The answer to 'irrigation installation has weeds' is that weeds growing in your irrigation system is a common issue, often caused by improper installation or maintenance. Weeds can clog up the system, reduce water flow, and even damage the pipes and sprinklers over time.
Some common symptoms include reduced water pressure, uneven watering, and of course, visible weeds growing around the irrigation components. To solve this problem, you'll need to identify and address the root cause, which could be anything from poor drainage to a lack of weed control in the surrounding landscape.
