Hope someone can help here. I have tried googling to no avail. I have a passion flower (the common variety) which is about 4 years old and was growing really well over a pergola we have attached to the house - we were getting a really good covering over the top. Now although the part of the stems that were growing up the post are still OK and the last 3 foot or so are still OK with lots of green leavers the middle 6-8 feet or so is looking dead. Do I need to cut it back or should I be patient? Just I thought that the sooner I cut it back, the sooner it would rejuventate so I really ought to be making a decision.
Thanks.
