Hi! We planted potatoes last summer and then didn’t end up digging them up. We dug them up today (early April). Can we eat them? Can we use them to start new potatoes?
If the potatoes are still firm and the skin is not green, yes, then you may certainly eat them. When you harvest them, inspect them for diseased looking tubers. If the potatoes appear fine, then yes, you can also use them to start new potatoes. Though it is recommended to plant certified disease free tubers.
Practice crop rotation and plant the potatoes in a different area than they were last year.
This OSU Extension publication, Grow Your Own Potatoes, provides more complete details regarding potato cultivation in the home garden.
