Episode Details

We made it to 300 episodes! And to celebrate, I’m doing something a little different. I went looking for the questions home gardeners are asking most, the ones showing up in Reddit threads, Facebook groups, university extension Q&A lines, master gardener helplines, and my own DMs and emails, over and over and over again. Then I went to the research: university extensions, peer-reviewed horticulture studies, and land-grant university publications, to find the best science-backed answers available. The result is this episode, ten of the most common gardening questions, answered with evidence, nuance, and a little bit of real-world gardener perspective from someone who’s been doing it for over 20 years and with a degree in horticulture. Whether you’ve been listening since episode 1 or you just found me today, this one is for you.

Let’s dig in.
