The dark side of domestic life is suppressed to provide a comfortable image. The lawn is equated with domestic harmony. Indeed, the domestication of grass is the privileged representation of domesticity itself. An endless array of aggressively happy families poses on perfect grass eating, drinking, cooking, sleeping, and playing. Clothes change but the lawn remains the same.
Healthy families have healthy lawns.
To feed your lawn is to feed your family. In fact, activity in the American suburbs was usually restricted to the concealed backyard. The lawn is first and foremost an image, something to be seen rather than used. Enormous effort is spent on constructing the right visual effect. The whole point of lawn care is that you do not have to display the family.
