Intersectional (or Itoh) peonies, also known as tree peonies, can grow and bloom from woody stems grown in previous years, especially in warmer Southern climates. When purchasing potted nursery plants, it is best to plant them as soon as possible rather than letting them remain in pots for too long. The main care requirements for growing an Itoh peony include monitoring for damaged or diseased stems as new growth begins in the spring, pruning to promote healthy growth, and cutting back stems to about 2 inches.
Itoh peonies share qualities with both tree and herbaceous peonies, such as large, long stems and an intoxicating aroma. They can be propagated using root division, which is traditionally effective but may cause disturbance. Before cutting, look for buds on the stems that may be forming, as only certain varieties of intersectional peonies have them.
During a propagation cycle (3 to 4 years), the underground stem extends somewhat with tuberous growth and swells with food storage similar in habit. Some buds may be found on the lower parts of the stems, which are not necessary for growth and may be cut or left on the plant.
Itoh peonies have large, long-lasting blooms and strong stems that do not require staking. They also have dark green, lush leaves. Fertilizer is not required as this can make them too leafy at the expense of flowers.
Will peonies grow back if cut down?
In late fall, it is recommended to remove old stems from herbaceous peonies after the first frost turns the foliage yellow, as this indicates the plant has successfully sent its energy to the roots, which will overwinter and grow into a hearty and healthy plant next spring. Discard all cut foliage to prevent gray mold, a fungus that affects peonies and can survive winter months in composted old stems.
Transplanting peonies in the fall is also recommended, as it is the best time to dig around and clear under the roots without damaging the fleshy tubers. Lever the tuber clump out of the ground with a wide spade or pitchfork, planting it in a new location in full sun with well-draining, rich soil. Plant just beneath the soil level and water it well.
Dividing peonies in the fall is also recommended, as large, well-established peonies can be divided to renew growth or make new plants. Cut back the foliage, dig up the root system, shake or dust the dirt off the tuber clump, and cut the clump into sections with three to five eyes and several roots. Replant each piece in its new garden location, placing the buds 1 to 2 inches below the soil surface and watering the new tubers thoroughly.
How to get Itoh peony to bloom?
When selecting a peony planting site, consider the amount of sun, as more sunlight leads to more flowers. Peonies require rich soil, good drainage, and a neutral pH, creating a sandy loam with equal parts sand, clay, and compost. They cannot tolerate wet feet and should not be planted in low-lying areas that retain water. Plant new intersectional peony plants 3 to 4 feet apart on center, approximately 1.
5 feet from any edge or border. Measure the space available for planting and consider the long-term care requirements. Peonies take about three years to mature and live happily with minimal care for decades.
Can you replant cut peonies?
September is the optimal time to transplant established peonies. Cut the stems near ground level, dig around and under each plant, and retain as much root system as possible. Replant the peonies in a sunny, well-drained site. Divide large clumps into sections with at least three to five buds and a good root system. Peonies thrive in full sun and well-drained soils, so choose a location with six to eight hours of direct sun daily. Avoid shady areas near large trees and shrubs. Improve poorly drained soils by working in compost, peat moss, or leaf mold.
Do peonies multiply on their own?
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.
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.
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 do you get fresh cut peonies to bloom?
To speed up the blooming of peonies, remove unnecessary foliage, cut the stems on a sharp angle every 4 hours, and disinfect the tool before use. Place stems in a vase of tepid water containing flower food, but ensure the water is not too warm. Keep the flowers in a warm, bright room, away from direct sunlight and heating vents, to encourage them to open.
If you need peonies open tomorrow, cover them with a large plastic bag to seal in the ethylene gas and place them close to ripe bananas to add more ethylene gas. Peonies are the pick of the season, with full-bodied blossoms, glossy leaves, and a fresh fragrance that will keep guests talking long after they’ve left. They are the most wonderful time of the year, and their full-bodied blossoms, glossy leaves, and fresh fragrance will keep your guests talking long after they’ve left.
How to cut back Itoh peony?
Itoh/intersectional peonies are plants that grow four to five inches above the ground, with certain varieties having side buds. To preserve more flowers and maintain a symmetrical plant, cut them to a consistent height above these buds. Home garden compost should not be used to kill fungal spores and bacteria on peony leaves. Intersectional peonies have flowers similar to tree peonies but longer stems, like their herbaceous parent.
Careful cutting is necessary to avoid cutting the woody portion of the plant that will remain above ground. It is also important not to take more than a third of the leaves at a time when cutting multiple stems. Intersectional peonies produce outstanding cut flowers in unique colors.
Can you grow peonies from cut flowers?
Propagating peonies from cuttings is a simple process, but it requires healthy peonies, secateurs, rooting hormone, plant pots, and well-draining soil. To take cuttings, you can find healthy peonies from friends who can supply them, but always ask before snipping. You can also buy rooting hormone powder on Amazon, stock up on plant pots at Argos, and buy well-draining soil in bulk from Amazon. Oliver, the founder of Garden List, shares his experiences as a passionate gardener and hopes to inspire a new generation of gardeners. He believes that spending more time outside and enjoying the world can lead to better growth and healthier plants.
Can peonies grow from stem cuttings?
To successfully take peony cuttings, follow these steps:
- Select the right time: late summer or early fall is the best time to take cuttings.
- Prepare your tools: sharp pruning shears, a clean knife, and rooting hormone powder.
- Choose the correct stem: Look for a healthy 6 inch long stem with at least 2-3 nodes and cut it at a 45-degree angle.
- Remove all leaves except for the top two or three.
- Apply rooting hormone: Dip the cut end of the stem into the rooting hormone powder to stimulate new root growth.
- Plant the cutting in a well-draining soil mix.
- Care for the cutting: Keep it in a warm and humid environment.

Can you replant peony stems?
Transplanting peonies involves trimming the stems of herbaceous and ITOH plants before the ground freezes for winter. Herbaceous peonies can be trimmed to the ground before winter freezes, while intersectional peonies should be trimmed to the ground or to the point where the green stems become woody. Woody peonies should never be trimmed or the stems cut, and leaves can be removed from the main stem. Peonies typically need to be transplanted about once every 10 years, but this process may affect the plant’s bloom time.
The first year may not produce a bloom, and if it does, it will be smaller. As the plant matures and the root system grows, mature full-size flowers will be produced. Gently dig around the plant using a shovel to avoid hitting roots.
Can you propagate Itoh peonies?
Itoh or intersectional peonies can be propagated through division, a form of asexual reproduction that yields a duplicate of the mother plant. This method is common for plants like hosta, iris, and daylilies. Planting seeds from a favorite peony variety is exual reproduction, yielding new plants that may not share the same attributes as the mother plant. The process is typically done between late August and early November, and the end result is beautiful, beautiful peonies to spread around the garden or share with friends.
Does cutting peonies encourage growth?
Deadheading is a crucial part of plant care, involving the removal of faded or old flowers from plants. While some species may encourage more flower production, peonies only produce buds once per season. Deadheading prevents seed set, allowing plants to focus on their root system and the next year’s flower crop. It also maintains a neat appearance in garden beds. To deadhead peonies, simply snip back each stem to the nearest set of healthy leaves with sharp, clean pruners.
