Here in my little near-downtown denber neighborhood, we have tiny yards, 12' separation between homes with only one side owned. Luckily, my narrow side yard is facing the south, in sun most of the day, so I put in a small, narrow garden.
This year I decided to add hops to the mix, and rigged up a few lines from ground to roof. Does this make sense? The length of each is ~25 feet, and I transplanted a couple of rhizomes that I started inside.
