In this first episode of a two-part special from The Underground Podcast, hosts Kate and Phil dig into the root of the industry’s biggest environmental pivot—going peat free. 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. Episode 2 will pick up the trail, delving into the practical realities of making peat-free work.Featuring:Elaine Gotts – Research & Development Scientist, Levington / Evergreen Garden CareSimon Blackhurst – Horticulture ConsultantWill Scott – Team Leader, Heart of Eden (AHS Limited)Jane Hartley – Brand Portfolio Manager, Evergreen Garden CareSteve Harper – Chair, Responsible Sourcing Scheme & Managing Director, Southern TridentSally Nex – Environmental Gardener & Campaigner, Peat-Free PartnershipFran Barnes – Chief Executive, Horticultural Trades AssociationJane Lawler – Marketing Consultant & HTA Board MemberDan Durston – National Sales Director, Durston’sToby Thomas – Managing Director, RocketGro
