How long do potatoes last in the ground?
Harvesting & Storage
First and second earlies can be left in the ground until required but it's not recommended to leave them beyond 2-3 weeks after their due harvest date. If they are left in the ground too long they will lose that fresh new potato taste as the skins begin to harden and thicken.
Is it OK to leave potatoes in the ground?
You can leave them in the ground until needed, and they will keep growing larger, but the longer they're in the soil, the more likely they are to get damaged by slugs. Dig up potatoes carefully, inserting your fork at least 30cm (1ft) away from the base of the plant to avoid spearing the tubers.
Why are my fresh dug potatoes rotting?
Abrasions occur during handling especially if the tuber is immature and has not set its skin. Lenticels swell when tubers are exposed to highly moist soil or standing water for several days. When the bacteria enter the tuber, the cut, abrasion, or lenticel begins to discolor, decay, and even liquefy.
Will potatoes rot in wet soil?
Potatoes perform best in areas where summers are cool (65 F to 70 F), but are widely adapted. Potatoes require well-drained soil. (They will rot under prolonged cold, wet conditions.) If your soil is poorly drained or a heavy clay, consider using raised beds.

Digging and replanting them the following year maximizes each tuber's production of new tubers.

The overall production will be less than if you had dug and replanted them.

Avoid excessive soil moisture before harvest to reduce lenticel infection; use clean water to wash potatoes; and avoid water films on tuber surfaces during storage. Postharvest curing and storage temperatures can be a critical component of soft rot management.

While it may be tempting to rinse off the dirt before storing, they will last longer if you keep them dry. This is because washing adds moisture, which promotes the growth of fungus and bacteria.
