Edible Vine is looking sorry for itself

Just for the record, it looks pretty normal to me also.
As long as the leaves drop off, its OK.

Then perhaps a trim back to good strong buds lower down, in order to remove any unripened wood.
It will then grow like the clappers next year.

 

Trust me if you lived in central scotland like me you wouldnt even have attempted to plant that outside or even in an unheated greenhouse. The most exotic I grow in my unheated greenhouse was italian peppers. Which is pretty dismal.
