You can grow garlic shoots using little more than fresh garlic from the supermarket. Simply let it sprout and nurture it until you can harvest the green shoots.
You can't grow garlic bulbs indoors, since they require six weeks of a winter cold cycle for growth, but the more subtle-tasting shoots can be conveniently grown in your home.
Both softneck and hardneck garlic varieties thrive indoors. Wait for the bulb to sprout, then plant the sprouting cloves in a 6-inch container, keeping the outer skin intact.
Point the green tip up out of the soil and ensure that the cloves are not touching. Place the container in a sunny spot with well-drained soil, and water gently twice a week.
Position the pot near a south or west-facing window for at least 6 hours of indirect sunlight per day. In about two weeks, green chive-like shoots will emerge from the plant.
Harvest the shoots once they reach 3 inches, leaving a 1-inch shoot attached to the plant to ensure regrowth. If new shoots stop forming, simply repeat the planting cycle.
