Calla lilies prefer to rest after their foliage yellows, so transplanting them during their dormant phase minimizes transplant shock. If you are wondering how to transplant calla lilies without losing blooms next season, the answer lies in timing and gentle handling. These rhizomes are tough, but they hate sitting in cold, wet soil during their sleep period.
Most gardeners move them in early spring or right after the leaves die back in fall. You can also dig them up, store them for winter, and replant in spring. This guide covers every method, from dividing crowded clumps to moving potted plants into garden beds.
Why Transplanting Calla Lilies Is Necessary
Calla lilies outgrow their space quickly. A single rhizome can multiply into a dense cluster within two years. When crowded, they produce fewer flowers and smaller leaves.
Transplanting also helps if your soil drains poorly. Calla lilies rot in soggy ground, so moving them to a better spot saves the plant. You might also want to relocate them for design reasons or to protect them from frost.
Signs Your Calla Lilies Need Transplanting
- Flowers are smaller than usual or absent entirely
- Leaves are yellowing in the center of the clump
- Rhizomes are pushing out of the soil surface
- The plant has been in the same spot for 3 or more years
- Water pools around the base after rain
If you see any of these, plan to dig them up soon. The best time is when the foliage has died back naturally. That signals the plant is storing energy for next year.
How To Transplant Calla Lilies
Follow this step-by-step process for the highest success rate. You will need a shovel, garden fork, pruning shears, and a bucket of water.
Step 1: Wait For The Right Season
In warm climates (zones 8-10), transplant in fall after leaves yellow. In colder zones, dig up rhizomes before the first hard frost. Store them indoors and replant in spring after the soil warms.
If you must move them while they are actively growing, do it on a cloudy day. Water the plant deeply the night before. Expect some wilting, but they usually recover.
Step 2: Prepare The New Location
Calla lilies need full sun to partial shade. Morning sun with afternoon shade is ideal in hot regions. The soil should be rich, loamy, and slightly acidic (pH 6.0-6.5).
Dig the new hole about 4-6 inches deep. Space holes 12-18 inches apart. Mix compost or aged manure into the removed soil. This gives the rhizomes a nutrient boost.
Step 3: Lift The Rhizomes Carefully
Insert a garden fork about 6 inches away from the plant stem. Gently pry upward, working around the entire clump. Do not pull on the leaves—they will snap off.
Shake off loose soil. You will see a cluster of fleshy, finger-like rhizomes. Some may be connected by thin roots. Separate them by hand or cut with a clean knife.
Step 4: Clean And Inspect The Rhizomes
Rinse the rhizomes with water to remove remaining dirt. Check for soft spots, mold, or dark blemishes. Healthy rhizomes are firm and pale yellow or cream colored.
Cut away any rotten parts with sterilized shears. Dust the cuts with sulfur powder or cinnamon to prevent fungal infection. Discard shriveled or mushy rhizomes—they will not grow.
Step 5: Divide The Clumps
Each division should have at least one growing point (a small bud or eye). Larger divisions bloom sooner, but even small ones will grow if they have a bud.
Trim the old foliage down to 2-3 inches. This reduces water loss and helps the plant focus on root growth. Do not trim the roots themselves.
Step 6: Plant At The Correct Depth
Place the rhizome in the hole with the bud facing upward. Cover with 2-4 inches of soil. In heavy clay, plant shallower—about 2 inches deep. In sandy soil, go deeper.
Water thoroughly after planting. The soil should be moist but not waterlogged. Add a layer of mulch to retain moisture and keep the roots cool.
Step 7: Water And Care After Transplanting
Keep the soil consistently moist for the first few weeks. Do not let it dry out completely. Once new shoots appear, reduce watering to once a week.
Fertilize with a balanced liquid feed (10-10-10) after new growth emerges. Avoid high-nitrogen fertilizers, which cause lush leaves but few flowers.
Transplanting Potted Calla Lilies
Potted calla lilies need repotting every year. They become root-bound quickly. Choose a pot that is 2 inches wider than the current one. Ensure it has drainage holes.
Remove the plant from its pot. Gently tease apart the roots. Trim any that are circling the bottom. Place the rhizome at the same depth it was before.
Use fresh potting mix with added perlite for drainage. Water well and place in bright, indirect light for a week. Then move to its permanent sunny spot.
Moving Potted Callas To The Garden
Harden off indoor plants before transplanting outdoors. Set them outside for a few hours each day over a week. This prevents sunburn and shock.
Dig a hole slightly larger than the root ball. Place the plant so the soil line matches the pot level. Backfill and water deeply.
Transplanting Calla Lilies In Cold Climates
If your winters drop below freezing, calla lilies will not survive outdoors. You must dig them up and store them. This is a form of transplanting that protects the rhizomes.
Wait until frost kills the foliage. Dig up the rhizomes and clean them. Let them dry in a warm, airy place for 3-5 days. Then store them in a box filled with peat moss or sawdust.
Keep the storage container in a cool, dark spot around 50°F (10°C). Check monthly for rot or shriveling. Mist lightly if they look wrinkled.
Replanting Stored Rhizomes In Spring
Start them indoors 6-8 weeks before the last frost. Plant each rhizome in a small pot with moist soil. Place in a sunny window or under grow lights.
Once the soil warms to at least 60°F (15°C), transplant them outdoors. Harden off first. This gives you a head start on the blooming season.
Common Mistakes To Avoid
Many gardeners fail at transplanting because they dig too early. If the leaves are still green, the plant is still feeding. Wait for yellowing.
Another mistake is planting too deep. Rhizomes buried more than 5 inches will rot. They need warmth to trigger flowering.
Overwatering after transplant is also deadly. Calla lilies like moisture, but they cannot handle standing water. Always check soil drainage before planting.
What To Do If Leaves Wilt After Transplanting
Some wilting is normal for the first week. Keep the soil moist and provide afternoon shade. Do not fertilize until new growth appears.
If the plant collapses completely, check the rhizome. It may have rotted. Dig it up, cut away damaged parts, and replant in drier soil.
When To Expect Blooms After Transplanting
Transplanted calla lilies usually bloom 8-10 weeks after planting. If you moved them in fall, they will bloom the following spring. Spring transplants may flower in mid-summer.
Divided rhizomes may skip a season if they are small. Large divisions with multiple buds will bloom on schedule. Be patient—the wait is worth it.
Frequently Asked Questions
Can I Transplant Calla Lilies While They Are Blooming?
It is possible but not recommended. Moving them during bloom will cause flowers to droop and die. Wait until the flowering period ends and foliage starts to yellow.
How Deep Should Calla Lily Rhizomes Be Planted?
Plant them 2-4 inches deep, depending on soil type. The top of the rhizome should be just below the soil surface. Deeper planting in sandy soil helps anchor them.
Do Calla Lilies Need To Be Dug Up Every Year?
Only in cold climates. In zones 8-10, they can stay in the ground year-round. Digging them up annually is optional but helps prevent overcrowding.
Why Are My Calla Lily Leaves Turning Yellow After Transplanting?
This is often transplant shock. Trim the yellow leaves and keep the soil moist. If the rhizome is healthy, new growth will appear within a few weeks.
Can I Transplant Calla Lilies In Summer?
Yes, but with extra care. Water deeply before digging, move them on a cool day, and provide shade for a week. They will recover, but may not bloom that season.
Final Tips For Success
Always sterilize your tools before dividing rhizomes. This prevents spreading disease. Use a 10% bleach solution or rubbing alcohol.
Label your transplants if you move multiple varieties. Calla lily colors can look similar when dormant. You will thank yourself next spring.
Mulch around the base of outdoor plants to regulate soil temperature. This also suppresses weeds that compete for nutrients.
If you live in a rainy area, consider planting calla lilies in raised beds. This improves drainage and prevents rhizome rot.
With proper timing and care, your calla lilies will settle into their new home quickly. They are forgiving plants that reward patience with spectacular blooms.
Now you know exactly how to transplant calla lilies. Gather your tools, pick the right day, and give your plants a fresh start. They will thank you with a riot of color and elegant, trumpet-shaped flowers.
Remember that the dormant season is your best friend. Working with the plant’s natural cycle makes the process easier for you and less stressful for them. Happy gardening.
