Building a Cedar Raised Garden Bed

Gardens thrive when you control the foundation. By building a raised bed, you bypass poor soil conditions, improve drainage, and create a manageable workspace that saves your back during planting season. A well-built bed stays square for years, holds its shape against the weight of heavy, wet soil, and provides a clean aesthetic that separates your vegetables from the wilder parts of the yard. Success here comes down to lumber choice and level ground. We use untreated cedar or redwood because they resist rot naturally without leaching chemicals into your crops. Take your time clearing the sod before you start; if the base isn't level, the water will pool in one corner and cause uneven growth. Get the structure right today, and you will be harvesting from it for seasons to come.

1. Start with level ground. Measure your footprint and remove all grass and debris from the area. Use a long board and a level to ensure the ground is perfectly flat, shaving down high spots as you go.
2. Measure and cut boards. Cut your cedar boards to your desired lengths. Use 4x4 posts as corner braces, cutting them to the exact height of your side walls to ensure structural stability.
3. Screw walls to posts. Position your side boards against the corner posts. Drive exterior-grade deck screws through the boards and into the posts, keeping the edges flush.
4. Dial in perfect corners. Measure diagonally from corner to corner. If the measurements match, the frame is square; adjust slightly until they align perfectly.
5. Anchor the frame down. Place the frame in its final position. Sink your corner posts slightly into the ground if you need extra stability, or stake the inner corners with rebar.
6. Fill and settle soil. Line the bottom with landscaping fabric if you want to suppress weeds. Fill the bed with a mix of high-quality compost, peat moss, and topsoil.
