Devon, United Kingdom
I have some decking, 3-4 feet from the ground. For the last 3 years, I have grown grape vines between the posts that hold up the decking, and above the decking along wires under the fence.
I have now added some posts that go 7' up from the decking, and added some horizontal beams that go from the posts to the house. I intend to thread wires through the beams to persuade the vines to grow like a roof over the decking.
How should I prune the vines so that they spread over the beams above the decking? Cut all branches away except the main ones, and tie them to the posts? Or just intertwine all the branches up the posts?
Thanks for an advice.
