The answer to 'why is my sprinkler system dying plants' is that your sprinkler system may be overwatering or underwatering your plants, causing them to wither and die. Common causes include broken or misaligned sprinkler heads, leaks in the system, improper watering schedules, and incorrect programming of the irrigation controller.
Symptoms of a malfunctioning sprinkler system include wilting, yellowing, or browning of leaves, as well as stunted growth or plant death. To troubleshoot the issue, check for visible leaks, inspect sprinkler heads for proper coverage and function, and review your watering schedule to ensure plants are receiving the right amount of water. If you're unable to resolve the problem, it's best to call a professional landscaper or irrigation specialist to diagnose and repair the system.
