What kind of plant is Peony?
Peonies are perennial garden classics, loved throughout the world for their extravagant, early summer blossoms. They are dependable, incredibly long-lived plants and will bloom for generations with little attention. As cut flowers, peonies have no rivals. Alone or in mixed bouquets, they have an elegant natural beauty and a delicate, unforgettable perfume.
Steps to planting Peonies
Growing zone- The best growing zones for peonies are typically USDA Hardiness Zones 3 through 8, which require a minimum amount of winter cold for proper dormancy and bloom. Peonies need at least 30 consecutive days of freezing temperatures to thrive. You can find your specific USDA Hardiness Zone by checking the USDA Plant Hardiness Zone Map.
Site selection- peonies requires 6-8 hours of direct sunlight and well-draining, fertile soil amended with organic matter like compost or manure. Ensure adequate spacing of at least 3-4 feet for good airflow and disease prevention, and choose a location with consistent moisture but no standing water to prevent root rot. While most peonies prefer full sun, some, particularly tree peonies, will benefit from dappled or afternoon shade in hotter climates.
Ground Preparation- Dig the planting hole 12-15 inches deep, mix in 2-4 inches of well-rotted compost or manure, and consider adding bone meal or other balanced fertilizers. Avoid planting too deep, and never use fresh manure.
Planting Peonies- plant the "eyes" or buds of the root no more than 2.5–5 cm (1-2 inches) below the soil surface to ensure blooms. Water the plant well after planting and keep the soil consistently moist, but not waterlogged, especially during establishment.
First year of care of Peonies
Disbudding the first and second year of blooms- it's generally recommended to disbud (remove) all small buds to encourage stronger root and foliage growth, establishing a more robust plant for future years.
Cutting back after the first frost- cut peony stems to 2-3 inches above the soil to reduce disease risk. Dispose of all clippings in the trash to prevent pests and fungal diseases from spreading in your garden.
Apply mulch cover for the first winter after first frost- you should apply a 1-2 inch layer of natural mulch (like straw, shredded leaves, or wood/bark) after the ground has frozen to protect the new root from the freeze-thaw cycle, but never cover the crown.
Remove mulch after first signs of growth- you should remove mulch from around your peony plants as soon as you see the first signs of new growth in early spring, as this helps the plants get sunlight and allows the soil to warm up, which is essential for healthy flowering
Apply organic fertilizer in the spring- spread a balanced or low-nitrogen blend, such as compost, well-rotted manure, bone meal, or a balanced organic granular fertilizer, around the drip line of the plant when new shoots are 2-3 inches tall.
Long Term Health of Peonies
Cut back after the first frost each year- you should cut back your peony plants to 2-3 inches above the soil line after the first frost each year to remove diseased foliage and protect the plant's health for the next season. This late-fall pruning helps prevent fungal diseases and is an important part of peony winter care.
Maintain the surrounding areas so that weeds don’t compete- To prevent weeds from competing with your peonies, apply a 2-3 inch layer of organic mulch in spring, ensuring it doesn't cover the crown of the plant, and remove any weeds manually before they go to seed.
When to cut buds for longest vase life- Cut peony buds for the longest vase life when they are in the "marshmallow stage," meaning they have some color but feel soft and slightly squishy when gently squeezed.
Deadheading blooms that weren’t cut-you should deadhead peonies by removing the spent blooms after they finish flowering to conserve the plant's energy for root development and foliage health, which supports next year's blooms.
Regular application of fertilizer each spring- regular fertilization in the spring is a common practice for peonies, using a balanced, low-nitrogen formula like 10-10-10 or 5-10-10 when new shoots are about 2-3 inches tall.
