grapes in a glass house?

Hi all, I'm wondering whether it is worth me buying a grape vine? I would only be able to keep it in an unheated glass house! Would this be okay in your experience?

thanks,

Yes, I believe so. In fact, I have a grape vine which is quite happy outside on a South facing wall, but it doesn't produce very good quality grapes. I don't know if that's because of temps, watering or some other factor.

I suggest researching varieties carefully and buying a good one for your purpose. Also, if grown in a glasshouse I have seen the root planted outside with the trunk trained through a gap to the inside where it fruits - so investigate if that is necessary or a good option in your case.

 

Great answer

 

two good varieties are ;

Fosters seedling & Black Hamburgh

 

This sounds promising.

The grape I was thinking of growing was actually cultivated on a country estate about a mile away from me. The estate no longer operates but perhaps the original plants were grown in unheated glass houses? Might be worth a try.

thanks for the replies.

I used to have a Muscat of Alexandria in a cold greenhouse, it did reasonably well but often ripening very late and some times suffering from botrytis.

If you are growing under glass you can pick much more interesting varieties and avoid those which are mostly wine grapes.
I'd consider trying something like Flame or Thompsons seedless, there are others that are newer varieties.

 

Mine is a Madeleine Sylvaner, I suspect this is a wine grape not a dessert grape. It produces quite a few bunches but the grapes stay small and often split as though watering is an issue. The flavour is good although they are very seedy. Also, it is inclined to get a bit of powdery mildew late in the season.
