Garlic is wonderful, and part of the wonderfulness is, it's pretty easy to grow. The main difference from many other crops is, this is one to plant now, in the fall, and to winter over.
Fall planted garlic builds a strong root system, and when spring rolls around and the ground warms again, it kicks into a growth spurt, well ahead of spring planted cloves. (Still, if time got away from you, or your cloves arrived late, spring planted cloves will grow. You'll get a more modest crop, but even a modest crop of garlic is something good to have.)
