One should harvest sweet potatoes after the first frost has killed the plants or when day time temperatures have dropped into the 50s F. Dig the tubers with a pitch fork and if any get bruised, use those first because they will not store as well. Cure tubers by laying them out in the sun for a day followed by a warm (80 F) humid location out of direct sun for a couple of weeks. Finally store them in a dry, cool spot. They should store up to 5 -6 months.
