When In Maine Should I Transplant Peonies?

Peonies are best transplanted during their dormant period in the fall, with mid-August being ideal for Northern regions and early November for Southern gardeners. The gradual increase in daylight hours triggers the plant to grow, making it easier to move them to another spot. In Maine, peonies should be planted in late August or early September, as they are easy and forgiving to grow.

Transplanting peonies in the spring can weaken the root system, so it is best to wait until the plant dies back for winter before moving it or waiting until early spring. Late fall/early spring are the best bet for transplanting established peonies.

In Maine, there are no laws limiting what can be brought into the state for personal yard use, but all laws are based around quarantined plants. Potted peony plants can be transplanted in the spring or fall, and bare root peonies can also be potted in the fall or early winter.

The exact timing of digging, dividing, and moving peonies varies by region, but mid-August for Northern gardeners and early November for Southern gardeners is a general guideline. In September, dig up peonies after they stop growing and before they go dormant. Peonies are hardy from horticultural Zones 4 through 8, and planting, moving, or dividing peony rootstocks only in the right conditions.

When can peonies be divided and transplanted?

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.

When to plant peony in Maine?

Plant peonies in late September and October in most of the U. S. and later in the fall in Zones 7 and 8. If you must move a mature plant, do so when it has gone dormant. Peonies are perennials that return yearly with their beautiful flowers and lush green foliage. With thousands of varieties available, peonies are best planted in autumn for their stunning blooms that bloom from spring to summer. They make magnificent cut flowers and bear lovely, green foliage.

What is the best month to transplant peonies?

Peonies should be transplanted in late August or early September, as they should only be divided or transplanted every ten years or so. It is not necessary to divide them for decades. A sharp spade should be used to create a neat incision around the root mass, after which the plant should be replanted at the same depth as the original planting location. The University of Minnesota Extension has published a bulletin on the subject of dividing perennials, which is applicable to peonies.

Can peonies be dug up and moved?

Peonies can be left in their natural environment for years, but they may need to be moved to improve flowering or redesign a perennial bed or border. Established peonies should be transplanted in September, starting by cutting the stems near ground level and carefully digging around and under each plant. Replanting in a sunny, well-drained site is crucial. Large peony clumps can be divided into sections with at least three to five buds and a good root system.

Smaller divisions may take several years to develop into attractive plants. Peonies thrive in full sun and well-drained soils, so choose a location with at least six to eight hours of direct sun daily. Avoid shady areas near large trees and shrubs. Poorly drained soils can be improved by working in compost, peat moss, or leaf mold.

How do you 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 do you transplant peonies?

In order to maintain the root system, it is recommended to gently shake off soil from the roots in order to make the eyes visible.

Can you move peonies in the summer?

Transplanting peonies can be done during spring or summer, but the chances of success are less likely. The soil must be optimal for roots to adjust and establish in their new location. Peonies thrive in fertile, well-draining soil ranging from 6-7 on the pH scale. To transplant peonies, trim the plant, dig up the entire shrub, and leave 8-10 inches of soil space from the stems. Cut through the root ball, leaving between 3 buds per section. Shake off excess soil and remove dead growth and thread-like roots.

Replant tubers with their growth buds no more than two inches beneath the soil surface, with buds facing upward upon planting. Backfill and firm the soil, and add 1-2 inches of organic mulch to protect the transplant from frost heaves.

Be prepared that the disrupted peony plant may not produce blooms for the first year after transplant. If the transplant was done in September, the best chance at success is possible. Treat peony plants to bone meal or other organic fertilizer, and wait for anticipated blooms. The transplant process can take several years, but the benefits of the transplant are worth the wait.

Do peonies grow better in pots or ground?

Peonies thrive in a variety of soil types, including well-drained clay soil. To ensure optimal growth and bloom, it is essential to provide at least a half day of sun and good drainage. Some gardeners are planting peonies in large patio pots or raised beds, but it is crucial to ensure adequate drainage and watering more frequently than ground planted peonies.

To prepare the planting site, dig a hole about 15 x 15 inches and fill it with spaded soil. Place the peony root downward at any angle, with the ‘eyes’ facing upward. Plant the roots near the surface of the ground with just one inch to two inches of soil on top of the ‘eyes’. Avoid planting the peony roots too deeply, as this can result in foliage growth without flowers.

Newly planted bare root peonies will establish feeder roots when planted in the Fall, and winter freezing temperatures will not affect roots planted in the ground. Potted peonies require a large container with adequate drainage, and the eyes should be covered with only one inch to two inches of soil. Water the potted peonies thoroughly upon planting or transplanting, watering them every couple of weeks during dry weather. Once the fall/winter rains arrive, you may not need to water your peonies until you have dry weather in the spring/summer.

Once a peony plant is several years old, it is fairly drought tolerant, but they do appreciate a good watering every few weeks in hot summers. An established peony plant does not need frequent watering. Fertilize your peony plants early in the spring using a slow release fertilizer, as other fertilizers will burn the foliage. If you are fertilizing potted peonies, use a slow release fertilizer, as other fertilizers will burn the foliage.

Deadhead flower/seed pods after bloom and trim your peony stems to shape the bush as desired. If you want to let seed pods mature, leave them on the stems until they crack open in late summer. Plant the seeds in the ground or potting flats and keep moist until the fall rains come. Some seeds will germinate the following spring, while others will sprout the second spring.

Cut peony stems to ground level in the late fall and remove the stems and leaves from the garden for good sanitation. Do not compost peony leaves and stems. Mulching is not required in the Northwest, but some gardeners in very cold winter climates mulch for the winter, but be sure to remove the mulch in the spring to avoid planting too deeply.

What happens if you don’t divide peonies?

The common misconception that peonies cannot be divided is a misconception. Herbaceous, garden peonies are long-lived and do not require regular division. They can be left for years or decades without any encouragement. Time is the best fertilizer for peonies. The belief that peonies cannot be divided may be due to their lack of need, lack of desire to give them away, or old stories about woodpeckers pecking out the eyes of those who dug the roots. Peonies have medicinal uses, with Paeon being a physician of the Greek Gods and healing Ares and Hades with peony root.

Planting depth is another reason why peonies cannot be divided. If planted too deeply, the shoots will grow but not bloom, which can continue for many years. In summary, peonies can be divided for various reasons, including their long lifespan, lack of need for division, and the importance of planting depth.

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”.

Do peonies like sun or shade?

Peonies require 6-8 hours of sun daily, with some protection from hot afternoon sun in zones 8-9. They thrive in areas with good air circulation to prevent fungal diseases. There are four main types of peonies: woodland peonies, tree peonies, herbaceous peonies, and intersectional peonies. These beautiful perennials bloom around Memorial Day, with some blooms growing up to 9 inches. Peonies are deer- and rabbit-resistant, making them suitable for gardeners who struggle with animals eating their plants. They can be found in old cemeteries or abandoned farmsteads, as they have received little care for years.
