Some years ago a friend of mine had a large stone fruit farm up near Lake Makoan in Victoria,he had his fruit on wire vines aggressively pruned to produce small amounts of fruit per tree root but large in size. I'd never seen this before but he said ALL of his fruit went OS, none made it to market here as he got considerably more $$$ from OS buyers!
He's now long gone sadly as is his once magnificent fruit farm (due to our wonderful corrupt Govt) on the edge of the lake, as well as his PA39 & C210, loved flying them both🛩👍
