Hydrangea bloom not coloring
 

"Elaine" expounded:


Yes Ann theoretically 7 is neutral. In this discussion however, if you will
read from the beginning, is in regards to the proper pH for the color of
hydrangeas. 7 is the proper pH for pink and is considered alkaline enough to
produce that color. See the link I provided on the subject.

What Stephen said. Not encouraging a misconception is all that's
being avoided here.
