Saw this thread and had to jump in, because I love growing (and even more so, eating) garlic...
Ken,
Loved the story about the Master Gardeners group!
Alice, maybe you just need to try some different varieties -- like tomatoes, not every variety will do well in all locations.
Linda, if you haven't already, I would recommend trying "Music." Only 4-6 cloves per bulb, but they are big and beautiful and tasty!
