Dolomite Frequently Asked Questions
1. Is Dolomite a good choice for turning hydrangeas pink? Is so, at what rate does one apply it to the soil for it to be effective?
Yes, Dolomite is a great mineral to adjust the pH level of the soil. For hydrangeas to produce pink flowers the pH level should be over 6.0.
You need to know your current pH level to be able to adjust it so it's over 6.0. We have a table on Dolomite detail page that shows how much Dolomite to use to get your desired pH level.
