The last frost may not be until end of May. Soil is wet. Will they rot or even freeze if i plant them this soon? The reason i ask is because last years leftover crop is sprouting like crazy. The box is full of potaotes with 6 to 10 inch sprouts. Do I still need to green them first? Some of the sprouts will be broken when I remove them from the tangled mess. They will grow back, right? Should I plant them in containers inside? What kind? Advice please.
