Regular pruning is essential to managing and shaping the growth of climbing roses. Neglecting pruning is a common rose pruning mistake and will make shaping a climbing rose much more difficult.
Philip Crowther advises that you remove dead, damaged or weak stems to ‘encourage healthy growth’ as well as ‘prune long, unruly stems to redirect growth and maintain the desired shape'.
‘As the rose grows, ensure that the stems are securely tied to the structure. Redirect any wayward stems towards the desired direction and gently tie them in place.’
