S3 E44 Frequent Irrigation Increases Turf Quality and Weeds.
In this video, I examine the research by Cain et al. (2022) that explores how varying irrigation schedules affect the encroachment of annual bluegrass (Poa annua) into perennial ryegrass turf systems in western Oregon. The study reveals that watering once per week significantly reduces annual bluegrass encroachment compared to irrigating four times a week, and that replacing irrigation volumes based on reference evapotranspiration (ETref) had no meaningful impact on that outcome
Throughout the video, I walk viewers through the experimental approach, highlight the implications for turfgrass managers aiming to suppress undesirable bluegrass without altering evapotranspiration-based irrigation schedules, and reflect on how this insight might inform more water-efficient lawn or turf maintenance strategies.
