‘Organic’ when it comes to plants refers to how it was grown. It can only use naturally occurring fertilizers, pesticides and growing practices. That includes the substance in which they grow, and for most of the world that’s soil. In fact, many organic growers consider the overall health of the soil to be the foundation for their practice. In the US, the United States Department of Agriculture sets the standard for what producers need to do in order to be able to call their crops organic. There’s many different standards around the world, but all share a common understanding around sustainability and the importance of soil.
