You will need to bring them indoors for the winter. After a light frost kills the foliage, cut it back and gently dig it up. Wash it off and let it air dry in a warm place for several days. Then store in clean shavings or vermiculite or similar material in a paper bag or cardboard box in a dry cool place, about 50 degrees or so. Check periodically for rotting (too cold or too damp) or shriveling (to warm) and modify the storage accordingly. Good luck! |
