Peonies, including herbaceous and tree peonies, benefit from being cut back in autumn for health and shape. Tree peonies should not be cut back to the ground yearly but can be pruned after blooming is finished. Peonies need to be cut back just once a year, with stems clipped as close down to the ground. Gardening expert Melissa Strauss has the lowdown on pruning, stating that it will keep cut peonies fresh for longer.

Peonies come at a time when there are few other flowers blooming in the garden, and by mastering the art of pruning in the fall, you can prevent common issues and promote robust growth for the next spring. After the flowers fade, the plant will redirect its resources to the tubers, which act as storage tanks. When the tubers are well developed and thick in the fall, you can divide your peonies.

Fall care of a peony bush all starts with cutting it back, whether you plan on digging up and dividing your peony bushes this fall or not. Your peony is an herbaceous perennial that dies back every year and then grows new stems from the roots each spring. You can either cut back the foliage to the ground in late fall/early winter or wait until early spring to remove.

Peonies do not bloom after being cut, and if cut too early the next year’s bloom may be affected. The best time to prune a tree peony is right after it blooms, but do not cut it back in the fall as you would an herbaceous or Itoh peony.

Tree peonies can trim off the dead peony blooms but leave the foliage intact. The plant needs all of its leaves to build up the blooms for next year, so be sure to wait until the right time to cut.

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”.

Peonies can bloom for over 100 years, with each individual bloom lasting 7-10 days. To extend their blooming season, plant varieties that flower at different times within a 6-week period. These types are labeled as early, early-mid, mid, and late season. Early-season Peonies, which are the first to bloom, offer a variety of colors, forms, and fragrances. They are ideal for mild winter climates or areas with early summer heat, as they bloom before intense heat allows the plants to fully flower.

Early mid-season Peonies, which arrive between the first and mid-season Peonies, offer a wide variety of vibrant colors, fascinating flower forms, and incredible fragrance. By planting these varieties, you can extend the blooming season of Peonies and enjoy their unique beauty and fragrance.

Does cutting peony flowers hurt the plant?

In the first year, avoid cutting flowers and remove all buds, except for one. This may prevent the plant from attempting to bloom this year. In the second year, leave the plant to itself, allowing any blooming flowers to remain. Remove spent flowers as soon as they fade and leave all leaves. If the plant is doing well, cut a few stems but leave as many leaves as possible to store energy for next year’s blooms. In the fourth year and beyond, if the plant is happy, cut more flowers and leave more leaves.

To extend the bloom season of peonies, follow these tips:

Plant peonies in a rotation scheme that includes varying varieties, exposure, and age. Older plants typically bloom faster and earlier than newer ones. Dividing the parent plant also adds a little difference in bloom times.
Vary exposure with different plantings to adjust the bloom schedule. Full 8 hour sun exposure vs a bit of shade in the morning or afternoon can shift the plant to a later bloom cycle. Using a combo of all three will give great results.
Refrigerate your cuttings. Blooms that spend time right away in the fridge last much longer. Using damp paper or wrapping them in plastic can provide weeks of storage, even months for some varieties. When removing the cuttings, cut the stems and put them in lukewarm water to initiate the bloom.

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.

Do peonies regenerate?

Peonies require around six weeks of cold weather to induce dormancy and bloom in the spring. To protect them from the dropping temperatures, prune them to the ground after the bloom period, keeping the foliage and branches. Mulching the roots of younger plants can also help. Common pests and plant diseases include Botrytis, a fungal rot that infects leaves and stems, causing black or grey mold growth.

Remove infected areas to prevent spread. If a leaf is wilting or blackening, remove it. Powdery mildew, another fungus, leaves a white residue that can be treated by gently washing them with water or a fungal spray.

Will peonies grow back if you cut them?

Peonies are the most anticipated blooms in spring, with their vibrant colors and personality bringing joy to the garden. It’s important to know when to cut back peonies to ensure they reappear next spring. Peony season, which can range from April to June, can be short, but shopping at the garden center can provide information on early-, mid-, and late-season bloom times. Staggered peonies allow for longer enjoyment of the flowers.

When to deadhead peonies, it’s essential to enjoy the flowers before a spring storm or heavy rainfall. If peonies flop due to weight or heavy rainfall, consider placing a peony hoop over the plant early in the spring. Deadheading faded flowers once they’re past their prime doesn’t encourage more flowers like on other annuals and perennials.

In summary, knowing when to cut back peonies is crucial for ensuring their beauty and longevity in the spring garden. Deadheading faded flowers can help maintain the beauty of the plant and encourage more flowers.

How do you force cut peonies to open?

To facilitate the opening of flowers, it is recommended to make a fresh diagonal cut and place them in warm water with a minimal quantity. This method is a standard practice among florists to ensure optimal flower opening.
