I've split and saved dahlia tubers and wintered them in brown bags in sawdust. When I looked at them today, they seemed dried and I'm afraid they're dead. How can I tell if they lived through the winter on the sunporch? Thanks.

If the survived, they will feel firm but not stiff on the inside if you squeeze it, similar to a potato in your pantry that is a bit past its prime. If it is dry and stiff or mushy, it is likely dead.
