Del can probably post the historical aspects of garlic, he'd know it better than I do, I just use the stuff!
I like fresh garlic and use a lot of it. But I had always thought it was something that would only grow in California or something. But one year I was out shopping for my fall flower bulbs at a local shop. It's one of those "Mom and Pop" home gardening stores that's closed on Sundays. (It also carries home brewing supplies) Much to my surprise, they carried garlic bulbs for planting! I had to give it a try.
Growing garlic takes patience more than anything else. It takes well drained soil, and does well in sandy soil. Plant it in the fall (about six inches apart), then wait. It'll send up a shoot, much like an onion, in the fall. Ignore it. The shoot will die back in the winter and disappear. Ignore that, too. That just means the bulb has established itself in the ground and is a good sign. It'll send up a new shoot in the Spring. Kinda ignore that one too, just wait. When the wet of spring is over, start watering the shoot/stalk once in a while, and almost ignore it, but watch it. It might grow to about 3-4 feet tall. ( Don't measure it, that's not ignoring it, that's being impatient!)
When the shoot gets that funny looking, bulb shaped thing on the top of it that kinda looks like something from the Taj Mahal.... still wait, but watch it more closely and keep watering it. When the bulb thing goes into flower, and looks like a pretty, alien starburst, your garlic is ready. When you dig it up, don't dig straight down or you'll bruise the cloves. Dig around it and pop up the bulb, then brush it off. If dirt still clings to it, you can wash it off. Then hang it up until the stalk is dry. Your garlic is ready for use!
If you grow a bunch of it, you can braid the stalks of them together before they dry. Then you can hang it up in your kitchen to impress your Yuppy friends. It likes to be stored in a cool, well ventilated place. The fridge isn't the best place for it because the damp air will fool it into thinking it's been planted and it will try to send shoots.
It's very, very good!
