Your hydrangea may not be able to turn blue it depends on the variety.Most hydrangeas, except white ones, change color based on the pH or acidity levels of their soil. To get a blue flower head you will need to apply soil acidifier.
'The power of accurate observation .... is commonly called cynicism by those that have not got it.
You can't really 'change' the soil type you have. If you have a pink hydrangea, that's it - it's pink. It may alter slightly depending on the acidity/alkalinity of the soil, but it won't make a pink one blue, if that's what you're trying to do.
If your soil isn't suitable for the colour you want to grow, you can grow them in pots or containers.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
My hydrangea is pink , I've never tried to change the colour.
I was told long ago by an old Gardner to stick an old piece of iron in the soil right next to the plant to get a blue flower. No idea if that would work as I've never tried it.
As fairy girls says if you want to be sure of blue heads grow them in pots where you can tailor the environment to the plant in question.

Be aware that watering the pot from the tap will also sway your soil into being alkaline over time, especially if you live in a hard water area. Other than that, use a water butt but it can be difficult over Summer.
