Answer: IN the fall once frost has killed the tops, cut them off. Then gently dig up the rhizomes. Wash them off and dry them for several days in a warm place. Then store in shavings, spagnum peat moss or vermiculite or similar material in a paper bag or cardboard box. Do not let the rhizomes touch each other. They should be kept in cool dry place with a temperature of about 50 degrees. Check them periodically to make sure they are not rotting (too cold or too wet) or shriveling (too warm) and make any needed adjustments. Discard any that begin to rot so they do not infect the others. In spring plant them out when you set out tomatoes, or pot them up ahead of time for a head start. Good luck!
