Fall is the best season to plant garlic, according to Good Housekeeping. Planting garlic in the spring results in a less bountiful harvest, notes The Old Farmer's Almanac. It is best to plant garlic approximately 30 days before the ground freezes.
Planting in the fall gives the bulbs a chance to grow larger, and it also increases the flavor of the bulbs, according to The Old Farmer's Almanac. Good Housekeeping recommends planting bulbs in loose soil 6 to 8 inches apart about 2 inches deep with the roots facing down, although the Old Farmer's Almanac suggests planting bulbs as close as 4 inches apart.
