My hero James Crockett of the original vintage 1970s “Victory Garden” PBS fame said he just left the carefully dug tubers out on top of the former row for a few hours to dry a bit, then put them in burlap or mesh bags in a cool, dark place at once. Even with a few days of light exposure, the potatoes would turn green and inedible.
He didn’t bother with curing the crop, exactly, which is the more conventional advice today:
Dig when the soil is dry, not wet, after the foliage has died down. I normally leave them right in the ground until I am ready for them in late fall, long after the plants have faded, to reduce indoor storage time, hoping for a dry spell later in the year.
First, to gauge readiness, carefully dig a hill or two of potatoes, starting about a foot outside the hill itself and working inward, since potatoes can sprout on long roots nearly a foot to either side of where you started. (The “seed potato” from a hill I uprooted earlier, above, is the one at the end of the stem, sending off satellite roots to form more tubers.) They don’t really go deeper than planted, but go a bit sideways and even closer to the surface than the seed potato was placed.
