Potatoes are ready for harvest when the foliage first starts to die and turn yellow. Early (new) potatoes can be lifted earlier (no earlier than June ) to get the very tastiest potatoes. In this case, harvest them about a week after the potato plant flowers first appear. New potatoes only produce a couple of handfuls of potatoes per plant, so dig up the whole plant. After flowering.
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.
