Garlic is IMHO one of the easiest plants to grow. It isn't very picky about when it is planted and you can eat the greens, scapes and bulbs so it produces edibles over a long growing season.
Plant it in the fall in fairly well drained soil. Right now would be a good time if we hadn't just experienced a deluge
Wait a couple of days for your garden to dry out and drop a few cloves in the ground. In the spring, snip the greens to use as chives then let the flowers appear. Snip off all but a couple of scapes to eat. Let the scapes go to seed and use them to replant next year. Don't forget to dig the bulbs after the flower stalks have dried and before they sprout again in the fall.
I've had garlic in my garden for nearly 15 years this way. I use raised beds to improve drainage because our yard soil has a lot of clay. Other than that, I pretty much ignore the plant most of the time. Except for eating it of course.
