The answer to 'why is my irrigation system dying plants' is that there are several common causes, including leaks, clogged sprinklers, improper watering schedules, and mineral buildup. These issues can lead to uneven water distribution, over-watering, or under-watering, which can stress and kill plants.
Symptoms of an irrigation system problem may include wilting, yellowing, or browning plants, as well as wet or dry spots in the lawn. To troubleshoot, check for leaks, clean or replace sprinkler heads, and adjust your watering schedule based on weather and plant needs. If the issues persist, it's best to call a professional irrigation technician to diagnose and repair the system.
