Turn and loosen the soil with a garden spade in your chosen planting area to a depth of 6 inches in late August. Spread a 2-inch layer of aged compost followed by 3 lbs. of 10-10-10 (nitrogen-potassium-phosphorus) fertilizer per 100 square feet of planting area with a garden rake. Turn the soil again, to a depth of 6 inches.
Separate the garlic bulb into individual cloves (use only the largest cloves for planting). Dig a hole for each clove that is 3 inches deep. Plant one clove per hole, pointy end up. Space each hole 4 inches apart in a straight row. Space rows 1 foot apart.
Water the planting bed with a gentle spray of water until the soil is moist to a depth of 6 inches. After the first watering, the bed will need 1 inch of water per week if the rain does not provide it. At no point should the soil become completely dry.
