Passion flower vines
I have a passion flower vine in a pot that has outgrown the trellis I put it on. Can I untwine the shoots and put it on a new trellis, or would I hurt it that way? What would you suggest doing? Thank you.
I would suggest cutting the plant back pretty hard, say 2 or 3 feet of plant left sticking out of the ground, when it slows down in growth for the year. It may or may not go dormant in your area, so you if you can't wait until dormancy, then cutting them after the blooms and fruit drop will be your best option. You can, then, unwind what is left, and replace the trellis.
