"John Walker is asking the sort of questions you don't usually find asked in gardening magazines." A celebrity gardener's 'wobble' over climate chaos... the effect genetically modified crops might have on our gardens and allotments... how adopting a vegan-organic approach can make growing more compassionate... why pesticides must be consigned to the history books. In this diverse, lively and thought-provoking collection of essays about gardening and its relationship with nature, John Walker digs deep into gardening's subsoil to challenge assumptions, raise awareness and encourage us to ponder how what we do on our plots affects our shared living world. This first book of John's earth-friendly garden writing, originally published in magazine as his popular and long-running series 'Digging Deep', includes 'Time to power down?', which won the Garden Media Guild Environmental Award in 2007.
