Organic gardening is growing and marketing health foods that have not been treated with commercial chemicals. Only natural fertilizers and pest repellents are used to qualify for the higher, health food prices.
The primary equipment for health food growing is to not use the chemical fertilizers or toxic pesticides.
Natural and organically grown foods command higher prices because they cannot easily be mass-produced and generally require more TLC.
Not only are natural foods more expensive, they are mandatory for people who cannot tolerate many of the chemicals commonly used by the majority of growers today. There are also many people today who feel very strongly about chemicals and are willing to pay extra for all natural products.
