All potato varieties can be harvested as new potatoes — dug up before the plant reaches maturity, while its tubers are still small. By the time that the plants have begun to flower, most of them will have developed at least some immature tubers ready for harvest.
Should you wash freshly dug potatoes?
After the potatoes have been dug, brush the soil off. Do not wash potatoes until you’re ready to use them. Washing can easily reduce the storage life and encourage mold. Store potatoes in a cool, dark area after harvesting.
