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 is open to the ground. 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.
