My Cannas Dried Out Over Winter. Why?
I dug up all my cannas (like I usually do) after the first frost dropped the foliage in October in Wisconsin and stored them in the basement over the winter. I put them in white garbage bags filled with peat moss and did not tie them shut. Well, last week I looked inside the garbage bags and almost all of the cannas shriveled/dried up. There's hardly anything left to them...no tubers. Any suggestion as to why this happened since it's never happened before in the 3 years that I've been planting cannas? Thanks for any suggestions!
