I don't know if it's for ramblers, but for regular climbers, the preferred way is to string wire horizontally and then tie the canes to the wires.

Some ramblers are more wild than climbers and can be put on other structures, but since this one is already against a fence, I think the horizontal wire is the best way to go. I did this along my fence with simple eye hooks and a roll of galvanized wire from Home Depot. It also bought a roll of jute twine to tie the canes to the wire. If you tie the canes to nails, they can't move as they grow and that could damage them.

Don't be afraid to prune back a lot of the rambler to get it trained. You may lose some bloom this year, but it should come back even stronger next year. And the new canes will be easier to train.

Thank you, Buford. I will put up wire on the two fences. But that leads me to another question: there are three golden showers climbing roses against the brick wall of the house. These have also been tied in to nails. They have been pruned but are taking off again - should I put wire up against the brick wall too? That will be more difficult - the roses are squeezed in beside windows.
