Most of those only need a littlle help getting hooked up to the trellis, once they find it they will use it. Trim as desired (meaning I often dont) when the main runner gets to the top to encourage side branching.

Thanks for the reply. Do you encourage the plants skyward using any physical elements (such as pulling the vines toward the trellis with old hosiery)? Last year I had the same plants growing (minus the pole beans) in a row and they shot out everywhere. Just trying to understand how to keep them in their own sq ft.
Thanks!

When the plants really get going, things get a little hairy. But only on the rare occasion do I use old hosiery. Usually I just grab a wayward stem and weave it back into the trellis. Trellis neighbors mix more often than not. However, so long as I don't let one snuff out a less aggressive companion it all worked out. Usually, diferent plants would work out who preferred which berth and I'd train growth to fill empty spaces whether or not it was above the "right" square
