So, What is a Raised-Bed and why should you use one?
A Raised-Bed is as simple as it sounds. The garden bed, comprised of soil and finished compost, is raised above the level of the surrounding ground. This can be achieved by containing the Raised-Bed with some type of bordering material; Rock, Stone, Cinder-Block, or more commonly Wood. Raised-Beds can also be border-less, the bed is simply piled up and planted into.
As for why you should use one, It’s simply a shortcut to well prepared, fertile, and friable soil. It’s much easier to dump compost and topsoil inside a wooden frame on the ground than it is to dig up the same area and amend the existing soil.
