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..
Likewise, can you dig potatoes before they have flowered?
When the flowers appear on the shoots and stems of potato plants, it's a sign that the potato tubers are maturing. With maincrop potatoes, wait until the stems have died down completely before lifting. As a guide, harvest first and second earlies 10-12 weeks after planting.

After the foliage has died, dig up a potato from one or two plants and rub the skin of the potato with your fingers. The skin of a potato that is ready for harvest won't scrub off easily.
