How to Transplant Canna Lilies | 9 Simplified Steps (2025)

Canna lilies are striking, tropical-looking plants that add vibrant color and lush greenery to any garden. Transplanting these perennials is a simple process that ensures they thrive in optimal conditions, whether you’re moving them to a new spot or dividing them to encourage healthy growth.

By following a few key steps on how to transplant canna lilies, you can successfully transplant canna lilies and enjoy their stunning blooms year after year.

Understanding Canna Lilies and Their Growth Habits

Canna lilies are hardy perennials known for their eye-catching flowers and bold foliage. They thrive in warm, sunny climates and require fertile, well-draining soil to grow vigorously. While they are relatively low-maintenance, understanding their growth habits can help improve their overall health and appearance.

Canna lilies grow from rhizomes, which spread underground to produce new shoots each growing season. These plants can reach heights ranging from 2 to 8 feet, depending on the variety, and their vibrant blooms typically appear from summer through early fall. Regularly dividing their rhizomes not only keeps the plants healthy but also prevents overcrowding, ensuring your garden remains lush and thriving.

Reasons to Transplant Canna Lilies

Transplanting canna lilies is an essential step in maintaining their vigor and beauty. One of the primary reasons to transplant these plants is to prevent overcrowding, as their rhizomes spread quickly and can compete for nutrients and space. Overcrowded canna lilies may produce fewer blooms and exhibit stunted growth.

Transplanting also allows for rejuvenation of the soil, ensuring the plants receive adequate nutrients and drainage for optimal growth. Additionally, dividing and relocating canna lilies provides an opportunity to propagate new plants and expand their vibrant presence throughout the garden. Regularly transplanting canna lilies helps promote healthier plants and more abundant blooms.

Tools and Materials Needed

Garden Fork or Spade for Digging.
Clean, Sharp Knife or Pruners (for Division, if Needed).
Gloves to Protect Hands.
Compost or Organic Soil Amendment for Replanting.
Mulch to Retain Soil Moisture.

9 Step-by-Step Guidelines on How to Transplant Canna Lilies:

Step 1: Choose the Right Time

The best time to transplant canna lilies is in spring or early summer when new growth starts to appear.
Transplanting during this time allows the plants to establish themselves before the hot and dry weather of summer arrives.
If you live in a colder climate, it’s best to wait until the threat of frost has passed before transplanting.

Step 2: Prepare the New Site

Choose a new site that receives full sun and has well-draining soil.
Remove any weeds or debris from the area and loosen the soil with a garden fork.
Add compost or organic soil amendment to improve the nutrient content and texture of the soil.

Step 3: Dig Up the Canna Lily

Use a garden fork or spade to gently dig around the perimeter of the plant, being careful not to damage its roots.
Gradually lift the plant out of the ground, trying to keep as much of its root system intact as possible.
Shake off excess soil and trim any damaged or diseased roots with clean gardening shears.

Step 4: Divide the Rhizomes

Once the canna lily has been removed from the ground, carefully separate its rhizomes into smaller sections using your hands or a sharp knife.
Each section should have at least one healthy growing tip and a portion of its original root system.
Discard any old or unproductive rhizomes.

Step 5: Replant in Fresh Soil

Prepare a new planting hole for each divided section of the canna lily.
The hole should be at least 6 inches deep and wide enough to accommodate the rhizome comfortably.
Mix in some compost or well-aged manure into the soil for added nutrients.
Place the divided rhizomes into their respective holes, making sure that the growing tip is facing upward.

Step 6: Water and Mulch

Gently backfill each planting hole with soil, firming it around the rhizomes to eliminate any air pockets.
Water thoroughly to help settle the soil and provide moisture for the newly transplanted canna lilies.
Add a layer of mulch on top of the soil to help retain moisture, suppress weeds, and insulate the rhizomes during colder months.

Step 7: Monitoring and Care

Keep an eye on your transplanted canna lilies for the first few weeks to ensure they are adjusting well to their new location.
Water deeply once a week, or more frequently if there is a lack of rainfall. Avoid overwatering, as this can lead to root rot.
Fertilize with a balanced fertilizer every 4-6 weeks during the growing season to promote healthy growth and blooming.
Remove any dead or damaged foliage throughout the season.

Step 8: Overwintering

In areas with harsh winters, it is important to properly prepare and protect your canna plants for the cold months.
Before the first frost, cut back the foliage of your canna lilies and dig up the rhizomes.
Carefully clean off any excess soil from the rhizomes and let them dry in a cool, dark place for a few days.
Once dry, store them in a container filled with peat moss or vermiculite and keep in a cool, dry location such as a basement or garage.
Check on your stored rhizomes periodically throughout the winter to ensure they are not rotting or drying out.

Step 9: Dividing and Replanting

Canna lilies can become overcrowded over time, which can result in smaller flowers and less vigorous growth.
To prevent this, you can divide your canna lilies every 3-4 years.
Start by digging up the clump of rhizomes and gently separating them into individual sections.
Trim off any damaged or dead portions and replant the healthy sections into well-draining soil.
Water thoroughly after planting and continue with regular care as mentioned above.

Following these steps on how to transplant canna lilies will not only help maintain the health and appearance of your plants, but it will also give you the opportunity to expand your garden and share these beautiful flowers with others.

Additional Tips

If you live in a colder climate, consider growing canna lilies in containers so they can be brought indoors during the winter months.
To encourage blooming, fertilize your canna lilies with a balanced fertilizer every 2-3 weeks during the growing season.
Deadhead (remove) any faded or wilted flowers to encourage continuous blooming.
Divide and transplant canna lily rhizomes every 2-3 years to prevent overcrowding and maintain plant health.
When planting in containers, make sure they have good drainage and use a well-draining potting mix specifically designed for container gardening.
Water your canna lilies deeply at least once a week, more often during hot and dry weather.

By following these additional tips, you can ensure that your canna lilies will thrive and bring beauty to your garden year after year. Happy planting!

Aftercare for Transplanted Canna Lilies

Once you have successfully transplanted your canna lilies, proper aftercare is essential to help them establish and thrive. Begin by watering them thoroughly after planting to ensure the soil settles around the roots and eliminates any air pockets. Keep the soil consistently moist but not waterlogged during the first few weeks as the plants adjust to their new environment. Apply a balanced, slow-release fertilizer to encourage healthy growth and vibrant blooms.

Regularly remove any dead or yellowing leaves to maintain plant health and prevent disease. Additionally, keep an eye out for pests, such as spider mites or aphids, and treat them promptly if necessary. With attentive care, your transplanted canna lilies will reward you with lush foliage and striking flowers.

Special Considerations for Cold Climates

Canna lilies are tropical plants that thrive in warm environments, so special care is needed if you live in a region with cold winters. Before the first frost, dig up the rhizomes carefully to avoid damage. Trim the foliage to about two inches above the rhizomes and allow them to dry for a few days in a cool, shaded area. Once dried, store the rhizomes in peat moss or sand inside a breathable container, such as a cardboard box or mesh bag.

Keep them in a cool, dry location with temperatures between 40°F and 50°F. Check on them periodically to ensure they are not rotting or drying out completely. Come spring, you can replant the rhizomes once the soil has warmed, ensuring the continuation of your canna lily display year after year.
