Peonies are a popular choice for many gardeners due to their lush, vibrant blooms and their hardy nature. These perennial plants can live for up to 100 years if properly cared for, making them a long-lasting addition to any garden. In this guide, we’ll walk you through the process of planting peonies, from choosing the right location to caring for your plants after they’ve been planted.
Choosing the Right Peony for Your Garden
There are several types of peonies to choose from, each with its own unique characteristics. The three main types are herbaceous peonies, tree peonies, and intersectional peonies, also known as Itoh peonies.
Herbaceous peonies are the most common type and are known for their large, fragrant flowers. Tree peonies, on the other hand, are woody shrubs that produce smaller flowers but are still quite striking. Intersectional peonies are a hybrid of the two and offer the best of both worlds.
Herbaceous Peonies
Herbaceous peonies are the most popular type of peony and are known for their large, fragrant flowers. They come in a variety of colors, including pink, red, white, and yellow.
These peonies die back to the ground each winter and re-emerge in the spring. They typically bloom in late spring or early summer.
Tree Peonies
Tree peonies are a type of woody shrub that produces smaller flowers than herbaceous peonies. However, they are still quite striking and come in a variety of colors.
Unlike herbaceous peonies, tree peonies do not die back to the ground in the winter. Instead, they retain their woody structure year-round.
Intersectional Peonies
Intersectional peonies, also known as Itoh peonies, are a hybrid of herbaceous and tree peonies. They offer the best of both worlds, with large, fragrant flowers and a woody structure that does not die back in the winter.
These peonies are a bit more expensive than the other types, but many gardeners find them worth the investment.
Choosing the Right Location
Peonies thrive in full sun, so choose a location that gets at least six hours of sunlight each day. They also prefer well-drained soil. If your soil is heavy clay or tends to stay wet, you may need to amend it with compost or other organic matter to improve drainage.
Peonies are large plants, so make sure to give them plenty of space. Plant them at least three feet apart to allow for adequate air circulation and prevent disease.
Planting Your Peonies
Once you’ve chosen your peonies and prepared your planting site, you’re ready to plant. Here’s a step-by-step guide:
- Dig a hole that’s wide and deep enough to accommodate the roots of your peony. This will typically be about 18 inches wide and 12 inches deep.
- Place the peony in the hole with the eyes (the small, red buds on the root) facing upward. The eyes should be no more than 2 inches below the soil surface. If planted too deep, the peony may not bloom.
- Backfill the hole with soil, firming it gently around the roots. Water thoroughly.
- Mulch around the plant to conserve moisture and suppress weeds. However, keep the mulch away from the base of the plant to prevent rot.
Caring for Your Peonies
Peonies are relatively low-maintenance plants, but there are a few things you can do to ensure they thrive.
Watering
Peonies need a moderate amount of water to thrive. Water them regularly, especially during dry spells. However, be careful not to overwater, as this can lead to root rot.
Fertilizing
Peonies benefit from a light application of a balanced fertilizer in the spring. Avoid using high-nitrogen fertilizers, as these can encourage leafy growth at the expense of blooms.
Pruning
Herbaceous and intersectional peonies should be cut back to the ground in the fall to prevent disease. Tree peonies should not be pruned, except to remove dead wood or to shape the plant.
Common Peony Problems
While peonies are generally quite hardy, they can be susceptible to a few common garden pests and diseases.
Botrytis Blight
Botrytis blight is a common fungal disease that can affect peonies. Symptoms include blackened buds and stems and a gray, fuzzy mold. To prevent this disease, ensure your peonies have good air circulation and avoid wetting the foliage when watering.
Peony Wilt
Peony wilt is another fungal disease that can cause the stems and leaves of your peonies to wilt and turn black. If you notice these symptoms, remove and dispose of the affected plant material immediately.
Ants
It’s common to see ants on peonies, but they are not a cause for concern. Ants are attracted to the sweet sap produced by peony buds, but they do not harm the plants.
Conclusion
With their lush, vibrant blooms and hardy nature, peonies make a wonderful addition to any garden. By choosing the right type of peony, selecting the ideal location, and providing proper care, you can enjoy these beautiful plants for many years to come.
