What happened to my blue hydrangea?

Last year I planted a hydrangea bush of the intensest blue. This year it is reverting to the more normal pink. Older peoples' wisdom (opw) is to bury rusty(?) nails in the soil alongside it to keep it blue.

Try mixing alum (from a chemist)or a sachet of special 'Hydrangea blue' from a garden center in with the soil.

Im playing with the armature you kindly left. Thank you xx
