Answer: A raised garden generally describes a series of raised beds that accomodate different vegetables and flowers. Raised beds can be made out of brick, fieldstone, or wood, or can simply be made by raking garden soil into broad, flat-topped planting beds. Raised beds are common in northern areas because they help soil drain--and warm up--in the spring. Any type of plant can be grown in a raised bed. One thing to take into consideration is the size of the plant and the depth of the bed--for example, to grow large carrots you'll need a bed with soil deep enough to accomodate those roots. There are several books available about raised-bed planting, and many conventional gardening books have a section about building raised beds; check your locallibrary or bookstore.
