I apologize if this has been asked before, but I never saw the topic.
Are
there any household potions I can add to my potted hydrangea to make the
blossoms blue? Or do I have to buy some commercial product, and if so
what
is it? Thanks


Try aluminum sulfate. If that doesn't work, kill your pet dog and bury
his/her body next to the roots.
Aluminum sulfate will acidify the soil so I guess acid is blue and basic is
pink. You can use a very dilute solution of vinegar or azela food but much
weaker than the directions say.
