Changing the colour of hydrangeas

Over the summer months, we have been seeing a beautiful display of hydrangeas.  Have you ever wondered why the colour variation?  Hydrangeas will flower pink in alkaline soil to blue in acid soil.  It is possible to change the colour of your hydrangeas.  Adding organic matters will turn soils more acid and you can neutralise acid soils with the addition of lime.  Cream/white hydrangeas remain that colour.
