I'm just rummaging around the " garden questions" site Bill trying to put in my two cents worth giving answers. If you put a question mark anyplace on what you have said I'll give yours a try too:)...or should I keep the change since this might be a comment to the previous question by another member?

I put mine in sawdust in the garage so it is frost free. its lucky it survived over last winter outside.

Or you could use dry compost or sand. Just make sure its frost free and out of the way of mice.
