our limitations will go as far as your imagination takes you and the area of space you have to work the garden. There are raised garden bed kits available for purchase at some nurseries, home and garden centers, or on-line.
They are perfect for the disabled gardener, those suffering from arthritis, and the elderly as they can be elevated to a suitable level so that bending over and kneeling will not be necessary.
These beds do not need the usual distance between each row because you are not going to walk in the bed to cultivate or harvest. Vegetables can be spaced far enough apart to be able to avoid crowding but be close enough to shade out any weeds.
When growing vegetables in raised garden beds using the Square Foot Gardening method, your beds will need to be sectioned off into one-foot sections called planting squares.
