‘Greener’ options for grass sprout up

Grass isn’t always the best groundcover for a yard: It’s thirsty at a time when water is becoming more scarce; it attracts fewer pollinators; it requires expensive chemicals to maintain; and it must be disposed of if you bag as you mow.

That’s why many property owners are downsizing their lawns or simply eliminating turf grass in exchange for something more functional and less demanding.

“We’re recommending ecosystem changes provided by a more productive landscape, instead of a monoculture from grass,” says Susan Barton, an extension horticulturist with the University of Delaware. “A lawn should not be a default vegetation, but it should be more purposeful. More diverse.”

She suggests four alternatives to turf grass: landscape beds, meadows, woods and paved, permeable hardscapes.

“All of these provide more ecologic service,” she says. “We’re talking clean water. More habitat for insects. More oxygen taken in and less carbon dioxide given off.”

Barton helped get a New castle County, Del. landscape ordinance passed a decade or so ago allowing “managed meadows” to replace grass in residential front yards. These no-mow areas filter water, encourage the return of native plants that provide food and cover for wildlife, and still have curb appeal.

“A managed meadow isn’t simply a matter of letting your grass grow long,” she says. “It means mowing paths through it and adding edges where needed. If people think about it and make it look good, there’s no reason why it shouldn’t be part of suburbia.”

Downsizing or replacing turf isn’t simple or cheap, but it can be done in stages. Start with your toughest-to-grow or hardest-to-mow sections.

“Use the 80-20 plan where 20 percent of your area requires 80 percent of your maintenance,” says Evelyn Hadden, a founding member of the Lawn Reform Coalition and author of Beautiful No-Mow Yards (Timber Press, 2012).

Other replaceable options include boulevards, driveways and pockets overgrown by weeds or moss.

“Look first at areas where the grass is already suffering - that strip along the street that’s hard to water or trampled by people getting off the bus,” says Pam Penick, a garden designer from Austin, Texas, and author of Lawn Gone!: Low-Maintenance, Sustainable, Attractive Alternatives for Your Yard (Ten Speed Press, 2013).

Or “consider ornamental grasses,” she adds, or “some of the new groundcovers [aromatic herbs, succulents, low-growing shrubs, ferns, hosta]. Edibles. Larger shrubs. You can have a nice looking yard yet be conservation-minded.”

Any lawn renovation project should be regionally appropriate, however.

“What we’re really talking about is using native vegetation,” says the University of Delaware’s Barton.
