Which direction should grape vines be positioned on top of pergola?
On a pergola (18ft by 13ft) with 4 posts, how do you position the vines once they reach the top? Do you align it at the very edges with the beams or do you bring it closer towards the center onto one of the rafters?

I would position the primary leaders toward the center and rafters. They will branch and those branches can be positioned outward away from the main stems toward the edges and open spaces for an even distribution as much as possible.
