In this video, I dive into the article “Survey of Water Use and Management Practices on US Golf Courses from 2005 to 2024” published in HortTechnology (Shaddox et al., 2025). The study tracks nearly twenty years of changes in how golf courses across the United States use and manage water. I discuss how irrigation volumes and irrigated areas have shifted over time, highlight important regional differences, and explain why some water sources—like recycled water—are declining while others remain steady. I also cover the adoption of new management strategies such as moisture sensors, irrigation audits, and objective scheduling, along with the continuing challenges of infrastructure upgrades, regulatory pressure, and competition for water resources. If you’re interested in sustainability, turfgrass science, or the future of golf course management, this discussion will give you a clear look at the evidence and what it means moving forward.

In this video, I discuss the YouTube episode “Struggling Turf? Calcium Could Be the Missing …” and examine it through the lens of the strawman fallacy. We’ll look at how someone can present information that is technically true, yet still mislead by reframing the issue or knocking down an argument no one actually made.

This breakdown shows how a conman can be both truthful and deceptive at the same time—a powerful reminder of why critical thinking matters in turfgrass science, lawn care, and beyond.

In this video, I review the scientific article “Irrigation Frequency Affects Zoysiagrass Rooting and Plant Water Status.” We’ll look at how different irrigation schedules influenced root development and water relations in zoysiagrass, and what these findings mean for turfgrass management. If you’ve ever wondered how often you should water to encourage deeper roots and better turf performance, this study offers valuable evidence-based insights.

In this episode, I break down the claims made in “Check out These Roots, John Perry! | [LIVE PODCAST] Ep.8 of the Average Joe Lawn Care Show,” where the hosts argue that liquid aeration is an effective solution for lawn health. I dive into the science and present evidence that challenges their assertions. With years of turfgrass science experience, I explain why liquid aeration doesn’t deliver the promised results and why relying on this product could lead to misguided lawn care practices. Don’t fall for the hype – join me as I debunk the myths and set the record straight with evidence-backed facts!

In this video, I take a look at some of the recent comments and questions from TikTok and YouTube. Your feedback not only shapes the conversations we’re having here but also sparks deeper discussions about turfgrass science and management.

I’m also excited to introduce a new fundraiser supporting turfgrass research. Turfgrass plays a vital role in sports, recreation, and landscapes, yet research in this area often goes underfunded. Your support will help advance studies that improve sustainability, water use efficiency, soil management, and turf quality—work that benefits golf courses, sports fields, parks, and home lawns alike.

In this video, I explore the findings of the research article “Tall Fescue Rooting as Affected by Deficit Irrigation” (HortScience, Volume 42, Issue 3). The study, conducted by Jinmin Fu, Jack Fry, and Bingru Huang and published June 1, 2007, investigates how reduced irrigation impacts the rooting behavior of 'Falcon II' tall fescue grasses using minirhizotron imaging.

I’ll walk through:

The study’s experimental setup using varying levels of evapotranspiration (20%, 60%, and 100%) Key findings such as the surprising increase in root length and surface area under severe water stress (20% ET) Practical implications for turfgrass management and water conservation strategies

Whether you're working in turfgrass management, water-efficient landscaping, or just curious about plant responses to water stress, this video unpacks the science and its real-world applications.

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.

In this video, I discuss the scientific article "Irrigation Rates and Frequency Affect Tall Fescue Color and Weed Encroachment." We’ll examine how adjusting irrigation amounts and timing influences turfgrass aesthetics and weed pressure. From water conservation to maintaining turf quality, this study provides valuable guidance for anyone managing tall fescue under variable moisture conditions.
