Does anyone have any advice on growing climbers. We share a fence with a neighbour (nobody knows who owns it officially) and I would like to grow climbers up it but I'm not sure how. My neighbour has loads of stuff growing and I don't want to disturb it but I can't see how to do it without adding support to the fence. Is there a freestanding option or a method of adding support that doesn't affect the integrity of the fence? Thanks.
