I agree with the above. As soon as the cut surface is dry, you are OK to plant. This year I waited 2 days after cutting and I plant mine fairly shallow, like 2-3" and then when the sprouts start to appear I add straw around them and keep piling it up as they grow.
Here is this year's potato bed. 2 rows of Kennebec and 2 rows of Lehigh Yellow.
