Creating Wildflower Meadows from Scratch or by Simply Changing Mowing Regimes

When a land steward asks for recommendations for increasing the number of pollinators in their landscape, many times the initial request is to start a pollinator meadow from seed. Their vision is usually a diverse meadow with an emphasis on native flowers and grasses. These meadows not only provide nectar and pollen as food for our native pollinators and beneficial insects, but also provide nesting and overwintering habitat in the stems, bunch grasses, and undisturbed ground. We love successful wildflower meadows started from scratch because they can have a high diversity of native species, can be showy with continuous blooms, and promote beauty in natural areas, backyards, and on farms—and even support agritourism.


This photograph shows a flowering meadow on the edge of an orchard. The flowers include tall dark-purple flowers, lower growing pale-purple flowers, and darker pink blooms beyond. In the distance can be seen green forest covering gently sloping hills. The sky has white and pale gray clouds.

The tall plant in the foreground is ironweed, around it is bergamot, and in the background is joe pye weed.

When starting from scratch, however, it’s important to note that during the first couple of years of establishment, it’s not all flowers and butterflies. To learn about some of the detailed methods and timelines used, download a copy of the Xerces publication Organic Site Preparation for Wildflower Establishment.

In towns and cities, a growing number of gardeners are converting mowed lawn to pollinator habitat. On farms, it is common to begin with old hay lands that are mowed less frequently. These sites are dominated by non-native grasses and tend to have thick, mat-forming root systems with lots of thatch and residue on the surface. Aggressive site preparation is needed before sowing tiny native seeds into the prepared soil surface. Some of the native perennials take up to three years before flowering. Funding is also a consideration. It isn’t exactly cheap to buy high-quality, locally adapted native seed, as well as the other materials needed to prepare the site. It’s hard work, but when all these steps are taken, starting from scratch can yield glorious results for years to come. It has made many pollinators, larger wildlife, and humans overjoyed across the United States!

The project is at Hillside Village in Keene, NH, which received a Conservation Opportunity Fund through Cheshire County Conservation District. The Hillside Village is also the recipient of a Northeast monarch habitat kit from the Xerces Society. (Photo: Marty Post, Hillside Village.)


Many times though, landowners don’t have necessary funding or labor hours to put towards from-scratch pollinator habitat projects. They are interested in helping pollinators, but might have a larger landscape to manage and are looking for more casual methods that are affordable over a larger scale. If there is already the beginning of decent pollinator habitat in a system, a suitable option is to change the mowing regime—which may be as simple as to not mow it during the summer months and wait to mow after a frost or two in the autumn. Over time, existing flowering plants that are already present in the soil will begin to increase.


This photograph shows flowers blooming along the edge of an orchard. The flowers include the white disk-shaped flower heads of Queen Anne’s lace and dark-pink ball-shaped flower heads of red clover. An orange-and-black monarch butterfly is resting on one of the clover flowers. In the distance can be seen green forest covering gently sloping hills. The sky has white and pale gray clouds.

The flowers included non-native red clover and Queen Anne’s lace as well as self-sown native blackberries, common milkweed, spiraea, pale-spiked lobelia, and showy tick-trefoil.

Habitat areas managed by delayed mowing may not exhibit the same diversity of native plants as a from-scratch meadow. For example, there may be a prevalence of introduced species such as Queen Anne’s lace and red clover in areas previously managed by humans. At the same time, native pollinators such as bumble bees and monarch butterflies forage on non-native red clover flowers. Delayed-mowing meadows may result in less flower diversity, but can still provide meaningful pollinator value in areas with just a simple change of the mowing regime. Ideally, sites would mow about one-third of the acreage per year on a rotational basis: Since native invertebrates overwinter in the stems and bunch grasses, two-thirds of the area may be left undisturbed while one-third is mowed to reduce woody encroachments and maintain open pollinator habitat.

This area is managed with a rotational delayed-mowing regime to maintain open characteristics for pollinators and ground-nesting birds. In mid- to late-summer the abundance of goldenrod and common milkweed is abuzz with bees and flitting monarchs. (Photo: Alina Harris.)

Your local USDA Natural Resources Conservation Service field office can also help if you are interested in establishing new pollinator habitat or changing your mowing regime to increase flowering diversity on private land. Reach out to your local NRCS field office to start the conversation and potentially receive funding towards your conservation efforts.
