Blueberry bush -? I live in the UK and enjoy had a blueberry bush contained...

I live in the UK and enjoy had a blueberry bush contained by my garden for about 3 years very soon. It doesn't seem to own grown much at all so i moved it to a more sunnier place. Is at hand anything else i can do to help it?
Answers:    Blueberries close to an acid soil. Perhaps examination the soils they are in next to a PH tester. They do like their food, I pass mine a liquid fertiliser for sour loving plants every 4-6 weeks and it is very cheery.
Sure, I could come over and help prune it and as expected harvest some of those blueberries...plant another bush too !Just that simple.
