That's the recommended approach from nurseries and most people succeed with it. Note that the southern 'highbush' and 'rabbit eye' varieties are happy with pH in the range 5.5 to 6.0, while the northern and European species of Vaccinium thrive on a lower pH of 5.0.
Products sold as 'Hydrangea Blueing' are usually ammonium sulfate with a buffer. Great for lowering the pH. Granularized sulfur also works but watch out -- it is slow release and can come on strong as time passes. Be sure to get an inexpensive pH meter (~$15) and check the soil prior to adding more acidifier.
