I'd just like to ask for everyone's personal methods for overwintering cannas. I've read of several methods, RHS, Monty etc.
Im just looking for a method that has the highest success rate, preferably 100%!
Just bumping this up as I've hads no replies.
Last year I dug up my rhizomes and stuck them in pots (breaking bigger clumps to fit) and then left them in the shed. I lightly watered a couple of times over winter as I understand they shouldn't completely dry out.
I've had about 80% success in them coming back this year, which I read is about normal. This is my first winter growing/storing cannas.
Have to disagree about the dry conditions.
I follow Christo Lloyds method, pot up, keep frost free, and, keep just moist. He actually suggested watering every few weeks.
Sheffield versus Cornwall, might be a bit unfair, but I do have about 20 currently doing well, in my lounge. They were kept moist throughout winter.
Many different ways to skin a cat.
