I grow potatoes in zone 7/8 and rotate the plot through a 3-year cycle. Last year I ordered potato tubers from Pinetree seeds for the first time. They arrived late for my area, but I planted them immediately. The first potatoes I harvested in early summer were fine; a couple of weeks later, almost all the potatoes were rotted and had a horrible smell--reminding me of tales of the Irish potato famine (although the leaves of the plants were not affected). Question: how may this affect future potato crops, even in other beds? When is it safe to replant in that bed? Anyone know what my potatoes had?
