How to change colors?
The color of hydrangeas is a spectacle in itself and one of the factors that most enchants lovers of this plant. Interestingly, the color of the hydrangea can be manipulated by changing the pH of the soil, making it possible to obtain flowers in shades of pink, blue and even purple. Here's a simple guide on how to do that:
- Understanding Soil pH: Blue hydrangeas grow in soils with an acidic pH (below 7), while pink hydrangeas prefer an alkaline or neutral pH (above 7). If the soil pH is between 6 and 7, the flowers can be purple or a mixture of blue and pink.
- Testing soil pH: Before trying to change the color of your hydrangeas, it's important to know the current soil pH. You can buy a pH test kit at a garden supply store or have a professional soil test done.
- Changing the pH of the soil: If you want blue hydrangeas, you must make the soil more acidic. This can be done by adding materials such as aluminum or iron sulfate. For pink hydrangeas, the soil should be more alkaline. In this case, add dolomitic lime or limestone to the soil.
- Patience and maintenance: Changing soil pH is a gradual process that can take several weeks or months. You will need to regularly monitor your soil pH and adjust the amount of material you are adding as needed. Remember that too much of any additive can be harmful to plants, so it's important not to overdo it.
- Additional considerations: In addition to soil pH, other factors can influence the color of hydrangeas. Some hydrangea varieties are genetically predisposed to bloom in certain colors, and environmental factors such as soil health and water availability can also have an impact.
