The answer to 'why is my sprinkler system bare spots' is that there are several common causes, including improper sprinkler head placement, insufficient water coverage, and compacted soil. Bare spots can occur when certain areas of your lawn are not receiving enough water from the sprinkler system.
Some common symptoms include dry, patchy grass, wilting plants, and visible gaps in your lawn's coverage. To fix this issue, you may need to adjust your sprinkler heads, increase water pressure or runtime, or aerate and loosen the soil in affected areas.
