The tank for storage must also be properly ventilated.

The easiest thing that one can do is to place the root crops into a perforated paper bag or a carton box with some small holes for ventilation. Choose the coolest area in the kitchen or store them in a dry part of the basement if you live in a house.

Refrigerator, unlike the widespread belief, is a bit too cool for potatoes which will make them become brown faster than they should be.

And never store potatoes in plastic packets since they don’t have enough air and the root crops will spoil very soon.

How to tell if a potato is bad?

Actually, one doesn’t have to be an experienced farmer to see the difference between the fresh and slightly or too spoiled root crops.

  • When potatoes have gone bad, you will see the growths on the surface of the root crops
  • Discoloration can also take place
  • Spoiled root crops become much softer and wither
  • Mold is another sign of spoilage


Some think that green sprouts are also the symptom of spoilage but it is not true. Since potato is alive after picking, it continues growing and, if we expose it to direct light for quite a long period of time, the sprouts will appear. Just cut them off and use the root crops as usual.
