Every spring, yard signs start popping up across neighborhoods in Eau Claire, Chippewa Falls, Woodbury, and River Falls announcing that the homeowner is “giving the bees a break” by not mowing in May. It’s a well-intentioned idea — and as a lawn care, landscape, and pest control company that’s been serving western Wisconsin and eastern Minnesota since 1978, we fully support the goal of protecting pollinators.

But after nearly 50 years of caring for northern lawns, we’ve learned that the story around No Mow May is more complicated than a yard sign lets on. Several of the assumptions behind the movement simply don’t hold up to scientific scrutiny, and in our northern climate, skipping a month of mowing can actually work against both your lawn and the pollinators you’re trying to help.

Here’s an honest look at the most common No Mow May myths — and what you can do instead to genuinely support biodiversity in your Wisconsin or Minnesota yard.

Where No Mow May Came From

No Mow May was created by the UK conservation charity Plantlife and was later popularized in the United States by Appleton, Wisconsin, which adopted the concept in 2020 and made it a permanent city policy in 2022. The original research that helped drive national adoption was conducted in Appleton itself.

That research has since been retracted, and many of the country’s leading turfgrass scientists, entomologists, and wildlife organizations… including voices at the National Wildlife Federation … have moved away from blanket No Mow May messaging in favor of what they call “Grow Beyond No Mow May”: a smarter, season-long approach to pollinator-friendly landscaping.

With that context in mind, let’s walk through the myths.

Myth #1: “Not Mowing for a Month Creates a Meadow for Pollinators”

The reality: A neglected lawn is not a meadow.

A true pollinator meadow is a deliberately designed ecosystem of native wildflowers, grasses, and habitat structure. What actually grows in an unmowed Wisconsin or Minnesota lawn for 30 days is mostly the same turfgrass you already had along with whatever happens to be in your local seed bank. In most suburban yards around Eau Claire or Woodbury, that seed bank contains aggressive non-natives like crabgrass, creeping charlie, and barnyard grass, plus regional invasives like garlic mustard and musk thistle.

Native prairie wildflowers… coneflower, wild bergamot, prairie clover, butterfly milkweed… don’t spontaneously appear just because you park the mower. If your property wasn’t recently a remnant prairie, those seeds aren’t in the ground waiting.

Myth #2: “Longer Grass Feeds the Bees”

The reality: Turfgrass itself offers very little to pollinators.

Kentucky bluegrass, fescue, and ryegrass… the species that make up most lawns across the Chippewa Valley and Twin Cities east metro… are wind-pollinated. Their flowers produce no meaningful nectar and almost no pollen that bees can use. Letting them grow tall doesn’t create bee food; it just creates tall grass.

The pollinator value people associate with No Mow May actually comes from the weeds that flower during the month… dandelions, clover, self-heal, and creeping charlie. And here’s the catch: research summarized by University of Wisconsin Extension found that lawns mowed on a two-week schedule at a higher blade height actually hosted more pollinator activity than lawns mowed every three weeks or left entirely unmowed. When grass gets very tall, pollinators have a harder time accessing the low-growing flowers underneath it.

Myth #3: “It’s Good for the Lawn to Take a Break”

The reality: In our region, May is one of the worst months to skip mowing.

In western Wisconsin and eastern Minnesota, May is when cool-season turfgrass hits its peak growth rate. Temperatures are ideal, spring rains are frequent, and the grass is putting on significant vertical growth every week. Skip mowing for a full month and you’re looking at grass that can easily reach 8–10 inches or more.

That creates several real problems:

• The one-third rule gets violated. Turf experts agree that you should never remove more than one-third of the grass blade in a single cut. Going from 10 inches back down to a normal 3–3.5 inches means scalping the lawn… which stresses the crown, invites disease, and often leaves the turf yellow and thin for weeks afterward.
• Thatch, disease, and matting increase. Tall, wet spring grass mats down, traps moisture, and creates ideal conditions for fungal issues… something our technicians already watch for in Wisconsin lawns during humid spring weather.
• The “recovery cut” is brutal on your mower and your yard. You’re often looking at bagging heavy clumps of wet clippings and making multiple passes… hardly the low-effort, low-carbon-footprint outcome the movement promises.

The environmental benefit of a properly maintained lawn… erosion control, stormwater absorption, carbon sequestration, and cooling… depends on the lawn being healthy. A stressed, scalped, patchy lawn in June provides none of those benefits.

Myth #4: “Taller Grass Doesn’t Cause Pest Problems”

The reality: In the upper Midwest, longer spring grass changes the pest picture… and not always in helpful ways.

Tall, dense vegetation creates the cool, humid microclimates that rodents like voles use as cover, and it can provide better habitat for certain nuisance insects. In Wisconsin and Minnesota, where tick populations have been expanding in recent years, the edges where tall grass meets wooded or shrubby areas are exactly the transitional zones where tick activity is highest.

This matters especially for families with kids and pets, and for homeowners on larger lots near woods, lakes, or wetlands… which describes a lot of properties we service across the Chippewa Valley, the St. Croix River area, and the Twin Cities eastern suburbs.

Myth #5: “You Have to Choose Between a Nice Lawn and Helping Pollinators”

The reality: This is the biggest myth of all… and the one we’re most passionate about correcting.

You absolutely do not have to let your yard go wild for a month to support pollinators. In fact, a thoughtful landscape plan will do far more for local wildlife than 30 days of neglect ever could, and it’ll look great year-round. Here’s what actually works in our Wisconsin and Minnesota climate:

Mow smarter, not less. Raise your mower deck to 3.5–4 inches. Taller blades shade out weeds, develop deeper roots, need less water, and tolerate our summer heat far better than short-cut turf.

Plant a dedicated pollinator bed. Even converting a 10-by-10 corner of your yard to native perennials — purple coneflower, black-eyed Susan, wild bergamot, milkweed, New England aster, little bluestem — creates more pollinator value than an entire unmowed lawn. And unlike an unmowed lawn, it looks intentional and beautiful.

Add low-growing flowering plants to the lawn itself. Dutch white clover, self-heal, and creeping thyme tolerate mowing, fix nitrogen (clover), provide consistent bloom from spring to fall, and give bees a food source throughout the whole season — not just a two-week window in May.

Create real habitat structure. Leave a brushy corner, install a small log pile, keep some leaf litter in garden beds over winter, and plant native shrubs like serviceberry, nannyberry, or red-twig dogwood. Native bees, in particular, need nesting habitat… not just flowers.

Cut back on broadcast pesticide applications. This is something we take seriously at Green Oasis. Our lawn care programs are built around targeted, as-needed treatments rather than blanket spraying, and our pest control work is focused on keeping homes protected without unnecessary chemical exposure to the broader yard.

A Middle Ground That Actually Works

If the spirit of No Mow May appeals to you… slowing down, doing less damage, making room for wildlife… there’s a much better version of it you can practice all season long, one that’s well-suited to the growing conditions in Wisconsin and Minnesota.

Call it “Mow Less, Plant More.” Keep your primary lawn areas healthy and well-maintained. Convert a portion of your yard to a native pollinator garden or low-mow clover blend. Leave a deliberate “wild edge” along a fence line or tree line. Water deeply and infrequently, fertilize responsibly, and let clover and self-heal coexist with your turf.

That’s a landscape that supports pollinators, looks cared-for, protects your property value, and holds up to the realities of a Wisconsin or Minnesota summer. It’s also the kind of thoughtful, customized approach we’ve been delivering to homeowners in Eau Claire, Chippewa Falls, River Falls, Hudson, Rice Lake, Woodbury, Stillwater, Lake Elmo, and Cottage Grove for more than four decades.
