Hydrangeas
are hardy in zones five through nine. When growing hydrangeas,
it is important to note that the plants should not be pruned
back very far in the winter, as they will bloom on older wood
stems. The easiest way to propagate hydrangeas in a garden
is by division. Dividing one larger plant into several small
plants should be done every few years or so, to ensure that
the plants get enough room to grow.
The most important thing to note when growing hydrangeas is
the ability some have to change bloom color based on the pH
level of the soil. The bloom will be blue in more acidic soil,
and a lovely pink in soil that has a higher alkaline content.
Adding lime will make the flowers pink, while adding aluminum
sulfate will turn the blooms blue.
