SPRING ESTABLISHMENT OF CREEPING BENTGRASS AND ANNUAL BLUEGRASS ON PUTTING GREENS FOLLOWING SIMULATED WINTERKILL
In the springs of 2023 and 2024, two trials were conducted to evaluate spring establishment of creeping bentgrass (Agrostis stolonifera L.) and, annual bluegrass (Poa annua var. Reptans (Hauskn.)) on putting greens following simulated winterkill. Trial 1 in 2023 evaluated spring establishment on bare soil following sod removal from a putting green at 4 locations; Hancock Turfgrass Research Center (HTRC), East Lansing, MI; O.J. Noer Research Station, Verona, Wisconsin; Horticulture Research Station, Ames Iowa; and Turfgrass Research, Outreach, and Education Center (TROE), St. Paul, Minnesota. Trial 2 in 2023 and 2024 evaluated putting green establishment on an annual bluegrass putting green that had been sprayed with non-selective herbicide and interseeded at Hancock Turfgrass Research Center (HTRC), East Lansing, MI. Both trials consisted of evaluating timing of spring seeding: early, middle, or late spring seeding, and seed entry: four creeping bentgrass cultivars, ‘Penncross’, ‘Pure Distinction’, ‘Declaration’, ‘Penn A-4', and one annual bluegrass, ‘Two-Putt’, and a mixture of Pure Distinction and Two-Putt. All entries including the Pure Distinction and Two-Putt mix were seeded at 49 kg ha-1. In both Trial 1 and Trial 2, timing of spring seeding was significant for the first one or two measurement dates at the beginning of the study but would not drastically change when golf courses opened in the spring following winterkill. In both studies seed entry was significant but numeric differences in percent turfgrass cover were minimal.
