In general, this was a pretty useless video! Most people know how to use string… What’s the best method to set the framework? Horizontal wire? If yes then how far apart should the wires be? Trellis? What about damage to old brickwork? How best to attach that to the wall/fence? The balance between vertical and horizontal relative to flowering/growth? What about on a corner wall, on two planes? What about pruning, leave the rose framework and lightly prune or prune hard then reset the framework each year? Should ramblers be treated differently from climbers? You’ve missed an opportunity here to educate newbies!
