Quick answer: Dry or stressed turf can result from too little irrigation, but it can also come from poor sprinkler coverage, clogged nozzles, low pressure or a failed zone. Before increasing the schedule, determine whether water is actually reaching the affected area.
Check whether the problem follows sprinkler coverage
A sharply defined dry area near a blocked or malfunctioning sprinkler often points to distribution rather than an overall lack of watering.
Inspect the irrigation system first
- Run the affected zone manually
- Check whether every head rises fully
- Look for clogged or misdirected nozzles
- Compare spray distance with nearby heads
- Look for leaks or unusually weak pressure
Then evaluate scheduling
If coverage is uniform and the system operates correctly, adjust watering based on current weather, soil and landscape needs rather than using a fixed year-round schedule.
