Garlic
With a ton of culinary uses and only a little growing space required, garlic in the garden is a must have. Plant individual cloves base down in fall. Cut the scapes, or seed stalks, in the summer for use in sautés and stir fries. Harvest cloves once the leaves have begun to brown and wither, then spread in a warm, airy place for a few days to dry out. Store in a cool, dark place through winter.
Onions and Leeks
Among the benefits of growing onions and leeks is the fact that they remain relatively free of disease and pests and requrie little maintenance once planted. There are many different types of onions, so choose the varieties that makes the most sense for your style of cooking. Onions take up little space, so this leaves you with room to try a few varieties each season.
Onions and leeks can quite happily be grown in a container, just keep the soil moist and weed free, have good drainage, and leave them in a relatively sunny spot.
