In the spring, plant peonies as soon as the ground is no longer frozen. While there’s still a chance of frost, it would be a good idea to put a layer (1–2 inches) of mulch over the planting area. If your peony already has foliage, you’ll want to cover it with a sheet on nights when there’s a danger of frost.
When there’s no longer a risk of frost, remove the mulch. (A thin layer can be left to help conserve moisture, but peonies don’t like to be planted too deeply.) Your peony likely won’t bloom this year, but should be well established by next spring!
