Why not start with a small amount and replant all or almost all of next year’s harvest? My neighbor’s starting me on some garlic this fall. He grows around 750 bulbs every year and started with just three bulbs. He doesn’t know the name of the variety but he was told when someone else started him on this that it originated in Australia. It’s a mild, and I believe porcelain, type that lasts stored in a basement all the way through the next year’s harvest. I’m also thinking about buying something stronger, leaning towards either/both of Spanish Roja and Music.
