How much garlic you should grow? How much space do you need? Mulch? Till? Tools? How do you build beds? A few practical things about answering these important garlic-planting questions and preparing ground, particularly under less-than-ideal conditions.
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.
