Peonies are a low-maintenance flower, but they still need some TLC to thrive. Plant them in the fall, about 6-8 weeks before the ground freezes, to give them time to establish themselves.
Choose a location with full sun to partial shade and well-draining soil that's rich in organic matter. Peonies can tolerate some drought, but consistent moisture promotes healthy growth.
Peonies have a deep root system, so avoid planting them too deeply. Plant the crown (where the roots and stems meet) about 1-2 inches below the soil surface.

Planting and Care
Planting peonies is a bit of an art, but don't worry, I've got you covered. First, choose a spot that gets at least 6 hours of full sun, as peonies will not bloom in the shade. Peonies need well-draining, neutral soil away from competing tree roots.
When planting, make sure not to disturb the rootball or damage the feeder roots. Planting depth is critical, so cover the peony no deeper than it grew in the pot. Give each peony plant enough space to grow to maturity without being crowded, about 3 to 4 feet in diameter.
Here's a quick rundown of peony care: Water peonies with 1 to 2 inches of water weekly.Feed peonies with a mix of compost and a small amount of fertilizer once a year, right after blooming.Peonies require a chilling period of around six weeks of temperatures below 40°F in the winter to set spring buds.

Planting and Transplanting
Planting peonies in the fall is ideal, about six weeks before the ground freezes, allowing the plant time to settle in and establish roots before winter. This is especially true when planting bare-root peonies or transplanting.
To choose a location for your new peony, select a spot that receives at least six hours of full sun. Peonies will not bloom in the shade, so make sure to provide them with plenty of sunlight.
When planting a container-grown peony, cover it no deeper than it grew in the pot to ensure it blooms properly. Planting depth is critical, and planting too deeply can prevent the peony from blooming.
To transplant a peony, dig carefully around the plant, avoiding damage to the root system. Gently remove the peony from its current location and select a well-draining location with sunlight or partial shade.
Here's a step-by-step guide to transplanting a peony:
- Dig a hole 12 to 18 inches deep and 18 inches wide, spacing the holes 3 to 4 feet apart.
- Add 10-10-10 fertilizer to the hole according to the package's instructions.
- Fill the hole about half full of amended soil.
- Place the root division with the eyes facing upward in the hole.
- Backfill the hole, making sure the eyes are not more than 2 inches below the soil surface.
- Water well.
Peonies can thrive in the same spot for decades, but moving one hastily can bring about its demise. Fall is the best time to move a peony, and it's essential to handle the roots with care to avoid damaging them.
Light

To ensure your peonies thrive, they need at least six hours of full sunlight to produce an abundance of large, healthy flowers. This is crucial for their overall health and blooming potential.
In my experience, peonies that receive less sunlight tend to have smaller, less vibrant flowers. So, make sure to choose a spot that gets plenty of direct sunlight.
The more sunlight your peonies get, the better they'll be able to photosynthesize and grow strong and healthy. This is especially important during the growing season.

Fertilize
Fertilize your peonies lightly. An annual application of compost mixed with a small amount of fertilizer around the base of the plant is all that is needed.
Experts recommend a 5-10-10 or 10-20-20 low nitrogen fertilizer to encourage strong roots and exquisite blooms. Liquid fertilizers are best for peonies as they don't like their roots disturbed.
To avoid fertilizer burn and crown rot, mix a slow-release fertilizer into the soil 6 to 18 inches around the crown of the plant. Don't spray fertilizer on or too close to the crown.

If soil has eroded from around your peonies, you can add organic material like homemade compost or composted cow manure around the base of the plant. Just make sure not to pile it too deep.
Here's a summary of the best fertilizing practices for peonies:
Garden Maintenance
Deadheading peonies after they finish flowering is a must, as it keeps the plant looking tidy and encourages new blooms. Cut the stem underneath the old bloom, leaving the foliage alone, to prevent the petals from browning.
To maintain good air circulation and prevent fungal diseases, prune any dead or diseased stems as soon as you notice them. This will also help prevent the spread of pests like botrytis.
Peonies can be prone to powdery mildew in late summer, but don't worry - it's not a major issue. Simply improve air circulation around the plant to prevent it from becoming a problem.
In the fall, it's also a good time to move your peonies or take cuttings for propagation. Dig up the roots, leave them untouched for a couple of days, and then cut them to make it easier to transplant or share with friends.
Pruning
Pruning is an essential part of peony care, and it's best done at the right time to promote healthy growth and blooming. Prune dead stems and branches after the blooming period, cutting back to right above the first bud.
To maintain plant health, inspect your peonies during pruning and remove any dead or damaged stems. This will prevent the spread of disease and encourage new growth.
Pruning peonies in late fall or early spring is also recommended, cutting them back to ground level before new growth emerges. This will help the plant conserve energy and promote healthy growth in the spring.
Here's a quick guide to pruning peonies:
By pruning your peonies at the right time, you'll be able to enjoy their beautiful blooms for years to come.
Add Supports
Adding supports to your peonies is a great way to prevent them from flopping over. It's much easier to add supports early in the spring when the plants are still small.
You can use stakes or cages to prop up your peonies, especially if they're prone to falling over due to heavy flowers or brittle stems. Peony rings or tomato cages work well for this purpose.
Adding structure early in the spring means your peonies can simply grow through the supports. This way, you can just leave them until fall when it's time for pruning.
It's best to place supports around the peony sprouts in early spring, rather than waiting until they're already big and falling over. This will prevent accidental damage to the crown.
Many newer hybrids are being developed with stronger stems, so you may not need to stake them at all. However, it's still a good idea to provide support for your peonies to ensure they grow upright and healthy.

Peonies need at least six hours of full sun and good air circulation to prevent powdery mildew. Too much shade or crowded plants can lead to this issue.
Removing affected parts of the plant and improving drainage can help prevent phytophthora blight, which is caused by poor drainage. Overwatering can also exacerbate this problem.
Copper soap fungicides can help combat gray mold (botrytis), and using them in conjunction with good air circulation between plants can make a big difference.

Optimizing Growth
To optimize growth, give peonies at least six hours of sunlight daily. This is crucial for blooming, as lack of sunshine can stunt their growth.
Plant peonies no more than 2 inches deep to ensure the roots have enough space to breathe. This simple step can make a big difference in their overall health.
Deadhead peonies after the blooms have faded to encourage more blooms. This will also help prevent the plant from using energy to produce seeds instead of new growth.
Getting to Bloom

Feed your peonies lightly with a mix of compost and a small amount of fertilizer around the base of the plant, just after they've finished blooming.
To encourage strong roots and exquisite blooms, use a 5-10-10 or 10-20-20 low nitrogen fertilizer. Liquid fertilizers are best for peonies as they don't like their roots disturbed.
For extra-large blooms, disbud your peonies by pinching off the small side buds in spring, leaving the terminal bud to grow into a bigger and more magnificent bloom.
Give peonies at least six hours of sunlight daily to promote blooming. Lack of sunshine, smothering the roots and eyes, and too much nitrogen can stunt blooming.
Peonies need a solid winter freeze to store energy in their roots to form the buds for the following spring. This means they're not a good prospect for warm zones like Southern California, Florida, and some southern states.
Don't smother peonies with mulch in winter, but you can mulch loosely with pine needles or shredded bark in the first winter season. Remove the mulch promptly in spring to prevent harming the plant.

Propagating
Propagating is a crucial step in optimizing growth for many plants, including peonies. Peonies are best propagated by lifting and dividing the root clump.
It's essential to do this after about 10 years when the plant starts to lose its vigor and becomes root-bound. Fall is the best time for this activity.
To propagate peonies, you'll need a hose and a sharp knife. Cutting the foliage back down to ground level just before dividing will help make the process easier.
Dig up the entire plant and soak it with a hose to remove as much soil as possible. This will make it easier to manipulate the roots.
Using your hands, separate the roots into dividable portions, each with three to five "eyes" – small reddish buds that resemble potato eyes. Then, use a sharp knife to cut the tuberous root clump into divisions.
Here's a quick summary of the steps:
- Divide the peony plant after 10 years when it becomes root-bound.
- Soak the plant with a hose to remove excess soil.
- Separate the roots into portions with 3-5 "eyes" each.
- Cut the root clump into divisions using a sharp knife.
- Replant the divisions as soon as possible.
Common Issues
Peonies are a hardy shrub that requires minimal maintenance once established. They're susceptible to their own set of issues, so it's essential to be aware of the common problems you might encounter.
One issue you may face is a lack of blooms. This could be a sign that your peonies were planted too deep into the soil. Too much soil around the crown of the plant can prevent them from blooming.
Digging up and replanting your peonies can fix this issue, and they should start to bloom in the seasons to come.
Common Problems
Peonies are a hardy shrub that requires minimal maintenance once established. However, they can be susceptible to certain issues.
Peony leaf blotch can cause dark splotches on leaves, especially in hot, humid weather. Cut the peony to ground level in fall or early spring, improve air circulation, and use ground irrigation.
Peonies can live for decades with minimal care when planted in suitable soil. They can be temperamental when moved once established.
Here are some common problems to watch out for:
- Peony leaf blotch: caused by hot, humid weather
- Temperamental behavior when moved: can be challenging to transplant once established
No Blooms
If your peonies aren't blooming, it's worth checking if they were planted too deep into the soil. This can prevent them from blooming altogether.
The ideal soil level for peonies is when the crown of the plant is exposed and not buried under too much soil. Too much soil around the crown can prevent blooming.
You may need to dig up your peonies and replant them to fix this issue, but it's a worthwhile effort.
Seasonal Care
Taking care of peonies requires attention to their specific needs at different times of the year. Here are some key things to keep in mind:
In the spring, add a thin layer of compost around your peony bushes. This will give them a nutrient boost as they grow.
Deadheading peonies after they finish flowering is also important. Cut the stem underneath the old bloom, leaving the foliage alone.
Peonies can be susceptible to powdery mildew in late summer, but good air circulation can prevent this issue.
To promote new growth in the spring, prune your peony bushes in the fall after the first frost. Cut them back to the soil level to encourage healthy growth.
Mulching new plants with evergreen boughs or salt marsh hay after the ground freezes can also help prevent overwintering pests.
