The answer to 'why is my irrigation system overgrown' is that an overgrown irrigation system is often caused by a lack of regular maintenance and inspection. Over time, plants, weeds, and debris can accumulate around the sprinkler heads, valves, and other components, restricting water flow and coverage. This can lead to uneven watering, dry spots, and excessive growth in some areas.
To resolve an overgrown irrigation system, you'll need to clear away any vegetation and debris around the system components. This may involve trimming back plants, pulling weeds, and removing any soil or mulch that has built up. You'll also want to check for any damaged or clogged sprinkler heads and replace them as needed. Regular maintenance, such as seasonal inspections and adjustments, can help prevent the system from becoming overgrown in the future.
