I have 2 grapes that I planted 12 or so years ago. I had sort of a gazebo structure that was already there and I was trying to create shade as I live in California's hot central valley. They were planted about 4 feet from 2 of the poles. It was built with scrap lumber. It is tall, 9 feet so when the grapes were babies I stretched out an old piece of hog wire between the two poles for something for them to climb on. After a few years they grew up to to top so I was able to take the hog wire down and tied the vines to the 2x4's that were attached crosswise on the top of structure. Then I just let them grow. They created some nice shade and easy access to the fruit when I was ready to harvest. 3 years ago a friend built me 2 sheds on the sides of the gazebo for garden tools, etc. Turned out good even though somewhat unconventional for a grape trellis. Has nice shade on hot afternoons.
