Canna lilies, with their vibrant blooms and lush foliage, add a touch of tropical flair to any garden. However, when winter’s icy grip descends, these tender plants require special care to survive the cold months. In this comprehensive guide, we’ll delve into the secrets of how to store canna lily plants over winter, ensuring their safe return to the garden come spring.
Harvesting and Preparation
1. Lift the Plants:
Once the first frost has blackened the foliage, gently lift the canna lily plants from the ground using a garden fork. Shake off excess soil, being careful not to damage the rhizomes.
2. Remove Foliage:
Cut back all stems and leaves to about 6 inches above the rhizomes. This helps reduce moisture loss and prevents rot during storage.
3. Inspect the Rhizomes:
Examine the rhizomes thoroughly for any signs of damage or disease. Discard any that appear soft, mushy, or discolored.
Drying and Curing
4. Dry the Rhizomes:
Spread the rhizomes in a single layer in a warm, well-ventilated area. Allow them to air-dry for several days until they become slightly wrinkled but still firm.
5. Cure the Rhizomes:
Place the dried rhizomes in a shallow container filled with dry peat moss or vermiculite. This helps absorb excess moisture and prevents mold growth. Store the container in a cool, dark place (45-50°F) for 2-4 weeks.
Storage Options
6. Indoor Storage:
- Basement or Cellar: Store the cured rhizomes in a cool, dark basement or cellar where temperatures remain between 45-50°F. Place them in a box or bag filled with peat moss or vermiculite.
- Refrigerator: Wrap the rhizomes in a damp paper towel and place them in a plastic bag. Store in the refrigerator’s crisper drawer, where temperatures are typically around 40°F.
7. Outdoor Storage (Mild Climates):
In areas with mild winters, canna lilies can be stored outdoors.
- Mulch: Cover the rhizomes with a thick layer of mulch (6-8 inches) to insulate them from the cold.
- Trench: Dig a trench 12-18 inches deep and place the rhizomes inside. Cover them with soil and mulch.
Monitoring and Care
8. Check Regularly:
Throughout the winter, periodically check the stored rhizomes for any signs of rot or dehydration. Remove any damaged ones promptly.
9. Water Sparingly:
If the rhizomes appear dry, lightly water them with a spray bottle. Avoid overwatering, as this can lead to rot.
Replanting in Spring
10. Prepare the Rhizomes:
When the last frost has passed and soil temperatures have warmed, remove the rhizomes from storage. Gently break off any new growth and discard any soft or damaged areas.
11. Plant the Rhizomes:
Dig holes twice the width of the rhizomes and deep enough to cover them with 2-3 inches of soil. Plant them with the “eyes” (small buds) facing upwards.
12. Water and Fertilize:
Water the newly planted rhizomes deeply and fertilize them with a balanced fertilizer. Keep the soil moist but not waterlogged.
