Why do hydrangeas change color ?

Hydrangeas change color due to the pH of the soil. Hydrangeas are able to take up aluminium from acidic soils and this affects the color of their flowers. The more acidic the soil is, the bluer your hydrangea will be. Conversely, alkaline soils produce pinker blooms.
If you want to make your hydrangeas blue, there are several things you can do. Firstly, test the pH of your soil with a testing kit and adjust it accordingly. If you want to increase acidity, add sulfur or iron sulfate to the soil. Alternatively, if you need to reduce acidity, add agricultural lime or wood ash. Secondly, you can also use special fertilisers or additives created specifically to turn hydrangeas blue. Lastly, there are varieties of hydrangea that are naturally blue – so if you’re looking for a guaranteed way to bring out the deep blues and purples, these could be worth considering.
