Having sweated blood in removing a common ivy that was growing up the gable
of our house, I'd now like to train a Virginia creeper up there instead.

There's been a VC growing by the gable end for some time but it's never been
able to get a good enough grip on the painted pebbledash to gain any height.
What's the best thing to train it up? Trellis, plastic mesh, vine eyes &
wire or something else?
