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.
You can leave the potatoes in the ground for a few weeks longer, as long as the ground is not wet. New potatoes are small, immature potatoes. You can harvest a few of these without harm to the plant, once the plant reaches about a foot in height. Gently feel around in the soil near the plant and lift them out.
