How do you prune the David Austin roses?
David Austin himself advises to encourage a strong bush by cutting out all frail growth leaving only the studiest canes.Then prune them as to their growth pattern. Upright ones prune back by one half, spreading, arching and bushy shapes by one third. However if they are grown for display in a rose bed on their own then prune as for a Hybrid Tea
right down to eight inches from the ground.
