What is trimming when using a showerhead nozzle?

• A. A method of cleaning nozzles with water.
• B. A calibration method using test strips.
• C. The technique of walking faster and moving the nozzle back and forth quicker to apply another half rate to the edge of a swath, such as along flower beds or driveways.
• D. A procedure for adjusting spray pressure.

Answer: (C)

Trimming targets the edge of a spray pattern. When using a showerhead nozzle, you finish the swath by moving a bit faster and sweeping the nozzle back and forth more quickly as you reach the boundary, applying about a half-rate to the edge. This creates a treated edge along flower beds, driveways, or other non-target areas without dumping the full rate where it isn’t needed, helping to reduce drift and protect sensitive features while still ensuring the boundary area gets adequate coverage. It isn’t about cleaning nozzles, calibrating with test strips, or adjusting overall spray pressure.
