Question

How do I change the color of my hydrangea?

Additional Details

I have bought many Hydrangeas from Mahoney’s. I have a blue mophead hydrangea next to a white hydrangea. I have put the Aluminum Sulfate on the opposite end of the blue hydrangea from the white one. The white hydrangea is now blue. Do I add lime to make it go back to the white color. Thank you.

Answer

Yes lime will bring back the white color. It may be better to use a holly tone on the blue in the early spring and do it at half the dose so that there is a less of a chance it leaches to the white one. If they are that close you may have a balancing act every year or so.
