Grape Vine

I bought a mature grape vine last year (the most I've spent on one plant!) as I just loved it's knarled trunk, and the idea of growing my own grapes appealed.

It was bought in a HUGE pot which took both my partner and myself to move with the help of wheels underneath which we have kept it, and put it in our greenhouse.

Both last year and this year we have had no flowers appear on it, and no flowers mean no fruit! The plant has produced an abundance of healthy green leaves - but that's it! I have fed it regularly, and also replaced the top 2" of compost, but I must be doing something wrong. Any advice would be appreciated as I would love to have grapes next year (even a small bunch would be a start!)

 

I'm not sure you need to buy such a large plant in order to get grapes in a year or two.

A picture would be nice but I'm guessing its an old vine thats been up rooted and potted, and as such is not really happy.

Without a picture its difficult to say as to why your not getting flowers, but pruning could have some bearing on the matter.

 

What kind of grape is it Gladdycat ? And where are you in the country?
I don't think grapes need or want to have their roots in the greenhouse.
Generally they like their roots out in the ground and maybe their heads in the greenhouse.
I'm in Perthshire and I have a Black Hambourg planted in the ground and growing up the south facing wall of the house. I get a few bunches of grapes from it.
A few miles from me there's a nursery which has vines planted outside an old greenhouse and the heads inside and every year the black grapes are hanging in huge bunches.
No expert here but maybe you're being too kind by having the roots in the greenhouse. I think they like to be out for a winter.

 

Thanks for the info. folks! Alice, I honestly haven't a clue what type of grape it is......it was very much an impulse buy (if I'd stopped to think the price would have put me off lol !!!!) I live in Co Durham, and my garden is pretty sheltered.

The problem will be getting the vine into the ground as my greenhouse is on a paved area. My next door neighbour has some younger vines with their roots outside, and their heads in their greenhouse, and has had exactly the same problem as me - loads of leaves and no flowers.

I was wondering if pruning could be the answer? I know they should be pruned at the back end of the winter but I have to admit I don't know by how much, and am a bit nervous about tackling it.

 

There are complicated types of pruning grape vines, but I've always found the easiest to be the one that involves growing one or two main stems.
You then cut all growth back to these stems in subsequent years, leaving one bud at the base, this grows in the spring and carries the flowers.
However constant summer pinching or pruning is also required otherwise you just get the masses of leaves.

Main thing to remember is, never cut into brown wood during the growing season, it will bleed sap.
