Our gardens are guzzling between one quarter and one half of all domestic water. With our very dry land, where fresh water is a relative trickle, we need to get waterwise... and fast! Waterwise Gardening sets out the six vital principles by which we can have a beautiful garden and save water, too. It describes over 200 drought-tolerant trees, shrubs, groundcovers, perennials and bulbs, and discusses their needs and features. Full of information on waterwise design, the power of mulch, the pros and cons of various watering systems and products, this third edition is a complete revision of Kevin Walsh's pioneering book, Watersaving Gardening.
