Stiltgrass Working Group
Stiltgrass is an extremely aggressive and destructive invasive grass that was first discovered in Scio Township in 2015. Once established, it quickly takes over, pushing out native plants and wildlife. The Stiltgrass Working group is a collaborative of private citizens, conservation organizations, and municipalities, all working together to control the threat of stiltgrass and prevent it from spreading beyond Washtenaw and Lenawee Counties.
Every year, the Working Group conducts a targeted outreach campaign to reach as many homeowners as possible. In 2019, we surveyed over 130 properties to map the spread of stiltgrass, and assist with treatment efforts. Input from the community is at the core of our work. We hope to keep everyone engaged and informed about this effort, and make our knowledge and resources as accessible as possible.

What Is Stiltgrass?
Stiltgrass is a prolific invader of natural areas, lawns, gardens, and forests. Each plant produces between 100 and 1,000 seeds These seeds will remain viable in the soil as a “seedbank” for up to five years. As a result, even if treated, the leftover seeds will continue to re-sprout each year until there are no seeds left. If left untreated, stiltgrass rapidly takes over anything it touches, turning lawns, gardens, and natural areas.
Although nothing eats stiltgrass— not even goats— the seeds are easily transported by deer, streams and rain, lawn mowers, and other human activities. For these reasons, it is critical that stiltgrass be detected early and treated as soon as possible to prevent it from spreading and establishing a large seedbank.
Several treatment options are available. In March and April, spray the infested area with pre-emergent herbicide such as Prowl to kill the seeds. Since stiltgrass spreads by establishing a “seedbank” in the soil, this is extremely effective and may prevent you from having to treat multiple years in a row. In late spring and summer, spray the plant with 2-3% glyphosate (Roundup or AquaNeat). Torching with a targeted weed torch is another effective solution. Finally, for small patches, hand-pulling is sufficient. Double-bag the plant and put it in the trash (not the compost).
If the cost, or the labor involved, concerns you, please contact us: we have cost-sharing options available to help make treatment easier!
