Peonies are frequently shielded from the harsh winter in colder climates by a high mound of mulch. In order to provide peony shoots the much-needed exposure to sunlight, the first step in spring maintenance for peony plants is to remove any mulch or other debris from their immediate vicinity. The area around peony plants is an excellent time to weed as well.
Weeds frequently invade gardens in the spring before beautiful plants do, and peonies struggle to compete with weeds. Herbicides should never be sprayed close to the crowns or root zones of peony plants. First, hand-weed the area. After manual weeding, you can use a pre-emergent herbicide like Preen around peony plants if you need further assistance managing weeds, but only when peony shoots are at least 6 inches (15 cm) high.
Sometimes, soil nutrients are lost due to melting snow and spring showers. To avoid fertilizer burn and crown rot, fertilizer should never be applied on or too close to the crown of peony plants. A low nitrogen, slow release fertilizer should be placed into the soil 6-18 inches (15-46 cm) away from the plant crown for optimal results. It is advised to use a low nitrogen fertilizer, such as 5-10-10 or 10-20-20, to promote robust roots and gorgeous blooms. You can add organic material if the soil surrounding your peony plants has eroded, but avoid using manure because of its high nitrogen content.
Peony growers occasionally remove side buds and leave only terminal buds in order to produce extra-large, show-quality blooms. Preparing peonies for development is another aspect of springtime care. Plant supports are frequently used to hold peony plants upright because they have a tendency to flop over. Place these peony rings or supports in the early spring when the plants are still young.
Additionally, it’s a good idea to keep young children and pets away from the springtime delicate young shoots of peony bushes. Young shoots are readily broken, which makes them vulnerable to pests, illnesses, and even plant death.
Botrytis is a fungus-related disease that can affect peonies. At the root of plants or in garden detritus, fungi can overwinter and produce new spores. Fungus spreads and thrives in the spring when the temperature and humidity rise. When caring for peonies in the spring, you should use copper fungicide or lime sulfur on the plant.
Mulch would peonies grow through it?
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.
How is the mulch treated for peonies?
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.
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.)
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!
