| The color of Hydrangeas flowers is influenced by the acidity of the soil, acid soils produce bluer flowers than alkaline soils.
So in general a low ph will produce bluer flowers in most Hydrangeas than a high ph.
Planting Hydrangeas near concrete structures where lime leaches into the soil makes blue flowers difficult to obtain, in other areas soil acidity can be altered more easily.
Blue Hydrangea Flower
Hydrangea plants grow well in a part shaded position with protection from hot afternoon sun. They prefer a humus rich moist soil and need protection from frosts. |
