The answer to 'sprinkler system weeds' is that weeds growing around your sprinkler heads are a common issue, often caused by excess moisture, poor drainage, or gaps in your sprinkler coverage. Symptoms include weeds sprouting up around the sprinklers, which can clog the heads and reduce water efficiency. To solve this, you'll need to identify and address the root cause.
If the weeds are isolated to just a few areas, you may be able to DIY by hand-pulling the weeds, adjusting your sprinkler heads to improve coverage, and applying a pre-emergent herbicide to prevent future weed growth. However, if the issue is widespread or you're unsure of the cause, it's best to call in a professional landscaper or sprinkler technician to diagnose and fix the problem.
