vegas is right, you shouldnt plant till the shell is completely removed, i have one plant that is stunted and growing slow because when the shell fell off some of the inner skin was left on the one leave, and the other leave overgrew in surface size, but was still thin, make sure that everything is clear of the leaves before planting, also, be gentle with the roots, they start really small, so if you mess them up they will grow fine for like a week or so and then just die
