Sweet potatoes should be harvested on a day that is dry but overcast. This minimizes the chances of infection and damage that can result if the sweet potatoes are exposed to sun or rain during harvest.

The best tool to use for harvesting sweet potatoes is a spade fork. It should be used gently, starting a few feet away from the plant to avoid damaging the plant's roots.
