The answer to 'drainage system has weeds' is that weeds growing in your drainage system are a common problem that can indicate underlying issues. Weeds may take root in clogged or slow-moving drainage, indicating a blockage or problem with the system's effectiveness. Symptoms include standing water, slow drainage, and visible weed growth.
To address this, you'll first want to clear out any visible weeds and debris from the drainage system. This may involve using a garden hoe, trowel, or other tools to manually remove the weeds and any accumulated organic matter. If the problem persists, you may need to inspect the drainage pipes and structures to identify and resolve any blockages or other issues. In some cases, calling a professional landscaper or plumber may be necessary to properly diagnose and fix the problem.
