Home-based water conservation starts with this book, the only North America-wide guide on how to convert your yard from a water-sucking source of pollution runoff to a flourishing, productive showcase of natural vegetation. While 1.3 billion people on the planet don't have access to safe drinking water, 60 per cent of ours goes into conventional turf-grass lawns and ornamental, exotic gardens. Runoff from chemical treatment of lawns and gardens has seriously compromised groundwater supplies everywhere in the United States and Canada. The book teaches how to conserve water and prevent the pollution of groundwater. It covers how to cut, roll up and compost turf-grass lawn (and water-sucking, ornamental 'exotic' garden plants) and how to replace them with gorgeous native ground covers: flowers, shrubs, trees and grasses that will need no fertilisers, no chemical controls for pests, no mowing and, after the first year, no watering.
