Peonies are among the most beloved flowers in the garden, prized for their lush, full blooms and delightful fragrance. Getting these perennial plants established correctly is important for their health and performance. Knowing when to plant peony roots is one of the keys to success with these flowering shrubs.

Why Fall is the Best Time to Plant Peonies

The optimal time for planting peony roots is in early fall, around September or October depending on your climate. Planting in fall allows the plants to establish roots before top growth begins in spring. When you plant peonies in fall, the energy can go toward root development rather than foliage production This leads to faster establishment and better blooming in subsequent years.

Spring planting is possible but not ideal. When planting in spring, the emerging foliage competes for resources with the developing root system. This can stress the plant. Summer planting of potted peonies is not recommended because of heat and water stress.

For best results, plant peony roots in the fall about 6-8 weeks before the ground freezes. This gives them enough time to anchor before going dormant for winter.

How to Determine the Fall Planting Window

The ideal fall planting window for peonies varies by growing zone. Here are some guidelines:

  • Northern zones 2-4: Plant in September
  • Mid zones 5-6: Plant in October
  • Southern zones 7-8: Plant in November

To dial in the timing watch the weather forecasts for your first expected fall frost date. Then back up 4-6 weeks from the frost date to find your ideal planting window. Reputable peony root suppliers ship orders to arrive within this window. If you miss the window store roots in a paper bag in the refrigerator until planting.

Spring Planting Peonies

While fall is best for planting peonies, you can still plant in spring with proper care The ideal spring planting time is after the threat of hard frost has passed Wait until daytime temperatures are consistently 50 degrees Fahrenheit or above before planting.

With spring planting, take extra care to keep plants well watered, especially during the first summer. Apply mulch around the plants to retain moisture. Be patient, as spring-planted peonies may not bloom well the first year as the plant focuses energy on establishing roots. But with proper care, they will catch up and flourish.

How to Prepare Soil for Peonies

Peonies thrive in fertile, well-drained soil. When planting peonies, work plenty of compost into the soil to improve drainage and nutrients. The planting bed should be prepared to a depth of 12-18 inches to accommodate the deep peony roots.

If your native soil is dense clay, amend it with compost to improve aeration and drainage. Mix in some garden lime if the soil pH is too low. Peonies prefer a neutral to slightly alkaline soil pH around 6.5-7.5.

Planting Depth for Peony Roots

Proper planting depth is crucial for peonies to bloom well. Plant the root system so the pinkish buds or “eyes” are 1-2 inches below the soil surface. Resist planting too deeply, which can prevent flowering.

Find the section of the root with visible leaf buds. Position this at soil level, with buds facing upward. Then backfill the hole with soil to cover the buds by 1-2 inches. The thicker, deeper section of the root can angle downward.

Caring for Peonies After Planting

After planting peony roots in fall or spring, care for them as follows:

  • Water thoroughly after planting and weekly the first year. Give plants 1-2 inches of water per week.

  • Apply 2-3 inches of organic mulch around plants to conserve moisture and reduce weeds. Replenish as needed.

  • Fertilize in early spring with a balanced fertilizer or compost tea. Discontinue feeding after flower buds form.

  • Stake tall, floppy stems in early spring to prevent damage.

  • Remove spent flowers to encourage reblooming. Deadhead regularly during bloom season.

  • Let foliage die back naturally after flowering. Do not cut back leaves until they yellow in fall.

  • Divide congested clumps every 3-5 years in fall after foliage dies back. Replant divisions promptly.

When to Expect First Blooms from New Plants

Be patient with newly planted peony roots, as it takes some time to establish blooming size plants. Here are some blooming expectations:

  • Fall planted peonies often bloom lightly the following spring. Expect just a few flowers the first season.

  • Spring planted peonies may not bloom until the second season after planting. Focus energies on root growth.

  • By the third year after planting, peonies hit their stride and put on a full floral display.

  • Mature peony plants can produce 50 or more blooms per plant at peak size!

Tips for Buying Peony Roots

When shopping for peonies, look for plump, firm roots with visible pinkish leaf buds. Avoid shriveled or moldy roots. The best selection is available in late summer and fall. Potted peonies are often smaller divisions.

Choose bare root peonies over pots for the best value. Bare roots are economical and establish more readily than container plants. Mail order suppliers offer the widest variety of peony cultivars.

Select varieties that bloom at different times to extend the season. Mix early, mid and late bloomers. Also choose a variety of flower types, colors and fragrances for interest.

With proper planting and care, peonies will flourish for decades in the garden. Follow these tips on when to plant peony roots, and you’ll be rewarded with magnificent blooms year after year.

Planting Peonies in Spring

Planting peonies in spring can be a successful endeavor, especially for gardeners who missed the fall planting window.

Here are detailed steps and considerations for spring planting:

Peony Cultivation and Care

  • Soil Requirements: All types of peonies prefer well-drained soil with a neutral to slightly acidic pH.
  • Sunlight: Full sun is ideal for most peonies, though partial shade is tolerated, especially by tree and Itoh varieties.
  • Watering: Regular watering is important, especially during the dry periods of summer. However, its crucial to avoid waterlogging the soil.

Each type of peony offers something special to the garden, from the towering elegance of tree peonies to the classic beauty of herbaceous peonies and the unique characteristics of Itoh hybrids.

Selecting the right type depends on your garden space, climate, and personal preference for flower type and color. With proper care and placement, peonies can be a long-lasting and stunning addition to any landscape.

Proper care is essential to ensure your peonies thrive and produce stunning blooms year after year.

Heres a detailed look at how to care for your peony plants:

  • Consistency: Peonies require consistent moisture, especially during their growing and blooming season in spring and summer. However, they do not tolerate waterlogged soil.
  • Method: Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. Using a soaker hose or drip irrigation can be beneficial.
  • Frequency: Adjust watering based on rainfall; during dry spells, peonies may need weekly watering.
  • Soil Quality: Peonies flourish in well-drained, fertile soil. If your soil is heavy or clayey, consider amending it with compost or well-rotted manure.
  • Fertilizer: Apply a low-nitrogen fertilizer or balanced 10-10-10 fertilizer in the spring as new growth appears. Avoid over-fertilizing, as this can lead to more foliage and fewer blooms. Here is the fertilizer I recommend:
  • Sun Exposure: Plant peonies in a location where they receive at least six hours of full sun per day. While some varieties tolerate partial shade, too little sun can result in weak stems and fewer flowers.
  • Herbaceous Peonies: After blooming, deadhead spent flowers to maintain plant appearance. In fall, cut back the foliage to ground level after it has died back.
  • Tree Peonies: Pruning is not typically necessary, except to remove dead wood or shape the plant. This should be done after flowering, in late spring or early summer.
  • Itoh Peonies: Treat these like herbaceous peonies, cutting back to the ground in autumn.
