Clematis comes in 3 groups when it comes to pruning. I would look up
the cultiver to see the pruning schedule for yours..

My multi blue clematis is done blooming and the blooms are dropping to
the ground. The plant is very bushy on the bottom half of the plant with
only a couple of long vines on the top. Is it now time to prune each
vine so that I may have a fuller (dense top) next season?

Thanks, CJ in s.e.Michigan
