Plant your vine near the wall you desire it to climb. The vine will creep along the ground until it finds the wall and begins to climb it.
Drive scaffolding poles into the ground next to the wall near were the vines grow. The scaffolding poles provide support for the vine and any fruit that you expect. If you need more support to deal with the added weight than the poles will handle, place them now. You can always remove unneeded ones later.
String strands of steel wire back and forth across the face of the wall. Attach the wire to various points along the poles as you move up the wall. The vine will select its own way across a space or into a new direction, so place as many pathways with the wire as possible.
Tie the vine to the wire network when it is young, so that it will go in the direction you desire. You will need to tend the vine from time to time, especially for ivy vines, to limit the directions you allow it to climb. Prevent it from covering windows and doors.
Prune and clip the vines back as you would other shrubs to create fuller coverage of the wall and to fill out the body of the vine.
