How to Store Canna Lily Tubers Over Winter

As the growing season ends, many gardeners wonder how to protect their Canna lily tubers during the cold winter months. Proper storage ensures that these vibrant plants will thrive again in the spring. Follow these steps to store your Canna lily tubers safely over winter.

Preparing Canna Lily Tubers for Storage

Before storing, it’s essential to properly prepare your tubers to prevent rot and disease. Carefully dig up the tubers once the foliage has died back naturally or after a light frost. Gently brush off excess soil without damaging the tubers.

Inspect each tuber for signs of disease or damage. Discard any that show mold, soft spots, or other issues. Allow the healthy tubers to dry in a warm, well-ventilated area for a few days.

Cleaning and Curing

After drying, cut back the foliage to about 2 inches above the tuber. Some gardeners prefer to let the tubers cure for a week or two to toughen their skin, which helps prevent rot during storage.

Storing the Tubers

Choose a cool, dark, and dry location for storage. Ideal temperatures are between 40°F and 50°F (4°C to 10°C). Common storage spots include a basement, cellar, or unheated garage.

Place the tubers in a breathable container such as paper bags, mesh bins, or cardboard boxes. Avoid plastic bags, which can trap moisture and cause rot. Label each container for easy identification.

Adding Moisture Control

To prevent the tubers from drying out completely, add a layer of peat moss, sawdust, or sand around them. Check periodically during winter to ensure they remain firm and free of mold.

Tips for Successful Storage

  • Keep the storage area consistently cool and dark.
  • Inspect the tubers monthly for signs of rot or sprouting.
  • Remove any damaged or rotting tubers immediately.
  • Replant the tubers in spring after the danger of frost has passed.

With proper preparation and storage, your Canna lily tubers will be ready to bloom again each year, bringing vibrant color to your garden season after season.
