When to Transplant Peonies

When to Transplant Peonies

Short Answer: The best time to transplant peonies is in the fall, ideally in September or October. This allows the plant to establish its roots in the new location before the ground freezes and while the soil is still warm. Avoid transplanting in the spring when they are emerging and starting to flower, as this can stress the plant and impact its blooming.

Peonies are known for their beautiful spring flowers. However, after 10 to 15 years, the blooms may slow down. When this happens, it’s time to dig, divide, and transplant the peonies in your garden. You can replant a portion of the original peony and its divisions in the same part of the garden or choose new locations. Herbaceous peonies are great for sharing with friends and family, making them perfect pass-along plants.

Herbaceous Peony vs. Tree Peony

Herbaceous garden peonies are relatively easy to divide and transplant. Tree peonies, however, don’t take well to being disturbed, so it’s best to leave them be.

When to Transplant Peonies

The best time to transplant herbaceous peonies is in September, when they’re past their summer growth and entering winter dormancy. But it’s also possible to dig and plant the entire root ball in the spring before the plants start to sprout new growth for the season. Disturbing peonies at any other time of the year will likely stress them out too much for them to survive.

How to Divide Peonies

First, gently dig up the plant, keeping as many roots as possible. You’ll pull up a lumpy crown with small, reddish buds (eyes) poking up from it and stringy roots trailing below. Gently shake or wash most of the soil off the roots. If the crown has at least six eyes, you can divide it to energize the peony and get more flowers in the future. Use a spade with a sharp blade to slice the crown into pieces with at least three eyes each.

Where to Transplant Peonies

Your peonies will give you the most flowers if they get at least 6 hours of sun daily. You can place them in a pinch in part shade, but you’ll see fewer flowers. As for soil, anything will do as long as it drains well. Don’t plant them where the rain puddles in your garden.

Peonies need good airflow around them to prevent powdery mildew, so dig the new holes at least three feet apart. The holes should also be wide enough to allow new roots to grow. As for depth, peonies are fussy about being planted close to the surface; the eyes should be only a couple of inches underground, or the peony will not bloom. Hold the peony crown to almost surface level and pat the freshly dug soil around the peony roots and over the top of the crown.

Caring for New Peony Transplants

After planting, water the divisions thoroughly. Peonies need to be watered weekly until the ground freezes in the fall. You must step in with your trusty garden hose if nature doesn’t supply weekly rains. In November, spread 4-6 inches of mulch over your peonies to stabilize soil temperatures through winter. In the spring, remove the mulch and spread it around your garden beds or add it to your compost pile.

Peonies are known as slow starters, so you likely won’t see maximum blooms for 2-3 years. But once they’re in gear again, the transplanted peonies will be your garden all-stars for many years.
