Dividing canna lilies is a common gardening task that helps promote healthy growth and flowering. Proper storage after division ensures that your plants remain healthy and ready to replant in the next growing season. Following best practices can make this process more successful and stress-free.
Preparing Canna Lily Divisions for Storage
Before storing, carefully dig up the divided canna lilies and remove excess soil. Inspect the rhizomes for any signs of disease or damage. Healthy rhizomes are firm, plump, and free of mold or rot.
Cleaning and Trimming
Use a clean, sharp knife or garden shears to trim away any damaged or diseased parts. Remove dead or yellowing foliage to reduce moisture retention and prevent rot during storage. Allow the trimmed rhizomes to air dry for a few hours to form a protective callus.
Drying the Rhizomes
Place the rhizomes in a well-ventilated, shaded area for about 1-2 weeks. Proper drying helps prevent mold and rot during storage. Avoid direct sunlight, which can cause the rhizomes to dry out excessively.
Storage Conditions
Store the dried rhizomes in a cool, dark, and dry location. Temperatures between 40-50°F (4-10°C) are ideal. Use mesh bags, paper bags, or cardboard boxes with ventilation holes to allow air circulation. Avoid plastic containers, which can trap moisture and promote mold growth.
Monitoring and Maintenance
Check stored rhizomes periodically for signs of mold or shriveling. Remove any that show signs of deterioration to prevent affecting others. Maintaining proper humidity and temperature is key to successful storage.
Replanting Tips
When spring arrives, gradually reintroduce the rhizomes to warmer temperatures and begin watering. Plant them in well-draining soil with the crown just below the surface. Properly stored rhizomes will sprout and flourish in the growing season.
Summary of Best Practices
- Carefully clean and trim rhizomes before storage.
- Allow rhizomes to dry in a shaded, ventilated area.
- Store in a cool, dark, dry location with good air circulation.
- Regularly inspect stored rhizomes for signs of deterioration.
- Replant in spring after gradual temperature acclimation.
