Raised-bed gardening is a form of gardening in which the soil is raised above ground level and usually enclosed in some way. Raised bed structures can be made of wood, rock, concrete or other materials, and can be of any size or shape.[1] The soil is usually enriched with compost.[2]
Vegetables are grown in geometric patterns, much closer together than in conventional row gardening.[2] The spacing is such that when the vegetables are fully grown, their leaves just barely touch each other, creating a microclimate in which weed growth is suppressed and moisture is conserved.[2]
