Growing grapes

I have just planted a grape vine. I had a grapevine in my greenhouse at my other plot which did well but was not seedless.

This Dutch variety is seedless and is supposed to do well in the British climate. I searched my ramshackle greenhouse for any broken panes and noticed a triangular section of glass missing from one of the bottom/centre panes. I dug a hole (after raising a paving flag) and planted the grapevine with a lot of potting compost around it. The vine itself was fed through the gap, and after moving a potted tomato plant I fatened the vine to a cane tied in to a lug on the greenhouse frame. The vine is about 1 metre high and hopefully will put on some growth to get it to the greenhouse eaves. I then have a choice of training it up to the ridge or along to the greenhouse back.

I would like to train it in two strands along the back side of the greenhouse above the potting bench.

No need to comment as I only started the thread because there were no grapevine threads in the fruit section.
