How to store sweet potatoes

Do not wash the potatoes with water when you bring them home. If the potatoes have soil on the outside and the soil is wet, you should let the potatoes dry for a day before storing them.

Note that if you sunbathe the potatoes, you should not sunbathe them for too long. Just sunbathe until the outer soil layer is dry. Sunbathing for too long will cause the potatoes to wither and lose moisture.

Prepare a wooden box with partitions.

Line a layer of newspaper at the bottom of the box. Then, take a tissue paper, put baking soda inside, and wrap it tightly. Put the baking soda packet into the box and arrange the sweet potatoes on top. Do not pour all the potatoes into the box at once, but stack them neatly one by one. After each layer of potatoes, lay a layer of newspaper and add a baking soda packet. Do this until all the purchased potatoes are used up.
