Several studies have been conducted on low-maintenance turfgrass species; however, relatively few have evaluated mixtures or blends. The objective of this study was to evaluate low-maintenance turfgrass mixtures or blends for turf quality under minimal input conditions. Eight turfgrass mixtures or blends were planted in 2009 at the University of Minnesota Landscape Arboretum (Chaska, MN) on a low-fertility soil to assess their adaptability to low-input conditions (minimal water and fertilizer and no pesticides after establishment). The year after establishment, plots were divided into no-mow and minimal mow treatments. Plots were evaluated for establishment in 2009 and overall quality and percent weed cover in 2009, 2010, and 2011. Native grass mixtures established slowly with greater weed encroachment, but over time resulted in high-quality ratings. Under minimal mowing, the Tall Fescue Blend [tall fescue (Festuca arundinacea)] performed the best for quality, while three fine fescue (Festuca sp.) mixtures and the Tall Fescue/ Kentucky Bluegrass Mixture [tall fescue D kentucky bluegrass (Poa pratensis)] also had acceptable quality ratings. The Kentucky Bluegrass Blend (kentucky bluegrass) was less competitive with weeds and had unacceptable quality ratings. Under no-mow conditions, the native grass mixtures and the Tall Fescue Blend had the highest overall quality ratings.
