Raised beds offer a guaranteed quick fix for those with inadequate garden soil. Construct a frame, add quality soil, and the issue is resolved.
Like is the case with all quick fixes, though, the devil is in the details.
The frame, which is usually built out of wood, rots or otherwise degrades because of the high water content in the soil and getting baked in the sun all summer, leading to soil runoff. The soil compacts as time goes on and requires topping up.
Speaking of water, most raised beds can benefit from an automatic watering system because, like all containers, they dry up quickly.
Depending on the terrain they are on, which is usually unsuitable for gardening, and the very reason they were built in the first place, the water may settle to the bottom and lead to root rot. This brings us to the need to incorporate a drainage system.
That said, here are the advantages.
The soil quality can be perfectly controlled, and raising the borders makes gardening easier for people with back problems.
The frame can be moved as the landscape changes in time, turning a former sunny spot into a full shaded one.
It's easier to adjust the growing medium over time compared to the garden, where soil stratification always returns it to its initial condition.
You can have any soil you want in a raised border: loose and sandy for carrots or rich and heavy for eggplants.

Deep planting borders have been created to maximize the yield of even the smallest vegetable garden.
The technique involves digging much deeper than a shovel's depth, which is usually a foot.
The three-foot-deep ditches are filled in layers with garden soil, straw, aged manure, and compost, mounded slightly above the edge.
Borders need to be a maximum of three feet wide for single-sided access, and five feet wide for dual-sided access. To ensure the soil remains loose and airy, they must not be stepped upon.
Deep planting borders provide several advantages.
Decomposing organic material generates heat, which permits the early cultivation of vegetables sensitive to cold.
Abundant crop food is supplied by this rich organic content, and the soil's loose structure allows for deeper roots, thereby enhancing drought resistance.
With a deep planting border, you can achieve two or three times the yield compared to a regular plot of the same area.
