After another summer of droughts and heavy downpours, there is no avoiding the fact that we need to think differently about water. Unlimited water on tap is no longer something we can take for granted, and as climate change escalates, neither is moderate, adequate rainfall. Meanwhile, our demand for mains water is increasing exponentially. The fact that we cannot garden without water does not mean that we have the right to go on gardening as we have always done, regardless of the demands our plants are making on the planet's resources. The good news is that it is entirely possible to have a lush, thriving garden that is independent of mains water, and this introductory guide shows you how. It explains the ecological, financial and practical reasons for gardening in a more waterwise way, and goes on to explore the different ways in which this can be achieved. Creating a waterwise garden is a three-part process.
The first step is to design your garden in waterwise ways, the second is to employ water-efficient gardening techniques, and the third is to supply as much of possible of its remaining requirements from recycled sources, by harvesting rainwater and reusing household 'grey' water. This book addresses each of these areas in turn, exploring the many different aspects of water use and water saving in the garden. It considers the relevant aspects of garden design, explains the concept of 'hydrozones', and looks at water-saving measures relating specifically to planted areas, grassed areas, paved areas, green roofs and containers. It goes on to demonstrate how techniques including soil improvement, mulching and efficient watering can reduce your garden's water needs. Finally, it explores the many options for rainwater harvesting and storage, from water butts to water tanks to ponds and pools, and the possibilities of reusing and purifying household 'grey' water. The book concludes with a detailed further reading list.
