I buy Christopher Ranch garlic and grew it twice. So easy. Just take the cloves and plop them
into the ground or even a pot. Up they come. It takes many months for them to develop, much like onions, so you have to work on that and maybe do two or three plantings a year. It was fun to do, and they were delicious. In summer, I buy from the Farmer's Market. The garlic is so fresh, sticky, and delicious. I have not taken the time to explore how to grow them all year long.
