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.
But the decayed mulch is providing its own fertilizer power by this time. The results are that by very early spring (unless you live in a frigid part of the country) you will have large, sound, beautiful potatoes long before your neighbors have any to harvest. And this is only part of the beauty of winter potatoes.
