I covered an area in the lawn with a layer of four pages of black and white newspaper. I used the soil from one of my potato bags, dumping it over the newspaper. Then I buried cloves from two bulbs of different varieties of garlic (one mild, one spicy hot). The cloves were planted about 6 inches deep. Next I'll put a layer of mulch over the soil.
Garlic is one of the easiest plants to grow. In this New England area, I put the cloves in the ground at the beginning of Fall and harvest in mid July. Just take a square foot of lawn and turn it into a garlic garden.
