My cultivated Blacberry has completed its cropping. Time to prune and train.
First all this years fruiting wood is removed right to ground level.

Next this years growth which will fruit next year is pruned and trained in to the vertical support. Although thick the stem is flexible and can be bent serpentine fashion secured with strong nylon cord or insulated wire.
