Q.Passion Fruit Vine
We have a Passion Fruit vine (Banana Passion Fruit, Passiflora spp) which we want to try and move. Is this advisable? What would be the best way to go about it? Cut it right down (how much?)? It is not very big and only has 2 or 3 main stems that are about a meter and a half or so long. We have had it less than a year. Is it the right time of year (winter here in Sydney, Australia)? Any other tips or reasons why we should not do it?

Here is some information about overwintering and starting new plants:
