Calla lilies can be divided and transplanted successfully to refresh your garden and create new plants.
Dividing and transplanting calla lilies involves carefully separating the rhizomes and replanting them in suitable soil conditions.
If you want your calla lilies to thrive and multiply, knowing how to divide and transplant calla lilies the right way is essential.
In this post, we’ll walk through how to divide and transplant calla lilies, the best times to do it, and tips to ensure they flourish after transplanting.
Let’s dive into how to divide and transplant calla lilies with confidence.
Why And When To Divide And Transplant Calla Lilies
Dividing and transplanting calla lilies is a great gardening practice because it helps rejuvenate older plants and encourages more blooms.
Knowing when and why to divide and transplant calla lilies ensures your plants stay healthy and vibrant.
1. Overcrowding of Rhizomes
As calla lilies grow, their underground rhizomes multiply and can quickly become crowded.
When rhizomes overcrowd, the plant struggles to absorb enough nutrients and water, resulting in fewer flowers.
Dividing calla lilies solves this by giving each rhizome enough space to grow.
2. Best Time To Divide And Transplant Calla Lilies
The best time to divide and transplant calla lilies is in early spring before new growth starts or in the fall once flowering has ended.
Dividing during dormancy reduces transplant shock and helps the plant establish quickly after replanting.
Avoid attempting to divide while plants are actively flowering or stressed by hot summer weather.
3. To Propagate And Get More Plants
If you want to increase the number of your calla lilies, dividing the rhizomes is the most effective method.
You can transplant the divisions into new spots in your garden or share them with friends to multiply your collection easily.
4. To Maintain Healthy Plants
Dividing calla lilies also removes old, diseased, or damaged rhizomes, contributing to overall plant health.
Regular division every few years keeps your calla lilies thriving and looking their best.
Step-By-Step Guide On How To Divide And Transplant Calla Lilies
Understanding how to divide and transplant calla lilies properly is key to garden success.
Follow these steps carefully to safely divide your calla lilies and ensure they grow successfully in their new location.
1. Prepare Your Tools And New Planting Site
Before digging up your calla lilies, prepare clean, sharp garden tools like a spade, pruning shears, and gloves.
Also, choose a new planting area with well-draining soil and partial to full sun exposure for transplanting the divisions.
Loosen the soil in the new area and enrich it with compost to give your calla lilies a great start.
2. Carefully Dig Up The Plant
Gently dig around the base of the calla lily clump to lift it from the ground without damaging the rhizomes or roots.
Use a spade to lift the entire clump out, shaking off excess soil to expose the rhizomes.
3. Separate The Rhizomes
Look for natural divisions in the rhizomes — generally, each division should have at least one healthy growing eye or bud.
Using your hands or a clean knife, carefully cut or pull the rhizomes apart.
Discard any shriveled, rotten, or damaged sections to avoid spreading disease.
4. Trim Dead Leaves And Roots
Once separated, trim any dead or unhealthy leaves and roots from each division.
This helps the plant focus energy on new root growth in their new location.
5. Plant The Divisions Properly
Plant each division in the prepared soil at a depth allowing the rhizome buds to point upwards.
Space divisions 12 to 18 inches apart to give them enough room to grow.
Water them well after planting to settle the soil around the roots.
6. Mulch And Care
Add a layer of mulch around the newly transplanted calla lilies to retain moisture and regulate soil temperature.
Keep the soil consistently moist but not waterlogged during their initial growth period.
Tips And Troubleshooting For Successful Calla Lily Dividing And Transplanting
Even when you know how to divide and transplant calla lilies, small mistakes can affect their success.
These tips will help you avoid common pitfalls and keep your calla lilies flourishing for years.
1. Don’t Divide Too Frequently
While dividing calla lilies is good, overdoing it can stress the plants.
Only divide every 2-3 years or when they become overcrowded or unhealthy.
2. Avoid Drying Out The Rhizomes
After dividing, don’t let the rhizomes dry out before planting as this can damage their growth buds.
Keep them moist and plant within a day if possible.
3. Provide Adequate Watering After Transplanting
Calla lilies need regular watering after transplanting to develop strong roots.
Monitor soil moisture and water any time the top inch feels dry.
4. Protect From Extreme Weather
Avoid transplanting calla lilies during extreme heat or cold.
If a late frost or summer heatwave is forecast, provide some protection like frost cloth or shade temporarily.
5. Fertilize After Transplanting
Feed calla lilies with a balanced fertilizer a few weeks after transplanting to encourage healthy growth and blooms.
Use a fertilizer rich in phosphorus to support root development.
So, How To Divide And Transplant Calla Lilies?
Dividing and transplanting calla lilies is a straightforward garden task that rejuvenates your plants and helps you grow more.
You divide calla lilies by digging up the clump carefully, separating healthy rhizomes with buds, and replanting them in well-prepared soil.
The best time to divide and transplant calla lilies is during their dormant period—in early spring before new growth or in the fall after blooming finishes.
Providing proper care like watering, mulching, and fertilizing post-transplant ensures that dividing calla lilies leads to flourishing, vibrant plants.
Whether you’re refreshing overcrowded beds or propagating to expand your garden, knowing how to divide and transplant calla lilies is an essential skill all calla lily lovers should master.
Enjoy the process, and watch your calla lilies multiply and brighten your garden year after year.
