Cannas
Can you knowledgeable folk on this forum give me advice on what to do with my canna plant over winter . At present it is in a pot , and it did not flower this year , due I think to my late planting . I am unsure of the specific type of Canna it is , all I can recall is the height to which it would grow (75 cm ) . Do I treat it like a Dahlia and cut it back , dig it up and store it , or do I just leave to it's own devices and keep it frost free.
All advice will be much appreciated .

if you live somewhere mild , it's well drained and not overly rainy, you could leave them in the pot in situ. As it's in a pot, you might move it somewhere sheltered, porch, shed, garage, but not heated as they seem to like a sleep in winter.
So long as the compost doesn't freeze , or become waterlogged, it should be fine.
I have lots of these in the gaarden. I'm in the south but on heavy rich clay. Some years I leave them in the soil and most survive, but some rot away. So most years I lift them, put them in pots of leaf mould or compost, and keep them frost free, cool and quite dry until they shoot in spring.
if yours are in pots already I would just bring them into a frostfree greenhouse and leave them alone.
I do think they are hungry plants. When I plant them out in spring I always add a good handful of food. So perhaps in spring you should give them some feed to encourage more flowers?
But my cannas have just started flowering again, along with my dahlias. Should I still dig them up or can I enjoy them a little longer ?
