Where are potatoes harvested?

It depends on the region and the date of plantation.

For instance, new potatoes can be harvested as early as May if planted in February in a suitable location.

New potatoes can be harvested before the plant growth cycle is complete, so they typically take less time to grow.

Potatoes that you will keep in storage over winter need to be harvested as soon as the stems dry up, meaning that all the nutrients are now present in the potatoes.

They can be harvested from summer to late autumn, as long as there are no frosty nights yet, but always as soon as the stems are almost dry. Kept longer in the soil, they will start catching all kind of rotting bacteria from the soil.
