Try to manage your lawn in a way that encourages health and vigor, which out-competes weeds and resists pests.
Eco-friendly lawns are sprouting up across America as property owners realize they can get better results for less work and money. Some are getting improved drought resistance, too.
“We have to change our mindset about what our lawns should be,” says Tom Tiddens, plant health care supervisor at the Chicago Botanic Garden. “Some people don’t want to see a weed in their lawn. Although adding broadleaf plants will change its (manicured) look, it also will attract pollinators and reduce the need for chemicals.”
Lawns, traditional or otherwise, need suitable environments in which to grow, but many homeowners don’t even know what kind of grass they have, Tiddens says.
“They may be growing lawns in places where it’s not going to work for them,” he says. “If they’re growing under maple trees, for example, they’re asking for trouble.”
A typical eco-lawn is a combination of turf grass varieties with broadleaf plants such as white clover, which supplies nitrogen to the roots, says Alec Kowalewski, a turf grass specialist with the Oregon State University Extension Service.
Yarrow can be added for drought tolerance, along with flowering plants such as baby blue eyes, English daisy, chamomile, California poppy and creeping thyme. They are tough enough to tolerate family activities, yet require less effort to keep up, he says.
“The kinds of turf seed used varies from location to location; for instance, perennial ryegrass in moderate climates, fine fescue in shady environments, tall fescue in warm, sunny areas,” Kowalewski says.
Both eco-lawns and regular lawns can be organic, “meaning you fertilize with organic products and don’t apply pesticides,” he says. “Both eco-lawns and traditional lawns require mowing.”
Homeowners can take the environmental middle ground if they don’t want to go completely organic, Tiddens says.
“Organic is a squishy word, anyway,” he says. “Anything we can do to reduce the use of pesticides and fertilizers makes things in the yard more friendly. Go to spot spraying rather than area-wide (chemical) applications.”

Even simple things can help. Consider:
Mowing height and frequency. Tall grass, or anything from 2.5 to 3.5 inches, needs less water. Mowing frequency depends on how much flowering is desired and whether rain has encouraged heavy growth.
Mulching. “Get a mulching mower,” Tiddens says. “You reduce the need for fertilizers by 20 percent by returning grass clippings to the ground.”
Chemicals. Only use pesticides or herbicides when pests or weeds are at a higher-than-desired level. Even then, limit their use.
Irrigation. Irrigate deeply and infrequently, about 1 inch of water per week.
Aerator. “An aerator pulls plugs from the soil of a lawn about the size of your thumb,” Tiddens says. “That helps improve rooting, irrigation, and improves the health of the lawn. It helps especially when you’re not dealing with good soils. It perks the lawn up.”
