Passion flower vine

I live in Charlotte NC. I understand the vine of the passion flower dies back in winter, but should I cut down to the root before or after a hard freeze and mulch it, or not cut down at all? It is over 15 feet long.

While these plants will normally die down for winter dormancy, thus, not requiring too much pruning, since yours is quite large, cutting it back by about a third (or even half if not more) might make it easier to fit the plant inside.
