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.
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.)
How can peony stems be strengthened?
A. In your article about peonies published in the Flint Journal, you claim that it is best to leave them alone if there are no issues. For roughly 25 to 30 years, I have had two peony bushes in my yard. The stems appear to be weak, which is the sole issue, and when the blooms are in bloom, they topple to the ground. Should I divide them and dig them up?
A. Your peonies are probably content if they are flowering well. The weight of the blossom is probably what caused them to fall to the ground in bloom. The stems’ weakness could be attributed to a nutrient deficit, but in my opinion, the flower’s sheet weight is a far more likely culprit. The large, stunning blossoms can be kept off the ground by doing one of three things.
One method is to encircle the entire plant when it is only six inches tall using bamboo pegs and a “girdle” made of long plant ties (similar to the ones seen on bread packaging that you use to screw them closed, but longer). These can be purchased in rolls of one continuous piece. In any case, you will have space for three tie rings if you use stakes that are, say, four feet high out of the ground. By doing so, the plant will remain inside the “girdle” and the blossoms won’t topple over.
Another thing to do is to de-bud flower-bearing stems. To ensure that a single, big blossom emerges, side buds must be removed. It is advisable to do this as soon as you notice buds on the stems. Simply pinch off the side buds to leave one robust core one. The single bud will receive all of the plant’s energy, and the flower will be fairly enormous. Instead of just rearranging the weight on the stem, you’ll presumably reduce it altogether.
The final option is to cut the flowers and take them inside to enjoy. Peonies make lovely cut flowers, and if you give them new water every day, they should stay beautiful for about a week.
If you decide to go the support route, it’s crucial to set up the support system before the plant grows too big. Once the plant is much taller than 10 inches, it is growing really quickly and is difficult to manage.

How can weeds be kept out of peonies?
Although some variants, including the “Blaze” and “Sea Shell” cultivars, can also thrive in mild temperature locations, the majority of peony varieties only grow in regions with cold winters. Spring garden beds are colored by the enormous, elaborate peony flowers, but grassy weeds can choke out the plants and lessen their beauty. The grass is not only unsightly, but it also deprives the peony bushes of moisture and nutrients. To ensure beautiful and healthy plants, remove the grass from the bed without harming the peony.
Between the grassy area and the peony bed, install vinyl landscaping edging. Create a trench along the edge of the bed, then insert the edging such that 2 inches of it protrudes above the soil and 4 inches are buried beneath it. To secure the edging, fill the trench. A barrier created by the edging helps to stop grass from encroaching on the peony bed.
Early in the spring, before the peony start to sprout, remove all grass and weeds from the bed. To remove the grass’s roots with the least amount of damage, grab the grass close to its base and pull straight up. Grass clumps shouldn’t be dug up since you risk damaging the peony roots.
After the first shoots grow, apply a 2- to 3-inch layer of organic mulch, such as bark nuggets, over the peony bed. Mulch prevents the growth of grass and weeds while also retaining moisture and cooling the soil near the peony roots.
Before the plants grow to a height of 6 inches, cover each peony plant with a wire peony support. The support maintains the floppy peony stems erect, improving the plant’s appearance and making it simpler to find and remove undesirable grass before it can take root.
Check the flowerbed once or twice a week for grass and weeds at the peonies’ bases. Remove any new grass shoots right away so they don’t have a chance to grow and entangle the roots and foliage of the peonies.
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.
