It won't go down.
If you try to do that, it will eventually die back to the highest point on each cane.

I just let them keep on going on their own and wave around loose up there.
Often they will arch over some.

You can drop lines down from your roof--strings on nails--to help support the canes and espalier them sideways.

Hey, that's a good idea, Cat!

Thanks catrose! Never thought about extending onto fascia of roof. I will get more roses too!
