Here is where life gets truly magical. If your hydrangea blooms died pink, you can plot to make them blue next year. Yes, you can! It’s all about the soil’s pH level.
To go from pink to blue, you need to add aluminum sulfate to the soil. It’s like giving your plant a science experiment. If they died blue and you want pink, add garden lime. You become a color alchemist in your own backyard.
