I brought a grape vine 3 years ago and it was about 2 feet tall at the time, this year we still don't have any sign of grapes but looking into it we might not be pruning it correctly in the winter. I was told to cut the shoots back to close to the main stem but now I think we need to make it grow horizontally and wanted to ask for a bit of advice to make sure we have the best chance of fruit next year. I have drawn a diagram to show the current state of the vine, any help would be really appreciated, I don't know what to cut and what to bend so I really don't want to make it any worse!
