Canna lilies are vibrant and exotic plants that bring a tropical touch to gardens and landscapes. While they are typically grown as summer-blooming perennials in warmer climates, gardeners in cooler regions can enjoy their beauty year-round by following proper storage and care techniques. This guide provides essential tips on how to store canna lily tubers during the off-season, ensuring they remain healthy and ready to bloom each year.
Understanding Canna Lilies and Their Storage Needs
Canna lilies are tuberous plants native to tropical regions. Their tubers store energy and nutrients, allowing them to regrow each season. In areas with cold winters, these tubers are susceptible to frost damage. Proper storage involves protecting them from cold temperatures, moisture, and pests. With the right techniques, you can extend their life and enjoy their stunning flowers year after year.
Preparing Canna Lilies for Storage
Before storing your canna lily tubers, follow these steps:
- Wait until the foliage has completely died back after the first frost.
- Carefully dig up the tubers using a garden fork or spade, taking care not to damage them.
- Gently shake off excess soil and rinse the tubers with water if needed.
- Allow the tubers to dry in a warm, well-ventilated area for several days.
Proper Storage Techniques
Once dried, store the tubers in a suitable container. Here are some recommended methods:
- Place tubers in paper bags or mesh baskets to allow air circulation.
- Fill containers with dry materials such as peat moss, vermiculite, or sawdust to prevent moisture buildup.
- Store in a cool, dark place with temperatures between 40°F and 50°F (4°C to 10°C).
- Avoid storing near fruits or vegetables that emit ethylene gas, which can harm the tubers.
Monitoring and Maintenance During Storage
Regularly check the stored tubers for signs of rot, mold, or pests. Discard any damaged tubers to prevent the spread of disease. Ensure the storage environment remains dry and cool. If the tubers start to sprout, you can choose to plant them indoors or in a greenhouse to extend their growth cycle.
Replanting Tips for a Bountiful Bloom
When the danger of frost has passed in spring, replant your canna lily tubers outdoors. Follow these tips for successful replanting:
- Choose a sunny location with well-draining soil.
- Plant tubers 4 to 6 inches deep, spacing them about 12 inches apart.
- Water thoroughly after planting and maintain consistent moisture.
- Apply a balanced fertilizer to promote healthy growth and vibrant blooms.
With proper storage and care, your canna lilies can be enjoyed year after year, transforming your garden into a tropical paradise regardless of your climate.
