Pink hydrangeas are the most common. These flowers are predominant because they are watered with clear water. As a result, the soil pH drops and loses its acidity. This happens because of the lime in the water. Increase the pH by adding calcium nitrate or sawdust, and you will get pink flowers. Be careful, this technique is a one-time use only. Flowering plants need acidic soil to grow healthily. Prolonged treatments to vary flower colors that increase or decrease the acidity level can damage the plant over time.
