How do I cure sweet potatoes for long term storage?

What is the best way to successfully store freshly dug sweet potatoes for the winter? The sweet potatoes I buy at the store don't last long at all.

The optimal conditions for sweet potato storage is 40-45 degrees at 90% humidity. However, if you are digging yours up you need to condition them first. This involves setting them out so they don't touch each other in a cool dry place for two weeks. Keep them out of strong light. This allows the outer tissue to convert from sugars to starch, which is the storage form. The biggest cause of storage failure in tubers is too warm of temperature. If properly stored they should be good for 2 to 9 months.
