Sarah speaks to the Earth Friendly Gardener, John Walker about the use of peat in our gardens.  We all know it's bad, but how bad is it and what's being done to prevent the use of peat in horticultural products? Is it realistic to think we can eradicate our use of peat? John is one of the foremost experts on this topic and it's fascinating to hear his thoughts. Sobering stuff indeed... About John:  “As well as being a lifelong gardener and allotmenteer, I’m also an award-winning British gardening and environment writer with over 30 years combined experience in professional gardening, horticultural teaching and the garden media. I trained as a student gardener at the Birmingham Botanical Gardens & Glasshouses, Cambridge University Botanic Garden, and at the Royal Botanic Gardens Kew, England, where I was awarded the Kew Diploma in Horticulture in 1986. I gained a Permaculture Design Certificate in 1997. While in publishing, I’ve been both features and deputy editor of Garden Answers magazine, contributing editor of Kitchen Garden magazine, and have been technical editor of The Organic Way. My long-running ‘digging deeper’ column, exploring the connections between gardening and our wider environment first appeared in Organic Gardening (later Organic Garden & Home) magazine in 2006. I write and blog about greener, earth-friendly gardening for national newspapers, magazines and websites. My work has been published in NFU Countryside, Garden Answers, Garden News, Grow It!, Kew magazine, Organic Gardening (later Organic Garden & Home), the Telegraph, The Garden, The Organic Way and Kitchen Garden, and online at the Guardian and Hartley Botanic. I’m the author of the new and updated Weeds: An Organic, Earth-Friendly Guide to Their Identification, Use and Control and The Bed & Border Planner, the editor of A Gardeners’ Guide to Annuals, and a major contributor to the Garden Organic Encyclopedia of Organic Gardening.” John’s website is a treasure trove of articles and information, please do check it out: http://earthfriendlygardener.net  You can buy a signed copy of John's latest book, Weeds: An Organic, Earth-friendly Guide to Their Identification, Use and Control' here    Get in touch; Email podcast@rootsandall.co.uk  Website www.rootsandall.co.uk  Twitter @rootsandall Instagram rootsandallpod   Patreon Link; Help us keep the podcast free & independent!
