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.
Epic Gardening 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.

Where the maker’s figures disagree
- The pages call the steel aluzinc (aluminum-zinc coated) and, in one line, galvanized; they give two different figures for how much longer it lasts than galvanized steel.
Measure the inside of the assembled bed before ordering soil.
What to plant in it
Four planting plans drawn to scale, a salad bed, a kitchen bed with herbs, tomatoes and peppers, and roots and onions, with every plant counted: 2 × 6 ft bed · 3 × 6 ft bed · 4 × 4 ft bed.
Questions about this bed
Can it stand on concrete or a patio?
Yes, with a liner: on pavers, concrete, tiles or a porch, Epic Gardening says to lay a bed liner or geotextile fabric inside the bed and up its sides, which lets water drain but keeps the soil off the floor. To protect the surface more, it suggests thick builder’s plastic under the bed. Before you fill it on a patio or deck.
Can two beds be joined?
Yes, Epic Gardening says, and it always recommends bracing bars when you combine two, to keep the sides from bowing under the soil’s pressure.
Bags, or a bulk delivery?
For its 15-inch beds, Epic Gardening recommends a raised-bed mix from a local landscape or bulk-soil supplier, which can cost less than bags. It also suggests filling the bottom partly with small branches, wood chips or compost, or larger logs in its taller beds, and keeping the best mix for the top, where most vegetable roots grow. Filling a deep bed for less.

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.
