    When do they start forming tubers? How deep?

    They're plenty tall with good strong stems, but I dug one to see what was down there and found nothing.

    We never look for tubers until around the first frost.

    I leave the plants to die a natural death when the snow arrives and just leave the tubers in hte ground all winter. Harvest when digging after the spring thaw. So nice to have something to harvest in early spring! And at that time I know how many I want to keep for planting, too, and can do it right away.

    That's how we did it when I was a kid as well.

    Jonnie's seeds has a variety called "Stampede" that produces tubers earlier than most. I have a white potato variety and a red variety(that sported from the whites) and usually around here(except this year 'cause of drought) tubers start to form at bloom and are harvested after first frost...leaving them in to overwinter invites voles to have a free lunch all winter! BTW deer also like the plants..*sigh*
