In this episode of Turfgrass Epistemology, I respond to viewer comments and emails covering some of the most common questions and misconceptions I see about turfgrass science, soil fertility, nutrient management, and disease control.

I address recurring themes from golf course superintendents, lawn care professionals, and homeowners, explain where confusion often arises, and clarify how peer-reviewed research should be interpreted instead of relying on anecdotes, marketing claims, or social media shortcuts.

This video focuses on critical thinking in turfgrass management, explaining how to evaluate advice, understand soil and tissue test results, and avoid common reasoning errors when making fertility and pest management decisions.

If you’ve commented on a video, sent an email, or wondered whether advice you see online is actually supported by science, this episode is for you.
