Depending on where you reside in the U.S., growing media that is suitable for container gardening may be called Potting Mix or Potting Soil. To make is easier on our customers, we have provided a list of suitable brands that can be used in the EarthBox. If your local garden center does not carry any of these, we have listed some guidelines, below, to keep in mind while shopping for growing media.

We recommend using 2 cubic feet (60 dry quarts) of a peat-based (70%-80%) growing media that contains perlite or vermiculite. It should be light and fluffy when dry, and spongy when wet. It should NOT contain any rock, clay, or sand. You should also avoid using topsoil or compost.
