Peonies are one of the most beloved and iconic flowers in the world of gardening. These stunning blooms are known for their large, showy flowers and lush, green foliage. With proper care and attention, peonies can thrive in a variety of environments and provide beautiful blooms for years to come. In this article, we will explore the ins and outs of growing peonies, including the best conditions, soil requirements, and care techniques.
Choosing the Right Peony Variety
There are several different types of peonies, each with its own unique characteristics and growing requirements. The most common types of peonies include herbaceous peonies, tree peonies, and intersectional peonies. Herbaceous peonies are the most popular type and are known for their large, showy flowers and lush foliage. Tree peonies, on the other hand, have a more upright growth habit and produce smaller, more delicate flowers. Intersectional peonies are a cross between herbaceous and tree peonies and offer the best of both worlds.
When choosing a peony variety, consider factors such as bloom color, flower size, and growth habit. Some popular varieties include ‘Sarah Bernhardt’, ‘Festiva Maxima’, and ‘Karl Rosenfeld’. It’s also important to choose a variety that is well-suited to your climate and growing conditions.
Preparing the Soil
Peonies prefer well-draining, rich soil that is high in organic matter. To prepare the soil for planting, start by testing the pH level. Peonies prefer a slightly acidic to neutral soil pH, ranging from 6.0 to 7.0. If your soil is too alkaline, you can add elemental sulfur or peat moss to lower the pH.
Next, add a 2- to 4-inch layer of compost or well-rotted manure to the soil. This will help to improve the soil’s structure and fertility. Mix the compost or manure into the top 12 inches of soil, taking care not to over-till the soil.
| Soil pH | Recommended Amendment |
|---|---|
| Too alkaline (above 7.0) | Elemental sulfur or peat moss |
| Too acidic (below 6.0) | Lime or dolomitic limestone |
Planting Peonies
Peonies are typically planted in the fall, about 6 to 8 weeks before the first frost. This allows the roots to establish themselves before the ground freezes. Plant the peony roots 1 to 2 inches deep, making sure that the eyes (small, swollen buds on the crown) are facing upwards.
Space the plants 3 to 4 feet apart, depending on the variety. Water the soil gently but thoroughly after planting, and keep the soil consistently moist during the first growing season.
Caring for Peonies
Peonies require minimal care, but there are a few things you can do to ensure they thrive. Water the plants regularly, providing about 1 inch of water per week. Avoid over-watering, as this can lead to root rot and other problems.
Fertilize the peonies in the spring, using a balanced fertilizer. You can also add a layer of compost or well-rotted manure to the soil around the plants. Deadhead the flowers as they fade, cutting them off at the base of the stem.

Pests and Diseases
Peonies are generally resistant to pests and diseases, but there are a few things to watch out for. Slugs and snails can be a problem, especially in damp environments. Use copper tape or crushed eggshells around the plants to deter these pests.
Botrytis and powdery mildew can also be a problem, especially in humid environments. Remove any infected leaves or stems, and treat the plants with a fungicide if necessary.
