The Science We Got Wrong: How Plant Research Rewrote the Rules for Gardening - Ep. 311

What's in this episode

For most of the last century, gardeners were taught to cultivate their soil after every rain to conserve moisture, to think of plant roots as lone competitors, and to treat "plant communication" as science fiction. All of that was built on the best evidence available at the time, and all of it has been revised, in some cases more than once, as better tools let researchers see what earlier generations simply could not. In this episode, we walk through four real case studies of plant science changing its mind. Along the way, we talk about how the scientific method works, why one of my favorite phrases, "we don't know what we don't know," is not a discouraging idea but an exciting one, and what all of this means for the choices you make in your own garden each season, now and into the future.
