When you dig them look them over carefully. Any that are damaged use up in soup or stews or puree and freeze. Get a container, put in a layer of one third sand two thirds peat and put in carrots, not touching each other, another layer of peat and sand, more carrots and so on.
You must make sure that the carrots don't touch each other in the rows or in the layers. The store them in a frost free place.
Is this a WU?
