Do not leave in ground exposed to high soil temperatures from sun because this will accelerate over-ripening. Wash potatoes and remove those diseased or damaged. Avoid exposing tubers to light. They will turn green with even small amounts of light. Store in as cool a place as possible.
Cool basements are probably the best storage available.
Keep humidity high and provide good ventilation. Wash roots, trim both tap root and tops, store in plastic bags in refrigerator for up to one month. Winter or black radishes are stored the same as carrots. Turnips can be harvested from the time they are one inch in diameter. They are best as a fall crop and can withstand several light freezes.
