Wait for the sweet potatoes to reach the desired size, which usually occurs three or four months after planting.
Use a spade fork to dig into the soil up to 6 inches where the potatoes are. Be careful not to nick the potatoes during this process, as they bruise easily.
Brush off any excess dirt from the potatoes. Avoid washing them unless you are eating them immediately.
Place the potatoes in a location with humidity at 90 percent and the temperature at 80 degrees Fahrenheit. Make sure the potatoes are laid out separately and are not touching.
Allow the potatoes to sit in the humid location for up to two weeks. This process allows the potatoes to grow a skin over any cuts.
Wrap the potatoes in newspaper, and place them in a box or basket. Store them in a cool location.
