I am considering a property with an older vineyard, and according to the listing information most of the vines will need to be replaced. From some quick googling, replacing the vines seems to be a very big investment.

I am wondering what else I could do with the infrastructure, or if it would be foolish to take on this property unless I am intending to restore the vineyard to a productive state.

My first thoughts were market gardening using the trellising for tomatoes and cucurbits, and growing some greens and root crops between the trellises. The irrigation infrastructure for the vineyard is intact, and I am assuming it may be a bigger challenge than I realize to modify it for market gardening.
