3 sizes and layouts

Listed capacity: 6.7 ft³
Soil to fill it: 5 bags of 1.5 ft³
Planting depth: 10 in

Drawn from the maker’s published figures: the footprint from above on the left, the height on the right, in inches. Every bed on this site uses the same two scales.

For an elevated wooden planter

Use potting mix. This planter excludes ordinary garden soil, topsoil, sand, clay and rocks, so those are not substitutes for the fill.

Style: Elevated planter
Material: Cedar sides 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.
Bottom: Contained planter

Planting from a wheelchair, or looking for a bed you don’t have to kneel at? Accessible raised beds gives the heights, widths and knee room that work.

Planning a balcony, deck or roof garden? Have the surface assessed for the filled weight before buying the planter. Its own load rating does not establish what the surface can carry. Work out the filled weight for whoever checks it.

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.

What to plant in it

A planter on legs suits the crops whose main roots stay in the top 6 to 12 inches: what to plant in a raised bed with legs.

Before and while you build

Gardener’s Supply says it is easiest with two people.
Set the vents with their louvers slanting down, so they shed water.
Leave small gaps between the floor planks for drainage, then lay the liner over them.
It holds about 7 cubic feet of potting mix. Gardener’s Supply advises against heavy potting soil, and against rocks or broken pottery in the bottom.
The 4 × 4 and 4 × 8 ft sizes have their own instructions.

Covers that fit

Gardener’s Supply protection frame and covers, 2 × 4 ft: a powder-coated steel frame, 47 × 21 inches, with a greenhouse cover and an insect-mesh cover, about 32 inches high at the back and 24 at the front. Gardener’s Supply names the 2 × 4 ft size of this bed among the beds it fits, not the 4 × 4 or 4 × 8 ft.

Sold separately; each fit is as Gardener’s Supply states it on the product’s own page. Every cover, trellis and fence we list.

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 floor supports, drains, supplied liner and the chosen leg or caster hardware before filling. Confirm the support beneath the planter for the filled load.
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 planter has a floor. Use the intended planting depth, not the height of its legs, to estimate fill. Account for drainage and the filled weight when choosing a level location.

Gardener’s Supply specifies potting mix for this planter and excludes ordinary garden soil, topsoil, sand, clay and rocks.
