Responding to public pressure to reduce synthetic chemical use and combating the rise of herbicide resistance in amenity grasslands are challenging due to the lack of alternative options. Additionally, the changing climate is less conducive to traditional grassland species success. The ability to rapidly renovate grassland surfaces could provide solutions to both challenges by reducing weed seed pressure and establishing genetically improved, well adapted varieties. Fraise mowing is an aggressive cultivation practice designed to harvest verdure, organic matter, and soil to a depth of 5 cm while allowing turfgrass to reestablish from unharvested rhizomes or provide an advantageous seedbed for establishing via seed or sod. Given the weed seed bank accumulates near the soil surface in no-till systems, we hypothesized fraise mowing could be an effective means of weed seed bank harvest and long-term, non-chemical weed control. Field experiments were conducted from 2017 – 2019 at the Vineyard Golf Club (Edgartown, MA) in low-maintenance, naturalized fine fescue rough heavily infested with smooth crabgrass (Digitaria ischaemum (Schreb.) Muhl.). Three weed seed bank harvest depths and two grassland establishment rates across five timings were evaluated for preventing weed re-infestation. Prior to fraise mowing, soil cores were collected from the study area and subjected to seedbank analysis. Similarly, seedbank analysis of harvested fraise mow debris was completed to determine efficacy of weed seed harvest. Despite a substantial reduction in the smooth crabgrass weed seed bank and a significant effect of timing and harvest depth on re-infestation, smooth crabgrass surpassed thresholds (<15%) by the end of the first full growing season, indicating the need for additional follow-up treatments for commercially acceptable control.
