Growing Media

Potting Mix vs. Potting Soil

Depending on where you reside, growing media suitable for container gardening may be labeled as Potting Mix or Potting Soil. Use the following guidelines while shopping for growing media you intend to use in your EarthBox® growing system:

  • Growing media should be Sphagnum peat-based (70%-95%) with perlite or vermiculite for aeration and drainage.
    • Coir and Composted Bark Fines/Composted Forest By-products are not the same as Sphagnum peat moss, and should be avoided as the main ingredient when selecting growing media.
  • Growing media should be light and fluffy when dry, and spongy when wet.
  • DO NOT use growing media with these ingredients:
    • Rock, clay, sand, topsoil, compost

You'll need 2.0 cubic feet (60 dry quarts) for each standard-size EarthBox® Original gardening system and EarthBox® Root & Veg™ gardening system; and 1.0 cubic foot for each EarthBox® Junior™ gardening system.

When you first set up your EarthBox® gardening system, we recommend using dolomite to add calcium and magnesium to the growing media to help raise the pH and combat Blossom End Rot (BER).

DO NOT use hydrated lime or pickling lime in place of dolomite.

A note about agricultural lime: Generally, agricultural lime should not be used in the EarthBox® gardening system because it does not contain enough magnesium.

The following brands are suitable for use in the EarthBox® gardening system:

  • EarthBox® All Natural Dolomite
  • Espoma Garden Lime
  • Whitney Farms Dolomite Lime

EarthBox® Original and EarthBox® Root & Veg gardening systems: Use two cups (or 1 lb.) of a dry, granular fertilizer. Use three cups if using organic fertilizer.
