Documentary looking at the extraordinary changes and crazes that have happened to British gardening since the Second World War, from garden gnomes and crazy paving to Leylandii and decking. As recently as the 1960s, garden centres did not exist and gardening was strictly for old boys in sheds, yet today it has become the height of cool. Contributors include Penelope Keith, Laurence Llewellyn Bowen, Germaine Greer and Carol Klein.
