That's sure a nice idea how to build up trellises, and might be of help for me. Several years ago, I planted the hops from the woods in the yard of my house in down town St.Petersburg, and I believe I had chosen not exactly the right place for it. Every year I see as it struggles to grow from the shade on the western side of the stone fence. I believe, when it reaches the height of the decorative grid (about 6 ft from the ground), then it starts growing faster, cause there's sun there.
