If you would like to harvest some fresh delicious garlic in the summer, how about taking the friends or family outside this Thanksgiving and following these easy instructions from the University of Georgia:
Garlic does not produce true seed but is propagated by planting cloves, which are the small bulblets or segments making up the garlic bulb. Each bulb usually contains a dozen or more cloves; each clove is planted separately. Select only larger outer cloves of the best garlic bulbs for planting. The larger cloves yield larger size, mature bulbs at harvest. Do not divide the bulb until ready to plant; early separation decreases yields. Select "seed bulbs" that are large, smooth, fresh, and free from disease.
To plant garlic properly, dig a hole or trench, place the unpeeled clove gently into the hole with the pointed side up (the scar [stem] end down) and cover the clove with soil. Setting the cloves in an upright position ensures a straight neck. Approximately 2-3 pounds of garlic bulbs will plant 100 feet of row. The amount will vary depending on variety (number of cloves per pound), row width, and plant spacing.
Plant cloves 1-3" deep and 6" apart. Rows are usually planted 12-14" apart. In colder areas of the state, cloves may be planted slightly deeper for winter protection. Mulching will help protect bulbs from severe cold and will help conserve moisture. Irrigate immediately after planting.
