Did you know: Hydrangea Chemistry

These beautiful big balls of flowers can be seen in an array of colors from June-Sept.  But did you know that you can control their flower color!

 
Hydrangeas can go from Deep Blue to Hot Pink just by changing the pH of the soil. It may take a matter of months, but it can be achieved with soil amendments. A sulfur or nitrogen based amendment such as Holly-tone will lower the number; acidic=  blue blooms.  A limestone based amendment like Plant-tone will raise the number and make the soil more alkaline resulting in pink blooms.*It is important to get a soil test before you begin treatment and make sure surrounding plant material can handle the pH adjustment.
