With decades of dependency on this “gold standard” of growing media, why is it now so crucial to leave peat behind? And why is it proving so hard to replace?From the carbon cost of extraction to the slow regeneration of peatlands, this episode explores the environmental urgency driving the move away from peat. But this is no simple switch. Through conversations with leading scientists, manufacturers, campaigners, and trade leaders, we uncover what made peat so effective—and why sustainable alternatives must work harder to match its performance.Whether you’re a professional grower, a home gardener, or simply peat-curious, this episode lays the groundwork for understanding what’s at stake and what’s next in this growing media revolution.
