Many tall or large, gangly shrubs like roses will need a prune now to prevent them from getting damaged by wind rock. Autumn and winter winds mean your plants get pushed and pulled around ultimately by their roots, which obviously anchor them to the soil. Roots can rip and come loose, making for an unstable, unhealthy plant. Water may even collect in the soil gaps created, which can increase the chance of rotting, too. Trim back one third of the branch growth, down to a bud, which will help prevent the worst of the wind becoming harmful. Make sure the bud is facing the way you want your branches to grow.
