Last year, we gave readers a few tips on changing your hydrangeas’ color. We hope you enjoy this excerpt with a few new tips and tricks!
Certain breeds of hydrangea do change, and it’s possible for a grower to control the color of those blossoms by tweaking the soil. These tips will help ensure a successful switcheroo:
- Hydrangeas’ blossom colors rely on the pH of the soil.
- White hydrangeas do not generally change color.
- Looking to change your pink hydrangea to blue? Easy. Just add aluminum to the soil. Looking to change it back again? Not so easy—you’ll now need to eliminate aluminum from the soil. You can also try adding lime to change blue to pink.
- For more control over your hydrangea color, use large containers to grow them. This way, you can change the soil’s content using amendments, and you won’t be relying on existing soil.
- For more vibrant blue blossoms, make sure you check the pH of the water you’re using to irrigate your hydrangeas. Water with a high pH will reduce the intensity of the blues.
And don’t forget—whatever you do to change the color of your hydrangeas must be maintained if you want to keep it that way!
