Training a grape vine to a second floor deck
Hello! We are renting for a few years and I would like to grow grapes. We live on the second floor and we have a south facing second floor deck, but we are also allowed to garden in a partially shaded (a few hours of afternoon sun) back yard. There is a bed on the ground below our deck and I was wondering how hard it would be to train the vine to grow up to the deck. The deck is in full sun.
My question is, what kind of support should I be thinking of to help the vine get up to the deck? The first floor deck is partially shaded by evergreens so the vine would need to grow closer to the house. Would a wire stretched between the ground and the deck work? Would I need a couple of wires then?
How should I secure the wire to the ground? Is it okay for the vine to be in shade for the first 5 or 6 feet up, if above that is full sun?
Thank you for any advice about this situation! It may not be possible...
