Which gardening technique involves planting in raised beds?

Raised bed gardening is a technique that specifically involves the creation of raised planting areas, which are usually constructed from wood, stone, or other materials to create a defined space above the ground level. This method allows for better soil drainage, improves soil quality, and can enhance plant growth by providing a warmer environment in cooler seasons. Raised bed gardening also reduces soil compaction and makes it easier to manage weeds and pests due to the distinct boundaries.

In contrast, container gardening refers to planting in movable containers, which can vary in size and type but do not involve constructing a bed. Square foot gardening is a specific method of planting intensively in a small area, typically using a grid system but may not necessarily involve raised beds. Hanging gardens, while an interesting method for growing plants upwards and saving space, do not involve traditional soil-based planting in raised formations. Therefore, raised bed gardening is the most appropriate choice for the practice of planting in raised beds.
