Did you know that it’s easy to change the color of your blue or pink hydrangea flowers? This short video shows easy to follow instructions that will soon have your flowers blooming in a different shade.
Chemistry
Your garden soil has a measurement of alkaline or acid composition. The pH number of seven is neutral. From neutral to 14 means your soil is alkaline, and from neutral to zero it is acidified. So to change your pink blooms into blue, you will need to add aluminum sulfate to your soil.
This is available at your garden center, or ask your pharmacist for powdered alum. Mix one tablespoon to a gallon of water, and apply it around the base of your plant. Be patient. Everything in nature takes time.
To change your blue hydrangea to pink just add a cup of garden lime to your soil. The lime in the soil helps the plant absorb nitrogen while it causes it to be unable to absorb aluminum. Your blossoms will soon become pink.
You can even develop purple flowers by starting with a deep red variety and adding aluminum sulfate. Gradually the red changes, and soon you’ll have a purple hydrangea. What could be more fun in the garden than to use a little scientific experimentation, and you don’t have to spend money on a new shrub.
Now that you have reconnected with some of your basic high school science, you can accomplish great things in your garden. You deserve a beautiful garden.
