ABOUT THIS EPISODE
Earthworms are supposed to be a sign of healthy soil. But they're actually an invasive species that can even damage forests. So have we been sold a lie about worms and soil? Not exactly. The relationship between the two depends on the context. And the way we garden — or farm — can make all the difference. IDEAS producer Annie Bender unearths the complicated truth about the not-so lowly earthworm.
