Hi Sally Thank you for the advice I now have a name for the problem. I have a couple more questions. If that's ok. Do you think it would be a bad idea to remove as much of the old compost as I can without disturbing the roots, and replace it with ericaecious compost? Should I use ericaecious compost...

Thank you for the replies.

The rain has just stopped. So I'm going to re-pot it in some ericaecious compost. The one I have says it contains peat.
Elmigo, Thank you for the tip about Pine needle compost. I can't get it at B&Q so I'll investigate local nurseries.

Best Wishes

Good Morning I bought this Blueberry bush approximately two years ago from B&Q in the UK. It has doubled in size since purchased so it's growing, albeit slowly. I bought it at the end of the season because I liked what I assumed was it's Autumn colours. The problem is it's always the same colour...
