bed gardening is a form of gardening in which the soil is formed in three-to-four-foot-wide (1.0–1.2 m) beds, which can be of any length or shape. The soil is raised above the surrounding soil (approximately six inches to waist-high), is sometimes enclosed by a frame generally made of wood, rock, or concrete blocks, and may be enriched with compost. The vegetable plants are spaced in geometric patterns, much closer together than in conventional row gardening.
soil content - the soil that is generally used is mostly manure, compost and soil mixtures instead of ground soil; appearance - raised beds generally make very decorative gardens because the gardener enjoys maintaining them.
Lastly, connect your anchors using a heavy-duty string or twine, creating a grid-like pattern of planting squares. You can see an example of the results of this process in my garden bed here: Square Foot Planting Squares.
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.
