How Can The Hues Of Hydrangeas Be Brought Out?

Hydrangeas can change their color due to factors such as sun, water, or nutrients. To change the color of hydrangea flowers, it is essential to know the best time for planting and adjust the soil’s pH levels. A lower pH will turn hydrangeas blue, while a higher pH will make them pink. To make sepals bluer, add aluminum sulfate to soil and maintain low levels of phosphorous, moderate levels of nitrogen, and high levels of potassium. To make sepals pinker, add garden lime to soil and maintain high levels of nitrogen and low levels of phosphorous.

To acidify the soil, add garden sulfur or aluminum sulfate, which can be found at almost any garden center. With a pH between 6 and 7, blooms turn purple or bluish-pink. To lower the pH, add garden sulfur or aluminum sulfate to your soil.

Homemade recipes for changing the pink blooms of a hydrangea to blue include pouring vinegar or lemon juice on the soil, mulching the plant with coffee grounds, and adding lime to the soil. Follow the recommended dose for the product. Blue hydrangeas bloom in acidic soils, usually with a pH of 5.5 or less. The easiest way to acidify your soil and turn hydrangea flowers blue is with aluminum sulfate. By following these simple steps, you can transform your hydrangeas from blue to pink, pink to blue, or both.
