To build a raised garden bed, choose the location, map out the garden, tend the soil, make the beds and fill the beds with soil. You need a level, compost, manure, newspaper, topsoil, 2-by-6 wood, a shovel and galvanized screws to complete this project.
- Select the location
Choose a spot that gets a minimum of eight hours of sunlight each day, has access to water and has a flat surface.
- Outline the size and shape of the garden
Make sure the garden bed is 4 feet wide to make it accessible on both sides.
- Construct the garden site
Use a shovel to loosen the soil to a depth of 8 to 12 inches to make room for the roots. Use landscape fabric, cardboard or newspaper as a first layer, and place soil and other additives on top.
- Make the bed
Use 2-by-6 cedar or rot-resistant lumber to construct a bed with a depth of 6 inches. Cut the wood in pieces, and fit them together using butt joints and galvanized screws.
- Balance the frames
Use a level to ensure that the frames are level on each side. Remove enough soil beneath the bed until the frame is balanced.
- Fill the bed
Place compost, manure and topsoil in the beds. Rake the soil until it is even.
