This past summer I purchased 3 bags of caladium bulbs for $1 each at Walmart. I put them in my garden and hoped for the best. They were spectacular! Now that Western New York is headed for the deep freeze, I am wondering how I can save the bulbs/corms/whatever for next year. I've already dug them out in case we get an early snow. Thanks for any help on what medium or container to keep them in.
