Since we’ve been at this podcasting game for more than two years now, we figured it was time we asked you guys—our loyal listeners—what pressing plant questions you have. We got questions about design and Zone 4 recommendations, and one brave listener even wrote in to ask about our favorite PINK plants (yikes!). There were a handful of questions that left us clueless, so we called in a few bona fide experts to help out. After all, if there’s one thing we have figured out through the course of this show, it’s that we don’t know it all—even you, Steve.
