Calla lilies are beautiful and elegant plants that can be enjoyed year after year when stored properly during the off-season. Proper storage of calla lily tubers is essential to ensure their longevity and vigorous growth in the next planting season. This article outlines the best practices for storing calla lily tubers effectively.
Understanding Calla Lily Tubers
Calla lilies grow from tubers, which are underground storage organs that contain nutrients for the plant. After the flowering season, these tubers enter a dormant state. Proper handling during dormancy is crucial to maintaining healthy tubers for future planting.
Preparing Tubers for Storage
Before storing, carefully dig up the tubers once the foliage has yellowed and died back. Gently brush off excess soil without damaging the tubers. It’s important to inspect each tuber for signs of disease or damage and discard any that appear unhealthy.
Cleaning and Curing
After removal from the soil, allow the tubers to dry in a warm, well-ventilated area for several days. This curing process helps to toughen the skin and reduces the risk of rot during storage. Do not wash the tubers with water, as excess moisture can promote decay.
Optimal Storage Conditions
- Temperature: Store tubers at 40-50°F (4-10°C).
- Humidity: Maintain low humidity levels, around 50-60%.
- Light: Keep tubers in a dark place to prevent sprouting.
- Ventilation: Ensure good air circulation to prevent mold and rot.
Storage Methods
Several storage options are suitable for calla lily tubers:
- Paper Bags: Place tubers in paper bags with some ventilation holes.
- Cardboard Boxes: Use boxes lined with dry peat moss or vermiculite.
- Mesh Baskets: Allow for excellent airflow and easy inspection.
Monitoring and Maintenance
Periodically check stored tubers for signs of mold, rot, or sprouting. Remove any damaged or sprouted tubers to prevent the spread of disease. Maintaining proper conditions ensures healthy tubers ready for planting in the spring.
Replanting Tips
When the danger of frost has passed, replant the tubers in well-drained soil. Space them about 12 inches apart and plant them at a depth of 3-4 inches. Water thoroughly and provide adequate sunlight for optimal growth.
Conclusion
Proper storage of calla lily tubers is vital for maintaining their health and ensuring vibrant blooms each year. By following these best practices—cleaning, curing, storing in suitable conditions, and monitoring—you can enjoy beautiful calla lilies season after season.
