Although garlic plants do flower, they don't produce fertile seeds, so propagation of garlic comes only from splitting up a bulb–separating the cloves–immediately before planting.
Plant each clove 1/2- to 1-inch deep and about 3 to 5 inches apart in rows that are 18 to 30 inches apart.
Garlic cloves should be exposed to temperatures of below 50 degrees F before planting in order to sprout.
