20 year old grapevine, please help me with it

[thatlad1]

I have taken over an allotment last september, on it is a greenhouse that i have restored, it is about thirty foot long and in it is a grapevine that is rooted outside. i have tried to train the vine along the inside of my greenhouse and it sought of worked. It is now growing rapidly with lots of foliage and some bunches of fruit appearing, i desperatly want to produce some fruit of the vine as i am told it has been grown over the last twenty years and it would be a shame to let it go but it is taking over my greenhouse and i just dont know what to do with it. PLEASE HELP.

Hi there.
Geordie Geoff here (AKA Open-Cases), I have my vine (Black Hamburg) growing in my 19ft x 6ft greenhouse, what I would suggest (whether right or wrong) is to forego any fruit this year, for the sake of getting the vine trained to a shape in keeping with the greenhouse, I trained mine along the apex of the house, then trained spurs down the roof glazing bars alternatively, allow only five leaves on these for next seasons fruit, and keep them to this format, works well for me, and have been doing it this way for the last seven years, the grapes are 100% better than commercially grow, and you don't want to use chemicals if at all possible. Hope this is of use to you, even though it will be a little late for this year. Good luck
Geordie Geoff

P.S. the vine is 28 years old now

My vines area little older I think, but I could do with the advice too! My house was abandoned in the late 60's
One vine seemed to produce flowers in the late spring but none of them have produced any fruit. Could they be just too old now?
