“After the first hard frost, cut back the blackened stems and gently lift the clump of roots with a spading fork. To prepare them for winter storage, label each clump with the variety name and stand the clumps upside down to drain away any moisture. After about a week of drying place them in a deep box and cover the clumps with slightly damp peat moss or wrap them in newspaper before storing. They are best stored in a place where the temperature is between 35-50 degrees. Be sure to examine the tubers for any rotting during the winter and remove decaying portions immediately.”
