Hydrangea enjoy growing in a part shade location, that provide them with shelter from the hot mid-day sun. Soil should be kept evenly moist as they do no like to dry out between watering. Like all plants water directly to the base on the soil.

Some hydrangea change colour depending on the pH of their soil. To get richer blues amend your soil by raising the pH with aluminum sulfate. For pink blooms lower the pH using dolomitic lime. Soil amendments needs to be done in the fall or early spring before any bud development.
