A round bed 24 in across and 11.5 in deep, which gives a spacious planting area in a shape that behaves differently from a rectangle. Every point on the rim sits the same distance from the center, so reaching the middle to plant or pick never means leaning across a long side, and arranging a mixed planting becomes a matter of working outward in rings rather than squaring off rows. The circle also reads as a deliberate feature in a space instead of a utility box, giving an organized garden look wherever it is placed. Underneath, the base is left open. Water drains directly into the ground rather than standing in the bottom of the bed, and air circulates up through the soil column from below, which keeps the root zone from turning stagnant in the way a sealed container will. Roots are free to travel down past the wall into native soil. The walls are galvanized steel, corrugated rather than smooth: the ridges reinforce a thin sheet against the constant outward pressure of wet soil, so the ring holds its circle instead of deforming into an oval over a season, and the zinc coating keeps rust off through repeated soakings. Tightly fastened screws hold the panel joints steady in daily use. At 5 lbs the bed is light to carry into position, assembles from the box, and suits patios, lawns, gardens and balconies.
