Hydrangeas are tremendously popular shrubs for their spectacular blooms, with large floral heads of bright blue, pink and white colors. However, they are also known because it is possible to change the color of their flowers, so that we can choose what colors we want each plant to adopt. Doing it is not as simple as it seems, but with a few tricks it is available to everyone.If you want to know how you can change the color of hydrangea flowers to vary between blue hydrangeas, white hydrangeas, pink hydrangeas and even get in some cases an intense tone that reaches red or maroon, keep reading us in this Green Ecology article that shows a guide on how to change the color of hydrangeas.
Is it possible to change the color of a hydrangea?
As we have just said, it is possible to change the color of the flowers. The color of hydrangea flowers depends on the bracts that the plant produces around the true, much smaller flowers, and the color of these bracts does not depend on anything other than the pH of the soil, that is, its level of acidity or alkalinity.
Hydrangeas are plants that usually prefer acidic soils, but can develop in a wide range of pH ranging approximately from 4.0 to 8.0, giving rise to different colors in these ranges.
In addition, it is important to note that experiments changing the pH of the soil should be carried out at least 60 days before flowering and that any subsequent changes will no longer have the desired effect on the plant.If there is a case of loss of color in hydrangeas, it is most likely that they need more nutrients or that the pH is changing. Additionally, different varieties of hydrangeas have different natural colors. Although it is possible to modify these colors by altering the pH of the soil, the ideal will be to provide them with an acidic soil, which is also the best way to enhance the color of hydrangeas.
