I see that you don't have the big azz maple trees that I have.
I would have to plant 2 doors down to do what you are saying
My plan is to run some 20 foot poles ( be it PVC or steel) next to my fence on the north side of the house ( making it south facing) and run a rope from pole to pole (thinking 3 totaling 20 feet apart) and then stringers down from the rope to the ground where I plant the hops.
