I read somewhere that the colour of the flowers is determined by the pH of the soil the plant is in. But that might be nonsense.
👀 Beautiful hydrangeas in different colors. Azores, Portugal 🤙

No, you're absolutely right 🤙.
The flowers of hydrangeas only change color if the soil in their location is acidic enough. And they discolor quickly. Therefore, you should pay attention to the pH value in the soil. The absorption of aluminum ions is responsible for the change in flower color!
