Harvest when the tops have yellowed or died. Do not leave in the ground exposed to high soil temperatures from sun because this will accelerate over-ripening. Wash potatoes and remove any that are diseased or damaged. Avoid exposing tubers to light. They will turn green with even small amounts of light.
Cool basements are probably the best storage available.
Keep humidity high and provide good ventilation. Storage time is 2 to 4 months. Ideal storage is 32 to 40 degrees F and 90 to 95 percent humidity. Harvest pumpkins and winter squash when skin is hard and the colors darken. Both should be harvested before frost.
