Hydrangeas grow different colored flowers depending on the pH of the soil.
To make hydrangea flowers turn blue, you can adjust the acidity of the soil by adding aluminum sulfate or other acidifying agents. This helps the plant absorb aluminum, which turns the flowers blue.
Agapanthus colour is normally genetically determined, as such a white flower cannot turn blue. This does happen with flowers such as Hydrangea, where a blue or white flower can be turned pink - this is a result of the pH or acidity level of the soil
You can change the color of a hydrangea plant by adjusting the pH level of the soil. Adding aluminum sulfate to the soil will make the flowers turn blue, while adding lime will make them pink.

You can make pink hydrangeas turn white by adjusting the pH of the soil. Alkaline soil (pH above 7) encourages pink blooms, while acidic soil (pH below 7) promotes white blooms. To turn pink hydrangeas white, you can add aluminum sulfate to lower the pH of the soil.
Not that I've heard. Many hydrangea strains will have different flower colors, depending on the aluminum content of the soil. When there is available aluminum, the flowers will be blue. When there is no available aluminum, they'll be pink. This doesn't work for white hydrangeas. You can add aluminum sulfate, which is available at most garden centers, to turn pink flowers blue. In order to turn blue flowers pink, raise the soil pH by adding a liming material, and the aluminum will form insoluble compounds and no longer be available to the plants.
Hydrangea need acidic soil, below ph6. If the soil is alkaline (ph above 7) then the flowers will turn pink. Don't expect this to happen quickly. It may take an entire season.
you need to change the soil PH, if i remember corectly you need to lower the PH but ask a nursery :)
a lighter blue. pretty much any color mixed with white would turn it lighter.
Blue, no. White, yes.
they will turn blue
Blue food coloring goes into the water. The white rose takes up water in the stem and turns blue.
