To chop, or not to chop?

Your garden looks very photogenic

 

Ours had to be pruned back as it became too leggy and then the cold weather had a go at it. We cut it back quite a lot and already it is looking far better.

 

Are the green leaves in the pic on a different shoot than the yellowed ones? If so I would just cut back the shoot with the yellow leaves, right back to the ground or close to it, and leave the one(s) with green leaves.

 

It was taken about 2 years ago Pete - it looked great for ten years until last summer. I noticed I'd tied two of the big stems, and I remembered one leaning, so maybe the wind last summer damaged them just enough to affect them slowly and I couldn't see it. Who knows? The new bits are leafing up nicely though and I'm hopeful it'll be ok again.

 

Bless you.
It is in parts, it's really just a few unfinished bits and the ugly fence at the other side.
If you look at the back fence that is my neighbour's, you can see he's built it sloping level with his side, so I put a clematis at the end to balance it out, lol, it's almost there, along with the camo-jasmine, lol, they'll stop me whincing every time I look at it.
