Evergreen clematis

Our evergreen clematis came through most of the winter until the last cold snap. It now looks so sad, droopy with lots of dead leaves. How hard can I prune it? For future winter care should I wrap the main part of the plant, say up to six feet, would that help?

Good question I’m having the same problem with mine.

Moi aussi. Except mine (quite established) looks like a goner.
I would scrape a bit of bark on the stem and see if you can find some green. Prune down to that point.
