Calla lilies are elegant and popular flowers that require proper care even after they have been deadheaded early in the season. Proper storage can help ensure healthy growth and vibrant blooms in the following season.
Understanding Calla Lily Growth Cycles
Calla lilies (Zantedeschia spp.) grow from rhizomes, which store nutrients and energy necessary for new growth. Deadheading removes spent flowers, encouraging more blooms, but the rhizomes need proper care during the off-season to remain healthy.
When to Store Calla Lilies
The ideal time to store calla lily rhizomes is after the foliage has naturally died back in late fall or early winter. This period allows the plant to enter dormancy, making storage safer and more effective.
Steps for Proper Storage
- Cut back the foliage: Once the leaves turn yellow and die back, cut the stems close to the rhizome.
- Dig up the rhizomes: Carefully dig around the plant to avoid damaging the rhizomes. Use a garden fork or spade.
- Clean the rhizomes: Brush off excess soil and rinse with water if necessary. Allow them to dry in a warm, dry place for a few days.
- Inspect for damage: Discard any rhizomes that are soft, moldy, or damaged.
- Store in a suitable medium: Place healthy rhizomes in a paper bag or mesh container filled with peat moss, sawdust, or vermiculite to prevent moisture buildup.
- Maintain the right environment: Store in a cool, dark place with temperatures around 50-60°F (10-15°C). Avoid freezing temperatures.
Tips for Successful Storage and Replanting
Proper storage ensures that calla lilies will bloom again next season. Check stored rhizomes periodically for signs of rot or mold. Before planting in spring, soak the rhizomes in water for a few hours to promote sprouting.
Replanting Calla Lilies
When the danger of frost has passed, replant the rhizomes in well-draining soil. Space them about 12 inches apart and plant them at a depth of 2-3 inches. Water thoroughly and provide plenty of sunlight to encourage healthy growth.
Conclusion
Storing calla lilies after early season deadheading is a simple process that can extend the life and beauty of these stunning flowers. Proper handling and storage of the rhizomes will help ensure vibrant blooms year after year.
