Want to grow more food in less space with less effort? The “All New Square Foot Gardening” by Mel Bartholomew has the approach you might be looking for. With gas headed skyward, putting away the tiller and growing what you need makes a lot of sense. 100% of the harvest at 50% of the costs, 20% of the space, 10% of the water, 5% of the seeds, and 2% of the work – that makes it a no-brainer.
