Protecting Pollinators at the ACD Office

Plant species that are "native" to a local area (i.e., grow there naturally) provide necessary food and habitat for pollinators and enhance soil and water quality. Outdoor spaces that are in covered in turf provide very few benefits to pollinators or the environment, so frequent pockets of natural spaces are critical in developed areas. We recently converted part of our office property from an area that was annoying to mow into beneficial pollinator habitat! Here's how we did it:

In early summer, we used "sheet mulching" to kill off the grass and weeds. If you can plan to have a couple of months before planting, this is an easy method to prepare a site without using herbicides. The future garden space was fully covered in cardboard sourced from our local recycling facility and then covered with a couple inches of mulch. This effectively smothered existing weeds.

We selected 11 native wildflower species, 2 native shrub species, and 2 native grass species for the garden that will thrive with the amount of natural sun and water that the spot gets. Adding wildflowers is a no-brainer to provide nectar for pollinators, but adding grasses sometimes gets overlooked in pollinator gardens. Native grasses provide homes for insects to overwinter in and add beautiful texture to a space! There are many great places to order native plants from in Minnesota; we used Minnesota Native Landscapes and Glacial Ridge Growers.

Since our garden is next to a sidewalk, it was lined with river rock to create a cleaner look and contain the mulch. 

In early fall, the plants arrived and were planted. By this time, the cardboard underneath had broken down enough that it was easy to rip gaps in it to dig holes for the plants. Autumn planting gives plants an edge for developing strong roots in their new home and is a great option if you miss the spring planting window. The plants were spaced about 1.5 feet apart to leave them with room to grow into their full-sized forms. The already-present mulch will help hold in water and continue to suppress weeds.

It will be exciting to watch these new plants grow over the coming year to create a beautiful spot that will support some of our essential pollinator species in Anoka County.

You can also follow these steps to convert areas of your property that may not get much traffic or are hard to mow into a space that will benefit everyone!
