I've had a request from a reader to discuss my method of growing potatoes. I've grown every kind of potato there is, it seems, and in every different way I can. Over the last few years I've definitely found my favorites, and I'm happy to share them with you!
First of all, you don't need to buy seed potatoes from a seed house, unless you are wanting a specific variety that you can't get at your local market. As long as you buy organic potatoes, you can wait until those go soft and sprout, and then plant them. Conventional potatoes are sprayed to prevent them from sprouting, so buy only organic for this purpose. (Heck, for any purpose. Potatoes regularly make the Dirty Dozen list for high-chemical residues.) My local Whole Foods carries organic Russet, Yukon Gold, and both small red and fingerling potatoes, sometimes even blue. Any of these will work. Like I said, if you want something more specific, you'll have to order from a seed house. That's fun too, but I like using up potatoes that have gone soft in my vegetable bowl.
Once you have your sprouted potatoes, you can either cut them, leaving a couple of eyes on each piece, or leave them whole. Frankly, I don't bother with the cutting. If you cut, then you have to wait several days to let them dry and harden, and I honestly usually just want to get them in the ground. Planting them whole is fine, though if you have unlimited space, it's more efficient, and you'll get more yield, if you cut them.
