In order to get and maintain organic certification, an organic farmer must adhere to a strict set of guidelines, which include a prohibition of synthetic chemical fertilizers and pesticides. Growing healthy plants organically requires building fertile soil through careful management – encouraging a healthy ecosystem of molds, fungus, bacteria, and insects that do the work of converting their surroundings into plant food. The best way to do this is to add natural (organic) material that breaks down into usable nutrients as it decomposes.
As a self-anointed organic home gardener, I have only myself to answer to – no one is testing my soil for chemical residue, no one would know if I were dosing my plants with Miracle-Gro (or spraying poison on the circus sideshow of bugs). I adhere to organic methodology as a matter of sustainability and self-sufficiency, and out of concern for my local environment and my own, and my loved ones', health.
