True Welshonion. Have to admit to never having planted a dry one. I move them green and don't move the big ones at all.
I think they mound up and expose themselves () having started below ground but I've never done any experiments to prove that.
Just check RHS who say an inch. I think I'd cover them and leave them to sort themselves out, being exposed with no root growth through the summer is much the same as being stored dry, they don't like that
