Build your own raised garden box and join all the gardeners who have discovered how a raised planting area improves drainage and makes it easier to create an ideal soil mixture. Raised boxes are also less demanding physically for people who have trouble bending or kneeling to reach the ground. If you build more than one raised box, leave enough space between them for you to move around and work on each box. Adjust the measurements to create a box that will fit in your garden.
Saw two planks of 6-foot cedar in half to create 4 sections, each 3 feet long. Set aside.
Saw a 4 by 4 stud into four pieces, each 16 inches long.
Stand a 3-foot plank on its narrow edge. Position a 16-inch post upright and so that it overlaps with one end of the 3-foot plank. Work on a flat surface and make the face of the plank that is on the ground flush with the face of the stud that is on the ground. Hammer two galvanized nails through the plank into the stud. Position a second 16-inch stud at the opposite end of the 3-foot plank. Hammer two galvanized nails through the plank into the stud.
Stand a 6-foot plank on its narrow edge. Place the plank on the ground flush with the post and 3-foot plank. Hammer two galvanized nails through the plank into the stud on the side adjacent to the 3-foot plank.
Place the third 16-inch stud at the opposite end of the 6-foot plank. Nail two galvanized nails through the plank into the stud.
Position a 3-foot plank flush with the third stud and adjacent to the 6-foot plank. Nail the plank into place.
Stand the fourth stud at the opposite end of the 3-foot plank. Hammer the stud and plank together. Place a 6-foot plank opposite the other 6-foot plank. Use two galvanized nails on each end to secure the plank to the studs.
Add a second level of planks to the box by standing the planks on their narrow edges and placing them on top of planks of equal length. Secure all planks to the studs with two galvanized nails in each end.
Flip the box over so the side with the studs protruding faces down into the ground. Dig holes to accommodate the studs. Tap down all sides of the box firmly.
Fill the box with the type of garden soil that will support your choice of plants or vegetables. Add seeds or seedlings.
