I have tried many different varieties, mostly soft necks, over the years. One year I tried 6 varieties and a close neighbor tried 6 others. We figured out of 12 we should at least get one or two but we didn't get any worth bothering with. I wonder if our fluctuating temperatures might have a negative effect on it? One week it will be 50 and the next it might be 75 or 85 all winter long. In the past we have occasionally gone swimming in January then we'll have frost the next day. You never know around here. Even though I used ProMix in the raised beds, there is so much salt spray around here that everything gets salty after a while. My friends who live just a few miles inland have no trouble with their garlic.
So garlic is just not my crop. I can grow outstanding tangerines though. LOL
