Is vermiculite bad if eaten by infants?
Potting soil typically has more nutrients and is mixed with peat in it for the roots to grow deep and strong in. It s thicker and helps retain moisture in a hanging pot for example. It also costs more. Top soil is obviously used to fertilize either a planter bed or lawn to give the plants/lawn roots food/nutrients to grow and prosper.
Potting soil has been sterilized. Those with vermiculite added will retain moisture and not compact.
