    Making soil ph more acidic, less alkaline will help.

    Aluminum sulfate by Lilly Miller works every time!

    Yes as Vicki said and if you can;t find that try Miracle Grow Miracid--you need a soil acidifier (not a word but it works) to get blue hydrangeas.

    My grandmother also said to put rusty nails around the plant.

    Reply a bit late but I've always used coffee grounds to turn blooms blue. Acid soil + blue, sweet soil + pink. ( lime is good for 'sweetening' soil ) I've loved the many shades of lavender blooms I often get as blooms change from pink to blue! Have fun.
