| I've read the Q and A section to see if you had a suggestion on how to keep a "white" Hydrangea white. There are ways to keep "blue" blue and "pink" pink but how do you keep "white" blooms white? |
| To my knowledge there is no way to whiten the blooms of white hydrangeas. Most of them, such as Hydangea arborescens "Annabelle" are a clean white with a tinge of green and then age to a dusty pink and finally golden brown. This is their normal coloration and aging process is not affected by pH. |
