bare-root peonies) is in the fall, typically from late September to early November. Follow these steps for successful planting:

Digging the Hole: Dig a hole about 12-18 inches wide and deep. This allows room for the roots to spread out.
Adding Amendments: Mix in compost or other organic matter with the excavated soil.
Positioning the Root: Place the peony root in the hole with the “eyes” (buds) facing upwards. The eyes should be no more than 1-2 inches below the soil surface. Planting too deep can prevent blooming.
Backfilling: Gently backfill the hole with soil, pressing down lightly to eliminate air pockets.
Watering: Water thoroughly to help settle the soil around the roots.

Planting Peony Transplants

If you are planting peony transplants, follow these steps:

Digging the Hole: Dig a hole large enough to accommodate the root ball.
Positioning the Plant: Place the transplant in the hole at the same depth it was growing in the pot.
Backfilling: Fill in with soil, pressing down lightly to remove air pockets.
Watering: Water thoroughly to establish the plant.

Caring for Pink Peonies

Watering

Peonies require regular watering, especially during their first year of growth and during dry spells. Here are some watering tips:

Consistency: Keep the soil consistently moist but not waterlogged. Overwatering can lead to root rot.
Deep Watering: Water deeply to encourage deep root growth. This is particularly important during the establishment phase.
Mulching: Apply a layer of mulch around the base of the plant to help retain moisture and regulate soil temperature.

Fertilizing

Peonies benefit from regular feeding to promote healthy growth and abundant blooms. Use a balanced, slow-release fertilizer in early spring when new growth begins. Follow these guidelines:

Early Spring: Apply a balanced 10-10-10 fertilizer around the base of the plant, avoiding direct contact with the stems.
Mid-Season: A second application can be made after the plant has finished blooming to support root development.

Pruning and Deadheading

Proper pruning and deadheading are essential for maintaining the health and appearance of peonies:

Deadheading: Remove spent blooms by cutting the flower stem just above a set of healthy leaves. This encourages the plant to focus energy on root development rather than seed production.
Pruning: In late fall, after the first frost, cut back herbaceous peonies to the ground to prevent disease and pests from overwintering. For tree peonies, remove any dead or damaged wood in early spring.

Supporting Peony Plants

Peonies, especially herbaceous and Itoh varieties, can become top-heavy when in full bloom. Support your plants to prevent them from flopping over:

Peony Rings: Install peony rings or stakes around the plants in early spring before they start growing. The foliage will grow through the supports, keeping the blooms upright.
Stakes and Twine: For larger plants, use stakes and twine to create a supportive framework around the plant.

Winter Care

Peonies are hardy perennials, but they still require some winter care:

Mulching: Apply a thick layer of mulch after the ground freezes to protect the roots from extreme cold and temperature fluctuations.
Tree Peonies: For tree peonies, wrap the stems with burlap or another protective material to shield them from harsh winter winds and frost.

Common Problems and Solutions

Pests

Peonies are generally pest-resistant, but they can occasionally be affected by:

Aphids: Small, sap-sucking insects that can cause distorted growth. Control them with insecticidal soap or by spraying with a strong stream of water.
Ants: Often found on peony buds, attracted by the sweet nectar. While ants do not harm the plant, their presence can indicate aphids. Controlling aphids will reduce ant activity.
Thrips: Tiny insects that feed on flower petals, causing discoloration and deformities. Use insecticidal soap or neem oil to manage thrips.

Diseases

Peonies can be susceptible to several diseases:

Botrytis Blight: A fungal disease that causes buds to turn brown and rot. Improve air circulation, avoid overhead watering, and remove and destroy affected plant parts.
Powdery Mildew: A white, powdery fungus that appears on leaves. Provide good air circulation, avoid overcrowding, and apply a fungicide if necessary.
Leaf Spot: Caused by various fungi, resulting in dark spots on leaves. Remove and destroy affected leaves, and apply a fungicide if needed.

Blooming Issues

Peonies may sometimes fail to bloom due to several factors:

Planting Depth: If planted too deep, peonies may not bloom. Ensure the eyes are no more than 1-2 inches below the soil surface.
Light: Insufficient sunlight can lead to poor blooming. Ensure your peonies receive at least 6-8 hours of direct sunlight daily.
Age: Peonies can take a few years to establish and bloom reliably. Be patient and provide consistent care.

Propagation of Pink Peonies

Division

The most common method of propagating peonies is through division. This is best done in the fall, after the plants have finished blooming and the foliage has died back:

Digging Up: Carefully dig up the peony clump, taking care not to damage the roots.
Dividing: Use a sharp knife to divide the clump into sections, ensuring each section has at least 3-5 eyes and healthy roots.
Replanting: Replant the divisions immediately, following the same steps as for planting bare-root peonies.

Seeds

Growing peonies from seeds is a lengthy process that requires patience, as it can take several years for the plants to mature and bloom:

Harvesting Seeds: Collect seeds from mature peony seed pods in late summer or early fall.
Cold Stratification: Peony seeds require a period of cold stratification to germinate. Place the seeds in a moist medium (such as sand or peat moss) and refrigerate for 3-4 months.
Sowing: Sow the seeds in pots filled with a well-draining potting mix. Keep the soil moist and place the pots in a warm, sunny location.
Transplanting: Once the seedlings have developed a few sets of true leaves, transplant them to individual pots or directly into the garden.
