QShould Bonide Aluminum Sulfate be mixed with water?
I want to intensify the color blue in my hydrangeas.
AYou will want to blend the Aluminum Sulfate in the soil, if possible, and water it thoroughly after the application. Please see the Product Label for further information on how much to use and more specific treatment options for your hydrangeas.
