If you bury the plants that have leaves you might lose them (that is, they might not thrive). Are they so close in the container that you can't find a happy medium; that is, pile soil on some but not others??
Without knowing more, we can only suggest that potatoes usually need a good amount of space betw plants (some sources say 36 inches); growing in a trash can lead to more crowding than usual. If that's what you face, do what you can to keep the hardiest of the lot thriving and consider this experience if you try it again.
