Peonies are enduring garden favorites that are well-known for their lavish, early-summer blossoms. They are dependable plants that bloom for generations with little care and have an extraordinarily long lifespan. Peonies are unmatched as cut flowers. They are beautiful in their natural beauty and have a soft, enduring perfume, whether they are grown alone or in mixed bouquets.
Start with a Better Bulb
It’s simple to discern quality differences between two peony plants when you compare them side by side. Grade #1 peony, as displayed at far left, are provided by Longfield Gardens. Right on this page is a peony of grade #2. The larger root requires less time to mature into a robust plant that bears several blossoms.
Plan for Success
Peonies are low maintenance and incredibly simple to grow. Here are some pointers to assist you achieve the greatest outcomes.
Peonies thrive in the sun and perform at their best when they receive at least 6 hours of direct sunlight each day. It is preferable to put your peonies in the most sunny area possible because the more sun they receive, the better their blooms will be.
Zones 3–8 are suitable for peonies’ winter hardiness. Cold winter climates are excellent for their growth and flowering. Zones 8 may be difficult for them, while zones 9 and warmer are not advised for them. Check your hardiness zone now. The USDA Hardiness zone map can be found here.
Soil: Loose, fertile, well-drained soil is ideal for growing most plants, including peony. By incorporating compost and an all-purpose fertilizer during planting time, you can enhance the condition of your soil. Planting should not be done on wet or compacted soil.
When to Plant: Spring or fall are both suitable times to plant bareroot peonies. The plants can withstand frost, so you can plant them two to three weeks before the last day of frost. You can plant potted peonies at any time of the growing season.
How to Plant Peonies
Make a 12-by-12-inch hole. Compost and general-purpose granular fertilizer should be added after loosening the soil at the bottom of the hole (follow package directions).
Place the peony root in the hole with the eyes (the growth points) no lower than one inch below the surface of the soil. Peonies that are planted too deeply may continue to grow but not blossom. Add soil over the root and water as necessary.
Planting Tips for Peonies
Peonies need full sun in order to produce a profusion of blossoms. Even though certain types may withstand moderate shadow, fewer flowers bloom in general when there is less light.
Peonies should be planted in soil that is fertile, well-drained, and has a pH range of neutral to slightly alkaline. They will eventually grow a substantial root system and become challenging to relocate. Spend some time placing your peonies in a location where they can flourish for many years. The plants are reasonably drought resistant once they are established.
Where to Plant Peonies
Continual Gardens Perennial gardens work well with peonies. Their year-round gorgeous dark green leaves. Peony leaves occasionally turn crimson or gold in the fall.
Fence lines and hedges To create a low hedge for enclosing a space, defining one side of a garden, or edging a walkway, peonies can be planted in a row. They also look fantastic when planted at the bottom of a chain link or split rail fence. As a sturdy fence will restrict airflow around the plants and increase their susceptibility to foliar diseases, avoid growing them next to one.
Plantings for the foundation and shrub borders The presence of a peony is comparable to that of a tiny shrub. Peonies may grow practically anyplace in your landscape as long as they are planted in well-drained soil, receive enough light, and have sufficient air circulation.
What to Expect from Peonies
All peonies bloom in the first few weeks of summer, however each cultivar blooms at a different period. The peony season can be prolonged by a month or more if you plant a mixture of early, mid, and late season bloomers. Other early summer perennials like iris, alliums, and roses pair well with peonies. The greenery keeps borders looking full and gives other flowers a lush background.
Most peony mature at least three feet tall and three feet wide, depending on the type. Therefore, it’s crucial to provide them freedom to expand. Peonies will maintain their flowers straight if a support cage is placed all around them. Use a pre-made peony support or create your own from steel or mesh reinforcing wire or wood slats. Early in the spring, before the plants reach a height of 12 inches, supports should be installed.
Carefree peony plants that hardly ever experience insect or disease problems. A young peony plant needs two to three years to become established, but once it does, it will reliably blossom each year.
Fantastic cut flowers are peonies. The majority of cultivars are also incredibly fragrant, and they remain for days in a vase. When the buds are in the “marshmellow” stage, peony stems can be removed and kept in water in the refrigerator for a few weeks. After many days, the buds on the stems brought into room temperature will begin to open.
Caring for Peonies are they Bloom
Use scissors to cut off the wasted flower heads and the top six to eight stems once the blossoms have faded “that stem. This will prevent the plants from forming seed heads and keep the plants looking tidy. The plants will be able to produce the energy they require for the blossoms of the following year if as little foliage as possible is removed.
When the leaves start to turn yellow in the fall, trim all the stems to within an inch or two of the ground.
When the stems are about 6 inches long in the spring, fertilize peonies “tall. Around the base of each plant, dispense roughly a half cup of all-purpose granular fertilizer. To avoid having the eyes buried too deeply, remove any mulch or other debris from the plant’s crown.
How to Divide a Peony
Peonies can stay undisturbed for several years in the same location. If the plants must be moved, do so in the fall when they are beginning to enter dormancy rather than in the spring when they are just starting to grow again. Trim the leaves, which may be up to three feet wide, then carefully remove the entire root ball. Dig carefully, avoiding uprooting any roots, and dig deeply. Replant right away, and give it lots of water.
Plant division can be done in the fall or very early in the spring. One method is to remove the entire root ball as previously said, then place the clump on a tarp. After cutting the clump into sections with a sharp knife, quickly replant each section. Work swiftly and gently, causing the fewest potential injuries to the fleshy roots.
The alternative is to cut one or more portions of root from the mother plant using a sharp spade. Once more, plant these divisions again right away, and during the first growth season, irrigate as necessary. Though you may often anticipate losing at least one season of blossoms, plants will recover more quickly the less the roots are touched.
Peony Pests and Diseases
Pests and illnesses rarely affect peonies. Buds can occasionally become black and shrivel as if they have been scorched by a fungus called botrytis. Young shoots and entire stems may turn black as a result of the disease. Wet weather worsens infection, as it does with all fungus-related illnesses. Take away and discard any tissues that are harmed. The greatest method of management is prevention; discard wasted blooms as soon as you can, abstain from overhead irrigation, and avoid crowding plants to promote good air circulation.
Peony buds are coated in a slightly sweet, sticky material just before they blossom. This will frequently draw ants, who enjoy the tasty treat. The ants are not necessary for peonies, yet they do not harm them in any way. It benefits both parties. Simply shake the flowers or submerge them in cool water if you plan to cut them and don’t want to attract ants into your house.
Check to see if your climate is conducive to producing peonies before planting one. These shrubs have a long lifespan and require a very cold winter to flower. According to a general rule of thumb, peonies require thirty consecutive days below freezing in order to reliably bloom for you, despite the fact that certain gardeners in more temperate locations have occasionally had some success. Climate zones 3–7 are ideal for growing garden peony. For optimum results, gardeners in zone 8 should choose peonies that bloom early, as this will allow their plants to fully blossom before the summer’s intense heat arrives.
I am aware of how eager gardeners in Florida and Southern California are to cultivate peonies. Don’t let a plant that requires a climate so dissimilar from your own crush your heart. One of the two reasons why peonies don’t blossom is that there isn’t enough winter chill.
Peonies can be planted well in the fall or the spring, but the fall is when they establish themselves the best. Six weeks before the first hard ground freeze, make sure you pant.
When choosing the location for your peony planting, keep in mind that you are making a long-term investment in the aesthetic appeal of your garden. Peonies are genetically predisposed for longevity since they can grow and bloom for up to a century. They have a broad perspective on life. For the first spring after planting, don’t anticipate blossoms. You could be surprised by one or two! The bloom production is quite low during the first few seasons, but it increases. In the third year, watch for bushes covered in blossoms!
The roots of peonies do not want to be disturbed. This explains why the initial bloom production is so meager. A healthy peony that consistently produces heavy flowers every year could be dug up and replanted just three yards away, but the bloom production would plummet and the time it took to reach full bloom would be almost identical to if it had been planted for the first time. So make sure you plant it where you want it to thrive!
Where there will be direct sunlight for at least eight hours per day, plant your peony. Plant for morning and afternoon sun in regions with extremely hot summers, but offer some light shade during the hottest part of the day.
Peonies may grow in a variety of soil types. Dig a hole 12 to 18 inches deep, breaking up any compacted soil, and add compost, dry grass clippings, and dead leaves to thick clay to improve the soil before planting your peony. Add amendments as necessary to promote proper drainage, along with about a cup of bone meal that has been thoroughly incorporated into the ground at the bottom of the hole.
Look for the “eyes” on your peony’s naked roots. These are the locations where new growth will form, much like the eyes on a potato. On a peony, the eyes are frequently (though not always) a bright pink swelling. Take note of the side that has the most eyeballs; when you plant it, you want that side up.
A climate with enough winter frost and the proper planting depth are the two most crucial criteria for peony to bloom freely.
Create a sizable dirt cone in the hole you excavated, firming it down as you go to get rid of air pockets and raising the top of the cone almost to the level of the ground. With its roots dangling down, place the peony at its naked base on top of the cone. Place it so that the side that has the most eyes is up. Backfill your peony root with loose soil, covering it to a depth of no more than 1/2 to 1 1/2 inches. It’s crucial that this depth is shallow. Your peony plant will still grow robust and healthy if it is planted deeper, but it will produce few or no blooms. The most common reason for impaired blooming in climates with appropriately cold winters is planting peony roots too deeply.
Check the depth of your peony root once more and level the dirt with the surrounding earth. If it is deeper than 1 1/2 inches, make the necessary adjustments and water it thoroughly. Once the water has been completely absorbed, check the peony root’s depth once more to make sure it hasn’t sunk any lower into the earth.
Now that your peony has been expertly planted, let’s go over the maintenance you need to provide it.
Rain will collect in the huge peony blossoms, making them heavy enough that the stems cannot support them. Particularly with the “bomb” flower shape variants, this is a problem. Finding your peony blooms finally open only to find yourself face first in the dirt is a sad letdown. When you first plant your peony or in the early spring when the first signs of new growth appear, add a ring-style support. The lattice will support new growth as it climbs up through it, hiding the ring in the process.
Give your peony plant a modest amount of watering. Recognize that fewer, deeper waterings are ideal since they will encourage broad, strong roots.
Apply an all-purpose fertilizer annually and top it up with compost for the greatest results. Mulch your peony sparingly; otherwise, the plant will act as though it was buried too deeply.
Although technically speaking, peonies do not require pruning, trimming them back in the late fall helps keep the garden looking neat and avoids any insect or disease damage from overwintering in the plant. Choose the smaller branch to be clipped all the way to the base when two branches cross and brush against one another. Insects or diseases can enter through the weakness created by that point of contact.
One of our customers just commented this morning, “I adore growing peonies, but I simply dread the ants!” Gardeners frequently express this complaint. But I want to defend the ants, who provide a vital service to the peony in return for food that is prepared expressly for them.
The plant expends a great deal of energy and resources in order to produce each massive, fragrant peony blossom. These flowers contain an abundance of nutrients that many insects would love to consume, depriving the plant of the ability to reproduce and leaving an unattractive mess in its stead. However, nature has a remedy for this issue! Peony buds make a pleasant nectar specifically to draw ants, who subsequently destroy any insects that are consuming the buds and leave the plant strong and attractive. The peony plant calls ants to defend it in return for the ants’ protection in exchange for tasty nectar.
Spraying pesticides on your peony won’t help, as they serve a useful purpose. Cut peony stems when the bud is still tightly closed. Take it inside and clean the ants off. The stem will fully bloom in your vase if you put it in lukewarm water.
I adore peony, but the climate where I live and garden makes it impossible for me to cultivate them. Can you let me experience them via you?:) If you will be planting peonies this fall or if you have any queries, kindly let me know in the comments. I’m happy to assist!
