pick your own. I do it at farms all over the place around here all the time. nothing to it.
Where do you get your potatoes?
Do you think Simplot would have died such a Rich man if he had to pay normal wages?
i grow about 1/3 of my own. potatoes store well too. when i retire I am going to start doing a little more with hydroponics too. i've had some great success with lettuce, spinach, swiss chard and stuff like that already that i can keep going year round. potatoes are someting that will take a little work, because you have to keep the root in datkness.
Most do not grow their own potatoes.
