I have trained Passiflora to grow all around the top of the green house.  The stems are healthy but the flowers no longer appear.  Do I cut it right back or leave them where they are?

    Any help for @Oldcompost
  • Fran IOM:  It's the first time no one has responded to a question asked on this forum.  I think passion flowers are so beautiful.

    Let it overwinter with the growth on as this gives it some protection if theres hard frosts or snow. Then in April when you see new growth starting cut it back to where you want it.

    I’m a bit puzzled ... is this inside or outside the greenhouse. 
    Which passiflora is it?  The hardier one or one of the more tender types ?

    Photo might help. Mine is tough as old boots so mystified.
  • My passiflora is a monster it's spread along my boundary fence and is now covering over 10 metres. Mix of  flowers and fruit all summer long. Don't  do anything to it apart from some bone meal and compost mulch
     I live in Northern  England  and it did not even the Beast from the East.

    Mine is still flowering also
  • It is grown from a huge pot inside the green house which never freezes and it's the all white one.  Two more died in another pot as the large leaves of a sikkim cucumber alongside starved it of light.

    So it's possibly P. caerulea 'Constance Elliot' .... which should be fairly hardy and fine in a cold greenhouse, providing it gets the conditions it needs.

    Scroll down and click on your plant for details

    It should be fairly evergreen, so I would leave it until the spring and then just cut it back and tie it in to fit with where you want it, removing any growth that has been frosted or scorched as you go.
