Question the claims you hear about plants – including the ones you already believe. Test as much as possible through your own personal, lived experience.
People have mystified, commercialised and simplified plant knowledge into a generic blur.
The habit of finding out for yourself ensures one’s plant knowledge is real. It comes from your own experiences, not theory or hearsay.
What belief about the living world have you held onto without checking it directly? What would it feel like if you didn’t have an answer for everything?
