How to customize the color of Hydrangeas
Today’s Video of the Day from the American Chemical Society demonstrates how the unique makeup of Hydrangeas allow their colors to change depending on the pH of the soil that feeds them.
This means that we can manipulate the colors of these plants simply by adjusting the soil. Blue flowers emerge from acidic soil, while red flowers are grown in more basic soil conditions. Somewhere in between, purple flowers can be created.
