Potato storage will be more successful if only good quality tubers are stored. Allow the crop to cure at 55 to 65 degrees for 7 to 10 days. The storage area should be well-ventilated and dark. The process will be slower and incomplete at temperatures less than 50 degrees.
The storage area should have temperatures between 35 and 40 degrees and moderately moist air. At temperatures around 35 degrees the potatoes may turn sweet. This can be corrected by holding them at 70 degrees for 1 to 2 weeks before using them.
If the storage area is not dark, the tubers may turn green and bitter.
