There are blueing powders in the garden centres based on aluminium
sulphate(?) I think.
There are also claims that sticking (iron/steel) nails among the
roots does
the same thing. The colours are the opposite way to litmus paper so
you are
looking towards an acid soil.
I am trying a mixture of iron and aluminium roofing nails, but I did
put
them there before the winter.
If all the hydrangeas in your street are pink, you may be in for a

Jim, I've tried your method, mine still flower as pink!!! The only
ones that do come up a beautiful blue colour each year, without any
additives, are the Japanese ones.

They were. I have taken cuttings of a white one which have all taken,
do you know if white have any problems keeping true?

Fraid so my whites come pink or blue or sometimes both but never white!
except the year I bought them
