What factor should guide the timing of fertilizer applications when planning two annual applications?

• A. Site use
• B. Soil color
• C. Collector's preferences
• D. Grass species

Answer: (A)

Site use drives when you should fertilize. Different uses create different growth and stress patterns, so timing the two applications to match those needs keeps the turf healthy when it’s most vulnerable and most productive. For a site with heavy use, schedule the first application to support spring green-up and recovery after dormancy, and the second to sustain color and density during the main growing period or to help recover after peak wear. This approach ensures nutrients are available when the grass can use them most effectively, rather than being tied to a fixed calendar.
