Change The Color of Hydrangeas By + or –
To change the color of hydrangeas it is a matter of adding or subtracting minerals that occur naturally in your current growing soil.

It certainly helps to have a Soil Tester – Moisture, Light & pH tester.

Pink to Blue
If your hydrangeas flowers are currently pink and you wish to make them a beautiful hue of blue you will need to change the ground soil composition. Acidic soil contains higher aluminum contents, which are needed to have blue hydrangea flowers.
Directions:
STEP 1 – Water the bush well. Mix up 1 tablespoon of Aluminum Sulfate per gallon of water.
STEP 2 – In order for your flowers to maintain that beautiful hue of blue, feed your bush a steady diet of aluminum sulfate throughout the growing season. The bush will benefit from coffee grounds and grass clipping additions to the top of the soil to help maintain the coloring between aluminum sulfate additions.
Blue to Pink
If your bush is naturally blue in color, you will need to block the plant from leaching aluminum from the soil. The soil of pink hydrangea have an alkaline base, The only way I have heard to do this is to add Dolomite Lime many times a year. This will change the PH level of the soil.
Directions:
STEP 1 – Water the bush well in the morning.
STEP 2 – In the evening work 1-2 cups of dolomitic into the soil a few times a growing season.
