Break ground in a sunny spot with good drainage to establish your backyard vegetable garden. Till compost into the soil to add nutrients. If your soil is poor quality, build raised beds no wider than 4 feet using wood or concrete blocks.
A backyard garden needs a minimum of six hours of sunlight daily to support vegetable growth. Avoid a location near a tree or other large plants that will compete for nutrients. Locate the garden close to the house to discourage wild animal pests if possible.
If you want to plant directly in the ground, mark the area with stakes and string. The size depends on how much you plan to plant. A smaller plot is easier to manage, especially for beginning gardeners. Dig the grass out of the marked area. Till the plot to loosen the soil and prepare it for planting.
For raised vegetable garden beds, choose an area that allows enough space for the bed plus space to walk around the box. A maximum width of 4 feet allows you to reach to the middle so you can tend the garden. Wood is common for raised beds, but it can rot. Concrete blocks prevent rotting. The bed should be at least 6 to 12 inches deep.
