The history of environmentalism in the suburbs Crabgrass Crucible includes this description of how Levittown encouraged good looking lawns:

Abraham Levitt, among others, remained keenly aware of the additional work and expense suburban horticulture demanded, as well as the collective benefits that could follow if all Levittowners took the time and trouble to cooperate. However well-chosen and planted, all their grass, shrubs, and trees would die, and the chickweed prevail, if new owners’ commitments and skills were not also fortified. Through a gardening column in the Levittown newspaper, Abraham opened up a weekly line of communication to bring home to Levittowners how “lawns, like all living things, require care.” He “used to come around in a chauffeur driven car” to check on his homeowners’ floral upkeep. If lawns went unmowed or unweeded, he sent his own landscapers to do the job and followed up with a bill in the mail. Most developers at the lower end, like the Romano brothers, were far less solicitous, especially once their homes had been sold.

As lawn cultivation was taken up by new as well as longtime homeowners, its collective benefits, reinforced by the pressure of neighbors’ peeled eyes, helped make it the most ubiquitous of horticultural practices on Long Island. Whether these residents were white or black, however, their memories downplayed the landscaping contributions of builders and developers. Early Levittowners recalled a “sea of dirt” or mud that surged with rain, an uneven respreading of the topsoil, and scrawny, “inexpensive” shrubbery and trees. Residents later remarked little about any lawn damage from roaming children or dogs, or the neglect of lawn care by a neighbor next door. Instead, whether they were Levittowners or lived in African American Ronek Park, their recollections revolved around a joint if rival pursuit of horticultural handiwork. “Everyone” took up the mowing and watering and often the fertilizing and weed killing. As with Levittowners, Eugene Burnett remember “a kind of competition goin’ with that” that made Ronek Park yards into “some of the most beautiful lawns I’ve ever seen anywhere.” Caught up in the lawn-making enthusiasm, even Robert Murphy tried to plant one outside his Crystal Brook home. Yet for large lot owners, the dynamic was less intensely communal – the Murphy’s lawn was not even visible from the road. For denizens of Old Field, but also for smaller lots of horticultural hobbyists, lawns drew less investment of emotion or energy than other vegetation they cared about. (77)

Three pieces of this stand out to me:

1. The pressure to maintain a nice lawn was present in the early post-war mass suburbs. It may have been present in earlier suburbs but fewer Americans could access those communities.
2. It appears some of this pressure was promulgated by Abraham Levitt, part of the company that founded the community. At the same time, the developers of Ronek Park did less to landscape new homes there and the pressure to have a nice lawn also was present there.
3. There are some hints that social class matters here regarding lawns. Was the lawn an essential part of purchasing a single-family home which offered access to the middle class American Dream? Could a poor lawn reduce or invalidate the success of the new suburban homeowner?

It is hard to imagine images of postwar suburban homes, whether in magazines, film, or television shows, without lush green lawns.
