Why Do We Need Lawns Again?

A growing number of Americans can look back and remember a yard of green grass as part of their childhood. The patriotic image of a single-family home and a white picket fence would seem momentarily out of place without the mowed lawn, but how often are they actually used? What is the underlying impetus besides their (seemingly) traditional picturesque quality? Given a closer look at what all of real costs of having a lawn actually are, it may be time to question whether or not they’re as vital as American culture would suggest.

The Great American Lawn

Typical American Home

Try Googling “American Home” and see how many images include a lawn. It’s the vast majority.

For something that has grown to be the foreground in the image of the American Dream, lawns are not an American creation. In fact, there was a time not that long ago when expanses of grass were just as rare in the United States as they are in the rest of the world. Short, edged, manicured grass was originally a component of the English garden, prized for its formal plan and meticulous upkeep. Though created to promote the beauty of nature, relatively little was natural about these hyper-constructed landscapes. It was only a matter of time before a growing wealthy class in America imported the idea of expanses of well-trimmed green rolling over their grounds.

Even then, however, American lawns were a luxury reserved for those that could afford to pay others for the high cost of maintenance. Before 1827, livestock was the most economical way of keeping grass short and most people in smaller homes opted for yards of vegetable gardens or gravel. It was the cylinder push mower, invented by an Englishman named Edwin Budding, that eventually opened the realm of feasibility to a wider American audience.

The idea of a thick, green front lawn was not the only thing that was imported from outside of the United States. We actually needed the grass as well. With younger, suburban generations being surrounded by lawns since the beginning, it’s easy to think that we simply culture species that grows naturally in the U.S. As it turns out, grasses native to the great American plains could not be trimmed to the carpet-like fullness of English gardens, but English grasses proved not hardy enough for the seasons in the American climate. Thanks to the stalwart efforts of the U.S. Department of Agriculture and the U.S. Golf Association (not such a surprising alliance) by 1915 we had blends of seeds that could provide stable, beautiful lawns across the country. The post WWII flight into suburbia had acres of possibility waiting, complete with plenty of grass seed to go around.

Finally, every home could have not only the brick chimney and the white picket fence, but a little piece of formal garden all to its own. After all, it only takes 3 billion hours of time and $40 billion a year for America to keep its lawns lush. The numbers may seem big, but they’re not all that surprising when they represent 25 million acres of land (about the size of the State of Virginia) according to author Evan Ratliff in his paper “Turf Wars.”

The Drawbacks of Sprawling Green

One can certainly start with water. The perfectly green lawn requires regular hydration, but how much exactly? The Environmental Protection Agency pegs water usage on the average lawn at around 10,000 gallons a year (a year’s worth of showers). Irrigation remains the largest source of water use in the country. For most Americans, that’s potable water pulled from an aquifer or reservoir.

For Americans, the green lawn brings many fringe benefits such as privacy, an image of wealth and increased curb appeal of the home. Yet despite the decades of engineering that has gone into perfecting the American lawn, it still has an annoying tendency to encourage unwanted side effects: bugs, weeds, moss. For some reason nature has continued to have a stubborn tendency of promoting imperfections in this artificially conjured monoculture.

Fortunately, this is nothing that chemicals can’t fix. Americans spread around 90 million pounds of fertilizer and 78 million pounds of pesticides annually, the bulk of which are petroleum based. While portions of these chemicals may help create the appearance of a healthy lawn (because grass can be healthy even when it is dormant and brown) they do not promote health in much else, including humans. The CDC continues to find residential pesticides in the blood and urine of Americans of all ages.

Eartheasy points out that 30 commonly used lawn pesticides, 19 are linked with cancer, 13 are linked with birth defects, 21 with reproductive effects, 26 with liver or kidney damage, 15 with neurotoxicity, and 11 with disruption of the endocrine (hormonal) system. Of those same pesticides, 17 are detected in groundwater, 23 have the ability to leach into drinking water sources, 24 are toxic to fish and other aquatic organisms vital to our ecosystem, 11 are toxic to bees, and 16 are toxic to birds.

There’s always the cutting. Americans utilize an estimated 38 million lawnmowers in order to keep their grass trim and tidy. Having walked behind a mower a number of times in my youth, I’ll admit there is something cathartic about the steady pacing back and forth with the world drowned out by the hum of a gas powered engine. A suburban zen, if you will. The catch is that lawnmower engines have traditionally been dirty beasts, producing as much pollution in an hour as a car traveling 100 miles. One of the key reasons is the absence of the catalytic converter found in our automobiles–deemed an expensive addition to a piece of lawn equipment by the industry. When all is said and done, lawn care is a prime contributor to smog and low-level ozone, accounting for nearly 5% of air pollution in the warmer months of the year according to the EPA.

Why the Devotion?

A question more consistently asked these days is despite all of the drawbacks, why is the dedication to the American lawn so strong? What drives the carnal passion for stepping out the front door and gazing over the sea of tiny green blades separating a house from the road?

The strongest reason always seems to be the “playscape for children,” but having grown up in numerous suburbs I have to question whether or not this is really used as often as our collective romantic nostalgia lets us believe. Having some elbow room between neighbors seems more likely. Perhaps the image of a carefully maintained lawn rather than natural plantings makes it easier to justify owning larger plots of land? Maybe it is because our culture has made lawn care relatively straightforward where the process of maintaining a landscape of natural species is foreign to most of us?

I would guess that the biggest reason is inertia of a cultural image. We have a tendency to lose sight of the momentum that a status quo has in our society. The residential lawn probably means the same thing to Americans that it meant to wealthy English landowners back in the 17th century: a symbol of opulence and sophistication. But just like the expectation of having a formal living and dining room, the fixture of the American lawn is ripe for reassessment. Newer planning models are already putting the necessity of the lawn into question. Dwell Development’s “microcommunity” model gives a new face to the idea of suburban planning, giving their homes almost no yards and placed closer together in order to promote a stronger neighborhood and transit-oriented development.

There are many beautiful landscapes that can be made from local, native plants requiring a fraction of the care and water and chemicals that we sprinkle over grass. Vegetable gardens are also a prime candidate for yard space, giving our green thumb a chance to reach into the dirt while literally giving back some fruits of the labor.
