Blue Hydrangea Flowers

The color of some Hydrangeas flowers is influenced by the acidity of the soil, acid soils produce bluer flowers than alkaline soils.

However SOME hydrangeas will not turn blue at all, pink and blue Hydranges can generally be changed, however white hydrangeas in general 'stay white'.

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.


Hydrangea are pruned according to the flowering habit, some flower on new growth, some on old growth. So look at the individual species for pruning instructions.
