Renewable Gardening

John Walker is an award-winning gardening and environment writer and author. His latest book is The Vegan Gardener: Using Vegan-organic Techniques for a Planet-friendly, Wildlife-abundant, Beautiful and Productive Garden. Despite occasional squirrel-fuelled frustration, John is enjoying eking a wild-spirited earth- and climate-friendly garden from a once bracken-riddled hillside at his home in Eryri (Snowdonia), North Wales. His large lean-to greenhouse is powered by free, non-polluting and renewable modern sunshine. All views expressed are those of the author and not necessarily those of Hartley-Botanic.co.uk
