Bournemouthgardener Many thanks for your advice, as I said I don't have a greenhouse big enough to take the canna lilies, so your help sounds like the ideal solution to my dilemma .My husband did say I should treat them in a similar way to daffodils. I have been amazed by the help I have been given, I will get started on the lilies now since we have had a frost on a couple of nights.Many thanks.
