At about 1.7 and 2.5 cubic yards full, a delivered load is worth a quote. Every part of the E is 2 ft wide, so you reach across it from one side, and cross boards divide it into boxes, 8 in the smaller bed and 11 in the larger: a box for each crop.

The floor sits about 1 inch above the ground, Gardenary says, so the soil can be a little shallower than the height: measure inside once it’s built. While the steel weathers it can stain light or porous surfaces, so Gardenary says to stand the planter on grass until then; it suggests a vinegar and salt spray to speed the weathering.
