This is a picture of a row in my father and mine's vineyard. Got many varieties of grapes and Chester blackberries. Too bushy to incorporate more species. It does really well but we do have to watch for blackrot on grapes. We also have a kiwi vineyard that we are doing the same thing, but with gooseberries and currants. We use 12 ft posts for the kiwi!
