Soil Calculator

A 4x8 ft raised bed at 12 inches deep needs about 1.2 cubic yards (32 cubic feet) of soil. Use Mel's Mix (1/3 each compost, peat moss, vermiculite) for best results.

Topsoil is natural earth good for filling. Garden soil is topsoil amended with compost and nutrients. For raised beds, use a mix of garden soil and compost for best growing results.
