Rip all of it out, she stated. Each blade of grass, frontyard and again. As quickly as my spouse heard the town was providing a rebate, she wished to interchange our lawns with bark mulch and bunchgrass.
“We’ll save on the water invoice,” she stated. “And we’ll assist the surroundings.”
I had my doubts. What would neighbors suppose about disrupting the procession of tidy, inexperienced rectangles that outlined our block? What about resale worth? Would our canine miss her previous yard?
My spouse frowned.
The following debate lasted for weeks, a back-and-forth revived by every new report of drought and water restrictions. It has left me with a necessary query: Is there any such factor as a guilt-free garden in L.A.?
The Los Angeles Division of Water and Energy supplies about 91 billion gallons of water to residential prospects annually. Whereas a lot of that’s used for ingesting, cooking and washing, as a lot as half goes to grass, vegetation and bushes, in accordance with estimates. That’s 45 billion gallons.
Even with final winter’s rains and Southern Californians reducing again throughout the drought, the specter of future dry spells and a dwindling Colorado River have bolstered the case for altering the best way we panorama in a Mediterranean local weather.
Grass — or turf — just isn’t solely thirsty, it forces out native vegetation and calls for chemical remedies that leak into the sewer system. Was there anybody on the market who would possibly make a case for staying inexperienced?
Don Hodel, an environmental horticulturist and emeritus advisor for the College of California, started his response to that query with a disclaimer: “I do know it’s not fashionable to say you desire a garden anymore.”
However Hodel proceeded to counsel we predict twice earlier than making any large adjustments. Turf has distinctive advantages, he stated. It lures us open air, encourages us to recreate and measurably cools the air on scorching summer season afternoons.
Hodel additionally has a barely totally different view of the maths. Of the water designated for home and enterprise use in California, an estimated 80% goes to agriculture as in comparison with about 20% for city makes use of.
“I’m not in opposition to water conservation,” he stated. “It’s simply that lawns are practical in lots of respects and I don’t suppose we save that a lot, total, by eliminating them.”
As an environmental historian, Ted Steinberg takes the lengthy view of residential lawns. He begins by describing his personal yard.
“From throughout the road, it seems comparatively much like the peerlessly inexperienced lawns of my neighbors,” stated the creator of “American Inexperienced: The Obsessive Quest for the Good Garden.” “However if you get nearer, you discover lots of totally different species of grasses … what some individuals name weeds.”
Therein lies a compromise. Steinberg has borrowed from early American historical past, when lawns had been haphazard at greatest, usually mixing grass, clover and weeds. We’re speaking a few time earlier than sprinkler methods, energy mowers and weed whackers. Householders swung an occasional scythe.
It took one thing drastic to raise our landscaping tastes. It took World Struggle II.
The herbicide 2,4-D was developed as a biochemical weapon that will later be utilized in Agent Orange. Its effectiveness at killing weeds quickly led to an array of garden merchandise marketed to suburbanites in tract properties with sliding-glass doorways that blurred the excellence between inside and outside. Madison Avenue spent “gazillions of {dollars} making an attempt to persuade individuals of the necessity for luscious, inexperienced expanses.” Steinberg stated.

A cultural norm took root, owners feeling duty-bound to douse their yards with chemical substances, fertilizers and water. In my case, that meant frequent visits to Residence Depot to refill for the battle in opposition to cussed patches the place grass wouldn’t develop. Steinberg suggests I used to be offered a invoice of products.
“I’m not anti-lawns,” he stated. “My schtick is anti-perfect lawns.”
If my argument in favor of turf was gaining momentum, it hit a roadblock within the type of Alessandro Ossola. The assistant professor of plant sciences at UC Davis delivered this straightforward, simple, ecophysiological truth.
California has hundreds upon hundreds of species, subspecies and kinds of native vegetation, he informed me. Grasses — not less than the sort we are inclined to seed, water and mow in our yards — usually are not amongst them.
“They’re utterly outdoors the local weather area of interest,” Ossola stated. “The surroundings is simply too scorching and dry.”
Native yards remove the necessity for weed killers and different chemical substances that spill into gutters, winding up within the ocean. They supply a friendlier habitat for bees. Water financial savings could be substantial.
In Los Angeles, the rebate my spouse heard about — it pays residents $5 per sq. foot to a most of $25,000 — has resulted in 53.4 million sq. toes of turf changed since 2009. The LADWP estimates a financial savings of about 2.3 billion gallons a 12 months, or sufficient to supply ingesting water for 28,800 properties.
“We all know the recipe,” Ossola stated when speaking about drought. “If we don’t change our conduct, we’re not going to win this struggle.”
So what occurred at my home?
We tore up the frontyard, changing it with quite a lot of tall grasses and low, flowering shrubs that might be sparingly nourished by a drip system. Simply as my spouse predicted, eliminating that 802 sq. toes of turf diminished our total water utilization by 10% in a single day.
Not solely was the brand new yard environmentally accountable, it truly regarded good and bought compliments from the neighbors.
“Our water challenges are so important and the alternatives are so nice,” stated Heather Cooley, director of analysis on the Pacific Institute. “I’d argue that all of us must do our half.”
There was, nonetheless, a catch.
We stored the garden in again. Like Steinberg, we in the reduction of on watering and stopped fertilizing. Clover, weeds and brown spots quickly appeared.
I used to be superb with that. So was the canine.
