Grape vine quandry
Hello all, I've just moved allotment sites to one that gets a lot more sun, but hasn't been properly cultivated for the past 3 or 4 years. On the site are 8 established grape vines, currently at 2ft and growing through grass and stones. Don't know the variety or why someone thought Cumbria was the natural place to grow them! Shall I pull them up, prune them or leave them?
