Peony bulbs should be dug up carefully and stored properly to ensure they thrive year after year.
Knowing how to dig up and store peony bulbs is essential for keeping your plants healthy and ready to bloom again in the next growing season.
In this post, we’ll walk you through the best timing, tools, and storage tips for digging up and storing peony bulbs so you can enjoy beautiful peonies season after season.
When and Why You Should Dig Up Peony Bulbs
1. The Best Time to Dig Up Peony Bulbs
The best time to dig up peony bulbs is in the fall, usually between late September and early November after the peony plant has gone dormant.
Digging up peony bulbs at this point gives the plant time to store energy in its roots before winter arrives.
This timing also allows you to divide and replant the bulbs if needed, giving you a chance to propagate new plants.
2. Why Dig Up Peony Bulbs at All?
Although peonies can be left in the ground year-round, digging up peony bulbs every 3 to 5 years helps refresh the plants and prevent overcrowding.
Digging up peony bulbs lets you divide large clumps, remove dead or diseased roots, and promote stronger growth and bloom in future seasons.
Also, if your area has harsh winters with wet soil or freezing ground, digging up the bulbs and storing them properly can protect them.
The Step-by-Step Process of How to Dig Up Peony Bulbs
1. Prepare Your Tools and Work Area
Gather a garden fork or spade, garden gloves, pruning shears, and a clean, dry workspace to sort the bulbs after digging.
Having sharp tools and gloves makes the job easier and protects the bulbs and your hands during digging.
2. Cut Back the Foliage
Cut peony stems down to about 2-3 inches above the soil surface before digging.
This helps you see the base of the plant and makes handling the bulbs easier.
3. Dig Carefully Around the Plant
Use your spade or fork to dig about 12-18 inches deep around the peony clump.
Start digging about 6 inches away from where the stems emerge to avoid cutting into the bulbs.
Loosen the soil gently to lift out the entire rootball without damaging the bulbs.
4. Lift the Peony Clump Out of the Soil
Once loosened, carefully lift the peony clump out of the ground.
Shake the soil off gently so you can see the bulbs and roots clearly.
Avoid washing the bulbs with water as excess moisture can cause rot during storage.
5. Examine and Clean the Bulbs
Check for any damaged, mushy, or rotten sections and trim them away with clean pruning shears.
Healthy peony bulbs should be firm with visible “eyes” or buds that will sprout next season.
6. Divide the Clumps If Necessary
If your peony has grown into a large clump, divide the rootball into sections with at least 3 to 5 eyes on each piece.
This gives each division a good chance to grow strong.
Remember to use clean, sharp tools and be gentle to avoid bruising the bulbs.
How to Store Peony Bulbs Properly
1. Choose the Right Storage Medium
Store peony bulbs in a slightly moist but not wet medium such as peat moss, sawdust, vermiculite, or dry sand.
The medium helps regulate moisture and air around the bulbs, preventing rot and drying out.
2. Use Proper Containers
Place the bulbs in cardboard boxes, wooden crates, or breathable mesh bags to allow good air circulation.
Avoid plastic bags or sealed containers which trap moisture and can cause rot.
3. Store Peony Bulbs in a Cool, Dark Place
Peony bulbs store best at temperatures between 35-45°F (1-7°C).
A basement, garage, or root cellar usually offers the perfect cool environment.
Keep bulbs away from direct sunlight and freezing temperatures.
4. Monitor Moisture Regularly
Check your stored peony bulbs periodically to ensure the storage medium remains slightly moist.
If the medium feels dry, lightly mist it with water, but avoid making it wet.
Remove any bulbs that show signs of rot, mold, or dryness to protect the rest.
Replanting Your Peony Bulbs
1. Choose a Suitable Planting Location
Peonies love full sun and well-drained soil for the best blooms.
Avoid overly wet or shaded spots, and prepare the soil by loosening and amending it with compost.
2. Plant Peony Bulbs at the Right Depth
When replanting, place the peony bulbs so the eyes are about 2 inches below the soil surface.
Planting too deep can delay blooming, while too shallow might expose the bulbs to damage.
3. Water After Planting
Water the newly planted bulbs deeply to settle the soil around the roots.
Keep the soil moist but not soggy during the first growing season until the plant establishes.
4. Mulch for Protection
Apply a layer of mulch around the base of the plant to retain moisture and regulate soil temperature through winter.
Avoid piling mulch directly on the crowns to prevent rot.
So, How to Dig Up and Store Peony Bulbs?
Digging up and storing peony bulbs is best done in the fall when plants are dormant to ensure later healthy growth.
The process involves carefully digging around the peony, lifting the bulbs, cleaning and dividing them if needed, and then storing them in a cool, dark place with the right moisture levels.
Using peat moss or sawdust in breathable containers helps keep the bulbs from drying out or rotting during storage.
Knowing how to dig up and store peony bulbs properly ensures your peonies come back strong and vibrant every year, brightening your garden with their beautiful blooms.
By following these steps, you’ll get the most out of your peony plants and enjoy their stunning flowers season after season.
Happy gardening!
