Cindi I cut very little, because it had so little healthy foliage! And I read one page, when I was looking for guidance about the move, that suggested just watching and waiting to see which foliage began to die back on its own and then trim that off. This based on the fact that the plant uses the leaves to make its nourishment and the idea that the plant "knows" best which leaves it can no longer support.
What everyone seemed to agree about was watering very copiously in advance of the move. Like once a day for a week, in order to give the rose a chance to fully saturate all its tissues, because with the root loss it would be a while before the hydration flow would be restored. That made a lot of sense to me.
