Douglas Kent started gardening as a youngster. At first, it was solely a pastime, however after experiencing California’s 1986-1992 drought firsthand, he started rethinking his interactions with the surroundings and dedicated himself to inexperienced landscaping, gardening, and activism.
“Gardeners are a big-hearted bunch,” Kent, who’s now a panorama contractor and lecturer at Cal Poly Pomona, advised The Each day Beast. “So many individuals pour their hearts into their gardens, considering that it’s really actually good for the surroundings, and in lots of instances, it isn’t.”
He places it one other manner, “Generally, not the whole lot inexperienced is nice.”
Kent’s not alone in sounding the alarm on America’s yards and gardens. Division of Transportation statistics present that American lawn-care tools consumes slightly below 3 billion gallons of fuel per yr, and far of that’s pure waste. In actual fact, the Environmental Safety Company estimates that owners spill about 17 million gallons of fuel per yr simply refueling their garden mowers.

Based on Kent’s analysis, these statistics simply scratch the floor of a far better subject. He calculates that one acre of turf garden contributes 3,112 kilos of carbon emissions annually. That carbon value is equal to chopping down and decomposing a 40-year-old oak tree, Kent stated. Multiply these emissions by the greater than 40 million acres of garden within the continental United States, and you’ve got greater than 124 billion kilos of carbon emissions yearly.
Nonetheless, Kent acknowledges the utility of turf lawns in offering a prepared, “tough and tumble” floor for play and leisure. “[Turf is] one of the best floor to get soiled on and keep clear,” Kent stated.
Relatively than get rid of turf lawns, Kent and like-minded activists suggest easy options to attenuate their environmental prices, and maximize their advantages.

Get Your Fingers Soiled
First, Kent encourages folks to do their garden and garden work themselves. This protects fuel expended by contractors transporting heavy lawn-care tools. Subsequent, Kent strongly advises folks to attempt to use guide machines.
Whereas lawn-care tools like mowers and leaf blowers are far smaller than vehicles, they lack parts controlling their emissions. Working a two-stroke garden mower for one hour can generate as many risky natural compounds—dangerous airborne pollution that may worsen human respiratory and cardiovascular circumstances—as driving a automobile for 350 miles.
Stats equivalent to these prompted California to enact a ban on the sale of gas-powered garden mowers, efficient in 2024. The ban must be a boon for electrical garden care tools. If equipped with renewable vitality, electrical lawn-care tools can do the identical work as their gas-powered rivals, with none carbon emissions, noxious fumes, or dangerous particulates. In addition they create far much less noise air pollution.

Even in California, although, solely 33 % of electrical energy is generated by renewable sources. Till America’s electrical grid goes solely carbon impartial, electrical garden care tools received’t be fully inexperienced. Nonetheless, activists like Kent have environmental considerations associated to cobalt, lithium, and nickel of their batteries—minerals that each one must be mined in environmentally dangerous methods. Nonetheless, people don’t have to fret about any of that with most guide machines.
“You’ve acquired 3.5 million years of know-how in your physique,” Kent stated with fun. “Break it out. Use it. Get soiled!”
Rethink Your Fertilizers
Kent additionally encourages folks to rethink how they fertilize their lawns. Grass cells require nitrogen to supply the proteins they should develop. Artificial fertilizers get their nitrogen from ammonia, which is usually produced by combining nitrogen from the air, and hydrogen from pure fuel underneath excessive pressures and average temperatures.
The method received its inventor, Fritz Haber, the 1918 Nobel Prize for Chemistry, and has been credited with growing international meals manufacturing and lowering world starvation. Nonetheless, it’s additionally a significant contributor to international local weather and environmental change. A century after its invention, the Haber Course of is now answerable for 1-2 % of world vitality consumption and 1.44 % of carbon emissions.
To chop down on vitality prices related to ammonia manufacturing, Kent advocates using pure fertilizers equivalent to blood meal and bone meal. Based on Dr. Bridget Ruemmele, a professor on the College of Rhode Island’s Faculty of the Atmosphere and Life Sciences, a little bit of analysis can drastically cut back the necessity to fertilize altogether.
“All of our grasses [in the United States], except a couple of species, are literally launched to our nation,” Ruemmele advised The Each day Beast. She added that the native grass species which can be current in the USA are usually suited to simply some components of the nation, not all of them.
Ruemmele stated that planting a local grass species, appropriate to the regional local weather, can cut back the quantities of fertilizer and water a garden requires. People who find themselves uncertain about which species grows greatest of their space can contact considered one of their state’s land-grant faculties or universities and an skilled, like Ruemmele, ought to be capable to inform them. These consultants can even inform residents of greatest upkeep practices for his or her particular species of grass, equivalent to really useful mowing top.
Curb Your Turf
Maybe the best technique of lowering sources expended on garden care is to restrict turf to the place it’s really wanted. Kent argues that turf is pointless in highway medians and workplace parks. Even in yards, he says turf must be restricted to the place folks and pets play and relaxation.
“You don’t must go loopy in your complete again 40,” stated Kent. He asserts that limiting turf and growing a yard’s biodiversity present large advantages. Trees can present yards with much-needed shade, lowering water consumption, and weeds can enhance soil high quality.
Nonetheless, that doesn’t imply yards ought to develop untamed and unchecked.

Strike a Lovely Steadiness
David Mizejeski is a naturalist and spokesperson for the Nationwide Wildlife Federation (NWF), and the previous host of Animal Planet’s Yard Habitat. All through his profession, Mizejewski has labored to assist others perceive how their yards and gardens influence the pure world. Like Kent, Mizejewski recommends that owners permit a variety of plant species to flourish of their yards—however they must be cautious.
“One of many misperceptions if you say ‘create a pure garden’ or a ‘wildlife habitat garden’… lots of people instantly assume that what you imply is let your garden simply go wild, and let it develop like loopy,” Mizejewski advised The Each day Beast.
As a substitute, Mizejewski argues that folks can nonetheless domesticate aesthetically pleasing yards and gardens that strike a stability between a well-manicured garden and letting all of it develop wild. They only have to pay shut consideration to what’s rising on their properties, promote native plant species, and cull invasive species—which might be quickly recognized utilizing cellular apps equivalent to iNaturalist and PictureThis. Invasive species don’t simply compete with and kill off native vegetation; since animals evolve in tandem with the native vegetation round them, invasive species are additionally a significant contributor to the world’s declining chook and pollinator populations. Mizejewski stated that by selling native vegetation and eradicating invasive species, on a regular basis property house owners could make an actual, constructive influence on their native environments. A latest research by Dr. Desirée L. Narango of the College of Massachusetts Amherst helps his declare.
Narango’s group studied the impact of native plant focus on native chickadees. They took lots, slightly below 2 acres in dimension, and divided it into yards of 0.25 to 0.4 acres. Narango’s group discovered that yards containing at the very least 70 % native vegetation supplied sufficient meals and shelter to help rising chickadee populations. Yards, the place invasive species have been extra dominant, didn’t.
Narango stated that her research reveals that selling native vegetation, even in small yards, can have noticeable, constructive, environmental results. The advantages exhibited by her experiment, she contends, spotlight the necessity to break down limitations inhibiting environmentally pleasant yard administration—one thing that is likely to be at odds with many Owners Associations (HOA), which require turf garden protection, limit the expansion of native plant species, and mandate using environmentally dangerous fertilizers and pesticides.
Mizejewski and Narango each argue that HOA laws that limit constructive yard administration should be struck down, or modified to accommodate native species. Narango additionally encourages shoppers to demand that their native retailers promote extra native plant species, and cease promoting invasive species, particularly these banned by state laws, equivalent to burning bush.

“Each time that I am going into Dwelling Depot, I complain,” Narango advised The Each day Beast.
Regardless of the obstacles, Mizejewski asserts that actual progress has been made. The NWF’s Licensed Wildlife Habitat program rewards property house owners, colleges, and communities for sustainable yard-care practices. Twenty-two years in the past, when Mizejewski started working on the NWF, there have been solely round 24,000 Licensed Wildlife Habitats. At present, greater than 279,000 personal properties, 10,000 colleges, and 148 communities have been licensed. In 2021, the NWF additionally established a Backyard for Wildlife program, which permits clients to purchase native plant collections on-line and have them shipped proper to their door. Up to now, 12,000 native plant collections have been bought, and gross sales in 2022 are up 400 % for the reason that program’s launch yr.
Nonetheless, extra must be carried out. Whereas evangelical about the advantages of particular person effort, Mizejewski admits that to actually flip the tide of world environmental change, collective effort is required.
“The extra folks [utilize sustainable yard-care practices], the extra influence we’ll have,” stated Mizejewski. “If I do it, it’s nice. I would feed some birds which can be flying by, and a monarch butterfly may land on my milkweed … but when all of us do it, even at a small degree, we are able to exponentially enhance the quantity of habitats within the human-dominated panorama, our cities, our cities, our neighborhoods.”
