In learning a turf case history, which question is commonly asked first?

• A. When did this occur
• B. Grass type
• C. Age
• D. Irrigation regimen

Answer: (A)

The first thing to pin down is when the issue began. Understanding the onset helps you anchor the problem in time and connect it to potential triggers like a recent heat spell, drought, heavy rain, a change in irrigation, or a new fertilizer or pesticide event. This timing tells you which causes are plausible and guides the next questions and steps in the diagnosis. Grass type, age, and irrigation regimen are important for management and susceptibility, but they don’t establish the starting point of the problem the way knowing when it occurred does.
