Calla lilies are elegant plants that can add a touch of sophistication to any garden or indoor space. However, in colder climates, they require special care during the winter months to ensure they survive and thrive for years to come. One of the most important aspects of wintering calla lilies is choosing the right containers for storage and protection.
Why Choosing the Right Container Matters
The container you select can influence the health of your calla lilies during winter. Proper containers protect the rhizomes from extreme cold, prevent excess moisture buildup, and facilitate easy handling. The right container also ensures proper drainage and aeration, which are essential for preventing rot and disease.
Types of Containers Suitable for Wintering Calla Lilies
- Plastic Containers: Lightweight and resistant to moisture, plastic containers are easy to handle. Ensure they have drainage holes.
- Ceramic or Clay Pots: These provide good insulation but can be heavier and prone to cracking in freezing temperatures. Use with proper drainage.
- Wooden Boxes: Natural and breathable, wooden containers help prevent excess moisture but need to be well-ventilated.
- Storage Bins: Large plastic or wooden bins with secure lids are ideal for storing rhizomes in a cool, dry place.
Factors to Consider When Selecting Containers
When choosing a container for wintering calla lilies, consider the following:
- Drainage: Ensure the container has drainage holes to prevent water accumulation.
- Size: The container should be large enough to hold the rhizomes comfortably with some space for growth.
- Material: Opt for materials that insulate well and withstand cold temperatures.
- Weight: Heavier containers are more stable but harder to move; balance your needs accordingly.
Preparing Containers for Winter Storage
Before placing calla lily rhizomes into containers for winter, prepare them properly:
- Clean containers thoroughly to prevent disease.
- Ensure drainage holes are unobstructed.
- Use a well-draining soil mix or add gravel at the bottom for extra drainage.
- Allow the rhizomes to dry slightly before storing to prevent rot.
Storing Calla Lilies During Winter
Once in containers, store the calla lilies in a cool, dark, and dry location. Ideal storage temperatures range from 35°F to 50°F (1.5°C to 10°C). Check periodically for signs of mold or rot and remove any compromised rhizomes immediately.
Conclusion
Choosing the right container is crucial for successfully wintering calla lilies. Consider the material, size, and drainage capabilities of your containers to provide optimal protection during the cold months. Proper preparation and storage will help ensure your calla lilies return healthy and vibrant in the spring.
