him: Did you know that hydrangeas are the litmus plant of the botanical world? If your blue hydrangeas are blooming pink, or your pinks are purple, you may want to adjust the pH of your soil to get the desired color. Acidic soils turn hydrangeas purple and blue. Alkaline soils leave hydrangeas pink. What you should know is that you can't turn an already pink hydrangea blossom blue or the other way around. But you can make a difference now while the flower buds are forming for next year.
