Pollinator & Habitat Initiatives

In Rosemount, we are lucky to be home to the federally endangered and Minnesota state bee, the Rusty Patched Bumble Bee. Additionally, Dakota County is home to 125 rare species of plants and animals listed as of special concern, threatened, or endangered by the State of Minnesota or Federal Government. The City of Rosemount has initiated several pollinator and habitat conservation programs we encourage residents to take part in. A few are listed below.  

  1. No Mow May
  2. Pollinator Resolution
  3. Support Pollinators

No Mow May for 2023 has ended.  All Participating residents must mow lawns to be compliant with the City lawn height standard of 8 inches or less by the end of the day on 11.  The City will resume inspection and enforcement on lawn height starting June 12.  See the tips section below for advice on getting your lawn back to normal heights.  Check back in spring of 2024 to participate.

About No Mow May

May can be a tough time for pollinators. Many, including bees, are emerging from winter hibernation at a time of year when there isn't a lot of food and cover. One way we can help pollinators through this difficult time is to press pause on mowing in May. You may have a few more dandelions, but you'll also have more bees! Studies have shown suspending mowing in May can increase the number and diversity of bees.  

The City Council recently enacted a resolution proclaiming No Mow May. In support of No Mow May, the City will be temporarily suspending enforcement of lawn height ordinances for the month of May on occupied residential properties in good standing.  The City will resume enforcement of lawn height ordinances on Monday June 12th, 2023.  

How to Participate

The City asks that residents wishing to participate in No Mow May fill out a registration form and place a sign in their yard/window annually.  Now Mow May 2023 has ended.  The registration form will remain closed until spring of 2024.

Tips for a Successful No Mow May

Sometimes doing nothing, like delaying mowing for a month, isn't as easy as it sounds.  We've put together the following tips to help you have a successful No Mow May.  Check back from time to time; we'll update tips as questions arise throughout May.  

Problem: Help! It's June, and I can't get my mower through my jungle lawn!
Solution 1:  Delay fertilizing your lawn until after No Mow May is done.
Solution 2:  Mow your lawn before June. Mowing less often than you normally would will still allow some early spring blooming flowers into your lawn.
Solution 3:  Rent a heavy duty mower in June when it's time to mow.
Solution 4:  Make multiple passes with your mower.  Set your mower deck as high as you can for the first pass and go slow. Lower your mower deck for the next pass. Repeat until you get to the desired lawn height. Wait a couple of days between passes if you will be removing more than 1/3 of your grass height to prevent injury to your lawn.  
Solution 5:  If you have a mulching mower, consider discontinuing use of the mulching function and add the chute to your mower for the first time you mow in June. This helps reduce the chances that your mower will get bogged down and kill. It is really important if you use a chute when you mow to aim the chute away from roads, sidewalks, and driveways. This will reduce the amount of grass clippings that get in the road and reduce cleanup. Grass clippings left in the road wash into stormdrains when it rains where they clog drains and cause street flooding or wash into local ponds and cause algae blooms when they break down.

Problem:  Help! The dandelions have taken over! I wanted to help the bees, but this is not what I had in mind.
Solution 1:  Mow before the flowers set to seed. Many of the early-blooming lawn flowers are annuals, they only live one season. Mowing after they bloom but before they go to seed prevents them from taking over your lawn but sill allows pollinators access to food.
Solution 2:  Add some early spring blooming native plants to your garden and skip participation in No Mow May. Here's a list to get you started: Pasque Flower, Red & Yellow Columbine (other varieties are not native to MN), Wild Geranium, Bellwort, Prairie Smoke, Wild Blue Phlox, Jacob's Ladder, Early Buttercup, Bird's Food Violet, Prairie Violet, Common Blue Violet, Heart-leaved Golden Alexanders, and Golden Alexanders. Don't forget about early flowering shrubs like Elderberry, Snowberry, Juneberry, and Black Chokeberry.  

Problem:  Help! My neighbors are giving me the evil eye because of all the dandelions in my yard.
Solution 1:  Consider limiting the area of your yard that you don't mow to areas not easily seen by your neighbors.  This could be a fenced in backyard or an area screen by some shrubs.  Every little bit helps.
Solution 2:  Maintain a mowed buffer or maintenance strip between your yard and any neighbors.  This would be a width of 1-2 passes with the mower that your would mow on your normal summer schedule.
Solution 3:  Mow before the flowers set to seed. Many of the early-blooming lawn flowers are annuals, they only live one season. Mowing after they bloom but before they go to seed prevents them from taking over your lawn but sill allows pollinators access to food.
Solution 4:  Add some early spring blooming native plants to your garden and skip participation in No Mow May. Here's a list to get you started: Pasque Flower, Red & Yellow Columbine (other varieties are not native to MN), Wild Geranium, Bellwort, Prairie Smoke, Wild Blue Phlox, Jacob's Ladder, Early Buttercup, Bird's Food Violet, Prairie Violet, Common Blue Violet, Heart-leaved Golden Alexanders, and Golden Alexanders. Don't forget about early flowering shrubs like Elderberry, Snowberry, Juneberry, and Black Chokeberry.  

Problem:  I'm worried about ticks. What can I do?
Solution 1:  Deer Ticks, also called Blacklegged Ticks, the kind of ticks that can spread Lyme Disease, tend to live in wooded brushy areas. If you don't have that kind of habitat in your yard, your risks may be low. If you do have have a lot of brushy habitat in your yard, or if you've had problems with ticks in the past, we recommend adding some early spring blooming native plants to your garden instead of participating in No Mow May. See the list above.
