Hello! I went shopping with a friend again (This time not to a garden center or the market lol) And he quickly jump and put in the shopping basket all the organic apple cider vinegar that was on the shelf and mentioned the orchids would love it... Okay, why? I didn't ask him, because honestly I was afraid to accept being ignorant of it at that moment, then I realized it was silly and thought to ask you guys (Still feeling ashamed to ask him lol) So what is it used for? What it does? Or what is it supposed to do? What makes it so special and how does it's PH matter so much?
