Select your soil site. Garlic prefers fertile, loamy soils in a sunny location. Fertilize the soil with 3 lbs. of 10-10-10 or 10-20-10 fertilizer for every 100 square feet, and supplement clay soils with organic matter for increased drainage.
Pick your garlic clove for planting. Separate the clove immediately before planting for optimal growth. Large outer cloves tend to produce the highest-quality plants.
Place the garlic clove upright in the soil, with the skinny side facing upward. Cover it with 1/2 inch to 1 inch of soil. If you are planting multiple rows, space the cloves 4 to 5 inches apart and the rows 12 to 30 inches apart.
Water the garlic bulbs frequently until they are established. Continue to keep soil moist, but avoid overwatering to prevent bulb rot. When the plant is mature, let the soil dry out between waterings.
Harvest garlic when the tops begin to dry and turn yellow or brown. This usually happens in late summer. Most garlic varieties mature within eight months of planting.
