...

bought a new hydrangea which flowers blue in acid soils and pink in
alkaline. would like the pink so i'm planting in a pot.

had a quick look but couldn't see any alkaline bags of soil @ garden
centre.

any ideas?

bit of ground limestone around the plant (you may even get away with a
limestone chippings mulch if you are not very acid), or you could use
horticultural lime (should find it at the garden centre)
