The
first part of hydrangea plant care is pruning. When pruning
the plant in the winter, any stems that flowers the previous
season should be pruned back. Unflowered stems should not
be pruned, as these will provide the flowers for the next
year. Any dead stems or weak parts of the plant should also
be pruned back at this time.
The most
interesting part of hydrangea plant care is the ability to
change the color of the blooms, simply by changing the pH
level of the soil. If the blooms are blue, adding some lime
to decrease the acidity of the soil will change the flowers
to pink. Pink blooms can be turned blue by adding aluminum
sulfate. Hydrangeas use a lot of water, and should be watered
regularly during times of drought.
