I have a Cannova Yellow Canna Lilly. The cold hardiness says 20 to 10 degrees Farinheit. I have it in the ground. If I mulch and cover with a bucket can I save it through the winter? What are your suggestions for it’s survival?
If you live here in the Albany area (USDA hardiness zone 5) there is no amount of mulch or covering that will keep them alive over winter…they must be dug up and stored in a cool place inside. HERE’S A LINK to a tutorial on how to do it.
