Grapevines and greenhouses

[Thelma Sanders]

I have a vine in my tunnel, it is doable if you keep the plant in check!

I think we need a thread on how to do it, well, I do anyway cos I've got a grafted vine on the way lol

I grow allsorts under mine. I also cut acres of greenery off them to keep them in check. My greenhouses are only 8 x 6.

Ivegot grape envy ...I'm still not sure I'd wanna use my tomato space but tell me - do you thin out those grape bunches? I get a few of little tiny green grapes in the bunch?

A lot depends on the variety, some varieties will never give big grapes, but I thin the bunches to about one per linear foot and then I thin the grapes in the bunches. You need to remove far more than you think or the grapes in the middle end up squashed (and square). I used to pollinate the flowers with a paintbrush until I realised I was just making work for myself and even if I just let them pollinate themselves there was still far too many grapes in the bunches.

My old greenhouse has a peak 10 foot high so the grapevine in the eves has little effect on the tomatoes grown beneath.

hi all,im slightly confused (quiet normal for a sun morning) all the grape growing videos ive seen on the you tubes has the vines grown in a "T" shape about 1-2 foot off the floor and the any growth goes up vertically and the grapes grow on the new vertical growth as its trimmed back down to the "T" each winter but all of yours grow up to the top of your greenhouses and then along (they look v impressive and thanks to all for the pictures) so does the glass in your gh`s stop the vetical growth or do you summer prune ? i have more questions now that i did before i started reading this thread ,not sure what to do with my new cabernet sauvingon vine now ,cheers

I give mine a good weekly haircut in Summer - otherwise I wouldn't get through the door. Here's what it looks like in Winter.

thats great thanks really good to see summer and winter photos ,how old is your vine ? and roughly how many bunches of grapes do you get ?

Hi all and many many thanks for the fotos, im deffinatley gonna give it a go in the greenhouse having seen those.
Im gonna grow it in a big pot and keep it at the back and run two arms from side to side, thatll leave the front for my toms.
If it doesnt work out at least ive tried, got my Black Hamburg from Wyevale for 6 quid , happy days.

The vine is probably about 6 years old and I should get 16 bunches of grapes. 1 bunch per linear foot (2 x 8 foot lengths) but I usually let it have 20. If left to it's own devices it would give me over 100 easily so I cut most of them off to give me nice big sweet grapes

TBL the reason they grow them in 'T's" is if you are actually setting up a line as in a "Vinyard" but for other purposes, just train a single main stem and tie it in where you want it!

But as "Greenishfing" (Fing fing fing ya clown) states, you do have to hack it back a lot throughout the season!

Jack! If possible? If ya giving it a bash, try bury it's roots outside the greenhouse and feed the main stem in, as the root prefer to be out in the cold!
