Wait until the first frost of the season to plant individual cloves of garlic in a sunny location with well-draining, nutrient-rich soil. Cover the garlic with a 4-inch thick layer of mulch, and allow the garlic to remain undisturbed over winter. In the spring, add a new layer of mulch, and water the garlic regularly until midsummer. After midsummer, stop watering the garlic. Harvest the garlic when the stems begin to turn brown.
To prepare the garden for planting garlic, loosen the top 12 inches of soil, and work a 1-inch layer of compost into the soil. If soil tests indicate acidic soil, amend it before planting. Plant the cloves of garlic at a depth of 4 inches, and space the cloves 6 to 8 inches apart.
In spring, move the mulch away from the base of the plants if the green shoots are unable to grow through the mulch. To harvest the garlic, wait until the bottom leaves are brown, and dig the bulbs out of the soil carefully.
Allow the garlic to dry in a warm, protected location with good air flow for one week. After one week, clip the roots to 1 inch, and brush the soil off the bulb. Store the garlic in a cool, dry place for up to 6 months.
