Peonies are the ideal plants for Grow-Through Supports. Early in the spring, install them so that stems can develop through the grid.
First-year blooming peonies are uncommon. Three years are frequently needed before you see a profusion of blossoms. However, as the plants begin to bloom, you may anticipate a lifetime of lovely flowers. Rarely do peony plants need to be divided. Fall is the best season for separating clumps if they grow too big for a place or if you want to share the plant with a friend. Trim the plant’s foliage, then carefully dig it up from the ground. Cut portion of the plant into pieces with a sharp knife, being careful to leave behind ample clumps of roots with at least three to five eyes per clump. Replant the original plant in its original location, being careful not to damage any of the very brittle roots or leave any significant air spaces in the planting hole. Water until you are certain that the earth around the roots has settled and the moisture has reached the bottom of the hole. Plants divided in the fall may not bloom the next spring, but they will resume their typical behavior the following year.
All that a peony needs for health is an annual dose of organic all-purpose fertilizer and a top-dressing of compost. If you mulch your flower beds, make cautious not to get mulch on the peonies’ bases. Mulch causes the plant to act as though it has been planted too deeply and will result in few, if any, blossoms.

There are several peony types available today, ranging from time-honored ancestral favorites to novel hues (peach, coral, and yellow), intriguing flower shapes (spiders, singles, and semi-doubles), and various heights and blooming periods. Tree peonies, which bloom earlier than herbaceous peonies, have larger flowers, and may grow up to 6 feet tall, might also be something you want to try cultivating.
A special reminder for gardeners in hotter climates: If peonies receive some shade during the hottest portion of the day, the plants will be more resilient and their blooms will stay longer. In warm climates, peonies are questionable and maybe difficult to grow. Consult a reputable local gardener or your nearest garden center to learn if they may be grown in your area.
The ideal types for luring pollinators have just one or two rows of petals.
When should I buy peonies with bare roots?
Because of its stunning spring and early summer flowers and appealing leaves all year long, peonies are well-liked perennials. For herbaceous peony (USDA Zones 38), which totally wither to the ground in the winter, follow these recommendations. Tree peonies, which resemble shrubs and have woody stems that are always visible (Zones 49), have slightly different needs.
Herbaceous peonies should be planted in the fall, when they are dormant. Peonies that are planted in the spring may not bloom for a number of years, and if they sprout new shoots before setting down strong roots, they may even perish. In the fall, mail-order and neighborhood nurseries offer bare-root divisions. A part of the rooted crown with multiple dark red growth buds known as eyes makes up a bare-root peony division. Every bud in the spring sprouts a stem. Look for a division with at least 3 to 5 eyes because the more eyes a division has, the fuller it will appear.
Fall is the best time to plant bare-root herbaceous peonies.
1. Select a location with well-drained soil that is far from competing tree and shrub roots. Give each plant a three-foot-diameter area to grow in. Because peony stems are prone to breaking when heavy with buds and blooms, avoid windy regions or provide a windbreak. In most places, a setting with direct sunlight is ideal. If your springs are often warm and dry, pick a location with afternoon shade.
2. Make the soil ready. Peonies bloom most profusely when allowed to grow undisturbed in the same spot for many years, therefore it’s crucial to put them in well-prepared, enriched soil. Make a planting hole that is 18 inches deep and 2 feet wide. Compost or well-rotted manure should be incorporated into the hole’s bottom with multiple shovels. Add dirt, additional compost, and a cup of bonemeal to the hole halfway. Also incorporate roughly a cup of ground limestone if your soil is acidic. pH levels of 6 to 7 are ideal for peonies.
3. Place the peonies. Setting the division too deep prevents blossoming; only 1.5 to 2 inches of soil should cover the eyes. Position the eyes so they will be just.5 to 1 inch below the soil surface if you garden in an area with a mild winter. This will expose the roots to as much winter cold as feasible. After setting the peony in the hole, firmly yet carefully pack soil over the roots. Verify that there are no air gaps that can permit the plant to root too deeply.
4. Use a hose to water the plant with a soft stream. After that, surround it with a light mulch, like chopped leaves or evergreen branches, to help control soil temperature and moisture and lessen weed competition. In order for the plant to fully cool, mulch should be removed in the winter. The first year the peony may not bloom, but by the third year it should be in peak condition.
How long do bare root peonies take to grow?
What’s required for peony plants to prosper? These perennials require little maintenance.
- They can survive a lifetime and thrive in USDA zones 2 to 8.
- A must-have is well-drained soil.
- A full day of sunshine is ideal, but a half-day is also acceptable. A prolonged bloom season may benefit from some shade.
- The best time to grow peonies is in the fall, when you can plant them bare root.
- Just an inch or two of earth is placed over the eyes before roots are planted (buds).
- Peonies in pots can be moved in the spring or fall.
- Early in the spring, fertilize.
- After bloom, deadhead the wasted blooms.
In the first two years following planting, peonies develop a strong root system. The first year, they frequently bloom. The size of the plant and blossom both increase the next year. They mature and start to produce a profusion of flowers by their third spring. You may never need to divide your peonies because you can frequently enjoy your peony plants in the same location for decades (unless you want additional plants to grow or share).
In the fall, plant peonies from bare roots. When planted between late August and early November, they will grow more feeder roots more quickly. We have planted in various months of the year (bare root or from pots). I’ve tried planting some in December and January, but they won’t develop much root growth in the first few months. Instead, they will lay in the ground, waiting for the ideal moment to grow. If the chance presents itself, I take chances when planting. I don’t believe I’ve lost any plants because of the time of year I planted them; perhaps slower root development the first year. Sometimes planting a root during the “wrong time of year” is preferable to caring for it in a container. In my experience, peony plants with adequate roots grow and enlarge in the third year, regardless of when they were planted.
Peony plants in pots (containers) can be moved in the spring or the fall. Additionally, bare root peonies can be potted up in the fall or early winter and planted in the spring. Store potted peonies slightly moist in a garage or shed when temperatures fall below 10 degrees Fahrenheit for extended periods of time to protect them from severe freezing/thawing/freezing.
- Peonies adore the sun, and for the optimum growth and bloom, they need at least a half day of it (full sun is ideal). A little bit of shadow is acceptable and can help your peonies bloom with more vibrant color; just make sure they get at least a half day of direct sunlight. (Too much shade will result in little to no peony flower and foliage).
- The optimum place for peony plants to flourish is in the ground, although some gardeners are growing one or two in sizable patio pots. For optimal results, use a large container of 10 gallons or more due to the peony’s relatively massive roots. Make sure it has good drainage, and don’t forget to water it more frequently than a peony that was planted in the ground. Large raised beds are also a good choice for peonies.
- Peonies can grow in a variety of soil conditions and prefer well-drained clay soil. Although you can improve your soil, it is frequently unnecessary. Our farm’s clay soil is well-drained and supports the growth of our peonies. You can adjust your soil if you’d like to increase the organic matter and nutrients.
- Dig a hole that is roughly 15 by 15 inches for the planting site, then fill it with the spaded soil. In order for the root to sit just below or at ground level, only the necessary amount of dirt should be removed.
- With the “eyes” (buds) facing upward, place the peony root at any angle and downward. One to two inches of soil are deposited on top of the “eyes” of the roots, which are positioned close to the surface of the ground (buds). Be careful not to bury peony roots too far. Imagine doing this by placing your bare-root peony “just below ground level” or at ground level with just a few inches of soil mounding over the root.
- Gardeners claim success with planting the peony root near ground level with just a touch of soil (about one half inch) over the eyes in warmer climates (The South, California), where peonies can be grown.
- Itoh Intersectional peonies have very enormous roots, and some of their “eyes” are located on a woody stem. To completely enclose the eyes, you might position these peony roots at an angle. Compared to other herbaceous peonies, itoh peonies can be planted a little bit deeper.
- Immediately after planting your peony root, water it. Make sure to keep giving fresh peony plants water every week or so until the Fall rains take over.
- Check the peony root carefully; if it has sunk too far, pick it up and add more dirt beneath it. For optimal results, make sure the soil is only one to two inches deep. Peonies that are planted too deeply may only produce foliage and no flowers.
- When you plant bare root peonies in the fall, they will develop new feeder roots. The roots buried in the ground won’t be harmed by the winter’s frigid temperatures (garden). Peonies enjoy chilly winters.
- A very large container with good drainage is necessary when planting peony in pots or containers. Make sure that the soil is only one to two inches thick around the eyes. Water the potted peonies and keep them moist, but allow a period of near-dryness between waterings. Protect potted peony from freezing temperatures in the winter. Roots of planted or potted peony plants are not harmed by frost; however, potted peonies may be affected by persistent arctic blasts or deep freezing.
- When you first plant or transplant your new peony plants, give them plenty of water. Deeply water a peony, then wait a few days before watering it again. During dry conditions, watering first-year peony roots/plants every two weeks should be sufficient. The roots’ establishment will be aided by the wetness.
- You might not need to water your peony again until you experience dry weather in the spring or summer until the autumn and winter rains start.
- Peony plants are quite drought tolerant after they are a few years old, though they do benefit from a good watering every few weeks during the hot summers. Peonies do not require frequent watering after they are established.
- Early in the spring, we apply 1/4 cup of fertilizer (10-20-20) to the drip line of our mature peonies. Following blooming, you can fertilize your peony plants. While some gardeners fertilize their peonies yearly, many do not. For the best outcomes with your soil, you might wish to experiment.
- Use a slow release fertilizer when fertilizing potted peonies because other fertilizers will burn the leaves. In the early spring, right before plants bloom, we fertilize.
- After flowering, remove flower/seed pods. You can cut the stems of your peonies to any shape you like.
- Leave seed pods on the stems until they burst open in the late summer if you wish to allow them to mature. The seed can be sown right away in the ground or on potting flats and kept moist until the arrival of the fall rains. Some seeds will grow the following spring, while others will do so the following year.
- In the late fall, trim peony stems all the way to the ground. To keep the garden clean, remove the stems and leaves. Peony stems and leaves should not be composted.
- Northwest regions don’t need to be mulched. Mulch is sometimes used by gardeners in regions with particularly harsh winters; however, if you do this, make sure to remove the mulch in the spring; otherwise, your peony will be “planted” too deeply.
Check for the following signs if your peony start to lose their vitality over time:
- The root may have been buried too deeply as a result of seasonal additions of mulch or bark dust (without springtime clearance). In our northwest environment, peonies don’t require protection because they enjoy the chilly winters.
- Trees and plants in the landscape may offer an abundance of shade.
- It’s possible that tree roots grew through the peony roots, crowding them.
- too much nitrogen
- They might also have lost their vigor, like some individuals, and require reviving. By digging up, dividing, and replanting a division with three to five eyes in a different location that gets good sun and drainage, you can revitalize your peony. They’ll recover quickly.
