A raised-bed garden offers the benefit of a contained garden bed that is often simpler to tend to when compared to traditional beds. You have complete control over the quality of the soil in the raised bed, which is especially important if your area has poor soil. Weeds may pose less of a problem in a raised bed, and the small size makes it easier to reach the plants in the center of the bed. Construct a garden box, or raised bed frame, and set it in a sunny area. Once it's filled with soil, you are ready to begin raised-bed gardening.
Lay a 12-inch long, 4-by-4-inch block of wood on the ground. Set one end of an 8-foot-long, 2-by-6-inch board on top the block. Line up the end of the 2-by-6 so it is flush with the bottom and side edge of the 4-by-4.
Screw the 2-by-6 to the 4-by-4 using two screws that are evenly spaced and a power screwdriver. Set a second 8-foot long 2-by-6 next to the first one and line its edges up with the top and side edge of the 4-by-4 and screw it into place with two screws.
Set the second 4-by-4-inch block under the other ends of the two 2-by-6-inch boards, lining up the edges. Screw the 2-by-6-inch boards to the block, using two screws per board.
Attach the final two 4-by-4-inch blocks to the final two 8-foot-long 2-by-6-inch boards in the same way you made the first set. These are the two long sides of the garden box.
Stand the long sides up on their sides. Set one of the 4-foot-long, 2-by-6-inch boards at one end, lining its edges up with the ends of each side to create a three-sided box. Screw the 2-by-6 to the blocks, using two screws per end.
Place a second 4-foot-long 2-by-6 at the other end of the side boards, lining it up with the edges of the sides to form a complete box. Screw the 2-by-6 to the blocks.
Stack the third 2-by-6 on top on of the end pieces and screw it to the blocks, completing the end of the box. Place the fourth 2-by-6 on top the other end and screw it into place. The box now consists of four sides that are each two boards high, with the boards attached to the blocks.
Set the garden box in a full sun area of the garden. Fill it with soil and plant the garden in the raised bed.
