The third title in the CSIRO Gardening Guide series, Sustainable Gardens by Roger Spencer and Rob Cross shows how horticulture can contribute towards a more sustainable future. Written for home gardeners, professional horticulturists, landscapers, and all those passionate about cultivated landscapes, this book examines the steps we can take towards harmonising gardening activity with the cycles of nature. Two outstanding botanists from the Royal Botanical Gardens in Melbourne, Roger and Rob have produced a genuine gardening bible for our times. They show how every gardener – both professional and amateur – can contribute positively to environmental stewardship. Gardens may be consumers of resources, but the negative effects of this consumption can be minimised and can be offset by some of the positive contributions gardens make. Roger and Rob explain the connections between human activity, resource depletion, and environmental degradation. They show how to conduct an audit of gardening practices, materials, and results so that every gardener can measure the impact he or she is having on nature. They show: how to minimise the impacts on nature of our consumption of water, materials and energy in the garden; how to make gardens more environmentally friendly through design, construction and maintenance phases; the importance of biodiversity and how horticulture can help protect natural systems; and the role that gardening can play in alleviating the environmental impacts of food production. Checklists are provided so that gardeners can ensure they are taking the most sustainable path through each phase of gardening – design, construction, maintenance. The book ends with a guide round an existing garden that combines physical beauty with sustainability, and discusses future trends for sustainable horticulture. In an increasingly urbanised world, parks and gardens are our main point of contact with nature. If we can maximise the environmental benefits of our gardens, public spaces and landscapes, we will make a huge contribution to sustainable living. This book if the first to show us how.
