I'm a first year grower but I've been growing things for a long time. From the research I've done I wouldn't want my plants really near anything at all. They are invasive and aggressive growers so they require their own space to do their thing. Plus, they need lots of sunlight and planting them next to something else could impede on their ability to catch some rays.
Right now, just due to a lack of free time, I have my plants in pots on my deck. The shoots are about 6 inches long at the moment but once they get to the point where they want to grab on to something I'm going to move them down to the backyard and hook some twine from the pots to the top railing of the deck. I'd say it's about 20 feet up, and the area gets sun all day, so I think it'll be a good spot for them. Nothing else is planted in the back yard too so I think this would be the most ideal spot for the hops.
Hope this helps; good luck!
