Hi All,
I have a Nepanthes (pitcher plant) growing happily on my bathroom
windowsill. The original 2 vines haven't made any new growth this year and
most of the pitchers on these vines have gone brown. The leaves are still OK
though.
I have 4 other vines which apeared from the base of the old ones which are
very happy and have many new leaves and pitchers.

My question is - what should I do with the 2 old vines? Can I cut them back
a bit, fully, to the root etc? Or can I remove just the dead / dying
pitchers and leave...

Thanks,
Matthew
