Overwintering Passion Flower Vine
I am Zone 3 in east central AB. This year I planted 2 passion flowers and a John Paul 11 clematis in pots around my obelisk. I have just read the tips on this site and I want to bring my pots inside and store them in the dark, cold room in the basement for the winter. My question is, can I cut the vines off a couple inches above the dirt, or how much do I need to leave on the plant? Obviously, I cannot bring the whole 6 ft obelisk and 4 potted plants inside. Should I water it well first and then just forget about it for the winter? Any suggestions will be appreciated.

Generally, it will die down on its own but you can go ahead and cut it back by about a third.
