Garlic is a member of the allium family which also includes leeks, shallots and onions. Individual cloves act as seeds. The bulbs grow underground and the leaves shoot in to the air. Although garlic is traditionally thought of as a Mediterranean ingredient garlic is also grown successfully in colder more Northern climates. Garlic is grown from the individual cloves. Each clove will produce one plant with a single bulb - which may in turn contain up to twenty cloves. Growing garlic is therefore self-sustaining.
When planting garlic, choose a garden site that gets plenty of sun and where the soil is not too damp. The cloves should be planted individually, upright and about an inch (25 mm) under the surface. Plant the cloves about 4 inches (100 mm) apart. Rows should be about 18 inches (450 mm) apart.
