[4season]

Just harvest before frost.
A quote from MOGFA ( Maine organic farmers assn )
Harvested sweet potatoes should be cured with adequate ventilation at 80 to 90 F. and at 85 to 90% relative humidity for five to 10 days to heals wounds on their skin, suberize the skin and increase storage life. Grube cured her sweet potatoes for zero, four and eight days in an empty, unheated greenhouse, watering the gravel floor to provide humidity. The day temperature was 85; night, 60. Roots cured for longer than eight days would lose excess moisture. We just put ours in the back room.
