Newcomb trimmed Alan Chadwick's intensive methods for The Postage Stamp Garden Book (1975); this new book streamlines the process even more, and insists that even a 5-by-5-foot plot can feed a family, especially if everyone pitches in. Advance planning is important, large amounts of organic additives are crucial, and assorted contraptions extend the growing seasons for many crops. The financial investment can be minimal, especially if you're willing to use old cans and containers ""creatively,"" and caretaking time can be limited. Easygoing and resourceful (one protector consists of newspapers and stones), this recycles some familiar ideas into new shapes and friendly idioms. If you're game for vertical gardening with cages and A-frames, or for trying out midget varieties in unused wagons or bookcases (""Vegetables without a Garden""), here's your starter.
