Understanding Peonies for Ann Arbor’s Climate
Peonies are perennial plants, meaning they come back year after year, often for decades! They are known for their large, showy flowers that come in a dazzling array of colors, from delicate pinks and whites to deep reds and vibrant corals.
Michigan, and Ann Arbor specifically, experiences cold winters and warm summers. This provides the essential chilling period many peonies need to set buds for the following spring. This climate is generally excellent for herbaceous peonies, which die back to the ground each winter. Tree peonies, while a bit more sensitive, can also thrive with the right site selection.
Don’t worry if you’re new to gardening; peonies are surprisingly resilient and rewarding. With the right conditions, they are low-maintenance stars.
Selecting the Perfect Spot for Your Peonies
Location, location, location! This is arguably the most crucial step for happy peonies. They have a few non-negotiables that will set them up for success in Ann Arbor.
Peonies absolutely adore sunshine. Aim for a spot that receives at least 6-8 hours of direct sunlight per day. Too much shade, and you’ll get fewer, smaller blooms. While they can tolerate some dappled afternoon shade in the hottest part of summer, full sun is ideal.
Good air circulation is also key. Avoid planting them too close to walls, fences, or dense shrubs. This helps prevent fungal diseases, a common concern for peonies, especially during our humid Michigan summers.
These plants dislike competition for nutrients and water. Ensure your chosen spot doesn’t have aggressive tree roots or other plants that will vie for resources. This is especially important when establishing new plants.
Drainage is paramount. Peonies absolutely hate wet feet. If your garden tends to hold water after rain, consider amending the soil with compost or planting on a slight mound to improve drainage. Soggy soil can lead to root rot, which is a death sentence for peonies.
Choosing the Right Peony Varieties for Your Garden
With thousands of cultivars, picking the right peony can feel overwhelming. For Ann Arbor gardens, focus on varieties known for their hardiness and bloom reliability.
Herbaceous Peonies: The Classic Choice
These are the most common type, dying back to the ground each winter and regrowing in spring. They are generally very cold-hardy and well-suited for our climate.
- Lactiflora Varieties: These are the classic, late-blooming peonies with large, fragrant flowers. ‘Sarah Bernhardt’ is a beloved, showy pink variety, while ‘Felix Crousse’ offers a stunning deep red.
- Intersectional (Itoh) Hybrids: These are a cross between herbaceous and tree peonies, offering the best of both worlds. They have the sturdy stems of tree peonies but die back like herbaceous ones. They are also known for their incredible bloom longevity and unique coloration. ‘Bartzella’ is a popular yellow Itoh, and ‘Cora Louise’ is a beautiful pale pink with red flares.
Tree Peonies: The Elegant Shrub
Tree peonies are woody shrubs that do not die back in winter and can live for many decades. They often bloom earlier than herbaceous types and have a more shrub-like appearance.
- Lohan and Rockii Hybrids: These often exhibit striking dark eyespots at the base of their petals and are known for their hardiness.
- Japanese Tree Peonies: While beautiful, some of these can be slightly less cold-hardy than other types and might benefit from a bit of winter protection in harsher Ann Arbor winters.
When purchasing, look for reputable nurseries that specialize in peonies. They can offer advice tailored to your specific microclimate within Ann Arbor.
Planting Your Peonies for Success
Planting is critical for establishing strong, healthy plants. Timing and depth are your best friends here.
When to Plant
The absolute best time to plant peonies in Ann Arbor is in the fall, from September through October. This gives the roots time to establish themselves before the ground freezes, allowing them to be ready to go come spring.
While spring planting is possible, it’s generally less ideal. If you must plant in spring, do so as early as possible, as soon as the ground can be worked. This gives them a full growing season to get established.
How to Plant
Dig a hole that is about 18-24 inches wide and 12-18 inches deep. This provides ample space for the roots to spread out.
If you have heavy clay soil, amend the hole with a generous amount of compost and well-rotted manure. This improves drainage and adds nutrients.
For herbaceous peonies, the most common mistake is planting them too deep. The ‘eyes’ (the small red buds on the root system) should be no more than 1-2 inches below the soil surface. Planting too deep is a primary reason for poor blooming.
For tree peonies, plant them slightly deeper, with the graft union (where the scion is joined to the rootstock) about 4-6 inches below the soil surface. This encourages the scion to root itself.
Gently place the peony in the hole, backfill with soil, and water thoroughly. Mulching lightly after planting can help retain moisture and regulate soil temperature.
Essential Peony Care in Ann Arbor
Once planted, your peonies will reward your efforts with stunning blooms for years to come. Consistent care, especially in the early years, is key.
Watering
Newly planted peonies need consistent moisture to establish their root systems. Water them deeply once or twice a week, especially during dry spells, ensuring the soil is moist but not waterlogged.
Established peonies are quite drought-tolerant, but they will appreciate a good watering during prolonged dry periods, especially when they are in bud and bloom. Avoid overhead watering if possible, as wet foliage can encourage disease.
Fertilizing
Peonies are not heavy feeders. In fact, over-fertilizing can lead to lush foliage but fewer flowers. A light feeding in early spring, as new growth emerges, is usually sufficient.
Use a balanced, slow-release fertilizer or a compost-rich organic fertilizer. Avoid high-nitrogen fertilizers, which can promote leaf growth at the expense of blooms.
You can also top-dress with compost annually in the fall. This provides a slow release of nutrients and improves soil structure.
Support for Blooms
Many peony varieties, especially those with large, double blooms, can become quite heavy when laden with flowers. To prevent them from flopping over, consider using peony supports.
These can be simple metal rings that are placed around the plant in early spring, or more elaborate cages. The stems will grow up through the support, keeping the blooms upright.
Deadheading and Fall Cleanup
Once the flowers have faded, deadhead them by cutting the stem back to a strong leaf. This prevents the plant from putting energy into seed production and keeps the garden looking tidy.
In the fall, after the first hard frost, it’s crucial to cut back herbaceous peonies. Remove all the foliage to the ground. This helps prevent the overwintering of fungal spores that can cause issues the following spring.
Tree peonies do not need this fall cleanup; their woody stems remain throughout the winter.
Common Problems and Solutions for Peonies in Ann Arbor
Even the best-tended gardens can encounter issues. Here are some common problems you might face with your peonies in Ann Arbor and how to address them.
Pests and Diseases
Powdery Mildew: This is a common fungal disease, especially in humid conditions. It appears as a white, powdery coating on the leaves. Good air circulation and avoiding overhead watering can help prevent it. If it becomes severe, consider using a fungicide, but remember to remove and discard infected foliage.
Botrytis Blight: This can affect buds, stems, and leaves, causing them to rot and turn brown or black. It thrives in cool, wet conditions. Remove affected parts immediately and ensure good air circulation. Fall cleanup is critical for managing this.
Ants: Don’t panic if you see ants on your peony buds! They are attracted to the sweet nectar produced by the buds and are generally not harmful. In fact, they can sometimes deter other pests.
Lack of Blooms
This is a common frustration for peony growers, but often has simple solutions.
- Planted too deep: As mentioned, this is the most frequent culprit. If your peony isn’t blooming, gently dig it up and replant it with the eyes closer to the surface.
- Too much shade: Ensure your plant is getting at least 6 hours of direct sun.
- Too much nitrogen: Over-fertilizing with high-nitrogen feeds can lead to lush foliage but no flowers.
- Immaturity: Newly planted peonies, especially those divided from larger clumps, may take a year or two to establish and start blooming vigorously. Be patient!
- Competition: Roots from nearby trees or shrubs can starve your peony of nutrients and water.
Dividing Peonies: When and How
While peonies are long-lived, you may eventually want to divide them to rejuvenate older clumps or to share with friends.
The best time to divide peonies is in the fall, similar to planting. This allows the new divisions to establish roots before winter.
Carefully dig up the entire clump. Use a sharp spade or knife to divide it into sections, ensuring each section has at least 3-5 healthy ‘eyes’ and a good portion of root. Discard any rotted or diseased sections.
Replant the divisions immediately at the correct depth, or pot them up to plant later in the fall. It’s often recommended to wait a year after division before expecting abundant blooms.
Enjoying Your Peonies in Ann Arbor
There’s nothing quite like the first sight of peony blooms in late spring or early summer, a true herald of warmer days.
These magnificent flowers are perfect for cutting and bringing indoors. For the longest-lasting cut flowers, harvest them when the buds are just beginning to show color and feel soft to the touch, like a marshmallow. Cut them in the cool of the morning.
Peonies also make a stunning statement in the landscape. Plant them along a walkway, in a prominent border, or as a focal point in your garden design.
Whether you’re a seasoned gardener or just starting out, cultivating peonies in Ann Arbor is a deeply rewarding experience. Their beauty, fragrance, and longevity make them a cherished addition to any Michigan garden.
Frequently Asked Questions About Peonies in Ann Arbor
Why are my peonies not blooming?
The most common reasons are planting too deep, insufficient sunlight, or immaturity. Ensure the ‘eyes’ are no more than 1-2 inches below the soil surface, the plant gets at least 6 hours of sun, and give it a couple of years to establish.
When should I cut back my herbaceous peonies?
Cut back herbaceous peonies to the ground in the fall, after the first hard frost. This helps prevent disease overwintering. Tree peonies should not be cut back in the fall.
Can I plant peonies in the spring in Ann Arbor?
While fall is the ideal planting time, spring planting is possible if done as early as the ground can be worked. However, fall planting generally leads to better establishment and blooming in the first year.
Are peonies deer resistant?
Peonies are generally considered deer resistant. Deer tend to prefer plants with more tender foliage and less potent fragrances.
How often do I need to fertilize my peonies?
Peonies are not heavy feeders. A light feeding in early spring with a balanced fertilizer or compost is usually sufficient. Avoid over-fertilizing, especially with high-nitrogen products.
