Abstract/Contents:"Mixtures of Kentucky bluegrass (Poa pratensis L.) and cold-tolerant bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt Davy], sometimes referred to as "bluemuda", have received interest from turfgrass managers in the transition zone of the United States as a means of maintaining green turf in cold weather without overseeding. The objectives of this research were to develop methods of establishing a Kentucky bluegrass/bermudagrass mixture, determine species fluctuations throughout multiple growing seasons, and to examine winter survival of bermudagrass in Pennsylvania. Two experiments were conducted in two locations, University Park and Reading, PA. The first experiment was initiated in June of 2020 and involved establishment of Tahoma-31 bermudagrass by placement of sprigs in strips or distributed randomly into plots of 1-yr-old HGT Kentucky bluegrass following aeration and slicing. The second experiment involved slicing "Tahoma-31" sod, followed by seeding "HGT" at 14.6 and 29.3 g m-2 in Sept. 2021. All experiment areas were mowed at 2.54 cm. Percent ground cover and fluctuations in species composition for all treatments in experiments were monitored over two years using digital photography, tiller counts, and visual ratings. Results indicate better stand uniformity and seasonal species transition following seeding Kentucky bluegrass into an existing stand of bermudagrass when compared with sprigging bermudagrass into Kentucky bluegrass. Shifts in species dominance were dramatic according to season and over multiple years, even in the absence of subsequent overseeding. Winterkill of bermudagrass was not observed at the Reading location, but some injury occurred in University Park on bermudagrass that was not covered."
