As the colder months approach, protecting your Canna lily rhizomes is essential to ensure healthy growth in the following season. Proper winter storage prevents rot and damage caused by freezing temperatures. Follow these steps to store your rhizomes effectively.
Preparing Canna Lily Rhizomes for Storage
Before storing, carefully dig up the rhizomes at the end of the growing season. Use a garden fork or spade to gently lift them from the soil, taking care not to damage the tubers. Shake off excess soil and inspect for any signs of disease or rot. Discard any compromised rhizomes.
Cleaning and Curing
Rinse the rhizomes with water to remove remaining soil. Allow them to dry in a warm, airy location for several days. This curing process helps to toughen the outer skin and reduces the risk of mold during storage.
Storing the Rhizomes
Choose a cool, dark, and dry place such as a cellar, basement, or garage. The ideal temperature is between 40°F and 50°F (4°C to 10°C). Keep the rhizomes in a breathable container like paper bags, mesh sacks, or cardboard boxes lined with peat moss, straw, or vermiculite to prevent moisture buildup.
Additional Tips for Storage
- Label each rhizome to identify varieties.
- Check periodically for signs of mold or rot and remove affected tubers.
- Avoid storing near fruits or vegetables that emit ethylene gas, which can accelerate spoilage.
- Maintain consistent storage conditions without fluctuations in temperature or humidity.
Resuming Growth in Spring
In early spring, when the danger of frost has passed, start preparing your rhizomes for planting. Soak them in water for a few hours to rehydrate, then cut back any damaged parts. Plant in well-draining soil and provide ample sunlight to encourage vigorous growth.
