Grape vines

I am in N Wales and last year planted Black Hamburg for the green house and  Larkmont for outside. Went to local garden centre for advise and what to grow, and this is what they suggested.

Lakemont?  I've just put one in the Polytunnel and the guy at Rogers of Pickering reckoned that the seedless varieties need MORE protection than the seeded.  He said if it drops below 5 degrees then you'll lose your crop.

Might be an idea to put the Lakemont inside...

I was told the exact opposite ,bines are very hardy plants.

What you want for a chance of success is a south facing wall to grow them against. This will give some protection against a late frost when they are flowering. I grow them against a south wall down here in France although they would be OK out in the open. Incidentally don't buy any new plants save really good ripe wood pruning's about 18 inches long  and cut straight through the bottom most bud wrap them in news paper and soak in a bucket of water over night then place then in a plastic bag and put them in a warm place for a couple of weeks they will form a callous which indicates they are about to send out roots. Pot them up and put them on a warm bench keep well watered and they will root. I normally plant out when I can see roots coming through the bottom of the pot dead easy and cost effective.
