Potting Soil vs. Potting Mix: What’s the Difference?

You’re confused about the difference between potting soil and potting mix.

Definitions

Potting soil contains actual decomposed organic matter (soil). Could be decomposed bark, peat, leaf mold, etc. Heavier, retains moisture longer, smaller particles. Better for tall woody plants that need weight to stay upright.
Potting mix is a blend of ingredients for growing plants—typically peat moss, perlite/vermiculite, possibly bark, but no decomposed matter. Lightweight, ideal for hanging baskets, window planters, containers. Great for annuals and seasonal color.

Base choice on plant needs: weight and moisture retention (soil) vs. lightness and drainage (mix).
