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 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.
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 × 4 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.
- 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.
