1 New potatoes will be ready for harvest after 10 weeks, usually in early July. 2  You should harvest all of your potatoes once the vines die (usually by late August), or the potatoes may rot.  Make sure you brush off any soil clinging to the potatoes, then store them in a cool, dry, dark place.
Mature potatoes are harvested in the fall or early winter depending on your plants and the weather. Wait until all the foliage of the plant has withered and died back before harvesting mature potatoes. 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. If the skin of your test potatoes does come off easily, wait a few more days and test a couple more potatoes.
