IF you Can’t Plant Your Peony right Away… do this!
Can I Save a Peony If I Can’t Plant It Right Away?
One of the questions I hear from peony lovers is,
“What do I do if I have to move my peony, but I can’t plant it right away?”
Maybe you're moving to a new house. Maybe you’re working on new landscaping or construction. Or perhaps you dug up a special peony—one that belonged to your grandmother or has been growing in your garden for decades—and you simply can't bear to leave it behind.
The good news is: a dormant peony root is surprisingly tough. With the right conditions, you can hold it temporarily or even overwinter it if necessary until you're ready to plant.
If You Only Need to Store It for a Short Time
If you're talking about days or a few weeks, my preferred method is cold storage in the refrigerator.
After digging your dormant peony, gently remove excess soil and place the root in a plastic bag with slightly damp pine shavings. Peat moss is also a good option if you have some on hand. The shavings or peat should be damp—not wet. Close the bag loosely rather than sealing it airtight.
Then place it in the refrigerator.
The goal is to keep the root cool and slightly moist without allowing it to become soggy or dry out. Check it regularly for any signs of excessive moisture, mold or drying. If the shavings feel too wet, give the root a little more ventilation. If they are becoming dry, add a small amount of moisture.
Refrigeration provides a much more consistent environment than trying to guess what temperature your garage will reach. Recommendations for dormant bare-root plants generally call for temperatures in roughly the upper 30s to mid-40s, while avoiding both freezing and warm temperatures that could trigger growth.
What If I'm Moving in the Winter?
This is where things get a little different.
If you are moving in December, January or February and want to take a special peony with you, I would not simply put the bare root in a garage and hope for the best. Garages can experience large temperature swings, and a severe cold snap can freeze the root solid.
For a longer storage period, I recommend potting the peony.
Use a container large enough to comfortably hold the root system and a good-quality potting mix. Mixing some sand, gravel or bark chips into standard potting soil will help imrpve drainage and prevent root rot. Plant the peony at the proper depth, with the eyes about 1–2 inches below the soil surface. Water it thoroughly after planting so the soil settles around the roots.
Then comes the important part:
Keep the potted peony consitently cool.
A garage, shed, cold storage room or similar space can work if you can keep the temperature relatively stable at approximately 30–40°F throughout the winter.
I strongly recommend putting a thermometer in the space rather than relying on how cold it feels. Temperatures can fluctuate considerably in garages, especially during Minnesota winters.
Peonies require a period of cold temperatures for proper dormancy, and cold, stable storage is preferable to repeated freezing and thawing.
And What About Watering?
This is one place where people tend to overdo it.
Water the peony well when you initially pot it. Then leave it alone.
During the winter, check the pot occasionally. If the soil is still slightly moist, you don't need to do anything. If the entire pot has become very dry, give it a small amount of water.
Remember, the plant is dormant. It isn't actively growing and using much water. Keeping a dormant peony constantly wet can create more problems than allowing it to be slightly dry. Container-grown peonies are particularly susceptible to root problems when kept too wet during winter.
When Spring Arrives
Once the ground has thawed and your new planting location is ready, move the peony into its permanent home.
Plant it with the eyes about 1–2 inches below the soil surface. Don't be tempted to plant it deeply—one of the most common reasons peonies fail to bloom well is being planted too deep.
And don't worry if your transplanted peony doesn't look spectacular right away. Moving a mature peony is a big disturbance, and it may take a season or two to settle back in and flower normally.
The bottom line:
Need to hold a dormant root for a short time?
→ Loosely bag it with slightly damp pine shavings or peat moss and keep it in the refrigerator. Check it regularly.
Need to save a peony through the entire winter?
→ Pot it up, water it well once, and keep it somewhere that stays approximately 30–40°F, without major temperature fluctuations. Monitor the temperature with a thermometer and water only if the pot becomes very dry.
Sometimes a peony isn't just a plant. It's a piece of the garden you want to take with you.
