The Best Way to Store Cannalily Bulbs: Tips and Techniques for Winter Survival

Canna lily bulbs are beloved for their vibrant colors and long blooming periods. Proper storage is crucial to ensure that these bulbs survive the winter and thrive in the spring. In this article, we will explore the best methods for storing canna lily bulbs, discuss the importance of proper storage conditions, and provide step-by-step instructions for keeping your bulbs alive and healthy through the colder months.

Why is Proper Storage Essential?

Canna lily bulbs are prone to fungal infections, which can quickly turn a thriving plant into a decaying mess. One effective method to prevent fungal growth is to coat the bulbs with a fungicide before storing them. Additionally, proper storage conditions are vital to keep the bulbs dormant and ready for growth once spring arrives.

The Best Storage Locations

The most ideal storage locations for canna lily bulbs are cool and dry areas, where the bulbs can remain dormant throughout the winter. Options include:

Garage: This area is often cool and dry, making it an excellent location for storing canna bulbs. However, ensure that the temperature remains consistently cold, ideally between 40-50°F (4-10°C). Basement: Similar to the garage, a basement with a consistent cool temperature can be ideal for storage. Check for any dampness and ensure good ventilation to prevent mold and mildew. Closet: A cool, dry closet that is away from any sources of heat can also be an effective storage spot. However, ensure that the bulb storage location is easily accessible for periodic checks. Refrigerator: For those with sufficient space, the crisper drawer of a refrigerator can provide a controlled environment for storing canna bulbs. Ensure that the temperature does not drop too low, as this can also damage the bulbs.

Storage Techniques

Once you have chosen the storage location, there are several techniques to ensure the bulbs remain healthy and dormant:

Coating with Fungicide

To prevent fungal infections, it is advisable to coat the canna lily bulbs with a fungicide before storing them. This step can significantly reduce the risk of rot and decay, ensuring the bulbs remain viable.

Wrapping in Paper and Placing in a Bucket

Another effective method is to wrap the bulbs in paper and place them in a 5-gallon bucket. Here’s how you can do it:

Dig Up the Bulbs: Carefully dig up the canna lily bulbs in late fall when the foliage has died back. Dry the Bulbs: Allow the bulbs to air dry in a shaded area to remove excess moisture, which can promote fungus growth. Create a Bed of Mulch and Paper: Place a layer of mulch at the bottom of the bucket, followed by a wad of wet newspaper or paper towels. Ensure that the paper is not overly wet, as this can lead to mold growth. Add the Bulbs: Place the canna lily bulbs on top of the mulch and paper, ensuring they are not overly cramped. Sprinkle more mulch on top and cover the bulbs with a layer of mulch. Protect from Freezing: Seal the bucket tightly to keep the crisper environment intact and place it in a cool, dry location.

Mesh Bag Storage

Some gardeners prefer to store canna lily bulbs in mesh bags. This method allows for good air circulation, which is crucial for the bulbs to remain dormant and healthy.

Prepare the Bulbs: Clean and dry the canna lily bulbs thoroughly. Insulate the Bulbs: Place the bulbs in a mesh bag, ensuring they are suspended freely to allow for air circulation. Store in a Cool Place: Hang the mesh bag in a cool, dark location to prevent premature sprouting and fungal growth.

Checking and Maintenance

It is important to check the stored bulbs periodically, ideally every month or so. During the winter, any bulbs that show signs of rot or decay should be removed to prevent the condition from spreading to other bulbs. This maintenance is crucial for maintaining a healthy stock of bulbs ready for planting in the spring.

By following these tips and techniques, you can ensure that your canna lily bulbs remain healthy and ready to grow come spring. Proper storage is the key to a successful flowering season and vibrant displays in your garden.
