Recommended compost for Redcurrant, Grape and Raspberry plants?

[Inastate]

I've just done a test on my garden soil and it appears to be Alkaline, as does my home made compost.

I've just re-potted my grape plant and the root system wasn't very well developed, and I take it that's probably because last time I did this I used my garden compost, but the pH needs to be slightly acidic.

So basically I've just repotted it using Aldi 'seed and cutting compost' which is made of 'moss peat, sedge peat and green compost' and is apparently pH balanced.

I think I might as well just bit the bullet, re-pot the plant and ensure all my fruit plants are potted in a slightly acidic compost made for fruit plants.

Can anybody recommend a particular kind of compost which would work for all of these? Thanks

Seed and cutting compost is no good for mature plants, as it has hardly any nutrients in it.

Do you have to have your fruit in pots? They do much better in open ground.

.... the pH needs to be slightly acidic.

I have all my fruit planted in somewhat alkaline soil. I don't add anything to it, apart from the odd mulch of comfrey leaves if I remember
