Planting Cannas
The cannas, which grow up to 1.5 meters tall, love a full sun and absolutely sheltered from the wind. You can plant the flowers there from the middle/end of May. Please note, however, that you must keep a sufficient distance to other plants when planting, because a canna shrub is between 60 and 100 centimeters wide.
You can also plant cannas in pots of appropriate size. However, these should definitely have a water drain. The cannas usually grow just as well in containers. Another advantage of growing in containers is that you only have to store your cannas in winter. So there is no digging here.

» Overwintering:
Cannas cannot withstand our freezing temperatures, which is why you have to overwinter the flowers in a cool, frost-free and completely dark room (if necessary, wrap them in an opaque jute sack).
For overwintering the canna, you should place the rhizome in a pot with potting soil and keep it as dry as possible - however, it must not dry out completely, which is why you should moisten it a little with a water sprayer from time to time.
