Book excerpt: Are you facing drought or water shortages? Gardening with Less Water offers simple, inexpensive, low-tech techniques for watering your garden much more efficiently — using up to 90 percent less water for the same results. With illustrated step-by-step instructions, David Bainbridge shows you how to install buried clay pots and pipes, wicking systems, and other porous containers that deliver water directly to a plant’s roots with little to no evaporation. These systems are available at hardware stores and garden centers; are easy to set up and use; and work for garden beds, container gardens, and trees.
