Question
We just purchased Endless Summer Summer Crush. We want the blooms to be the color shown on the tag. The color range indicator shows the more acidic the soil, the darker the blooms while the more alkaline the soil, the lighter the blooms. What should the soil PH level be to get the color shown on the tag?
Answer
There’s actually fascinating science behind hydrangea flower colors. Take a look at my soil science video to learn tips on how to adjust the color. For best results, you will need to wait until spring next year.
