How Do I Make Hydrangeas Bloom Blue?

I had some hydrangeas that were blue, and now they are pink. What can I do to make them blue again? My grandmother used to dump her coffee grounds on them, but I'm not sure that's what kept them blue.

Acid content of soil is deciding factor in making Hydrangea blue or pink. Just forget whether it's high or low acid content.

Yes! I dumped my used coffee grounds (along w/ the biodegradable filter) around the base of my hydrangea bush all winter and when they bloomed in spring/summer, they were almost a cobalt blue! Just amazing.

Yes, it's the acid in the coffee grounds. I dumped my used coffee grounds (along w/ the biodegradable paper filter) around the base of my hydrangea bush during the winter months, and by spring the blooms were a brilliant almost cobalt blue. Amazing!
