URGENT UPDATE: As the climate crisis intensifies, homeowners across the United States are urgently transforming their lawns into low-water landscapes. In Littleton, Colorado, residents like Lena Astilli are leading the charge, embracing xeriscaping to combat water scarcity in the wake of rising temperatures and prolonged drought conditions.
Astilli, who previously replaced grass in her backyard with native plants, is now tackling her front yard. “A monoculture of Kentucky bluegrass is not helping anybody,” she emphasized. With the average American family using 320 gallons (1,211 liters) of water daily, nearly one-third of which is dedicated to outdoor use, the need for sustainable landscaping has never been more critical.
Officials confirm that traditional lawns are unsustainable in arid regions like the American West. As climate change exacerbates drought conditions, maintaining lush green lawns is jeopardizing already stressed freshwater supplies. The concept of xeriscaping—coined by Denver Water in 1981—focuses on using drought-tolerant native plants to significantly reduce irrigation needs.
Mark Richardson, executive director of the Ecological Landscape Alliance, stated, “Lawn reduction is a fantastic way to limit the use of water in the landscape.” He warns that the situation will worsen as potable water becomes increasingly scarce. By minimizing lawns, homeowners can also reduce pesticide runoff and create habitats for declining pollinator populations.
The urgency of this trend is underscored by the environmental benefits it offers. “We can bring nature back into our urban and suburban areas,” said Haven Kiers, an associate professor at the University of California-Davis. “Improving biodiversity is going to be huge for the environment.” Not only does this shift support wildlife, but it also promotes mental well-being. Gardening and spending time outdoors are proven to enhance physical and mental health.
Taking the first steps toward xeriscaping may seem daunting, but experts suggest starting small. Kiers advises homeowners to gradually replace sections of lawn with native plants, flowers, and shrubs, reducing costs and labor. Financial incentives and rebates are also available in several states, making these transformations more accessible.
As Astilli continues her landscaping project with assistance from designer Eryn Murphy, she’s excited about the possibilities. They are replacing traditional grass with native species like bee balm, evening primrose, and prairie dropseed. “Really, the sky is the limit in terms of your creativity and your aesthetic,” Murphy noted.
With climate change making traditional lawns increasingly untenable, residents are being urged to rethink their landscaping choices. “Water is going to keep getting more expensive,” said Murphy. “You’re going to have to open your eyes and say, what could I do that’s different and better?”
This growing trend reflects a significant shift in how homeowners view their outdoor spaces, making xeriscaping not just a practical choice but an essential response to an urgent environmental crisis.
Stay tuned for more developments as this movement gains momentum across the country.
