Best start in life for a Black Hamburgh vine- advice please!

[Prim]

I'm new to this forum and really new to vine-growing.

I already have two Marechal Foch vines, which I bought last year mainly to clothe a new pergola. They're very happy where they are, and threatening to take over the world.

I have been given a Black Hamburgh vine - I understand that it is a dessert grape. It's about four feet tall, in a good-size pot, and is just starting to make some little laterals. It's in good condition and growing well, but is basically a stick with lots of leaves on. And tendrils.


I have a spot for it, which gets sun for most of the day, but am unsure whether I should enrich the soil before I plant. I have a good deep neutral loam ( and am very lucky, I know). The soil drains well.
I can provide the vine with support as necessary.

As this is a dessert grape, I wondered if adding a potash-rich feed would encourage, in time, the formation of flowers and thus grapes. I don't think I'll get any this year: it seems too young.

I am not too bothered about fruit on the wine-grapes - my intention with those was to clothe the pergola, not set up a winery - but I thought it would be nice to have dessert grapes of my own growing. I want to give the plant an optimum start in life. I understand that they're quite long-lived plants and thought that good preparation now would pay dividends later.

Any (simple!) advice would be very much appreciated.

I have a Black Hamburg.

I planted it along the sunny wall of my house and basically it got left to do its own thing.
The soil is shallow and very poor - not much else will grow there.
The house roof overhang somewhat reduces the amount of rainfall.
Being along the edge of my black tarmac driveway, facing South and in full sun, the site is very hot and dries quickly - especially as it's a bit of a wind tunnel when the wind is in certian directions.
The grape doesn't get fed, nor watered.

In some very dry years, it struggles a bit, but it always seems to come back!

Basically, my Hamburg is tougher than a weed.

I have a Black Hamburg growing in a pot. I am just using standard John Innes compost with gravel, nothing special. I think grapes are used to growing in relatively poor soil, but good drainage is important.

Black Hamburg grapes can be used for wine as well as dessert. However, it is unlikely you will get grapes ripe enough to eat, as from what I have read a greenhouse is required to this grapevine - mine is outside and grows profusley, but no sign of grapes in two years

I was made to think of where they live naturally; growing in forests climbing up trees. If you can duplicate that you're basically on a winner...
