How to Build a Wood Raised Garden Bed

Are you interested in starting a garden but don’t have the space or suitable soil? Building a wood raised garden bed is a great solution. Raised garden beds offer numerous benefits, including improved soil drainage, easy maintenance, and extended growing seasons. In this article, we will guide you through the step-by-step process of building a wood raised garden bed.

Step 1: Determine the Location

The first step in building a wood raised garden bed is to determine its location. Consider factors such as sunlight, wind exposure, and access to water. Ideally, the garden bed should receive at least 6 hours of sunlight per day. Additionally, it should be easily accessible for watering and maintenance.

Step 2: Decide on the Size

The next step is to decide on the size of your raised garden bed. It should be at least 6 inches deep, but if you are building it over concrete or stone, a depth of 10 to 12 inches is recommended. The width should allow you to reach the middle without stepping on the soil, typically around 4 feet.

Step 3: Choose the Right Wood

Choosing the right wood is crucial for the longevity of your raised garden bed. Untreated wood is recommended, as it avoids potential chemical contamination of the soil. Cedar is a popular choice due to its natural rot-resistance. Other suitable options include redwood, juniper, douglas fir, cypress, black locust, and pine.

Step 4: Design Your Garden Bed

Once you have chosen the wood, it’s time to design your raised garden bed. Consider whether you want to stake it in the ground for added stability and durability. You may also want to add a rim around the top for both style and convenience.

Step 5: Start Building

Now it’s time to start building your raised garden bed. Begin by cutting the wood boards to the right size. You can use a saw or have them cut at a hardware store. Make sure to measure carefully to ensure a precise fit.

Step 6: Assemble the Bed

Next, drill pilot holes into the boards to prevent splitting, then screw them together to form a box shape. Use a level to ensure that all angles are square. You can do this by measuring the dimensions diagonally from one corner to another.

Step 7: Level the Bed

It’s important to make sure that the bed is level before proceeding. Adjust the boards or dig into the ground if necessary to achieve a level surface.

Step 8: Add Soil

Now it’s time to add soil to your raised garden bed. Use a mixture of compost and nutrient-rich soil for optimal plant growth. If you are building the bed over grass, consider layering a compostable material like cardboard or wet newspaper to suppress grass growth.

Step 9: Calculate the Amount of Soil

Before adding soil, it’s important to calculate the amount you will need. Multiply the length, width, and depth of the bed to determine the total volume. This will help you ensure you have enough soil to fill the bed adequately.

Step 10: Start Planting

Now that your raised garden bed is complete, it’s time to start planting. Choose the plants that are suitable for your region and gardening goals. Consider factors such as sunlight requirements, water needs, and plant spacing.


Building a wood raised garden bed is a rewarding and practical project for any gardener. It provides a controlled environment for plants to thrive and offers numerous benefits such as improved soil drainage, easy maintenance, and extended growing seasons. By following the step-by-step guide outlined in this article, you will be able to create your own flourishing garden bed.
