I don’t do anything special. I cage/ stake. I usually leave 2 or 3 vines per plant. I space 3ft apart in zigzag fashion (two rows) in a 4 by 25 ft bed 15 or 16 plants per bed. I grow a mix of determinates and indeterminates . I like to grow a lot of Russian varieties, they do best in my climate. https://m.primal.net/KvPS.jpg
I like that spacing method. Good air flow between plants.
