What "raised garden bed" means in gardening

A raised garden bed is a type of garden that is built above ground level, typically using wood, bricks, or other materials to create a raised platform. This allows for better drainage and easier access for planting, weeding, and harvesting. Raised garden beds are often used in urban or suburban environments where the soil quality is poor, or where space is limited. They can also be used to create a more decorative or ornamental garden, as the raised design allows for more creative landscaping options.
