For successful storage, select high quality tubers.
Allow the crop to cure at 55 to 65 degrees Fahrenheit for
7 to 10 days. The storage area should be well-ventilated
and dark. Curing will be slower and incomplete at
temperatures less than 50 degrees Fahrenheit.
The storage area should have temperatures between 35 and
40 degrees Fahrenheit and moderately moist air. At
temperatures around 35 degrees Fahrenheit, potatoes may
turn sweet. This effect can be corrected by holding
potatoes at 70 degrees Fahrenheit for 1 to 2 weeks before
If the storage area is not dark, tubers may turn green and
bitter. DO NOT CONSUME SPROUTS, GREEN SKIN OR GREEN FLESH
