Raised bed vegetable gardens are elevated so that they are higher than the surrounding soil. Gardeners choose raised vegetable beds so they can put in nutrient-rich soil, rather than trying to supplement the existing ground soil. Raised bed vegetable planters are an attractive landscape feature, which compliment the home and outdoor areas. Raised bed gardens are effective for flowers as well as vegetables.
Choose a location for the planter. The ideal location will get direct sunlight for the majority of the day and have an even ground surface.
Place a garden hose along the ground to define the edges of planter. The planter can be any shape desired, including circular, square, rectangular or any other desired design.
Place a single line of retention wall stones along the line of the garden hose. Lay each stone flat, and place them end to end along the entire length of the garden hose.
Cut a retention stone in half using a masonry saw, and place the half piece at the farthest left side of the wall, on top of the existing stones. Lay additional full-size stones on top of the first layer until you reach the end of the first row of stones. When positioned properly, the centre of each second layer stone will overlap two stones underneath it.
Continue adding layers of retaining wall stones until the planter bed is 12 to 18 inches high.
Fill the interior of the stone planter with topsoil that is well draining. Unless you have large amounts of soil available, you will need to purchase topsoil from a garden centre. Fill the raised planter with soil until it is within 4 to 5 inches of the top. This space allows you to place mulch on top of the soil after planting.
