If you don't use raised beds you might consider some just for garlic. You can amend the soil to the kind you want.
Sorry to quote myself, but. I just watched a CBS report on food prices going up. Consider how much garlic you use each year. 10 - 15 lbs maybe? Now do the math. Garlic is easy to grow and easy to store. If you only grew garlic, how much would you shave off your grocery bill? I just checked Wegmans. $3.99 a lb. We use a lot of garlic in this house. So that's $40 - 60 a year. That's a lot of chicken feed. Plus garlic is low or no maintenance. Plant it and forget it til harvest time.
Correct me if I'm wrong but a 4' X 4' bed with garlic planted 5" apart is 92. bulbs. If the average bulb weighs between 1 - 2 ounces that's 5 - 10 lbs just in that one bed. Approx.
92 @ 1 ounce ea. / 16 ounces + 5.75 lbs. X $3.99 = $22.94. That's at the bottom end of course. You may do better, but even if you do the lowest size your still saving for little effort.
