Methods For Naturally Turning Hydrangeas Purple?

To make hydrangeas purple, follow this step-by-step guide. Ensure you have a hydrangea variety known for its ability to change color. Next, learn how to use vinegar to turn your hydrangeas blue and other methods to help them achieve the perfect hue. Soil pH plays a critical role in hydrangea coloration, and adjusting it can help achieve the perfect shade. Acidic soil (pH 5.5 or lower) produces blue or purple flowers, while neutral to alkaline soil (pH 6.5 or higher) produces pink or red flowers.

To naturally turn your hydrangeas purple, adjust soil pH, add aluminum, amend soil, prune, mulch, fertilize, and more. Acidic soil, with a pH lower than 6.0, yields blue or lavender-blue hydrangea blooms. Alkaline soil, with a pH above 7.0, promotes pinks and reds. With a pH between 6 and 7, the blooms turn purple or bluish-pink. To lower your pH, add garden sulfur or aluminum sulfate to your soil.

To make hydrangea flowers turn purple, gardeners need to bring the pH levels of their soil to a slightly acidic level between 5.0 and 6.0. If you want to turn your hydrangea flowers purple, you can change the pH of your soil over 1 to 2 growing seasons and slowly watch your flowers change.

For hydrangeas to turn purple, aim for a soil pH of 6.5 – 6.8. Regular watering, a partly shaded spot, and careful attention to the acidity of your soil can help boost your hydrangea blooms to bold blue or pretty pink.
