Is potting soil sterile or devoid of bugs, eggs, etc?
I'd like to use something besides seed starting mix for some potted herbs at the office.
I brought a plant in the office that had been in the ground and within weeks the smallish insects became a problem.
I think a typical potting soil has been cooked or something to eliminate these little bugs, hasn't it? What do you guys use for an indoor plant that won't introduce bugs?
