When you count on a bountiful potato harvest, it is imperative that you store your seed potatoes carefully. Seed potatoes are the potatoes you will plant to grow new potato plants. Because these are actually small potatoes, you must store seed potatoes at the proper temperature and humidity levels to ensure they stay viable. With attention to these details, your seed potatoes will be ready to plant when the growing season begins.
Line the shallow bins with the hay, straw or shredded newspapers. This will cushion the seed potatoes and keep them from touching each other as they sit in the bins.
Place the seed potatoes into the bins carefully to minimize bruising. Check each potato as you place it in the bins and discard any potatoes you find with obvious bruising or decay. Make sure the potatoes do not touch each other in the bins.
Place the bins in a well-ventilated area with temperatures between 40 and 42 degrees F. Optimal humidity level for storing seed potatoes is between 85 and 90 percent.
Store the potatoes in this location for as many months as necessary. As long as the temperature and humidity level is constant, the potatoes will store well.
Move the bins to a slightly warmer location with fresh air approximately one week before you plan to plant them. Ideal temperatures for this location are between 50 and 55 degrees F. This will break the seed potato dormancy and prepare the potatoes for sprouting.
