WORX: Everything You Need To Know Before Installing A No Mow Lawn

With energy costs on the rise and climate challenges constantly in the headlines, homeowners are increasingly looking for ways to conserve resources by treading lightly. In recent years the no-mow movement has gained popularity as a way to support wildlife, reduce negative impacts on the environment, and boost free time. Whatever the motivation, most of us can agree that not having to mow is a benefit unto itself.

A few years back, “No-Mow May” began as a citizen science initiative to explore what would happen if we delayed our first mowing of the season for an extra month. When the results came in, massive increases in pollinator abundance and diversity were noted for the non-mowed yards compared to yards that had been mowed as usual.

But getting back to the normal routine after a month of neglect comes with a strenuous lawn cleanup and may leave a stressed out lawn in its wake. Some experts worry that the weakened state of an unkempt lawn, where weeds have been allowed to flower, becomes a recipe for a net increase in chemical usage as owners re-tame their yards. There may be a better alternative.

Way before the trendy month-long mowing holiday was conceived, gardeners, horticulturalists, and wildlife enthusiasts were experimenting with grasses and groundcover plants that thrived without mowing. Whether the goal is to establish a backyard habitat, to create a one-of-a-kind landscape design, or simply to shorten the weekly to-do list, installing a no-mow lawn offers a great variety of benefits.

What is a no-mow lawn?

A no-mow lawn is a low maintenance, drought tolerant, wildlife friendly alternative to traditional turfgrass. These spaces typically include dozens of plant species, including warm and cool season grasses, perennial groundcovers, and wildflowers. No mow lawns typically grow 8 to 12 inches high, with a wild appearance reminiscent of a meadow. They offer a host of benefits for homeowners and their local wildlife, like reducing time and money spent on landscape maintenance, and increasing habitat diversity.

What are the pros and cons of installing a no-mow lawn?

This style of lawn is not for everyone. Planting a no-mow lawn comes with both pros and cons.

Pros

  • Eliminates most lawn work throughout the year
  • Reduces air and water pollution
  • Conserves soil, water, and nutrients
  • Fosters a diverse ecosystem of native pollinators, birds, and other wildlife.
  • Protects stream banks and lakeshores from erosion.

Cons

  • Annual maintenance mowing is more difficult than mowing a conventional lawn.
  • Attracts some unwanted wildlife, like rodents, snakes, and ticks
  • May not comply with HOA or municipality rules
  • Could become a fire hazard if not properly maintained

When is the best time to plant a no mow lawn?

In most of the United States, late summer or fall is the best time to plant a no-mow lawn. Mild sunny days and cool nights support seed germination and root growth, and the roots will continue to grow and develop well into fall until the ground freezes. This gives the lawn an excellent head start before the stress of heat and drought the following summer.

Should I convert my whole yard to no-mow lawn?

Converting an established turfgrass lawn to no-mow is a major undertaking that should be thoroughly planned before starting. It’s important to think about how you currently use the space, and how those activities will be affected. High traffic areas and children’s play areas may actually function best with some amount of mowed turfgrass. Also consider the very real attraction that no-mow holds for all kinds of wildlife, including insects and animals that you may not want close to the house.

One of the worst mistakes you could make would be to spend time and money on a total landscape renovation, only to find out that it doesn’t work for your lifestyle. For most homeowners it is best to begin by converting an unused part of the lawn away from the house, while continuing to maintain a mowed lawn closer to the house. If you like the change, add more no-mow space in following years.

What kinds of plants work as no-mow lawns?

Grass seed and sod companies offer products with names like “No Mow Blend” that feature a mix of durable low-growing grass species. However, a no-mow lawn can include dozens of low growing grass, perennial, and annual species that tolerate foot traffic, thrive with only natural rainfall ( once they are established), and require minimal maintenance. Locally native plants often play an important role in no-mow applications because they thrive in the available growing conditions and support local wildlife.

A few popular no-mow lawn plants

  • Cool season grasses: hard fescue, chewings fescue, sheep fescue, and creeping red fescue
  • Warm season grasses: blue grama, buffalo grass,
  • Perennial ground covers: Corsican mint, creeping sedum, creeping thyme, white Dutch clover
  • Perennial and self-sowing annual wildflowers: aster, black eyed Susan, butterfly milkweed, yarrow

How do I maintain a no-mow lawn?

Although these lawns are billed as “no-mow,” they perform best with an annual or twice yearly trim. In early spring, before new growth begins in earnest, use a lawn mower or string trimmer to cut dead stems and foliage to 4 or 6-inches high. Clear away any clumps of clippings to avoid smothering the emerging new growth. In areas that receive heavy snowfall, it may be desirable to minimize snow mold damage by cutting the foliage back to 6-inches after the stems die back in late fall or early winter.

Although they are semi-wild spaces, no mow areas are susceptible to invasion by undesirable plants. Throughout the growing season, monitor the lawn for encroaching tree seedlings or aggressive weeds and vines. Stay vigilant and pull, cut, or spray weeds before they flower or set seeds.

If you’re looking for a simple way to manage your landscape that shortens your chore list, reduces your carbon footprint, and increases habitat for backyard wildlife, then a no-mow lawn could be a good fit. And it’s not an “either/or” choice. No-mow complements conventional turfgrass when it is used to transition from heavily used lawn areas to more natural areas. It’s a great way to bring nature closer to home.
