Framed or mounded, raised beds give plant roots the space they need
Gardening in raised beds has been a common practice for centuries. "Raised" means the soil level in the bed is higher than its surrounding, and "bed" implies it is small enough to work from the walkways.
Water-wise gardening conserves water and helps protect the environment. A xeriscape is a “dry scene” that uses very little water, but a water-wise garden includes any style that is designed to conserve water.
