digging potatoes
Wow—if you haven't turned them up yet, lucky you! Potatoes can be harvested anytime after the foliage—the green leaves and stems—fade and die. This being nearly the end of September, they should be ready or nearly so. You can check but gently digging one of the plants near the end of your row (presuming the plants are in rows) or any one plant that will not disturb the others. Dig by hand, not shovel, to avoid slicing into a potato. (So this is more like moving the soil away from the hill you've created.) Try to find a few spuds. If they look "good"—done, ready—you can probably harvest them all. In any case, take them before the frost, and see the notes above for cleaning (do NOT wash until ready to use) and storage. We hope this helps!
