Thanks for your question about hydrangeas. Here’s an Extension article about these plants that explains how changing the soil acidity may be able to do that: http://extension.oregonstate.edu/benton/sites/default/files/handout.pdf Typically, the more common macrophylla (moptop) is easiest to impact. But you may have a variety that is more difficult, since some won’t change regardless of acidity. Be sure you don’t apply more sulfur than the package indicates. Good luck!

Hi Kristena that link does not work.
