Flower Color<br />

Only bigleaf hydrangea<br />

and mountain hydrangea<br />

blooms are affected<br />

by soil pH. The flowers<br />

of other hydrangeas<br />

will not change color.<br />

Blue flowers appear in<br />

more acidic soils, where<br />

aluminum is more<br />

available to the plant.<br />

In more basic soils,<br />

where aluminum is less<br />

available, the flowers will<br />

be more pink. Blooms can<br />

range from deep blue to<br />

purple to hot pink, with<br />

different varieties having<br />

a tendency to be either<br />

more pink or more blue.<br />

You can adjust the color<br />

of the blooms by adding<br />

aluminum sulfate to the<br />

soil for more blue flowers<br />

and lime to soils to<br />

encourage pink blooms.<br />

It may take a couple<br />

of seasons to see the<br />

desired color.<br />
