Place one of the corner supports in the angle between the boards and attach it to the side board with three screws. Repeat for the remaining three corners.
Attach the center brace to join the two sides at their midpoints. Use a square to position the brace at a right angle to the sides (5). The brace prevents the sides from bowing outward when the bed is filled with soil.
The finished bed measures 4 feet by 8 feet—a size that makes seed sowing, weeding, and harvesting easy—and raises the planting level by almost a foot. The wood can be stained, if desired. We liked Coach’s raised beds so much, we built 10 of them for the garden. —Doug Hall
