If your canna lilies are getting crowded or you simply want to move them to a sunnier spot, knowing how to transplant canna lilies is a key skill. This simple step-by-step guide will walk you through the entire process, from digging them up to settling them into their new home.
Transplanting cannas helps them thrive by giving their roots more space and refreshing the soil. Whether you’re dividing a large clump or moving the whole plant, the steps are straightforward. With the right timing and a little care, your cannas will bounce back quickly and reward you with vibrant growth.
How to Transplant Canna Lilies
This main section covers the complete transplant process. We’ll break it down into clear phases so you know exactly what to do and when to do it.
When is the Best Time to Transplant Cannas?
Timing is everything for a successful move. The ideal moment depends on your climate and goals.
For most gardeners, the absolute best time is in the spring, just as new growth begins to emerge from the soil. The plants are full of energy and the cool, moist spring weather helps them establish roots quickly.
You can also transplant in early fall, at least 6-8 weeks before your first expected frost. This gives the roots enough time to settle in before winter dormancy. Avoid transplanting in the peak summer heat, as the stress can be to much for the plant.
If you are moving potted cannas you just bought, you can do that anytime during the growing season. Just be sure to water them well before and after.
What You’ll Need to Get Started
Gathering your tools beforehand makes the job smoother. Here’s a basic list:
- A sharp spade or garden fork
- Pruning shears or a sharp knife
- A garden hose or watering can
- Wheelbarrow or tarp for moving divisions
- Compost or well-rotted manure
- Fresh garden soil or potting mix (if potting)
- Optional: A slow-release fertilizer
Step-by-Step Transplanting Instructions
Follow these numbered steps for the best results. Work on a cloudy day or in the evening to prevent the exposed roots from drying out.
Step 1: Prepare the New Planting Site
Always dig the new hole first. This minimizes the time the plant’s roots are out of the ground.
The new hole should be about twice as wide as the expected root ball and just as deep. Mix some compost into the soil you removed to improve drainage and add nutrients. This gives the canna a great head start.
Step 2: Dig Up the Canna Lily Clump
Start by watering the canna clump thoroughly the day before. This hydrates the plant and makes the soil easier to work with.
Use your spade to dig a wide circle around the plant, about 8-12 inches from the base. Push the spade deep to get under the root system. Gently lever the entire clump out of the ground and lift it onto your tarp.
Step 3: Divide the Rhizomes (If Needed)
This is the perfect time to divide overcrowded cannas. Shake or hose off excess soil so you can see the rhizomes clearly.
Look for the fat, healthy rhizomes with at least 2-3 “eyes” (those pinkish growth buds). Cut them apart with your clean shears or knife. Discard any sections that look rotten, mushy, or have no eyes.
Let the cut surfaces air-dry for a few hours before replanting. This helps prevent rot. Some gardeners also dust the cuts with sulfur powder for extra protection.
Step 4: Plant at the Right Depth
Place the canna rhizome or entire clump in the prepared hole. The key is to plant it at the correct depth.
The rhizome should be buried about 4-5 inches deep. The eyes should be facing upwards. If you are planting a clump with existing foliage, set it so the base of the stems is at the same level it was growing before.
Step 5: Backfill and Water Deeply
Fill in the hole with your improved soil mix, gently firming it around the roots to eliminate large air pockets.
Create a shallow basin around the plant to hold water. Then, give it a long, deep drink. This settles the soil and ensures moisture reaches the root zone. Add more soil if it settles to much after watering.
Aftercare for Your Transplanted Cannas
Your job isn’t quite done after planting. Proper aftercare ensures a strong recovery.
Water regularly to keep the soil consistently moist (but not soggy) for the first 4-6 weeks. A layer of mulch around the base helps retain moisture and suppress weeds.
If you didn’t add compost, you can apply a balanced fertilizer about a month after transplanting. Hold off on heavy feeding until you see strong new growth.
If any leaves wilt or turn yellow, simply trim them off. The plant is directing its energy to its roots. New, healthy leaves will soon follow.
Common Problems and Solutions
Sometimes, things don’t go perfectly. Here’s how to handle common issues.
- Slow Growth: This is normal right after transplanting. Be patient. Ensure the plant gets enough sun and water.
- Leaf Scorch or Wilting: This is often transplant shock. Provide shade for a few days with a cloth or screen and keep up with watering.
- Rotting Rhizome: Usually caused by planting to deep or in poorly draining, soggy soil. You may need to dig it up, cut away rot, and replant in a better location.
FAQ About Transplanting Canna Lilies
Can you transplant canna lilies in the summer?
It’s not ideal. The heat stresses the plant. If you must, do it on a cool, cloudy day, water extremly well, and provide temporary shade.
How often should you divide and transplant cannas?
Every 3-4 years is a good rule. You’ll know it’s time when the center of the clump looks dead and flower production decreases.
How deep do you plant canna lily rhizomes?
Plant them 4 to 5 inches deep. In colder zones, some gardeners go 6 inches for extra winter protection.
Can I grow transplanted cannas in pots?
Absolutely. Choose a large pot with drainage holes. Use a quality potting mix and water more frequently, as containers dry out faster.
Why are my transplanted cannas not flowering?
They may be putting energy into root growth first. Ensure they get at least 6 hours of sun and have adequate nutrients. Too much nitrogen can also lead to leaves but no flowers.
Transplanting canna lilies is a simple way to multiply your plants and keep them healthy. By following this guide, you give them the best chance to adapt and flourish in there new location. Remember, the main steps are careful digging, proper division, and consistent aftercare. With a little effort, you’ll enjoy these tropical beauties for many seasons to come.
