Need some help with wild grapes

[Straight Shooter]

I have one of those vines NR .....yet to get some grapes....even 1mm would be nice....the guy that delivers the coal said.....grapes do better in the greenhouse BUT the vine should be plated outside.....he said try putting up some clear polythene around the vine but leave the bottom (where it comes out of the ground outside this cover ) i must say i did move it last year because of all the work and new landscaping going on...but we are now about to plant in a new sunny location with loads of water close by .....give that a try David83.
