My potato plants are doing well. A few days ago I planted another row about 50′ long. I have volunteers coming up in the garden where I had them planted last year. They have small new potatoes of edible size, I figure my first planting of potatoes of this season must have edible size tubers as well. My crop from last year is shriveled and covered with root growth but they are not rotten and could be eaten, so They made it the full cycle. I have a yearly sustainable crop.
