Some of the corn made it through the process, and after she was gone, there were lots of corn seedlings that I transplanted into the big garden. I transplanted them with a fairly large chunk of soil (and pig poop) around them (think shovel transplanting), and they did fine.
So corn can be transplanted.

Tubebender said last year that he started his corn indoors all the time in order to be able to get a harvest. I think that almost anything can be transplanted, as long as you are careful with some of the more tender roots.
That’s why I like paper or plastice cups, I can just take the scissors and snip the side and peel it off. Usually doesn’t even affect the roots at all.
