Thanks for all the questions. I put this trellis in place over 6 years ago, so I will do my best to remember how I put it up.
Jo Ann's pergola is the best suited structure for a hops vine, but I don't have a spot for a pergola in my small city yard
My house is a bi-level, so the over hang is about 4 feet from ground level. Just so happened that was a good spot to secure the two trellis' to the house (that's the only spot that it is attached top the house). It has held up through high winds very well. I have never had it shift or move away from the house.
I did it myself. I attached the two together 1st, flat on the ground. It's important to make sure the zip ties are as tight as can be and the more the better
It is leaning against the house, so the very top is the only spot that it is flush and touching, but there is a space for the vine to twine the entire height, excluding the very top where it is leaning and touching.
Here's the photo's again that will open bigger (my computer system is due for an upgrade and it didn't work in the article)
