Make Hydrangea Flowers Blue

Greg tells us How To Make Hydrangea Flowers Blue in this video blog.

Hydrangea macrophylla or big leaf hydrangeas have large round blooms that range in color from blue to pink.  This color in large part is due to the pH of the soil.  You can adjust soil pH by using different soil amendments.

  • Use a Soil Acidifier to lower the pH and make Hydrangea Flowers Blue.
  • Use Lime to raise the pH to make Hydrangeas bloom Pink.
