Blackberry pruning time

My thornless blackberry vines have been running all over the ground, and now that fruiting has finished I've taken the opportunity to tidy them up and prune them.

Messy vines before pruning

I followed this advice - cutting them back to the main canes and shortening the runners substantially.
I had such a great crop this year, I'll do what I can to encourage more fruit next year too!
A bit more work required to tie them up to the trellis, but they're looking better than yesterday!!
