Why no grapes on my vine?

[Easipeelerie]

I had a vine in a pot for many years and grapes didn’t grow. About 4 years ago, I moved it to a very large pot and grapes appeared. I had a couple of years of lovely bunches of grapes. The following winter, I forgot to prune and the pot got overrun with ants. By summer, there were some grapes but way fewer than here had been and they and the leaves looked a bit pathetic.
This winter, I pruned and I’ve kept the vine watered and fed since weather has warmed up. I now have fewer ants, a lovely luscious looking lot of leaves but not a single tiny grape. I think, if there are going to be grapes, they’ll have started to grow by now?
Anyway, just wondering why they’ve not grown and when they’ll be back. Could it be the ants last year (though come looks happy now)? Or could it be that I didn’t prime them pruned too much? There are still ants but I don’t think they like the moist soil so I didn’t see them all the time.

I'm not a keen / knowledgeable gardener but I have been sitting underneath my vine this lunchtime and it hasn't yet got all it's leaves out let alone grapes! The grapes come much later on, after the blossom / flowers have died back.

So 1) it's a bit early (I'm in the south of England)
2) did the frost kill off the blossom ? Because if it did, there'll be no grapes

Thanks - this is helpful.I was looking at old pictures of the vine and could see tiny grapes in May.
No idea if frost killed blossom. I’m in the North West so not the warmest, though the vine is in a south facing position.

I do t know much about grapevines but what I was told is not to prune it. Ours was here when we bought the house and we did nothing to it for about seven years, completely ignored it, and we had grapes every year. Since we’ve had a gardener who likes to keep on top of it, we’ve had no grapes at all!

Perhaps I’ll leave it from now on, and see what happens!

Hello Easipeelerie,

Happy gardening

It had a setback last year, so it might be putting its energy into regrowing a root system this year. Don't give up hope though, it may produce something yet.
