I've got a potted blueberry bush which we would like to add to the lotty.  I know they need acidic soil so my question is how close can I put it next to other plants such as raspberries or blackberries as the area they are in is the only space available now.  The soil isn't acidic so I know I'll have to add stuff to it to make it acidic, but don't want to damage he other plants nearby.

My poor bush needs some tlc it survives but only just, it obviously doesn't like the soil where it is.

Someone suggested half a pint of malt vinegar.

I have five blueberry bushes in with goose berry and blackberry bushes, and they do fine I  put some pine needles in with them when I planted them  (as alys fowler ?) and put a few around them as a mulch no problems with the surrounding bushes

How much work you need to do to give it the acidic conditions it needs obviously depends on how much lime there is in your soil to start with.

You may struggle to provide the right conditions for very long in a chalky soil, but for soils which are already slightly acidic digging a hole at least 1 foot wide and deep and planting in a mixture of ericaceous compost and soil should do the trick. In future years, dressing with sulphur chips or powder and mulching with pine needles or moss peat will help keep the pH low.
Make sure they get rainwater rather than tap water, especially if yours is hard.

You really should have two different varieties planted close to each other to get good pollination, and you will need to think about netting them as the fruits ripen because blackbirds in particular love them. 

I've had my two plants for at least 5 years now and they produce well despite an on-going struggle to keep the pH in the recommended range.

I built a 1m x 1m square bed using those little short fences you can buy at garden centres and filled it with ericascious (sp) compost.
My asparagus bed is one side of the square bed and there is a random bed on the other side.
I don't think much of the acid leaches out.
I grew good PSB in the random bed last year and they like alkaline soil.

That's all good to hear. Will have to get the compost this week a I couldn't today, but will move it into its new position this week. Thanks for the help everyone!
