Last year we bought a grape-vine which although may go outside, we have in a very large pot in the conservatory. My question is why are the grapes not swelling? They have developed but are now turning black but are not much bigger than a small pea. It gets lots of water and is otherwise healthy

Probably its the restriction of roots by the pot - I have known people who plant the vine just outside, in the ground, and train the growth inside, usually in conservatories which have a glass roof, and this is usually very successful, giving good crops of grapes so long as they get sufficient sun through the glass.

I agree with bamboo. also there are a lot of grapes in each bunch. next year remove a 3rd of them and then the remaining ones will be bigger providing they get plenty of water.

Thank you ladies. The nursery we bought it from told us it would be fine in a pot, if it was a very large one (which it is) unfortunately Bamboo, we haven't a suitable place in our garden to plant it. Perhaps we'll just have to enjoy it as a shading plant in the conservatory in the summer.

Well you could certainly try reducing the number of grapes per bunch next year, that might help. You'd have fewer grapes, but maybe they'd be bigger

We'll give it a try. Thanks !

I had a Grape Vine in a Greenhouse once where I used to live & with Scissors & Tweezers I used to cut some of the grapes out from the bunch so the rest could swell & reduce the amount of bunches too, if you go on youtube there would most probably be a video on there that could help :o)) Good Luck x

The Tweezers are so not to touch the bloom on the grapes.
