There is much talk surrounding urban gardens and their potential benefits to habitat, water conservation, minimizing the heat island effect, and so on. Some of these said benefits are grounded in research, while some are not. There is something to be said for not caring whether every element of one’s garden has withstood the microscope of scientific inquiry, as it is a garden after all, and it is supposed to provide space and time for relaxation and enjoyment and not always a forum for cerebral head-scratching. In any case, if we are to make claims that an urban garden can and does achieve a whole host of goals pertaining to sustainability, a bit of science to back them up would serve the cause well. Enter the Royal Horticultural Society (RHS) and their new endeavor to create a peer-reviewed guide to urban gardening that offers current gardeners and potential new ones advice rooted in real research and literature on what you can do and not do to ensure that your garden is a true beacon of green goodness and not simply one that has the veneer of being green. This effort to create outdoor spaces that are truly sustainable as opposed to ones that merely present a veneer of sustainability is something we strive to do in all of our work, so this report we could not be more excited about. The initial summary is available to read on their website, with the full, peer-reviewed report to come out in fall. Happy reading, everyone.
