Planted my first Canna this year, and it's been spectacular. Was even flowering in early November!
Seeing as we're getting icy soon, should I cut it down now or wait for the frost?

Re: Canna protection
Thanks for that.
Suggests I can mulch if I've got 'well-drained sandy soil' ... LOL it's London clay thick enough to make pots with.
BUT, I also have Hedychium in the garden which survived last winter completely unprotected. So maybe.
Has anyone ever tried plastic roofing sheets just laid over top of soil as protection? Will keep snow off ... could it give a couple of extra degrees leeway?

Re: Canna protection
I would dig them up and store in a frost free shed or garage if I were you. I looked in earlier but your location says Madeira and I thought it would be a fair bit warmer there
As a side note I left both hedychium and canna out last year, hedychium came through canna died.

Re: Canna protection
Ah no, I'm in London at the moment. Soz for the confusion.
My little London garden is a frost trap, north-facing, full of slugs and snails and solid clay soil. I do my best with it!
The Canna's been brilliant this year, definitely going to plant more next year. Seems slug resistant, which is an essential requirement.

Cannas are less hardy than many Hedychiums and Dahlias.
Re: Canna protection
Welcome to the forum, Malmsey.
Cannas are so easy to lift and store. Starting them off again potted in a warm spot before planting them out will give you much better results than waiting for them to resprout from cold ground in the Spring.

Re: Canna protection
I don't have a warm spot to start them off in. Don't want them to take up the indoor space.
I've got 2 cannas, one is a Wyoming which is one of the hardiest supposedly, the other one is a Pretoria.
I'm going to leave the Wyoming in the ground, mulched with leaves, and to give it an early start in the spring I can put a bell cloche over it.
The Pretoria is in a pot, I've moved it to the blowaway GH and buried the pot in the ground, and I hope it survives there, if not the top then at least the rhizome or whatever it's called.
