The beautiful are not hardy
There are types of canna like Canna Lumbautum - a visually less appealing and not very common species - that can tolerate freezing temperatures. But the species and varieties common in trade are not winter hardy. For this reason, if you want to admire it again in the following year, you must protect your canna from frost.

Where can canna be overwintered?
Since this tropical plant is extremely sensitive to ice and snow, it should be provided with a shelter in winter. Hibernating canna outdoors is pointless.
Canna could only be wintered outside in mild winter locations and provided with appropriate protection. That is why it is advisable to find quarters at home, in the basement or in the garage.
What's the best way to overwinter Canna?
The entire plant, including stems and leaves, can only be overwintered in a winter garden. If you don't have a winter garden, you should only overwinter the rhizomes.
Proceed as follows with the tubers:
- excavate in late autumn
- free from the rest of the earth
- put in sand, sawdust or earth and cover with the respective material
- overwinter in a cool place (temperatures between 5 and 10 ° C)
- if necessary, pour lightly from time to time
When is it time to leave the winter quarters?
The wintering of the rhizomes can come to an end as early as January. Then the rhizomes can be driven forward. Whether driven or not driven, Canna should not be planted outdoors until May. From March it can be placed in the pot on the balcony or terrace during the day and on frost-free days.
Tips & Tricks
Don't worry if the Canna was transported to her quarters too late in autumn and had to see a frosty night. As a rule, the plant survives brief exposure to frost.
