likely harvest?
It's difficult for us to know if you will get potatoes, what with the conditions you describe (and don't include). It sounds like you have a microclimate environment—and that can be a good thing. Just about any plant has a minimum soil temp tolerance. For potatoes, that's 40°F. A consistent 40°F. (Was that the soil temp when you planted??) If additional cold conditions are expected, esp at night, you could cover the bucket. Use whatever is handy; the idea is to retain the heat that--presumably--the pot gathers in the course of the day. Depending on how long/severe the cold is you might—emphasize might—be able to unearth the cuttings, bring them into the house in a portion of warm dirt and then replant later when temps are suitable. Or you might have to start again. It's early in season; don't let that possibility deter you. Good luck!
