We have a passion flower that is running riot - it grows as fast as I can cut it back! I want to trail some along along the top of the fence, as we have a small (1 foot high) trellis on top of the fence. I started trailing a few bits in and out of the trellis but now it's gone crazy and is hanging down over the whole fence and it just looks a mess. It's so thick that you can't see any of the fruit or flowers. Should I have just trailed one length of it through and cut every other length back to the main branch?
