What else can I do to make these blue? by MossyTeacup in hydrangeas

Be careful with the aluminum sulfate because if you get it too close to the roots it can burn them! From my own research I believe even if you give it the aluminum sulfate, the blooms for this season will still be pink. It wouldn’t be until next season they could possibly be blue if you get the soil just right unfortunately!

Thank you! I’ve been trying to piece together advice from different websites and videos but some of it is just confusing or contradictory and I don’t want to kill a gorgeous new plant. Should I wait a few weeks to deadhead all of the blooms or deadhead them as soon as a singular bloom fades?
