Help with Clematis
Please can anyone offer some advise on when and how best to prune this Clematis?
It has been left to grow for many years and I would like to re-paint the wall and add some trellising to help it.
When is best to do this job? Now or in the spring?
Also I am concerned about the 'peeling' at the base of the main trunk of the plant, I hope you can see in the photo.
I have also attached a picture of the flower to help with identification of the variety.
Would really appreciate some advise, I frightened that I may up killing it!
