Q.How much and when to prune clematis?
How can you tell whether the clematis flowers are on last year`s wood or new growth? If it flowers on new growth, should this be cut right back? Ours are growing in a basement gulley, so sunshine is much better at higher levels. Does this affect the pruning?
thank you for the advice.

You have to know the flowering time to know when to prune these. A general rule is to prune them directly after the flowers die for the year.
