Hi- Have naively planted 2 passionfruit vines to cover a trellis then learned that this will not be nearly enough space for these ever-growing/stretching vines. How hard is it to transplant these? I do not want to kill them. I heard a speaker on the vine, and now am scared to cut back too much, but I have read here about people keeping them contained. I am planning on a 8-10 foot wide and 5 feet high trellis. The gentleman said that you get your flowers and new buds on the new growth, so if I needed to keep it cut back as it has nowhere to go, will I ruin my chances of its bearing fruit?
