Should Large, Ancient Peonies Be Split Up?

Peonies are a beloved plant that can be divided every 4 to 5 years, typically in late summer or early fall when they are not actively growing. The process involves digging up the entire plant, dividing the root ball, and replanting the sections. On average, peonies should be divided every 5 to 7 years or when they show of decline. By dividing peonies regularly, you can rejuvenate the plants and promote regrowth.

When dividing peonies, each section should have at least 3 buds and some healthy roots to promote regrowth. It is essential not to place the buds deeper than 2 inches (5.1 cm) in the soil. The best time to divide peonies is in the fall, typically in late September or early October, as this timing allows the plants to establish roots before the ground freezes. Dividing peonies at the right time helps ensure they are healthy and easy to handle during the winter months.

There are several options for propagating peonies, including vegetative division, which allows you to divide the peony’s roots without uprooting the entire plant. Mature peonies may need to be moved if they are in a shady spot or divided if overgrown. They can be dug up, divided, and transplanted 4 to 6 weeks before the soil freezes. Peonies do best in well-drained soil in full sun and need about 3-4 feet of space in the garden.

Herbaceous garden peonies are longlived and do not need regular division, unlike many garden plants. When taking up a plant early in the growing season, it is okay to replant temporarily and lift again in late summer to make divisions and get them replanted. A well-trimmed division allows ample room for new roots to form and existing roots to increase in girth without growing into one another.

If you have a large, old herbaceous peony clump that you would like to propagate, the best way to do this is through dividing the root system. When it’s necessary to move or divide peonies, the best season is autumn.

Should you divide peonies?

Fall is the optimal time to divide and transplant peonies, as they can overtake an area or grow in too much shade. Plants transplanted in the fall have time to establish roots and produce spring blooms. Dig up a clump of roots, separate it from the main plant, and leave healthy stems and leaves attached. Cut divisions with at least three to five buds, called eyes, to grow into next year’s shoots. Plant the divisions approximately 1 inch deep to prevent them from blooming next year. Transplants take about three years to display full blooms.

Do peonies need to be thinned out?

To prevent overcrowding and potential strangulation of peonies, it is recommended that they be thinned out every 10 or 15 years.

What to do with overgrown peonies?

Pruning peonies for winter depends on the type of peony. Herbaceous peonies, the most common in home gardens, should be regularly pruned after the first hard frost in fall. Cut back peonies to 3 inches (8 cm) high or all the way to the ground, and remove dead foliage and debris to prevent pests and diseases from overwintering. Tree peonies have different pruning requirements and produce woody stems, forming a more robust plant structure. As cooler weather arrives, tree peonies drop their leaves, so trimming or cutting back them before winter is not recommended.

Why are my peonies so leggy?

Peonies, a popular plant with numerous types, can become leggy due to lack of sunlight. They have long, dangly stems and few weak, skinny blossoms, which indicate insufficient sunlight. Despite being easy to grow and having few issues during their growth cycle, it is crucial to identify potential problems early on to prevent them from escalating into larger problems. Common issues that could be impacting your peonies this season include leggy stems, few flowers, and a lack of sunlight.

To get your peonies back on the right track, it is essential to address these issues early on and provide adequate care to prevent them from becoming leggy and causing further damage. By doing so, you can prevent small issues from escalating into larger problems and ensure the longevity and beauty of your peonies.

Do peonies multiply on their own?

1. Dig around the peony plant using a sharp spade, ensuring not to damage the roots. Rinse the roots with a hose to remove any dirt and identify the crown buds. Leave the roots in the shade to soften them and make cutting easier.

2. Cut the roots back to about 6 inches (15 cm.) from the crown, as the crown grows into the peony. Each piece should have at least one visible crown bud.

3. Continue dividing peonies until you have as many as possible from the original roots. Plant the pieces in a suitable location, ensuring the buds are not more than 2 inches (5 cm.) under the soil. Store the pieces in peat moss until ready to plant on a warmer day, but don’t store them too long to prevent drying out and preventing growth.

By following these steps, you can propagate peony plants quickly and create many plants in no time. Sign up for the Gardening Know How newsletter to receive a free download of our DIY eBook “Bring Your Garden Indoors: 13 DIY Projects For Fall And Winter”.

How to make peonies bushier?

To increase the number of flowers in a peony bush, it is recommended that the buds be left intact. Should one desire larger flowers at the end of each branch, it is recommended that pruners be used to remove smaller buds on the sides, holding them at a 45-degree angle. Should one desire a greater number of smaller flowers, it would be advisable to remove the larger bud at the extremity of the branch, while leaving the smaller buds intact.

How to keep peonies blooming all summer?

The item is now prepared for refrigeration and has been wrapped in Saran Wrap to prevent moisture loss and maintain its quality, in accordance with the instructions provided.

How often do peonies need to be divided?

Peonies are a type of perennial that rarely require dividing, but if you want to break a mature plant into smaller ones or move an existing one, it is best done in late summer or early fall. Peonies divided in the spring grow poorly, so it is best to wait four to six weeks before hard frost when the leaves begin to look ragged. Cut the roots into sections with at least three prominent eyes, set them in their new spot with the eyes facing up, and set them at a depth of no more than 2 inches below the surface.

This may take two years for the three-eye divisions to become large enough to bloom again. Dividing the plants into larger root pieces will produce bigger plants and flowers sooner. On the ease-of-dividing scale, other perennials fall between the resiliency of daylilies and the fussiness of peonies. However, almost anything can be divided at the end of the season, when the soil is well-warmed, moist, and the sun is less intense, allowing for new root growth.

How do you support heavy peonies?

To support peonies, use 4 to 6 strong stakes around the plant’s perimeter, and consider using metal stakes for older plants. Longfield Gardens offers a variety of planted bulbs, including perennials, indoor bulbs, and specials.

Does cutting peonies encourage growth?

Deadheading faded peony flowers after they’re past their prime doesn’t encourage more flowers like other annuals and perennials. It also redirects energy into next year’s growth and blooms, which is crucial for fertilizing peonies. To deadhead a peony, use sharp pruners to snip flower stems where they meet leaves. Leave the foliage in the garden until autumn, as the plant relies on the energy from the leaves for the following year’s new growth.

The leaves may look less than stellar throughout the season, so it’s important to wait until fall to prune them back, as cutting them sooner could affect next year’s flowers. This article will explain why it’s important to leave herbaceous peony foliage in the garden until fall.
