How to Change the Color of Your Hydrangeas

Purple and blue hydrangeas are in bloom.

Are you tired of your hydrangeas always blooming the same color? Or maybe you’re hoping to add some variety to your garden this year? If so, then you want to learn all about this simple trick to change the color of your hydrangeas.

The answer is a common kitchen ingredient: vinegar!

First, determine what color you want your hydrangeas to be: blue, pink, or somewhere in between. If you want blue hydrangeas, you’ll need to increase the acidity of the soil. If you want pink hydrangeas, you’ll need to decrease the acidity of the soil. Lavender is right around the middle.

If you don't have a garden measuring cup yet, now is the time to snag one!

To increase soil acidity, add one cup of white vinegar to one gallon of water and water your hydrangeas with the mixture. Repeat this process until you see the desired blue color.

To decrease soil acidity, you’ll want some baking soda. Add half a cup of baking soda to one gallon of water and hydrate your hydrangeas with the mixture. Repeat this process until you see the desired pink color.

Keep in mind this method won’t work for all types of hydrangeas, as some varieties are not affected by soil acidity. Additionally, it may take a few growing seasons to see a noticeable color difference.

Overall, hydrangeas are very low-maintenance plants that are easy to grow in most gardens. You’ll enjoy them no matter what color they end up!
