This 3×3 Cedar Raised Garden Bed and Greenhouse Cover System brings together two dependable components: a handcrafted Timberlane Gardens cedar bed and a full-size cold frame cover designed to protect plants in unpredictable weather. This combination creates a controlled environment that supports early planting, extends the season, and keeps crops sheltered from frost, wind, and animals.
Each cedar board is hand-cut from Select Cedar and joined with traditional mortise-and-tenon joinery for a stable, tool-free raised bed, with solid oak pegs locking the panels together without metal hardware. We use sustainably sourced Select Cedar from the Pacific Northwest, grown right here in the USA and left completely untreated. Cedar is naturally rot-resistant with no chemical coatings, preservatives, or wood treatments added, and is safe for growing herbs, salad greens, vegetables, and other edible plants. The greenhouse cover adds a clear PVC enclosure supported by a powder-coated steel frame, providing dependable insulation and ventilation when your plants need it most. Both pieces assemble quickly, making this system a practical option for any home garden, patio, or small-space setup.
