just keep them out of the worst weather ,wether that means inside or some shelter .they should be ok .i lost a 9 foot cordyline in the winter of 2010/11 it had been ok the year before which was similar .my mistake (i think was to mulch after a wet summer ) also lost a chusan palm (chinese windmill palm ) in the same area .if possible move them close to a building or something that helps keep away the cold
