Overwintering Cannas - Peat Moss?
this is my first winter with cannas. once i dry out the rhizomes in the sun and transfer them into a box inside a dry space like a garage, do i need to cover the rhizomes with anything like peat moss to keep them warm? or just throw them into an empty cardboard box? i guess this question applies for any bulbs that require overwintering such as elephant ears, etc.
thanks so much!
