Clematus montana or triffid?

Hi. We have a clematis Montana growing over a shed. It has been neglected for the last couple of years and is now just a tangled mass of woody stems. It is covered in buds though and so I am wondering when I can safely cut it right back and thin it out? Thank you so much for your help again.

Cut it back after it has flowered that way it still may flower next year as it only flowers on last years wood
Yes indeed, immediately after flowering and that should happen in teh next few weeks.
You can then either give it an overall hair cut to tidy it up and cut a few main stems at the base then leave them to wilt before pulling them out or cut the whole thing back to low pairs of leaves and then train the new growth where you want it to grow. Whatever you do, make sure you give it a good feed of proper cleatis food and a liquid tonic of rose or tomato food to give it a boost.
