help required on how to grow grapes

[alistb]

I would like to know what would be the best way to grow grapes in a 8x6 greenhouse. I was thinking of one green and a one red, not for wine making.
Option 1) grow in a pot. If so what size of pot.
Option 2) make a bed, currently grow everything in grow bags or pots (tomato)
Option 3) plant roots outside of greenhouse taking the rest of the plant under the frame of the greenhouse and support it. please note I am in central scotland so a variety that is reliabile to ripen

You're going to be pushing it to grow two grapevines in that size of greenhouse. Having said that, if you are determined to go for it then plant the roots outside and lead the vine(s) into the greenhouse.

Hi Alistb, i'm in your neck of the woods and have a grapevine this year. Haven't done anything with it as yet. It's in a large pot around 30cm but I was planning on planting it directly into the greenhouse border this winter.

I'd read about planting the roots outside but I wondered if I'd need to do that, I imagine that the ground temperature here, even in an unheated greenhouse, wouldn't be any warmer than say outdoors in Italy in the winter? Maybe it's wishful thinking on my part as it would be so much easier just to plant it inside.

So i'll keep my eye on this thread and hopefully get some advice along with you

As Rusty Lady says you would be pushing it to have two vines in an 8x6. However plant them outside and lead the rods into the house. The roots won't be affected by frost. Mine have survived -19C with no ill effects. When they get going you will need to be ruthless with them and take off all the unwanted growth very frequently. Go for early varieties and they should ripen.
