I have 7 rather large plumeria and all sustained some freeze damage from our cold snap. Do I cut them back until I see no black in the cutting and it is sappy all the way around or just til I reach firm stem?

Prune all of the black parts out. I would wait to do this until there is not more threat of frost for the best results.
