5. Canna bulbs can be stored in a cool and dry location, ideally with a temperature between 45-50°F (7-10°C). It is important to monitor the bulbs during the storage period and discard any that show signs of decay or damage.
Storing Canna Bulbs In Colder Climates
Canna bulbs, with their vibrant tropical blooms, are not hardy in climates north of USDA hardiness zone 8. In colder climates, they must be treated as annuals or carefully dug up and stored for the winter to ensure their survival and optimal growth in the following season.
To store canna bulbs in colder climates, follow these steps:
-
Wait until after the foliage has died back but before the arrival of deep frost in the fall. This timing allows the plant’s energy to be fully redirected into the bulbs, providing a stronger foundation for storage.
-
Dig up the bulbs once they have reached this stage.
-
Replant the bulbs in the spring after the ground has thawed and the danger of frost has passed.
This method can also be applied to other tropical plants that grow from bulbs, tubers, corms, or rhizomes. By following these steps, you can ensure the proper care and longevity of your beloved tropical plants in colder climates.
- Wait until foliage dies back before digging up bulbs
- Replant in the spring after danger of frost is gone.

Steps For Digging And Storing Canna Bulbs
Digging up and storing canna bulbs is a simple process that requires a few steps to ensure success. To begin, wait until a frost has killed back the foliage before digging up the bulbs. This ensures that the plant’s energy is focused on the bulbs rather than the foliage.
Carefully dig around the bulbs, taking care not to damage them in the process. Canna bulbs are known to multiply rapidly over the summer, so dividing them may be necessary. If you notice overcrowding or clumping of the bulbs, gently separate them for optimal growth.
After the bulbs have been dug up and divided if necessary, cut the foliage back to 2-3 inches. This allows the bulbs to conserve energy and focus on their storage period. Next, gently wash the bulbs to remove any excess soil, but be cautious not to scrub them too vigorously. Scrubbing can cause scratches and potential rot, which can compromise the bulbs’ viability.
To further prevent rot, allow the bulbs to cure in a dry place for a few days. This process toughens the skin and prepares them for storage. Once cured, wrap the bulbs individually in newspaper or paper bags. This provides insulation and protection during their storage period.

Techniques For Storing Tropical Plant Bulbs
The technique for digging and storing canna bulbs can be applied to various other tropical plants that share similar growth patterns. Many tropical plants, including dahlias, begonias, and gladiolus, grow from bulbs, tubers, corms, or rhizomes and require similar care during storage.
When it comes to digging up these tropical plant bulbs, it’s important to follow the same steps outlined for canna bulbs. Here are the steps to follow:
- Wait for the appropriate time
- Dig carefully
- Divide if necessary
- Cut back foliage
- Wash gently
The curing process is also crucial for these plants to toughen their skin and prevent rot. Make sure to give them adequate time to cure before storing.
Storage should be done in cool, dry places such as the garage, basement, closet, or even the refrigerator. These locations provide a consistent temperature and protect the bulbs from excessive moisture.
Remember to check the bulbs monthly and remove any that show signs of rot, as they can quickly spread and damage the entire collection. Regular maintenance is important to ensure the longevity of your collection.
Tips For Curing And Wrapping Canna Bulbs
Curing canna bulbs is essential for storage as it strengthens their skin and prevents rot. To effectively cure the bulbs, follow these tips:
- After digging up the bulbs, allow them to dry in a well-ventilated area for a few days.
- During this time, the bulbs will naturally harden and develop a protective layer.
- Avoid placing the bulbs in direct sunlight, as this can cause them to dry out too quickly.
- Ensure that the area is dry, as excess moisture can lead to rotting.
- Once the bulbs have dried, they are ready to be wrapped and stored.
When it comes to wrapping canna bulbs, newspaper or paper bags are the preferred materials. Individually wrap each bulb to prevent them from touching and potentially transferring rot. Place them in a dark and cool location, ensuring they remain dry throughout the storage period.
Ideal Storage Locations For Canna Bulbs
Choosing the right storage location for canna bulbs is crucial for their long-term health and vitality. Ideal storage locations should offer:

Frequently Asked Questions
Should I cut the roots off canna bulbs before storing?
While some gardeners may choose to cut off the roots before storing canna bulbs, I find it beneficial to leave a stub and then remove the roots once I am ready to store them. By adopting this practice, the bulbs can retain some of their moisture and nutrients until they are ready to be lifted from the ground. Moreover, leaving the garden soil on the rhizomes until it dries out can help protect them and prevent any potential damage during the storage period. Ultimately, this approach ensures the bulbs’ optimum condition for future planting and growth.
What temperature kills canna bulbs?
Canna bulbs are fairly resilient, but extreme temperatures can be detrimental to their survival. The recommended temperature range for storing canna bulbs is between 40 and 50 degrees Fahrenheit, as this ensures they remain in optimal condition. However, it is important to note that temperatures below 40 degrees Fahrenheit can potentially cause harm to the bulbs and lead to their demise. Exposure to colder temperatures risks damaging their delicate tissues and affecting the viability of the bulbs. Therefore, it is essential to store canna bulbs in a cool, dry location above this threshold to protect their health and ensure their longevity.
When should I dig up my canna lily bulbs?
To ensure optimal growth for your canna lily bulbs, it is recommended to dig them up in the fall. Wait until the leaves have yellowed, died back, or have been affected by frost, but before the ground freezes completely. This timing allows for the longest growing season, enabling the plant to store sufficient food for the following year’s growth. To prepare the bulbs for storage, make sure to cut back any dead foliage to approximately 2 inches above the ground.
How do you store potted canna lilies?
To store potted canna lilies, those in colder areas can be relocated to a frost-free environment. In regions without severe winters, it is recommended to lift the rhizomes when the top growth starts to wither in autumn. Trim the foliage and stems to approximately 15cm (6in), eliminate excess soil, and place them in trays within barely-damp wood vermiculite or multi-purpose compost for storage.
