Market Gardening, in its broadest sense, is the growing of vegetables for commercial purposes, but the generally, accepted meaning is that market gardening relates to the intensive culture of crops that may be planted close together, that mature quickly and that offer great financial possibilities for the area cultivated. The most popular crops in market gardening are beets, onions, celery, lettuce, radishes, carrots and other vegetables which are usually cultivated with wheel hoes. Market gardens are generally located near cities, which provide good local markets. Land so situated is usually of high value and it is necessary for the grower to secure maximum returns from every square foot of ground.
