I heard Felder Rushing say on Friday's radio program that you should plant it in October and plan to harvest the bulbs next spring. He said if a flower stem comes up, to break it off so the plant's energy will be forced into the bulbs. You can just buy a bulb of garlic at the grocery, break it apart, and plant the cloves.

I planted some this way back in the spring. The greens were pretty and very delicious in salads and stir fries, but, of course, when our heat moved in, it quit.

I am going to try again this fall.

I don't have garlic now, but planted it several years ago. You can find several varieties available using a google search.
I always planted mine around Thanksgiving and harvested it the next spring.

Since I only have a small area to dedicate to garlic I guess I'll see what I can find locally.
