Disease on plants - UK

[JayLondon]

Hi,
I'm new here. I live in the south of the UK, near London.
I was hoping to find some help here as the gardening stores have not been able to help me.

I grow some vine grapes in my garden. I have a very large establish plant which is doing great.

Last year I bought a potted plant and this one has issues. All new leaves (even tiny ones) grow out with dark discolouration and rotted edges of the leaves.
I cut out all diseased leaves and stems.
The gardening stores recommended a fungal spray and I used a copper based spray from "Growing Success" on the new leaves but they still grow out diseased.

Is there a fix or cure or should I just rip it out?

There are fungal diseases. Bacterial diseases. And Viral diseases.

If you spray, and the issue persisted, you may have one of the later two. Those are usually not curable.

I would just cut out the vine, burn it, then and try again with a new one.

Most wine vines sold at retailers are suppose to be certified disease free... haha. Then there is the real world....

Thanks for the info.
I am worried that it’ll pass on to the healthy one so cutting it out might be the best choice.

Do I have to do something to the soil to make sure the next one won’t get it too?

It may be complicated...... If in the US, I would suggest contacting the nearest agricultural extension (often government or university based). In the UK you probably have similar. Suggest contacting your local "Agricultural Extension" (or whatever they are called in the UK) government office for help.

Hope this helps.
