Potting soil – as opposed to native soil, loam, dirt or landscaper’s soil – is what should be used in pots no matter what the crop. It should be light, loose and well aerated, fertile and full of biological activity.
I do not recommend peat moss-based potting soils. Why? Peat moss is anti-microbial. Microbes don’t grow well in it. That’s just the opposite of what we want. Peat moss is good for storing bulbs or shipping food or other live material. Potting soil should not sterile as some recommend, but alive and dynamic. It should be light, well aerated, full of microorganisms and have the ability to stimulate quick and sustained growth.
Interior plants and outdoor potted plants should be planted in a well-drained, organic potting soil like I recommend. My favorite basic ingredients are compost, coconut fiber, and expanded shale. My latest recommended formula is as follows:
40% compost
40% coconut fiber
10% expanded shale
10% mix of lava sand, greensand, and alfalfa meal
