Changing the Color of Your Hydrangeas
Note: If you have alkaline soil, you will have pink blossoms on your Endless Summer Hydrangeas. If your soil is acidic, your blossoms will be blue. To alter your flower colour you may use the products described in this video or use aluminum sulfate as described on the package to alter the colour, turning it blue. Lime will turn the bloom pink. If your soil is in between acidic and alkaline, you will likely have mauve blossoms. Keep in mind, it takes about 1 year before any soil additives will take effect on the bloom colour. Remember, more is not better! Follow directions on your product to prevent damage to your plant.
