how long can cut sweet potatoes stay in water before cooking

Most commonly, sweet potatoes are harvested when the plant dies off, often as winter approaches and frosts begin. They can be harvested before this by cutting tubers from the plant. If the cut tuber exudes a milky juice that turns blackish upon drying then the tubers are not ready. If it dries clear, they are mature.

Sweet potatoes grow best with compost and an organic potato food will increase their size. I start mine from sweet potatoes rooted in water in the winter. When the vines grow from the potatoes, I cut them off the tuber and root them in water. I then plant these rooted vines in the garden after all danger of frost is past and given about 100 days to grow, they will produce new sweet potatoes. The last month or so, do not water the potato vines and this will increase the size of the new tubers.
