For a low cedar bed

A four-foot-wide bed needs access from both long sides for easier reaching. Include those paths when choosing the length.

Style: Bed on the ground
Material: Cedar with powder-coated aluminum corners
Warranty: A lifetime guarantee on every purchase, paid as store credit for the purchase price; normal wear and tear is not covered.

Choose the size or layout

Use the widest outside footprint to plan paths. For a soil order, measure between the inside walls after assembly and choose your filled depth; advertised dimensions can be rounded. Rectangular sizes below read length × width × height.

Gardener’s Supply doesn’t publish inside measurements or an outside size for these beds, so the soil figure below is the maker’s own stated capacity. If you’ll fill it less deep, measure between the inside walls once it’s built.

Before and while you build

On a lawn, Gardener’s Supply suggests lifting the sod and loosening the soil 6 inches deep first.
Each board has a smooth side and a rough side: choose which faces out before sliding the boards into the corners.
Seat every board fully, level with the bottom of its corner, then screw through every hole in the corners.

Prepare and assemble this bed

Compare the material, bottom and care choices if you are still deciding between families. Follow the site preparation and liner checklist for the supporting surface.

Choose the exact configuration and lay out its parts. Check the required tools in the selected kit instructions.
Prepare a stable, level position and confirm the outside footprint with working paths.
Check corners, fasteners, protective edging and any layout-specific braces against the kit instructions before adding fill.
Measure the finished inside and outside separately, then update your plan. Preserve the maker’s fill restrictions.

Mark the outside footprint on the ground before assembly, including any legs or protruding corners. Leave a route for carrying bags, reaching the plants and maintaining nearby beds.

This bed stands on the ground; its maker does not say whether it has a bottom, so look at the parts before you fill it. Check the soil and drainage where it will sit before adding fill. Its wall height is not a prescription for how deep the growing mix should be.
