The finest mulches to use with peony plants are those that are organic, such as straw, pine needles, shredded bark, and peat moss. Organic compounds break down into the soil every one to two years and aid in moisture retention and weed control. Nutrients are not added by stone mulch. Even though they are organic, they only really benefit your peony by warming the soil around the roots.
Is mulching permitted around peonies?
“The peony has adapted to a variety of conditions throughout the northern hemisphere, making it arguably the perfect plant for Canadian gardens. They are as sturdy as paving stones, as resilient as ordinary marigolds, and as tough as a Scotch thistle, according to Jack Kelway, one of the most well-known peony gardeners in England.”
In zones 3 through 8, peonies can survive. Once planted, they take little maintenance and are simple to grow. Peonies frequently live for more than 50 years when given the correct conditions.
Keep your new peony root cold and shaded until you’re ready to plant it after you receive it in the fall. While it’s ideal to plant it as soon as possible, your roots will be alright if left in the aforementioned circumstances for a week or two. To check for condensation-related moisture, open the box and bag. If you have any peat moss, add a bit to the bag.
In Southern Ontario, we planted far into November, but to prevent the ground from freezing, we covered it with leaf mulch.
The Canadian Peony Society (www.peaony.ca), which provided a lot of the following information and the planting diagrams, is to be thanked.
- Peonies should be planted in healthy, well-draining soil with at least six hours of direct sunlight each day because they detest having wet feet.
- Sprinklers placed over them should not be used to water them every day.
- Although they can tolerate a wide variety of pHs, they prefer neutral to slightly alkaline soil with large levels of organic matter.
- Peonies planted in sandy soil take less time to establish but may yield less spectacular blossoms, whilst peonies planted in clay soil take longer to establish but produce gorgeous flowers. When growing in sandy soil, first amend with compost and topdress the soil every year to replenish it. If you’re planting in clay, you might want to fill the bottom of the hole with with sand or another material that drains effectively.
- If you decide to move or divide your peony, fall is the best time to do it. Below are planting instructions.
- Three growth seasons are necessary for new plants to mature fully and set a profusion of blossoms. Flowers produced by immature plants frequently differ from those of the mature blooms.
- A consistent top-dressing of organic material every fall will benefit your peony. Avoid applying manure or compost directly to the plant’s crowns; instead, use well-aged manure and/or well-composted material to surround your peony. Moreover, never use new manure. That is intolerable to them!
- If you choose to fertilize (we don’t), you should do so in the early spring when the shoots are about 6 inches above the ground. Fertilizer 5-10-10 is what we advise. The first number must be less than the second and third numbers for this to work. The shoots shouldn’t come into close contact with fertilizer. Around the shoots, dispense the fertilizer at a distance of about 6 inches. Once your peonies are trimmed down for the winter in the fall, you can submit another application.
- Only well-draining soil should be used for peony planting. Don’t put them under a downspout or in a wet hollow since they really don’t like having their feet wet. Once more, for best results, overhead sprinklers should NOT be used to water them every day.
- Make sure that new plants receive a good soaking every two to three weeks over the first two growing seasons. Water your plants in the morning so they have time to dry off before dusk. Peonies shouldn’t need extra watering after their third growing season, unless there is an exceptional drought.
- Three growth seasons are necessary for new plants to mature fully and set a profusion of blossoms.
- When side buds start to emerge on your plants’ stems, remove them if you want flowers fit for a flower show. Remove the wasted flowers from your peony once it has completed flowering so that the plant may focus its energy on developing strong roots rather than seed production. When your plant is fully grown, you could decide to leave part of the gorgeous seed heads that some types produce.
- Wait until the first frost to trim the foliage.
following the initial harsh frost:
- Cut herbaceous peonies just an inch above the surface of the soil.
- Itoh peony should be pruned so that the stalks are only 2 inches above the soil.
- Take the leaves off of your garden bed.
Mulching is recommended for peonies the first winter after planting. The mulch helps avoid frost heave by shielding the roots from damaging freeze-thaw cycles. After the earth has frozen, cover the area where the root is planted with a 3 inch layer of mulch.
Early in the spring, when the ground has thawed and shoots start to sprout, remove or pull back the mulch. Some people advise pulling back the mulch once your tulips bloom. Since the plant responds to both light and heat, it is crucial to remove the mulch as soon as shoots are visible. We use straw as mulch since it is simple to remove off the peony shoots in the spring and we always have it on hand. Also effective are evergreen boughs or leaf mulch. Following the first winter, mulching is not necessary.
Don’t try to force your plant down if you discover in the spring that it has heaved too close to the surface; instead, add more dirt around it.
Peonies are generally free of diseases and pests. Their foliage doesn’t seem to appeal to deer. Rabbits occasionally cause a little bit of damage, but they typically try them and spit them out.
PLANTING INSTRUCTIONS
Roots for peonies should be planted in the autumn. Plant such that the crown of the roots, which contains the eyes (little pinkish buds), is not covered by more than 2 inches (5 cm) of dirt. The shoots for next year are these eyes. Flowers won’t bloom if they are buried too deeply. The eyes will freeze and die back throughout the winter if they are planted too shallowly. Some species have enormous eyes, whereas others have considerably smaller ones.
Make a hole that is 18 inches broad and 18 inches deep. Fill the hole with some composted organic material. 14 cups of 5-10-10 fertilizer are optional. In this case, backfill the hole with some soil to prevent the root from coming into contact with the fertilizer. With the roots pointed downward and the eyes 2 inches below the top of the hole, insert the root into the hole. Cover with soil and thoroughly hydrate.
Planting distances for peonies should be 3 feet. Planting dwarf or border types closer to one another is possible.
Fall is the ideal time to grow peony roots. The appearance of Itoh roots and Herbaceous Peony roots differ slightly. They may have eyes on the stem, crown, or both. When establishing these roots, make sure that all of the crown’s visible eyes are buried 2 to 3 inches (5 to 10 cm) into the soil’s surface. If at all possible, the root should be placed so that the first eye above the crown is at soil level.
Make a hole that is 18 inches broad and 18 inches deep. Fill the hole with some composted organic material. 14 cups of 5-10-10 fertilizer are optional. In this case, backfill the hole with some soil to prevent the root from coming into contact with the fertilizer. As seen above, insert the root into the hole such that the roots point downward and the crown’s visible eyes are all two inches or more above the top of the hole. Cover with soil and thoroughly hydrate.

Peony Cages
You may purchase peony support cages like this one with stackable rings that are built exclusively for blooms like peonies.
A little peony plant can be effectively supported by wire tomato plant supports, such as these robust wire tomato cages or these handy foldable tomato cages.
Homemade DIY Peony Supports
The simplest solution in this situation is to make your own plant hoop supports using heavy-duty stakes, twine, or ties (I enjoy using these stretchy plastic ties or this cut-a-size wire garden twist ties).
Do peony need to be mulched during the winter?
Peonies should be pruned almost to the ground in the fall after the leaves turn yellow. However, take care not to remove any of the reddish or pink buds, also known as “eyes,” as the eyes, which are found close to the ground, are the beginnings of the stems for the following year. (Don’t fret; the eyes won’t become frozen.)
Should peonies have summer mulch applied?
Peonies should, in theory, receive 1 inch of water per week from rain or a watering system. Check the soil to see whether your plants need watering if they haven’t received 1 inch of moisture this week. To achieve steady penetration to a depth of 10 to 12 inches, use a sprinkler or soaker hose. To learn more about the goods, consult the document on Choosing Watering Equipment.
Each spring, give peony a small amount of all-purpose granular fertilizer, especially one that contains slow-releasing nitrogen. Fresh manure should not come in contact with fleshy roots. To increase the drought and disease resistance of peony leaves, some serious gardeners mist the plant’s foliage once or twice during the growth season with a diluted solution of liquid fertilizer or seaweed extract. See the Fertilizers file for more details.
A rising variety of items are available on the market that can make your plants healthier, more drought-resistant, disease-resistant, and even insect-resistant. These products are typically inexpensive and simple to use. Check out New Technology In Plant Growth Activators if you want to give your plants some more vigor.
Mulching prevents dirt from splashing up on the flowers, helps manage weeds, and preserves soil moisture. The soil around the peony plants should be covered with a 1 to 2 inch layer of shredded bark, chopped leaves, wood chips, dried grass clippings, or other beautiful organic materials. Keep in mind, however, that peony eyes should never be buried more than 1 inch into the soil. Additionally, mulch will keep the soil cool during the sweltering summer.

Despite their remarkable hardiness, peonies benefit from a winter mulch, especially during their first winter. When the ground has frozen over completely, cover it with a thick layer of organic material that will allow air and water to pass through, such as evergreen branches, chopped leaves, or straw. This will protect the soil from temperature extremes that could cause it to heave and damage peony plants that were planted in shallow soil. Refer to the document on Using Mulch for further details.
Remove side buds early in their development to encourage larger blossoms on your plant, leaving stem-end buds to receive the most nutrition and develop into enormous size. While in bloom, deadhead (cut off) fading peony blossoms frequently. Additionally, remove any weak or unhealthy-looking stems or leaves.
Peony clumps that are well-established and plants with particularly enormous blossoms may require staking. Set four pegs into the ground around the clump before the buds start to open, taking care not to damage it. Then, thread strong twine or wire back and forth among the tops to create a lattice that will allow blossom-bearing peony stems to grow through and be supported. Use ready-made metal staking rings as an alternative. See the document Staking Flowers for further details.
Peony clumps can be separated to produce more plants, but they don’t need to be disturbed for up to ten or even twenty years. Gently dig up a root clump to separate it. Cut the clump into sections with a sharp knife, leaving at least three “eyes,” or growth points, on each section. Each part should be quickly and properly replanted in a bed that has been prepared.
Can I surround my peonies with rocks?
Regardless of where you are in your peony season, Becky and I spent this afternoon removing the peonies from the area around our house. Hopefully, these pointers will assist you in organizing your peony beds as a home gardener. Do we do this every spring, as some of the images will show you? No, not quite, but we had to do something with the extra time we had and the 70 F temperature today. I shot several examples, which you can see here. A video will be available soon.
Does this seem like it belongs in your gardens? Yes, peonies are not buddies with grass or clover. Peonies will be growing in the grass, and over time, they can start to deteriorate. In a few of our test fields, we do utilize cover crops, but we are ceasing to do so because the development of the peonies is significantly behind that of our other fields that do not.
Does this not appear better now? If you have grass encroaching on your peonies, we advise gently removing as much of the grass roots as possible with a gardening knife or spade so that the peonies can thrive. To ensure that the grass grows continuously during its lifespan, keep it as far from the peony’ drip line as possible.
Landscape rock is a beautiful addition to many of our beds, but they really mess with peony soldiers trying to emerge from the ground. In addition to preventing their growth, rocks typically have plastic under them. As peonies spread out, we ran into the plastic after removing the rock, which prevented any peony soldiers from erecting themselves. Make sure to cut the plastic and tuck it under the plastic far enough away from the peony soldiers after you’ve taken the rock out of the way. Since we hadn’t carried out this activity in around 3 years, we discovered several peony troops beneath the plastic, which will now break the surface.
Now that we are aware of the damage that these peonies caused in this landscape rock bed, we will keep the rocks out of the peony soldiers’ reach. The peonies were undoubtedly joyful once more!
Shredded wood mulch is a perennially popular landscaping material. On a related note, I don’t like Cyprus mulch or any dye-colored mulch. A smart tip is to exercise caution while using any hardwood mulch. Western Red Cedar is my favorite wood mulch since it lasts longer and does not break down and compact like other types. Although it is more expensive, we use it and are pleased with the way our flower gardens look, smell, and function. Returning to the issue with all mulch made of shredded wood, even though it isn’t as harmful as landscape rock, unattended wood mulch can suffocate peony soldiers.
When photographing the “after” photo, the sun just so happened to peek through the clouds. Remove as much of the wood mulch—roughly to the drip line—away from the peonies as you would landscape stones. This will also aid in the dirt around your peony drying off rather than remaining wet. The mulch may occasionally be removed further away if it has been a particularly wet spring or summer so that the ground may dry out more quickly. Given that peony dislike constantly damp growing environments, bare ground and excellent drainage are essential.
Follow Redd’s advise and keep landscaping elements away from peonies to see them flourish!
