For a mid-height cedar bed in the size your space takes

Gardenary states no soil capacity, but whether its sizes are inside or outside, a bed holds no more than its size times its height. Filled to the brim, the 4 × 8 ft bed takes at most 48 cubic feet (32 bags of 1.5 ft³) and the 3 × 6 ft bed 27 (18 bags). If those are outside sizes, the 1-inch boards leave about 46 × 94 in inside a 4 × 8: 45 cubic feet, or 30 bags. Measure between the walls once it’s built.

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.

Gardenary doesn’t publish inside measurements, an outside size or a soil capacity for these beds. Measure between the inside walls once it’s built before you order soil.

What to plant in it

Four planting plans drawn to scale for each size, from a salad bed to roots and onions, with every plant counted: 2 × 6 ft bed · 2 × 8 ft bed · 3 × 3 ft bed · 3 × 6 ft bed · 3 × 8 ft bed · 4 × 4 ft bed · 4 × 6 ft bed · 4 × 8 ft bed.

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.

  1. Choose the exact configuration and lay out its parts. The body slides together without tools; the top trim needs a hand drill and the screws in the box.
  2. Prepare a stable, level position and confirm the outside footprint with working paths.
  3. Check corners, fasteners, protective edging and any layout-specific braces against the kit instructions before adding fill.
  4. 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.

The cedar arrives untreated. Before you fill it, Gardenary recommends staining the inside with its Eco Restore Wood Treatment so the wood lasts longer.
