Thank you - I contacted a local tree surgeon to see what he thinks of it.

I checked and there are no parasitic vines in the UK where I live.

I will get them properly IDed so I know what in up against.

As advised, I contacted a local tree surgeon and will see what he says about it

So just cutting it at the trunk will kill the rest of it? Will the rest of the plant die and fall off? Should I cut all of them or is it ok if i leave 50%? I like how it looks but im worried about the trees.
