Begin digging 90 to 120 days after planting. Plant tops die as tubers reach maturity. Allowing the potatoes to remainin the ground a few days after tops die or after tops are cut will help set or toughen the skin and reduce skinning, bruising and rots in storage.

Spraying potatoes with a general purpose fungicide (daconil or maneb) at the end of April or early May will protect the foliage from early blight and improve yields.

To keep potatoes for several weeks, allow cuts and skinned places to heal over at high temperatures, then store in a cool, dark place with high humidity. Don't store where they will receive light, since they will turn green and develop an undesirable taste.
