Is it time to change the color of my hydrangea?


This is a great website (http://extension.uga.edu/publications/detail.html?number=C973&title=Growing%20Bigleaf%20Hydrange..) for the fertilizing, color and care of bigleaf hydrangea. Please note the section about color determination of the flowers. It has detailed instructions about how to bring about those changes you requested.
