Peonies can be identified by their distinctively large, vividly colored blossoms. Peonies can grow in a range of soils, but only soggy, poorly draining soil can result in root rot. This does not imply that peonies are water-free. On the other hand, older plants require frequent additional watering whereas these perennial beauties need to be kept moist the first year. Your region may have different peony water requirements, but knowing when to water them will help your plants thrive.
Western North America, Asia, and Europe are the native home of the peony. They develop from large, divideable store roots that serve as the foundation for new plants. These roots do not penetrate the soil very deeply. Rather, they have dense branching and few surface roots. Due to their unique structure, they are unable to efficiently collect dew and lighter moisture near the surface or moisture from deep under the soil.
After establishment, peonies may survive short periods of drought, but for the best growth and healthiest roots, regular watering is essential. Plants typically require 1 inch (2.5 cm) of water every week.
Can a peony be overwatered?
Let’s go through specifics on how to take care of your peony now that you’ve chosen the ideal location for them to flourish and understand when and how to plant them.
Best Soil For Peonies
Peonies aren’t overly picky, so you don’t need to worry too much about the precise soil type. However, it is ideal to grow them in a rich, fertile, and quick-draining soil. The pH of the soil where they are planted should also be neutral.
Use a soil ph meter or a cheap soil test kit to determine the sort of soil you have if you are unsure.
To make caring for peonies easier, it may be a good idea to amend your soil with compost before planting if it is extremely sandy or hard clay.
Additionally, they can’t stand wet soil for very long, so plant them where the earth can drain pretty quickly.
Tips For Watering Peonies
Another crucial aspect of caring for peony is watering. Never overwater peonies because they detest having wet feet and hate being overwatered.
Additionally, take careful not to put them where the soil will remain moist for an extended amount of time. A useful instrument to use for determining how moist or dry the soil is is a soil moisture gauge.
In order to prevent concerns with mildew and disease, it is better to water your peony from the bottom rather than over the top of the leaves.
Deadheading & Pruning Peonies
Although pruning peony bushes is not strictly necessary, it does help to maintain the plant’s finest appearance, guard against disease and mildew problems, and prolong flowering.
Making trimming a frequent part of your daily peony care routine is therefore an excellent idea. Here are some brief hints on how to prune peonies and when to do so.
Peonies’ flowering period can be prolonged by deadheading them in the spring. There are a few buds on each stalk, and removing the larger center flower once it has begun to fade can encourage the smaller side buds to bloom more consistently.
Simply remove each individual flower from a peony with a clean, sharp pair of pruning shears as soon as they start to fade.
after blooming, peonies are pruned
Pruning down peony stems to below the height of the bush once the plant has finished blooming will prevent the empty stem from protruding throughout the summer.
In order to maintain its shape and increase airflow, you can also thin the entire bush at this time and prune it back a few extra inches.
When pruning peonies in the summer, keep in mind that your plant needs leaves to produce enough energy to blossom again the following year.
Using hand pruners to painstakingly prune each stem is an option. To make the process simpler, you can also use electric hedge trimmers or hedge shears.
Fall pruning of peony
For peony, pruning is a crucial element of fall maintenance. Instead of waiting until spring, you should remove all the leaves and stems in the fall following a fatal frost.
Cutting back peonies in the fall is especially crucial if your plant had a disease or mildew infection since those spores can survive the winter on the leaves and spread the infection to new growth the following year.
Peony Fertilizer Requirements
Peonies don’t require fertilization because they can survive without it, especially if the soil was improved before to planting. But they will undoubtedly profit from it if they were planted in poor-quality soil or if you had never given them food before.
After plants have finished blooming in the early summer, is the best time to feed peonies. Really, all they require is an annual side dressing of compost or aged manure and the use of an organic all-purpose fertilizer.
However, never add compost on top of the main rootball; doing so could cause the plant to act as though it was planted too deeply and cease blossoming.
I generally advise choosing organic fertilizers over synthetic ones when it comes to peony because they function better and provide less of a risk of burning your plants.
My favorite organic fertilizer for peony plants is compost tea (you can get compost tea bags to make your own compost tea or pre-made liquid compost tea concentrate) (you can buy liquid fertilizer, or use slow-release granules if you would rather).
Should peony be watered daily?
After planting, give your peony plants a little drink to help the dirt surrounding the roots settle. The ground normally has adequate moisture for peony plants during the spring, but if several weeks go by without rain, give them a good watering once every two weeks.
Can peony receive excessive sunlight?
Peonies, like any flower, can receive excessive sunlight. Even though this is less of an issue than it would be with other kinds of flowers, it’s still necessary to watch out for sunburns on your plants. The edges of flower petals or leaves that are brown are classic indications of sunburn.
- Peonies can receive too much sunlight.
- The most noticeable symptom of excessive sun exposure is brown leaf edges.
- Offer your peonies midday shade if you observe any of their parts turning brown.
- The greatest item for providing peonies with temporary shade when they are burnt by the sun is a row cover or shade cloth.
If you ever detect any browning, give your peony some shade during the day. Until they start to look healthy again, cover them with this row cover. The afternoon is the ideal time to shade your peonies. This is because the sun is at its strongest and the temperatures are typically the highest at this time. Your peony will benefit and have a chance to recover if you protect them now.
How much water and sunlight do peony require?
Therese Sprauer of Brooks Gardens reminds us that peonies are long-lived, low-maintenance, deer-resistant flowering perennials that thrive in our Northwest climate. The recent mild weather has opened the door for plenty of early season bloom this year.
The family-run Brooks Gardens features a historic bearded iris collection in addition to more than 300 different species of peonies, including heirloom and contemporary varieties.
The private peony fields and iris gardens are free to visit from 10 a.m. to 6 p.m. every day from April 26 through June 22 at 6219 Topaz Street NE in Brooks, Oregon.
Following are some advice from Sprauer for novice peony growers:
Peonies should be planted in a sunny, well-drained area. In order to produce an abundance of blooms, peonies need at least a half day of direct sunlight. If necessary, place plants on miniature “hills” to improve drainage. Peonies grow in clay soil, thus there is no need to adjust the soil.
Prepare: Make a good, 12-inch-deep by-12-inch-wide hole for your peony. Re-fill the hole with the earth you dug out earlier using a spade. That’s correct, re-fill the area with recently spaded soil. Just enough dirt should be removed to accommodate your peony or root plant.
Plant peony roots close to the ground level (not very deep). The top of the root, just below the ground’s surface, will contain the buds (eyes) of the root. The root’s fleshy portion, which resembles a carrot in some ways, will be facing downward or at an angle into the hole.
Soil should only cover the eyes by 1 to 2 inches on the peony root. The eyeballs will be barely below the surface. Too much planting depth can hinder development. Remove the pot from a peony before planting it, and place the peony so that the top of the root ball is level with the ground and is barely covered by soil.
Water: Give your newly planted plant a drink. See if the root has buried itself deeper. If it did, pull the root, tuck a bit of soil behind it, and move the peony root so the eyes are slightly below the surface. The first summer, water sparingly; once established, peonies are quite drought tolerant.
Care: Some gardeners never fertilize peonies, while others provide a small amount of flower fertilizer each spring. Cut the stems to the ground in the fall and get rid of the garden’s old leaves and stalks. Each spring, the peony plant’s eyes will emerge. Peonies don’t need to be separated after decades of growth in the same location.

Why is my new peony dying, exactly?
Hi Denise, My peonies are losing color. One of the three groups didn’t materialize at all in the spring. Then one of the other plants sprouted, produced one bloom, and then promptly withered away. My third plant is now on the verge of dying. My granny owned these plants. Are they permanently lost?
We recently noticed the mulch in this same bed being entirely turned when we got up. The bed appeared to have been flipped and scraped. Is this the work of raccoons, skunks, or might it be a turkey?
To Nikki: The peonies come first. Your peonies seem to have a fungus-related illness. Peonies are commonly infected by the fungus known as botrytis blight. It can cause later spring larger buds to turn brown and fresh spring stems to abruptly droop and fall over.
According to Virginia Tech extension plant pathologist Mary Ann Hansen, big, irregular dark brown blotches and large, fluffy masses of gray-brown fungus spores can occasionally be seen on the leaves. In more severe situations, botrytis can also result in crown and root rot.
But there is a cure, according to Mike Ecker, the Dawes Arboretum’s director of horticulture.
“Use a fungicide with a botrytis label on peonies in the spring. Some are also appropriate for fall applications. After that, remove and clean up all plant debris.
According to Brad Kiger, the Franklin County wildlife officer for the Ohio Department of Natural Resources, a turkey is most definitely not to blame for the oddly changed mulch.
“They are currently highly active, which is a major problem at this time of year. They destroy gardens and lawns in search of grubs.
Hi Denise, The plant in the attached photo is one that I’ve been attempting to identify for a year.
With the winter, the plant withers away to the ground. Every spring, it returns, and if I don’t cut it back, it will cover the area around the front entrance. It has huge leaves, a lovely purple blossom, and the scent of violets.
It has already begun to spread everywhere. We adore it, but how can we preserve it in a location?
Charlie, please: Your plant is a passionflower vine, which is unquestionably a hardy species in our environment. However, as you might have imagined, keeping it under control and contained can be a full-time job.
If you intend to maintain your vine and merely wish to contain it, “Garden consultant Deb Knapke advised digging up and removing the seedlings from any areas where you don’t want them to grow.
As soon as fruit starts to form on the vine, pluck it and throw it away to slow growth.”
Keep it from going to seed.
Be aware that you will need to carefully remove seedlings in places where the plant is undesirable for years.
Hi Denise, My ash tree is reportedly infested with clearwing borers. Can you describe these borers and the best way to get rid of them from the tree? Will the tree be felled?
Hi Helen, Ash, dogwood, viburnum, birch, and pine are just a few of the trees and shrubs that clearwing borers eat. They are native borer species. According to Chris Ahlum, an arborist of Ahlum & Arbor in Hilliard, native borers normally only attack dead, dying, recently planted, or stressed trees, unlike emerald ash borers, which attack any ash tree. They will probably cause the tree to die if not handled.
“Imidacloprid (trunk injections) does not work against clearwing borers if you have been treating your trees for the emerald ash borer; however, TREE-age will work against both borers.
Although a foliar spray can be used to treat them as well, Ahlum suggests a trunk injection.
Hi Denise, Two crab apple trees that we own have very few leaves and a black scab. Please let me know what the best plan of action is for treating this.
Greetings, Ray and Connie. The cold, damp spring has made apple scab quite common this year.
“According to Ahlum, this fungus typically infects trees in the spring but only produces leaf spots and leaf droppage in the summer.
Once the fungus is on the leaves, there is little that can be done to treat or remove it. However, the fungus can be prevented and controlled by using a series of three fungicide applications in the spring, from early April through May.
Rake up and get rid of all the fruit and leaves that have fallen from the tree till then. According to Ohio State University Extension, the fungus can survive the winter on the fallen leaves, and removing the leaves lowers the amount of spores that could restart the disease cycle in the spring.
Hi Denise, We used to have a lovely stand of hollyhocks, but this year they started to have issues. The tops of the leaves have reddish-brown patches, while the bottoms of the leaves have bumps that match the spots. The plants don’t produce as many flowers as they once did. I searched for insects but found none, despite spraying with Sevin and Bt, which had no effect. Can you offer me a diagnosis and a treatment?
Hello, Bill It’s challenging to identify your plants without seeing them, but hollyhock rust is most likely the cause. It is the most prevalent hollyhock issue, and the fungus that causes it. Older foliage is immediately killed off as it quickly spreads from leaf to leaf.
To manage it, “As the fungus overwinter in plant detritus, Knapke advised cleaning up and getting rid of all the old leaves and stems. Then, you can either get rid of the plants and think about “To stop further outbreaks, plant something else there that is not a member of the Malvae or Malvaceae family.
According to Virginia Tech Cooperative Extension, the plants may also be sprayed with a fungicide comprising chlorothalonil, mancozeb, trifloxystrobin, or myclobutanil at the first indication of disease.
