As insurance against losing the vintage crotons, I would encourage you to take a couple of tip cuttings from both plants, take off the bottom leaves and put in water for the winter. If they rehydrate they will probably be fine and well rooted by winter's end. They can then be potted in spring. If leaves look normal after 3 or 4 days and not droopy, they are rehydrated.
