My grandmother always said to put a rusty nail in the ground next to your plant, that will change the color.

Rusty nail is for iron deficiencies. I think you add aluminum sulfate to the soil to get the blue color.

Hydrangea blue or purple blooms come from highly acidic soil. You don't need to buy some chemical additive; you can get acidic soil by dumping your used coffee grounds on top of the soil.
